Summary: One-fifth of the US population is living with chronic pain, and some of them with high impact chronic pain. A new study shows that poorly managed chronic pain is a leading cause of faster cognitive decline, memory loss, and thus increased Alzheimer’s risk. Further investigation found that people with low socioeconomic status were particularly at risk due to healthcare disparities. The study also suggests that these health disparities may partially explain the higher prevalence of Alzheimer’s in black Americans. Hence, the study highlights the need for equal access to chronic pain treatment for various population groups.
Almost half of all adults may experience prolonged episodes of pain in their lifetime. However, data suggests that 20% of the population in the US continues to live with chronic pain at any given time, and these are massive numbers. Even worse, 8% of adults have high-impact chronic pain, and most have to live with it due to poor pain management.
Chronic pain is distressing, to say the least. However, in recent years, doctors have started to realize that chronic pain is also responsible for an increased risk of many chronic health disorders. For example, those living with poorly managed chronic pain are more likely to develop high blood pressure, heart disorders, depression, sleep disorders, and more. Now the new study suggests that chronic pain may be a risk factor for cognitive decline. This finding is especially relevant, considering the rise of dementia. Dementia is now among the leading causes of premature death and disability, affecting millions of lives.
The new study was published in the Journal of Alzheimer’s Disease. The study carried out detailed check-ups of 147 adults between the ages of 45 and 85. Researchers focused particularly on sociodemographic information and cognitive assessment and used MRI brain scans. They found that pain increased dementia risk, particularly in those with low education levels, low income, and thus with poor access to healthcare. In addition, they found that compared to those with better socioeconomic and education status, these individuals demonstrated 4% less gray matter. Thus, these findings were not merely subjective and were supported by objective data.
Of course, losing gray matter with aging is a common phenomenon. Early studies show that people gradually start losing gray matter as they age. This process generally begins in the 50s or 60s in different individuals. Generally, this decline is about half a percent each year. Thus, 3-4 percent equates to 6 to 8 years. It means that the brain of socially and economically deprived individuals age much faster. However, what is worrisome is that most people are diagnosed with conditions like Alzheimer’s in their 50s or later. This reduced gray matter in socially deprived individuals also suggests that they are at a greater risk of developing Alzheimer’s.
Researchers have also been focusing on how various stressors may contribute to an increased Alzheimer’s risk. For example, they found that the risk of developing dementia is almost twice as high in blacks compared to whites. Hence, this study found that this difference is not explained solely by genetics or ethnicity. Instead, it seems that health disparities are also an important contributing factor. These kinds of disparities lead to higher pain and stress exposure and thus resulting in faster brain aging, memory issues, and a greater risk of Alzheimer’s in blacks compared to whites.
Moreover, the study also suggests a relationship between pain intensity and brain aging. It appears that the risk of faster brain aging is proportionate to the pain intensity. It means that those with poorly managed chronic pain are more likely to develop dementia. This is not the first study. An early study that was done in 2017 also had similar kind of findings. It found that those older than 60 and living with chronic pain were more likely to see a sharp decline in their cognitive abilities.
However, there is some good news for those living with poorly treated chronic pain. A study in 2009 found that treating chronic pain well may even help reverse some of the changes in the brain. All these findings highlight the importance of managing chronic pain and providing sufficient relief.
Summary: The release of hormones is the way body counters pain and stress. Thus, now researchers think that using hormones for pain relief may be a good approach, as it helps treat the root cause. Doctors have long used corticosteroids for pain management. However, they have now discovered that other hormones like HCG, oxytocin, progesterone, estradiol, and testosterone can also help relieve pain. They are also exploring the role of over-the-counter neurosteroids in pain management, like DHEA. Hormones are good in the way that they lower neuroinflammation and promote neuro-regeneration.
The current approach to chronic pain treatment is not helping people adequately. However, there is something that medical science still has to learn. Some researchers think that this missing link is the hormones. Human body produces many hormones that promote healing and the body’s natural defenses. Moreover, in recent years, researchers have discovered some new hormones like neurosteroid (NS). Hormones differ from painkillers or opioids in the way that they help treat the root cause of pain.
What doctors are offering to date in many cases is just symptomatic relief, without any perspective of a complete cure. However, this is far from a perfect approach. The use of hormones to treat painful conditions is not new, and doctors have used some hormones to manage pain for a long time. For example, corticosteroid injections into the joints can help reduce pain and inflammation for a long, and they are pretty safe. In addition, short-term corticosteroids use to provide relief in conditions like neuralgia and arthritic flares.
Neurosteroids are naturally produced in the brain and act on different brain cells like neurons glial cells. They have an intrinsic ability to reduce pain sensation. Unfortunately, these compounds also suppress neuroinflammation and promote neurodegeneration. Researchers have identified many neurosteroids like pregnenolone (PREG), dehydroepiandrosterone (DHEA), estradiol, progesterone, and even testosterone.
Many animal studies show that neurosteroids can help in many ways. They suppress the overactivity of the brain’s immune cells or glial cells, protect the brain from further damage, and at the same time, they boost neuro-regeneration. For example, studies in rat models show that PREG and DHEA can promote the healing of damaged spinal cords. At present, there are two types of neurosteroid therapies, the first is replenishment therapy, and another is using these hormones at supraphysiological levels.
For pain treatment, there are prescription hormones and non-prescription hormones. Thus, doctors may use prescription hormones like testosterone, progesterone, and estradiol to treat pain. Or they may recommend hormones that are readily available without a prescription, like DHEA and PREG.
When it comes to using prescription hormones for pain, there could be many ways. However, experts recommend using them intermittently to avoid adverse effects. On the other hand, over-the-counter hormones like DHEA and PREG are suitable for regular and prolonged use.
The human body has numerous hormones, and doctors are still exploring their benefits in pain management. Thus, for example, human chorionic gonadotropin (HCG) is a potent hormone that raises testosterone, progesterone, and estradiol levels. Studies show that it can be pretty good for pain management.
Further, researchers are exploring newer ways in which various hormones can help. For example, doctors have known for a long that corticosteroids are good for suppressing inflammation and, thus, pain. However, now they have realized that corticosteroids may also act on the brain and help reduce neuroinflammation. Therefore, they may have a particular role in managing chronic pains. In addition, it appears that hormones like prednisone, triamcinolone, and hydrocortisone are pretty good for neuroinflammation.
Moreover, corticosteroids appear to help manage neuroinflammation at much lower dosages. Hence, their intermittent use at low dosages may help reduce neuroinflammation and provide chronic pain relief or even intractable pains. Another surprising discovery is the role of oxytocin in pain management. Oxytocin is known to act on the brain and alter mood and behavior. However, new studies show that it may also help manage pain. It can act on specific brain centers and thus reduce pain sensation. The human body naturally releases oxytocin during periods of stress or pain.
Oxytocin is quite a potent pain reliever, acting on the same receptors as opioids. However, it also means that oxytocin is not helpful to those using opioids for pain relief. To sum up, neuroinflammation is one of the significant causes of chronic or intractable pain. It now appears that using hormones instead of painkillers or painkillers may be a better approach to pain management. Moreover, many neurohormones are pretty safe for prolonged use and can help treat the root cause of pain.
Summary: Studies show that doctors often fail to help those living with chronic pain, as they are living with multiple chronic ailments. These chronic overlapping conditions (COPCs) are more challenging to manage than chronic pain caused by a single health issue. Hence, a patient may simultaneously have IBS, arthritis, fibromyalgia, depression, and other issues. However, due to a shortage of pain specialists, one doctor is treating one disease, and the other specialist manages another condition. This results in inadequate pain relief. Moreover, doctors fail to manage other symptoms like mood issues, sleep disorders, and more associated with COPCs.
Chronic pain is a significant problem and isn’t easy to manage. Many people need to take painkillers for years, and yet they do not get adequate symptomatic relief. Not to say that in many cases, doctors are not able to cure the condition. There are many reasons why chronic pains are so difficult to manage and cure. One of the less realized or neglected reasons is the presence of multiple ailments. Doctors tend to treat the most common causes of pain; however, they may miss other less significant causes coexisting with that one primary cause. It is a condition called chronic overlapping pain conditions (COPCs).
COPCs are more common in females, and thus they are more likely to present with pains that are difficult to diagnose and treat. In addition, chronic pain is often associated with other signs and symptoms like mood swings, fatigue, sleep disorder, and cognitive disorders in women. When multiple conditions exist, they influence each other, thus worsening the pain. In addition, they amplify the impact of each other. This means worsening systemic and localized pain, reduced treatment effectiveness, poor health, and psychological outcomes, increased disability, and markedly diminished quality of life.
Further worrisome is the trend. Even in young Americans, COPCs are quite common. However, this number rises to 75% in those older than 65 years of age. It seems that most people are living with multiple chronic and painful conditions. Doctors say that to manage chronic pain effectively, we need to develop a better understanding of COPCs. We need to stop looking at individual pain causes and instead consider COPCs a complex multisystem illness.
COPCs cause two kinds of issues: generalized sensory sensitivity causing increased sensitivity to pain and internal symptom, and hyperalgesia in multiple body regions. Additionally, the person suffers from SPACE (sleep disturbances, pain that is widespread, affect is negative, cognitive dysfunction, and energy depletion). One of the reasons why COPCs remain so poorly identified and treated is the deficit of pain management specialists in the US. It means that people living with multiple health conditions are treated by different specialists. For example, one doctor may treat irritable bowel syndrome (IBS), other urogenital disorders, and yet another jaw pain.
Another challenge in treating these conditions is that each patient requires a personalized treatment approach, as everyone lives with different sets of painful conditions. Thus, one may be living with diabetes, low back pain, and cystitis, and another with IBS, depression, and sleep disorders. Researchers say that managing such patients requires different skills, and doctors must focus on detailed history. Moreover, doctors should not focus only on the pain, but they must also learn about other issues like sleep problems, mood, cognition, and fatigue. In addition, they may try to learn more about sexual dysfunction, quality of life, and more.
Treatment of these conditions must start with US FDA-approved drugs for ten major COPCs (chronic low back pain, migraine, fibromyalgia, endometriosis, cystitis, IBS, and so on). When treating these conditions, doctors need to choose approaches targeting the central nervous system, including medications like anticonvulsants, antidepressants, muscle relaxants, and other medications.
Additionally, doctors would need to consider non-pharmacological means like physical and occupational therapy to improve patients’ functionality. Psychological counseling is another aspect to consider. As people with COPCs are living with mood disorders and maladaptive thinking.
Finally, doctors need to explore complementary medicine, including acupuncture, massage therapy, yoga, and chiropractic care.
Summary: Chronic groin pain is a significant issue in those who have undergone surgery for an inguinal hernia. This often leads to patients blaming the mesh companies. It also causes prolonged distress and trauma to the patients. However, doctors often fail to treat such pains.
Studies suggest that in many such instances, pain is due to some other underlying cause like low back pain or trauma, and only in small cases is it secondary to surgical intervention. Thus, doctors recommend careful history taking to identify the cause of this pain. Additionally, experts also recommend exploring nontraditional treatments for chronic pain, like psychedelic-assisted psychotherapy.
In the annual meeting of the American Hernia Society, 2021, Doctor Brian P. Jacob discussed the significance of understanding chronic groin pain and finding its solution using innovative treatment methods.
Groin pain is a pretty common complaint among those living with inguinal hernia. Quite often, this hernia is treated using mesh repair. It is a relatively simple surgical procedure that provides instant relief in 70% of cases. However, experience shows that one-third of patients continue to experience pain. Quite often, they blame mesh for their continued pain, and doctors fail to understand the cause of such pain.
Dr. Jacob has multiple recommendations for surgeons and pain clinics for managing such pain. He also underlined the importance of understanding this pain. Since this continued pain after surgery is a source of significant distress. It makes patients quite angry, and they also go on blaming the mesh companies for their pain. Not only that, untreated patients undergo significant trauma, resulting in PTSD.
Dr. Jacob says that there are two sources of these chronic pain in those who had hernia surgery. The first and often overlooked cause of this chronic pain is some pre-existing condition in the patient, like a back issue or some other trauma. Unfortunately, doctors often fail to notice or identify these causes, and the patient continues to associate this pain with the surgery.
The second reason for such chronic pains is naturally the surgery itself, which means unintentional fault. Unfortunately, however, surgeons are often hesitant to accept that something has occurred due to the surgical procedure, and this negation only adds to the patient’s frustration.
There cannot be more frustrating for the patient than doctors failing to recognize the cause of pain. Thus, such patients have to tolerate this continuous chronic pain, and at the same time, they undergo severe emotional trauma. Worst in this situation is the fact that these patients largely remain untreated.
Thus, Dr. Jacob recommends that doctors accept that their patient is going through severe and chronic pain and focus on finding the solution. It is true that identifying the cause of such chronic pain is challenging. Nevertheless, they need to treat such patients. He particularly recommends focusing on alternative therapies.
Dr. Jacob advocates exploring alternative treatments for chronic pain. This does not essentially mean supplements. It also means exploring uncommon approaches to pain management. The traditional way of pain management appears to mask the pain origins and provide temporary relief.
Unlike traditional painkillers or opioids, doctors must explore non-pharmacological therapies like meditation, mindfulness, yoga, pilates, and even psychotherapy. Dr. Jacob is also a proponent of psychedelic-assisted psychotherapy.
When it comes to psychedelic-assisted psychotherapy, this therapy mainly uses ketamine these days. Ketamine is proven to work, safe, and supported by many clinical studies. The results of ketamine-assisted psychotherapy are pretty promising.
However, Dr. Jacobs also favors exploring other ways of psychedelic-assisted psychotherapy. Among the other agents, psilocybin and MDMA are pretty promising. These medicines have excellent safety profiles and maybe even better than ketamine. Moreover, these therapies not only treat pain but also help overcome anxiety, depression, PTSD, and other severe mental health issues.
In short, Dr. Jacob strongly recommends taking a thorough history of patients with groin pains. The doctor should not assume that this pain is only due to an inguinal hernia. In many cases, other unidentified causes of groin pain remain undiagnosed. Additionally, in some cases, the cause of chronic pain could be a surgical procedure. In all these conditions, doctors must understand the patient’s pain and focus on treating chronic pain using various methods.
Summary: The incidence of low back pain is increasing due to the aging population in the US. One of the ways to help those living with low back pain (LBP) is by providing physical therapy (PT). However, there has been controversy regarding when to introduce PT. A retrospective study of about a million US adults diagnosed with LPB shows that early PT introduction is associated with better outcomes, fewer clinic visits, and lesser healthcare expenses. Most adults would experience low back pain in their lives. For many, the condition may become chronic. And, thus for some adults, managing low back pain may transform into a lifelong struggle. For those living with chronic low back pain, it means frequent visits to the doctors and higher healthcare expenses compared to those who do not have low back pain. Moreover, managing low back pain remains relatively challenging. It means that those living with the condition often visit different specialists like physicians, pain specialists, orthopedists, chiropractors, and so on. All this means much distress and higher expenses. Though the benefits of PT (physical therapy) in low back pain are well known, such interventions are often avoid in the early phase. This is because doctors fear that providing PT in the early stage may make things worse. In addition, there is a risk that PT may do more damage to the already weak and damaged spine. However, now some researchers have started questioning this approach. They think that perhaps the acute phase of low back pain is the right time to provide PT. They believe that delays in PT mean lower effectiveness and slow recovery. It also means that the condition is more likely to become chronic in most cases. To understand if early PT introduction is associated with better outcomes, researchers in the US carried out a retrospective study. The study analyzed the data of almost a million adults aged 18 to 64 years who reported low back pain (LBP) between 2010 and 2014. In the study, they identified that out of these adults, about 11% received early PT. In the study, researchers found that early PT was good in every way. Thus, it resulted in much better clinical outcomes and fewer visits to pain specialists, emergency departments, imaging centers, orthopedists, and more. In most cases, it resulted in 50% fewer visits to various doctors. These benefits are significant. Fewer visits to doctors and clinics naturally mean lower healthcare costs. The study found that those with early PT had fewer procedures, resulting in much savings. Researchers found that lower visits to doctors and saving in healthcare costs were significant and seen both in the short and long term. Thus, researchers analyzed that those with early PT had lower healthcare costs at 30 days and after one year of the diagnosis. This massive study puts an end to all the controversies regarding early PT in LBP. It clearly shows that early PT is the best way forward. The US population is aging, and issues like low back pain are only expect to increase. Moreover, the incidence of metabolic disorders is also rising. More people are now living with obesity and have a sedentary lifestyle. It means that the incidence of low back pain is expect to skyrocket. All this means that the healthcare system should be better prepared to help those living with low back pain. Findings in this study show that early PT can make a significant difference. Moreover, PT is not just good for low back pain. It may also help improve metabolic health. Therefore, researchers now strongly recommend starting PT early in those newly diagnosed with LBP. It is our mission to bring real hope and transformational change to patients who would otherwise be consign to a lifetime of medications, doctor’s visits, and suffering. We expose misaligned incentives and return the power of health to the individual, we believe empowered individuals change their communities. We use a combination of lifestyle intervention, medication management, and emerging scientific research to help our patients. When you are ready or have questions, reach out.

Summary: Inflammation is a defensive reaction that promotes healing. However, inflammation also causes acute pain. Thus, it is a common practice to use anti-inflammatory drugs to suppress pain and for chronic pain treatment. However, studies show that suppressing inflammation reduces the activity of neutrophils and thus increases the risk of chronic pain. Hence, experts recommend changing the approach toward joint inflammation treatment.
Inflammation is a defensive reaction that is essential for tissue regeneration. However, uncontrolled inflammation may cause more damage than good. Inflammation causes local redness and, more importantly, severe pain. Thus, doctors are quick to prescribe anti-inflammatory drugs for chronic pain treatment, forgetting that pain is also a sign of undergoing repair processes. Hence, medications like non-steroidal anti-inflammatory drugs (NSAIDs) are among the most used drugs.
As more and more people are nowadays experiencing chronic pain, researchers are becoming increasingly interested in why some people are more likely to experience such health issues. It appears that one of the reasons could be aggressive joint inflammation treatment.
It does not mean that one should not treat inflammation, but one uncontrolled inflammation. However, aggressive medication for inflammation must be avoided, as doing so would also suppress healing processes and thus make the conditions chronic.
Of course, these findings put into question some usual ways of treating pain. It means doctors and people should be careful during chronic pain treatment and joint inflammation treatment. But, of course, not all painkillers suppress inflammation. Thus, opioids or acetaminophen would not suppress inflammation. But, drugs like ibuprofen and diclofenac would suppress inflammation and make the conditions chronic.
The new study was published in Science Translational Medicine. In the study, researchers explored the pain mechanism in both mice and humans. In addition, they found that white blood cells called neutrophils play an important role in fighting infections, tissue regeneration, and healing.
The study found that those living with chronic pain were individuals who had developed specific changes in genes, which altered the activity of white blood cells in their bodies. In addition, these changes seem to alter the activity of neutrophils, thus putting these individuals at a greater risk of chronic pain.
It is essential to understand that neutrophils dominate the early stages of inflammation and set the stage for tissue repair. However, if these early processes are disturbed through aggressive anti-inflammatory therapy, the condition is more likely to become chronic.
In the study, when researchers blocked neutrophils in mice, they found that it prolonged the pain by as much as ten times. In addition, they found that treating pain and inflammation with dexamethasone or diclofenac produced similar results. Though both drugs were quite effective in suppressing pain in the early stages, they ultimately increased the risk of chronic pain1.
This is not the first study with such findings. Earlier, a study was done on half a million people in the UK. It found that those who took medication for inflammation more commonly and treated inflammation aggressively were more likely to experience pain two to ten years later. Such an effect was not seen in those who chose acetaminophen or anti-depressants.
There are several implications of this study. Particularly considering that NSAIDs are often the treatment of choice in different inflammatory and painful conditions. Moreover, some NSAIDs are even available as over-the-counter drugs. It means that doctors must reconsider how they treat pain, and patients must be aware of the risks of aggressive anti-inflammatory therapy.
Of course, such treatments feel good in their early stages as they provide quick relief. But as the studies show that such a treatment approach may considerably increase the risk of chronic pain.
Understanding that suppressing all kinds of inflammation is not a good idea is vital. After all, it is part of the healing process. It is crucial to tolerate some pain, let the body heal itself, and wait for pain resolution. If the pain is severe, it is better to use medications that suppress pain sensation but not inflammation.
Summary: Doctors frequently use antidepressants to manage low back pain, especially if non-steroidal anti-inflammatory drugs fail to help. However, experts think that evidence in favor of antidepressant use for low back pain in men and women is weak, and most studies showing benefits were industry sponsored. The new systemic review combining data from 33 clinical studies found no sound evidence in favor of using antidepressants for chronic back pain.
Low back pain is among the leading causes of chronic pain and disability. Those with low back pain may not only have to live with pain for a long, but relapses are quite common even if such pain is treated successfully.
The primary way to manage low back pain in men and women is with non-steroidal anti-inflammatory drugs (NSAIDs) and physical therapy. However, these treatments do not work for many. In such cases, doctors have to consider various other treatment options.
Studies show that those experiencing low back pain are often living with many comorbidities. For example, mood and emotional disorders are pretty common among those living with low back pain. Therefore, no surprise that antidepressant use is pretty common in low back pain.
Additionally, it is worth noticing that most treatment guidelines also recommend using antidepressants as one of the treatment options for chronic back pain and even other joint pains. However, despite the recommendation, there is limited evidence that these medications work.
A new systemic review of 33 clinical trials concluded that there is little evidence in favor of antidepressant use in low back pain. Nonetheless, doctors continue to use these drugs widely. This is worrisome, considering that antidepressants have many side effects. Hence, it is quite likely that the harm from such a therapeutic approach may be greater than the benefit.
In the latest systemic review, researchers analyzed the benefit of antidepressants in low back pain and osteoarthritis in those who did not benefit from analgesic drugs. Systemic reviews are special kinds of studies that sum up the data from multiple clinical trials. Thus, systemic review conclusions have significant importance.
The researchers say that they did find some benefits from antidepressants. However, the chances of benefit were slim, and any benefit was low. Thus, for example, they found that antidepressants may help with osteoarthritis. However, only one in ten patients may expect to benefit from such a drug therapy after three or more months of prolonged use.
Here it is worth noting that many of those studies that demonstrated some benefit from antidepressants were industry-sponsored. Therefore, researchers say there is a need for more extensive clinical trials that are not funded by the industry.
Moreover, experts noted that many of these guidelines regarding the use of antidepressants are based on outdated data and studies. Hence, many of these studies have methodological flaws.
In the present systemic review, researchers included 33 clinical trials with a total sample size of 5000 adults living with low back pain, neck pain, sciatica pain, and hip or knee osteoarthritis2.
In the study, researchers used a 0–100-point scale to assess the benefit of antidepressants for back pain. Here zero means no pain at all. Researchers say that about a 10-point benefit on this scale may be accepted as clinically significant. However, in the study, researchers found that antidepressants had merely 5.3 points of benefit compared to placebo. This benefit is just too small to justify the regular use of antidepressants for chronic back pain. Even for osteoarthritis, this benefit was 9.7, which is barely acceptable.
Therefore, researchers concluded that there is insufficient evidence to justify the use of antidepressants for managing low back pain.
These are not the first findings of this kind. Many early studies have also expressed similar sentiments, saying that doctors should explore other treatment options for those living with chronic low back pain, including non-pharmacological means.
Experts have gone further, saying that most medications have a limited role in chronic back pain treatment, something that doctors must understand. The use of opioids, cannabis, gabapentinoids, and antidepressants is especially controversial, as harm from these drugs outweighs potential benefits.
Diabetes is a chronic metabolic disorder characterized by high blood sugar levels resulting from the body’s inability to produce or properly use insulin. Diabetes is of two types: type 1 and type 2. Type 1 diabetes is an autoimmune disorder that typically occurs in children and young adults, where the body’s immune system attacks and destroys the insulin-producing cells in the pancreas, leading to insulin deficiency. On the other hand, type 2 diabetes usually develops in adults and is caused by a combination of insulin resistance and decreased insulin secretion by the pancreas. One of the most common complications of diabetes neuropathy, which refers to damage or dysfunction of the nerves that transmit signals between the brain, spinal cord, and other parts of the body. Neuropathy can affect various types of nerves, including sensory, motor, and autonomic nerves, leading to a wide range of symptoms such as numbness, tingling, pain, weakness, loss of balance, and digestive problems. Diabetic neuropathy is a progressive condition that typically develops over time, and its severity and progression may vary among individuals. The exact mechanisms underlying diabetic neuropathy are not fully understood, but high blood sugar levels, oxidative stress, inflammation, and metabolic imbalances are thought to contribute to nerve damage. Treating diabetic neuropathy can be challenging, as there is no cure for this condition, and the available treatments aim at managing symptoms and slowing down the progression of the disease. Some of the treatment options include medications such as pain relievers, antidepressants, and anticonvulsants, which can help alleviate pain and improve nerve function. Lifestyle modifications such as maintaining a healthy diet, engaging in regular physical activity, and quitting smoking may also help improve symptoms and prevent complications. In severe cases, procedures such as nerve decompression surgery or spinal cord stimulation may be considered. However, there are several challenges involved in treating diabetic neuropathy. Firstly, the symptoms of neuropathy may overlap with other conditions, making diagnosis and management difficult. Secondly, there is no standardized treatment protocol for diabetic neuropathy, and the effectiveness of available treatments may vary depending on individual factors such as the type and severity of neuropathy, age, and comorbidities. Thirdly, some of the medications used to treat neuropathy may have side effects, interactions with other medications, and may not be suitable for all patients, especially those with underlying medical conditions. Lastly, the cost of treatment can also be a barrier for some patients, as some of the medications and procedures used for neuropathy can be expensive and may not be covered by insurance.
The study, published in the Nature, is about how the levels of certain non-essential amino acids (NEAAs), specifically serine and glycine, are consistently reduced in patients with metabolic syndrome, diabetes, and other peripheral nerve disorders. The researchers found that this deficiency in serine and glycine may contribute to the pathogenesis of diabetes and other associated complications. The study was conducted on diabetic mice, where the researchers observed that aberrant serine homeostasis was responsible for the deficiency in serine and glycine levels. They developed a test, called the serine tolerance test, to measure serine uptake and disposal in mice. By restricting the intake of dietary serine and glycine in young mice and feeding them a high-fat diet, they were able to accelerate the onset of small fiber neuropathy, a type of nerve damage that is common in people with diabetes. However, when they normalized the levels of serine by providing dietary supplementation and used a drug called myriocin to mitigate dyslipidemia (abnormal fat levels), they found that neuropathy was alleviated in diabetic mice. The researchers conclude that systemic serine deficiency and dyslipidemia are risk factors for peripheral neuropathy and may contribute to the pathogenesis of diabetes and its complications. They suggest that dietary supplementation with serine and glycine, as well as the use of drugs that mitigate dyslipidemia, could be potential therapeutic strategies for managing peripheral neuropathy in people with diabetes. In summary, this study highlights the importance of non-essential amino acid metabolism, specifically serine and glycine, in the pathogenesis of diabetes and its associated complications. It also suggests that manipulating the levels of these amino acids and mitigating dyslipidemia could be potential therapeutic strategies for managing peripheral neuropathy in people with diabetes.
