Condition
Neuropathy (Nerve Damage)
When Your Nerves Can’t Talk Like They Used To
Overview
20M+
More than 20 million people in the U.S. are estimated to have some form of peripheral neuropathy, according to the NIH.
70%
Up to 70% of people with diabetes may develop neuropathy during their lifetime.
10%
An estimated 1 in 10 adults over 40 may have peripheral neuropathy, many undiagnosed.
In plain language
Neuropathy refers to damage or dysfunction of the peripheral nerves, leading to symptoms like numbness, tingling, pain, or muscle weakness—most often in the hands and feet. It commonly affects older adults and people with chronic conditions like diabetes.
Neuropathy, also called peripheral neuropathy, is a group of conditions that arise when the peripheral nerves—those outside the brain and spinal cord—are damaged or diseased. These nerves control sensations, movement, and automatic functions like blood pressure and digestion. When damaged, they can misfire, underperform, or stop working entirely.
In older adults, neuropathy often results from chronic conditions such as diabetes, vitamin deficiencies, or medication side effects. It may develop gradually over time or appear suddenly, depending on the cause. The impact can be life-altering, making daily tasks difficult and increasing the risk of falls or injuries. Early recognition and management are key to maintaining quality of life.
Key Information
Review the most relevant symptoms, risk factors, and common care approaches in one place.
Risk Factors
Several factors increase the risk of developing neuropathy, especially in older adults:
Diabetes: The most common cause, particularly if blood sugar is poorly controlled
Age: Risk increases significantly with age
Vitamin Deficiencies: Especially vitamin B12 and folate
Alcohol Abuse: Long-term alcohol use can damage nerves
Medications: Certain chemotherapy drugs and antibiotics
Infections: Shingles, Lyme disease, HIV, and hepatitis C
Autoimmune Conditions: Such as lupus or rheumatoid arthritis
Chronic Kidney Disease: Waste buildup in the body can damage nerves
Symptoms
Neuropathy symptoms vary based on which nerves are affected:
Sensory Nerves
Tingling or numbness in hands and feet
Sharp, stabbing, or burning pain
Increased sensitivity to touch
Loss of coordination or balance
Motor Nerves
Muscle weakness
Difficulty walking or performing fine motor tasks
Autonomic Nerves
Dizziness or fainting
Digestive issues like constipation or diarrhea
Abnormal sweating
Changes in heart rate or blood pressure
Treatments That May Help
Start with the options that have more supporting research and then review the details with your care team.
Treatment Option
Acetyl-L-Carnitine
Acetyl-L-carnitine (ALCAR) is an amino-acid-derived nutrient that helps the body convert fat into energy. It supports healthy nerve function and may enhance memory and alertness in older adults experiencing fatigue or mild cognitive changes.

Treatment Option
Alpha-lipoic Acid
Alpha-lipoic acid (ALA) is a natural antioxidant that supports nerve function, glucose metabolism, and healthy aging. It helps protect cells from oxidative stress, which contributes to nerve pain and fatigue.

Treatment Option
Alpha-GPC (Alpha-glyceryl phosphorylcholine)
Alpha-GPC is a highly bioavailable form of choline that efficiently crosses the blood-brain barrier. It supports acetylcholine synthesis for memory and learning while also promoting growth hormone release.

Treatment Option
Cayenne Pepper
Cayenne pepper, a spicy red chili derived from the Capsicum annuum plant, contains a compound called capsaicin known for its warming and pain-relieving properties. Used topically or as a dietary supplement, it supports healthy circulation, reduces inflammation, and helps ease joint and muscle pain — especially beneficial for older adults managing arthritis or nerve discomfort.

Treatment Option
Decompression Therapy
Decompression therapy uses controlled traction to relieve pressure on the spine and nerves. It can help older adults manage back pain, sciatica, or herniated discs in a noninvasive way.

Treatment Option
PDE5 Inhibitors
PDE5 inhibitors are prescription medications that relax blood vessels and improve blood flow throughout the body. They are commonly used to treat circulation-related issues and enhance vascular health in older adults when prescribed by a healthcare provider.
