Peripheral Neuropathy

What is Peripheral Neuropathy?

Peripheral neuropathy is a condition that occurs when the peripheral nerves—those outside the brain and spinal cord—are damaged. This damage can affect  the nerve fibers (axons) that carry signals and the protective covering around them (myelin sheath), disrupting normal nerve function. As a result, signals may become interrupted, or completely blocked, leading to problems with sensation, movement, or organ function.

Types of Peripheral Neuropathy

Peripheral neuropathy is one of the most common neurological disorders. There are more than 100 known types, each with different causes and symptoms. Some affect sensory nerves, others target motor or autonomic nerves, and many involve a combination. The type of neuropathy often determines how it progresses and how it’s treated. The following are some of the main types of peripheral neuropathy.

Sciatica

damage to the sciatic nerve which runs from the lower back to the feet

Cervical Radiculopathy

damage to the nerve root in the neck

Carpal Tunnel Syndrome

damage to the sciatic nerve which runs from the lower back to the feet

Post Herpetic Neuralgia

nerve damage due to shingles infection

Lumbar radiculopathy

damage to the nerve root in the lower back

Alcoholic neuropathy

nerve damage due to excessive alcohol intake

Diabetic peripheral neuropathy

nerve damage due to diabetes

Symptoms of Peripheral Neuropathy

The symptoms of peripheral neuropathy vary depending on whether the damage involves motor nerves (which control muscle movement), sensory nerves (which transmit sensations like pain, temperature, and touch), or autonomic nerves (which regulate involuntary functions like heart rate, digestion, and blood pressure).

Motor Symptoms
Problems with movement and muscle control:
Muscle weakness Trouble with coordination or balance Muscle cramps Muscle twitches Shrinking or thinning of muscles Feeling stiff Reflexes that are slower or don’t work
Sensory Symptoms
Problems with feeling or touch:
Numbness Tingling or "pins and needles" feeling Loss of sensation Unusual pain or tenderness even with light touch
Autonomic Symptoms
Problems with automatic body functions:
Feeling dizzy or fainting Issues with bladder or sexual functio Sweating too much or not enough Trouble with digestion or stomach problems

The diagnosis of peripheral neuropathy
generally involves the following:

A general health check that may include:

  • Blood tests – to detect vitamin deficiencies, diabetes, or immune dysfunction.
  • Imaging tests (CT/MRI) – to identify structural causes like herniated discs or tumors.
  • Nerve function tests (EMG/NCS) – to measure electrical activity and signal speed in nerves.
  • Biopsies – skin or nerve samples to assess microscopic nerve damage.

Gathers detailed information about symptoms, lifestyle, alcohol use, exposure to toxins, medications, and family history of neurological conditions to help identify possible triggers or contributing factors.

Evaluates nerve function by testing reflexes, muscle strength and tone, sensation (touch, pain, temperature), coordination, and balance to detect signs of nerve damage.

Peripheral nerves have the ability to repair themselves and regenerate after injury.1

What are nucleotides?

Nucleotides, including Uridine monophosphate (UMP) and Cytidine monophosphate (CMP), are essential building blocks of nucleic acids¹. As semi-essential nutrients, the body cannot produce enough in specific situations, including nerve injury, necessitating dietary intake. However, limited food sources can make it challenging to meet these requirements through diet alone2,3.

Nerve Regeneration and Nucleotides

In certain cases, peripheral nerves have the ability to regenerate and recover function after injury, with the repair of the myelin sheath being critical for effective nerve function and signal conduction¹. Since nerves cannot produce all necessary components to facilitate the nerve regeneration process themselves, including nucleotides, an external supply is important to provide the substrates needed to accelerate this process¹.

Mode of Action

The unique combination of uridine and cytidine helps to rebuild the nerve cell and myelin sheath¹
