What is peripheral sensorimotor axonal polyneuropathy?
What is peripheral sensorimotor axonal polyneuropathy?
Sensorimotor polyneuropathy is a bodywide (systemic) process that damages nerve cells, nerve fibers (axons), and nerve coverings (myelin sheath). Damage to the covering of the nerve cell causes nerve signals to slow or stop. Damage to the nerve fiber or entire nerve cell can make the nerve stop working.
How is peripheral neuropathy measured?
Electromyography (EMG) records electrical activity in your muscles to detect nerve damage. A thin needle (electrode) is inserted into the muscle to measure electrical activity as you contract the muscle.
What is the difference between peripheral neuropathy and polyneuropathy?
Polyneuropathy is when multiple peripheral nerves become damaged, which is also commonly called peripheral neuropathy. Peripheral nerves are the nerves outside of the brain and spinal cord. They relay information between the central nervous system (CNS), and all other parts of the body.
What is the most common cause of polyneuropathy?
The most common form of chronic polyneuropathy usually results from poor control of blood sugar levels in people with diabetes but may result from excessive use of alcohol. or multiple mononeuropathy. It causes abnormal sensations and weakness.
Is axonal neuropathy a disability?
Neuropathy is considered a disability by the SSA. The SSA refers to a medical guide called the Blue Book when evaluating eligibility for Social Security disability benefits.
Is axonal neuropathy degenerative?
Axonal degenerative polyneuropathies are usually symmetrical, and as the disorder progresses, the axons typically degenerate in a distal-to-proximal gradient. Axonal degeneration is the most common type of pathologic reaction in generalized polyneuropathies, and it is often attributed to a metabolic cause.
How does polyneuropathy affect the body?
Polyneuropathy can affect nerves responsible for feeling (sensory neuropathy), movement (motor neuropathy), or both (sensorimotor neuropathy). It may also affect the autonomic nerves responsible for controlling functions such as digestion, the bladder, blood pressure, and heart rate.
What is peripheral neuropathy?
Peripheral Neuropathy. Peripheral neuropathy is a type of damage to the nervous system. Specifically, it is a problem with your peripheral nervous system. This is the network of nerves that sends information from your brain and spinal cord (central nervous system) to the rest of your body. Peripheral neuropathy has many different causes.
What tests are done to diagnose polyneuropathy?
A blood test, urine samples, and biopsy of the area affected by nerve damage (sometimes including your nerves, too) will also help your doctor figure out the cause and extent of polyneuropathy. Other tests may be necessary if your doctor suspects an underlying condition.
What is the global prevalence of peripheral polyneuropathy?
Worldwide, the prevalence of peripheral polyneuropathy varies widely and depends largely on the socioeconomic status and age distribution of the study population, but in the general population ranges from 1-3%, and increases to 7% in those over age 50. 1
