Fast facts on neuropathy
Here are some key points about neuropathy. More detail and supporting information is in the main article.
Neuropathy is a common condition.
Neuropathy is a complication of a number of different medical conditions.
Three types of nerve can be involved; autonomic nerves, motor nerves and sensory nerves.
Sometimes single nerves, or nerve sets are affected. Bell's Palsy is a specific example of a neuropathy of the facial nerve, affecting the muscles and skin of the face.
Physical trauma, repetitive injury, infection, metabolic problems and exposure to toxins and some drugs can all lead to neuropathy.
Most cases of neuropathy are found in people who have diabetes. 2,3
With neuropathy as a complication of diabetes, up to 50% of people affected may be completely without symptoms. 4,5
Testing for neuropathy is a routine part of diabetes care.
While neuropathy can't really be treated, the underlying causes can be targeted. 2,6
For toxic causes, removing exposure to a toxin, or stopping a culprit drug, can halt further nerve damage.
What is neuropathy?
Peripheral neuropathy is common.
It is estimated that upwards of 20 million Americans suffer from this illness.
It can occur at any age, but is more common among older adults.
A 1999 survey found that 8-9% of Medicare recipients have peripheral neuropathy as their primary or secondary diagnosis.
The annual cost to Medicare exceeds $3.5 billion.1
The term 'neuropathy' covers a wide area and many nerves, but the problem it causes depends on the type of nerves that are affected:
Sensory nerves (the nerves that control sensation) causing cause tingling, pain, numbness, or weakness in the feet and hands
Motor nerves (the nerves that allow power and movement) causing weakness in the feet and hands
Autonomic nerves (the nerves that control the systems of the body eg gut, bladder) causing changes in the heart rate and blood pressure or sweating
Neuropathy has many causes, and any number of the three nerve types can be affected at any one time.
Mononeuropathy refers to a single nerve being affected
Polyneuropathy means several nerves are affected
