Some Common Forms Of Neuropathy


Today's post from dressamed.com (see link below) tries to explain what the characteristics of a few sorts of neuropathy are. One of the first things we hear when we try to research neuropathy is, that there are over 100 types and over 100 causes. It generally stops there but most of us want a little more information than just the bare facts, This article looks at probably the 7 most common forms of neuropathy and gives a short description of each. In the confusion after hearing a diagnosis of neuropathy, most people are left bewildered as to exactly what's wrong with them and why. This article helps set a few things straight and hopefully helps many nerve damage patients better understand why they're suffering so much. The authors admit themselves that it's a limited choice but it's better than no choice at all.

The Different Types of Neuropathy 
Posted on May 11, 2016 Posted in Staff Pick by Staff Pick

Neuropathy, also known as peripheral neuropathy, is a disease often associated with diabetes, although there are actually more than 100 known types of neuropathy – each with its own characteristic symptoms, pattern of development, and prognosis. Although there are several “tell-tale” symptoms that seem to afflict all neuropathy sufferers, each version of the disease is different and comes with its own set of problems.

Below are several of the main types of neuropathy, although this is not an exhaustive listing by any means.


DIABETIC NEUROPATHY — Over 30% of all neuropathies can be linked to diabetes, and diabetes is the most common cause of neuropathy in the western world. Both Type 1 and Type 2 diabetes can lead to diabetic neuropathy – high blood sugar levels damage the nerves and neuropathy is one of the outcomes.


IMMUNE MEDIATED/CIDP
— manifestations of neuropathy such as CIDP (Chronic Inflammatory Demyelinating Polyneuropathy) is caused by an abnormal immune system response. In this condition, nerves swell and become irritated due to an immune reaction, eventually damaging the nerves outside the brain or spinal cord with peripheral neuropathy symptoms thus following.


HEREDITARY NEUROPATHY — Diseases like Charcot-Marie-Tooth have been discovered to be inherited and lead to hereditary neuropathy. This condition deals with the role of different proteins in the role of physiology in peripheral nerve conduction.

 
AUTONOMIC NEUROPATHY
— actually a group of symptoms more than a disease itself, autonomic neuropathy concerns damage to the nerves of the body that control every-day functions in the body that are autonomic in nature, such as blood pressure, heart rate, bowel and bladder emptying, even digestion. When the nerves that control or affect these functions are disrupted, these autonomic functions cease to perform normally and can cause many complications.


COMPRESSIVE NEUROPATHY — Known to laymen as a “pinched nerve,” compressive neuropathy often comes about by an accidental injury to the body. Herniated discs, sciatica, arthritis in the spine and spinal stenosis are just some of the ways a nerve can become compressed and cause pain and discomfort to an afflicted sufferer. 


DRUG-INDUCED/TOXIC NEUROPATHY
–– toxic polyneuropathies come about in the human body when nerves are damaged or destroyed by chemicals introduced that have cumulative or highly-toxic effects. These tend to be occupational, chance exposures or intentional, even homicidal ingestions.

There are other forms of neuropathy, including those from infectious diseases such as shingles, as well as from nutritional deficiencies. The best bet for understanding any form of neuropathy that a person may be experiencing is to visit their doctor or a trained neurologist for a consultation.

Is Metabolic Neuropathy Much Different To Other Forms Of Nerve Disease


Today's post from nytimes.com (see link below) is an article that may help clear up one of the many problems people have with the language of neuropathy. A patient new to the disease may be diagnosed in terms that leave him or her bewildered and because the neurological vocabulary used by doctors is so broad, you may not be aware precisely what your diagnosis means in relation to other forms of neuropathy. Take the subject of this article for instance. You'd be forgiven for thinking that 'metabolic' neuropathy is a completely different form of nerve damage to other common neuropathies, when in fact it's another general term describing pretty much the same symptoms and problems that millions of others have. Metabolism (change) is life-sustaining chemical transformations within the cells of living organisms. There is an argument that all neuropathies are metabolic in nature but the word in itself shouldn't confuse you:- if you have metabolic neuropathy, you have neuropathy, in the same way that millions of others have. It's very often used in connection with diabetes and is therefore attached to diabetic neuropathy because that's the most common neuropathic cause. Diabetes is a metabolic disease, because it affects the body’s ability to capture glucose from food for use by the cells. You're probably more confused than ever now (I haven't explained it very well - apologies😓) but the symptoms and treatment are very much the same as other forms of neuropathy, peripheral or not and metabolic or not.


Metabolic Neuropathies
Metabolic neuropathies are nerve disorders that occur with diseases that disrupt the chemical processes in the body.

Causes

Nerve damage can be caused by many different things. Metabolic neuropathy may be caused by:

A problem with the body's ability to use energy, often due to a nutritional deficiency
Dangerous substances (toxins) build up in the body

Diabetes is one of the most common causes of metabolic neuropathies. People who are at the highest risk of nerve damage from diabetes include:

Those with damage to the kidneys or eyes
Those with poorly controlled blood sugar

Other common metabolic causes of neuropathies include:
Alcoholism
Low blood sugar (hypoglycemia)
Kidney failure
Porphyria
Severe infection throughout the body (sepsis)
Thyroid disease
Vitamin deficiencies (including vitamins B12, E, and B1)

Some metabolic disorders are passed down through families (inherited), while others develop due to various diseases.

Symptoms


These symptoms occur because nerves cannot send proper signals to and from your brain:
Difficulty feeling in any area of the body
Difficulty swallowing
Difficulty using the arms or hands
Difficulty using the legs or feet
Difficulty walking
Pain, burning, pins and needles, or shooting pains in any area of the body (nerve pain)
Weakness in the face, arms, legs, or other area of the body

Usually, these symptoms start in the toes and feet and move up the legs, eventually affecting the hands and arms.

Exams and Tests

An exam may show:

Decreased feeling (may affect touch, pain, vibration, or position sensation)
Reduced reflexes (most common in the ankle)
Muscles becoming smaller (atrophy)
Muscle twitches (fasciculations)
Muscle weakness
Loss of movement (paralysis)

Tests used to detect most metabolic neuropathies:

Blood tests
Electrical test of the muscles (EMG)
Electrical test of nerve conduction

Treatment

For most metabolic neuropathies, the best treatment is to correct the metabolic problem.

Vitamin deficiencies are treated with diet or injections. Abnormal blood sugar or thyroid function may need medication to correct the problem. Alcoholic neuropathy is treated with alcohol abstinence.

In some cases, pain is treated with medications that reduce abnormal pain signals from the nerves (duloxetine, gabapentin, pregabalin). Lotions, creams, or medicated patches can provide relief in some cases.

Clinical trials of new medications include antioxidants, neuroprotectants, insulin-like drugs, and aldose reductase inhibitors.

Weakness is often treated with physical therapy. You may need to learn how to use a cane or walker if your balance is affected. You may need special braces on the ankles to walk better.

Support Groups

Outlook (Prognosis)

The outlook mainly depends on the cause of the disorder. In some cases, the problem can easily be treated. In other cases, the metabolic problem cannot be controlled and nerves may continue to become damaged.

Possible Complications 

 
Deformity
Injury to feet
Numbness
Pain
Trouble walking
Weakness

Prevention

Maintaining a healthy lifestyle can reduce the risk of neuropathy.
Avoid excess alcohol use.
Eat a balanced diet.
Visit the doctor regularly to find metabolic disorders before neuropathy develops.

If you already have a metabolic problem, regular doctor visits can help control the problem and reduce the chance of further nerve damage.

Patients who already have metabolic neuropathy can reduce the risk of some complications. A foot doctor (podiatrist) can teach you how to inspect your feet for signs of injury and infection. Proper fitting shoes can lessen the chance of skin breakdown in sensitive areas of the feet.
