FROM OUR EXPERTS
Years ago a landmark study proved that not all pinched nerves hurt. By looking at multiple cadavers, researchers found many flattened, pinched, crushed nerves that caused no evidence of pain in the person's medical records (Neary and Ochoa 1975). That really puzzled the medical community because the popular thought, at the time, was that all pinched nerves hurt . Since that theory was disproven, scientists have been trying to explain why some nerve damage hurts and some does not.
Within the past 15 years, many studies have shown the effects of inflammation on the nerve. Without any source of physical, mechanical pinching, a nerve can be damaged by the inflammatory chemicals. Such chemicals are equivalent to throwing acid on a nerve. That is why steroid injections work. The steroids block the chemical reaction and cool the nerve. However, some people know that even injections do not help all types of nerve pain. So, there must be more to this puzzle; inflammation is not the only...
Neuropathy - distal median nerve
Pain in the wrist or hand that wakes you up at night
May be severe Pain may be felt in other areas, for example in the upper arm (this is called referred pain)
Sensation changes in the thumb and pointer (index), middle, and part of the ring fingers, such as:
Weakness of the hand that causes you to:
Drop things Have difficulty grasping objects
Signs and tests
Your doctor will examine your wrist and ask questions about your medical history. The examination may show decreased sensation in the thumb side of the hand. This is called the "radial" side. There may be weakness of the thumb and difficulty using it to pinch.
Tests that reveal distal median nerve dysfunction may include:
Nerve conduction tests
Tests are ...
Definition Dementia is a loss of brain function over weeks, months, or years that occurs with certain diseases. It affects memory, thinking, language, judgment, and behavior. Similar changes that occur over hours or a day or two is called delirium or encephalopathy. Metabolism refers to all the physical and chemical processes in the body. Dementia due to metabolic causes is a loss of brain function that can occur with diabetes, thyroid disease, and other metabolic disorders. Causes, incidence, and risk factors How often this condition affects different ages, genders, and races varies based on the disorder that is causing the dementia. Metabolic causes of dementia include: Endocrine disorders, such as Addison's disease or Cushing's disease Heavy metal exposure, such as to lead, arsenic, murcury, or manganese Repeat episodes of low blood sugar ( hypoglycemia ), most often seen in people with diabetes who use insulin Hyperparathyroidism , by causing very high levels of calcium in the blood Hypothyroi...
