New thinking on peripheral neuropathy

Doctors are learning that neuropathy can cause many more problems than just numbness and tingling in the feet and hands. Neuropathy of the autonomic nerves to the heart or blood vessels can cause low blood pressure, perceived as chronic fatigue and faintness or dizziness. Damage to nerve fibers serving the gastrointestinal tract may cause bloating, nausea, digestion problems, constipation, or diarrhea. These are often labeled irritable bowel syndrome. Autonomic neuropathy less often affects the bladder and sexual function. (Locked) More »

Fatty liver disease: An often-silent condition linked to heart disease

As many as one in four Americans has a potentially dangerous accumulation of fat in the liver. Known as nonalcoholic fatty liver disease, it is closely linked to obesity and diabetes and may boost heart disease risk. The milder form of the disease, nonalcoholic fatty liver (NAFL), can progress to a more serious condition called nonalcoholic steatohepatitis (NASH), in which the liver cells are inflamed and injured. The plant-focused Mediterranean diet, which helps prevent heart disease, may slow the progression of fatty liver disease. Other key lifestyle changes include weight loss and regular aerobic exercise.

Closing in on tinnitus treatments

Tinnitus is a ringing in the ears that occurs with age. It may be triggered by impaired hearing, leading to diminished sound impulses moving along the auditory nerve between the ear and the brain. In some people, the brain tries to compensate for this loss of input by turning up internal volume and tuning into background sounds in the brain. Tinnitus can be difficult to treat. There’s no way to measure it directly, which is needed for diagnosis and effective treatment. Researchers are working to identify a physical signature for tinnitus by using measurements of the pupils and brain activity. More »
