Denervation processes are strongly associated with the symptoms experienced in post-polio syndrome.

Malnutrition first causes fat loss but may progress to muscle atrophy in prolonged starvation and can be reversed with nutritional therapy. In contrast, cachexia is a wasting syndrome caused by an underlying disease such as cancer that causes dramatic muscle atrophy and cannot be completely reversed with nutritional therapy.

Over half of diabetic patients with ...
