Alzheimer-type dementia - Diabetes Mellitus Factor


Diabetes  mellitus is an endocrine disease where there is diminished insulin action. It can also be referred to as "sugar diabetes", juvenile onset diabetes, Type I diabetes, IDDM (insulin dependent diabetes mellitus), NIDDM (non insulin dependent diabetes mellitus), Type II diabetes and maturity onset diabetes.

Signs and symptoms
  • Insulin dependent diabetes usually begins before the age of 40 with the abrupt onset of symptoms such as thirst, excessive urination, increased appetite and weight loss.
  • Non insulin dependent diabetes usually begins in middle life or beyond, and the typical patient is overweight. The onset of symptoms is more gradual, or there may be no symptoms and diabetes is diagnosed on routine testing.
Establishing onset

If a veteran had diabetes mellitus there would be specific evidence with regard to blood sugar levels and the need for diet, weight loss, insulin or drugs to lower blood sugar levels (eg Daonil, Euglocon, Glimel, Diabinese, Rastinon, Diamicron, Minidiab, Melizide), drugs to help insulin work better (eg Diabex, Diaformin, Glucophage) and drugs to slow the digestion of carbohydrates (eg Glucobay).
