Type 3 diabetes is an ambiguous term sometimes used to describe a proposed link between Alzheimer’s disease in the brain and insulin resistance. Although it is not an officially recognized medical diagnosis like Type 1 or Type 2 diabetes, this condition is based on growing evidence suggesting that insulin dysfunction in the brain may contribute to the development of Alzheimer’s disease.
The brain uses insulin to manage its energy and support cognitive functions such as memory and learning. In Type 3 diabetes, insulin resistance develops in brain cells, reducing their ability to use glucose, leading to dysfunctional and deteriorating brain cells. This is why people with Type 2 diabetes have a higher risk of developing Alzheimer’s disease.
Although the concept of Type 3 diabetes provides valuable insights into the causes of Alzheimer’s, it remains a subject of ongoing research in the scientific community. Some researchers identify Alzheimer’s as a form of specific brain diabetes.
