The two most common forms of diabetes mellitus are type 1 and type 2. Type 1 diabetes mellitus is characterized by an absolute insulin deficiency that is associated with a large number of metabolic changes. This type of diabetes requires insulin therapy. Without insulin, this disease is fatal. The far more common form of diabetes mellitus nowadays is type 2 diabetes mellitus. It is characterized by insulin resistance. For a number of years drugs have been available that can be used to treat this form of diabetes in a multimodal manner. These therapy options can not only improve metabolic control, but also prevent cardiovascular events. Different cognitive alterations associated with diabetes mellitus can be distinguished. On the one hand, the change in glucose homeostasis itself leads to cognitive alterations, i.e. blood sugar levels that are too\n          high or acutely too low are regularly associated with significant impairments in mental performance, including loss of consciousness. But not only the momentary blood sugar levels, but also long-term changes in glucose metabolism might lead to neurodegeneration and even dementia in a way that has not yet been fully understood. Insulin or insulin-like molecules have important effects in the central nervous system. In the last decades, it has been shown that insulin receptors themselves are expressed in many regions of the brain and e.g. regulate food intake and memory formation in humans and in animal models. In the animal model, disturbances in insulin signal transduction influence the development of pathologies typical of Alzheimer\u02bcs disease (AD). In humans, central insulin resistance is at least part of the formal pathogenesis of AD. Vascular changes (macroangiopathy) in patients with diabetes mellitus often lead to cerebral insults, microangiopathies and vascular\n          dementia.<\/jats:p>","DOI":"10.1055\/a-2009-9755","type":"journal-article","created":{"date-parts":[[2023,1,10]],"date-time":"2023-01-10T19:07:15Z","timestamp":1673377635000},"page":"130-135","source":"Crossref","is-referenced-by-count":5,"title":["The
