🔗 Type 3 Diabetes (Alzheimer's)
Type 3 diabetes is a proposed term to describe the interlinked association between type 1 and type 2 diabetes, and Alzheimer's disease. This term is used to look into potential triggers of Alzheimer's disease in people with diabetes.
The proposed progression from diabetes to Alzheimer's disease is inadequately understood; however there are a number of hypotheses describing potential links between the two diseases. The internal mechanism of Insulin resistance and other metabolic risk factors such as hyperglycaemia, caused by oxidative stress and lipid peroxidation are common processes thought to be contributors to the development of Alzheimer's disease in diabetics.
Diagnosis for this disease is different between patients with type 1 and type 2 diabetes. Type 1 diabetes is usually discovered in children and adolescence while type 2 diabetic patients are often diagnosed later in life. While Type 3 diabetes is not a diagnosis in itself, a diagnosis of suspected Alzheimer's disease can be established through observational signs and sometimes with neuroimaging techniques such as Magnetic Resonance Imaging (MRI) to observe abnormalities in diabetic patient's brain tissue.
The techniques used to prevent the disease in patients with diabetes are similar to individuals who do not show signs of the disease. The four pillars of Alzheimer's disease prevention is currently used as a guide for individuals of whom are at risk of developing Alzheimer's disease.
Research into the effectiveness of Glucagon-like Peptide 1 and Melatonin administration to manage the progression of Alzheimer's disease in diabetic patients is currently being conducted to decrease the rate at which Alzheimer's disease progresses.
Labelling Alzheimer's disease as Type 3 Diabetes is generally controversial, and this definition is not a known medical diagnosis. While insulin resistance is a risk factor for the development of Alzheimer's disease and some other dementias, causes of Alzheimer's disease are likely to be much more complex than being explained by insulin factors on their own, and indeed several patients with Alzheimer's disease have normal insulin metabolism.
