Can Alzheimer's disease be passed down through generations?
Alzheimer's follows an autosomal dominant inheritance which means that an individual has a greater risk of developing the disease if an immediate family member has the condition. In this pattern of inheritance, there is a 50% chance of developing the disease if one of the parents has it. Therefore, a doctor should be informed of such a family history.

Yes, Alzheimer’s disease is hereditary, which makes it important for you to know your family history. A child can inherit Alzheimer’s disease from their parent. Therefore, you must share your family history with the doctor to receive immediate treatment.

Your chances of developing this disease increase if an immediate family member has Alzheimer’s disease or dementia. Immediate family may include one of the parents or a first-degree relative. There is a 50% chance that a copy of an altered gene will pass to a child through an autosomal dominant pattern. Some genes that tend to cause Alzheimer’s disease are apolipoprotein E (APOE), amyloid precursor protein (APP), presenilin 1 (PSEN1), and presenilin 2 (PSEN2). Moreover, diabetes also increases the risk of dementia because of changes in the blood protein called haemoglobin A1C (HbA1C).

Autosomal dominant inheritance explains the mechanism behind a disorder that passes from one generation to another. If there is a diagnosis of a genetic disorder in a family, the members would want to know if it will pass on to their children. Researchers are trying to find the genetic basis of Alzheimer’s disease. This is because it is difficult to confirm the inheritance of a genetic disorder by the next generation at present. However, the autosomal dominant pattern provides a 50% chance of children inheriting the disorder. In this pattern of inheritance, mutation occurs in the non-sex genes. Even a single copy is enough to cause the disease. This makes Alzheimer’s disease a difficult condition to handle. This is especially because a parent with one affected gene is enough to risk the next generations.
