What are the Causes of Alzheimer disease

The exact cause of Alzheimer’s disease remains unknown, but researchers suggest that it likely arises from a combination of genetic, lifestyle, and environmental factors that affect the brain over time.

Genetic Factors:
Specific genetic alterations associated with the disease are observed in less than 5 percent of cases. While most individuals with Alzheimer’s do not have a family history of the condition, the risk of developing it increases if a family member is affected.

Metal Ingestion:
Some theories propose that metals like zinc or aluminum may play a role in Alzheimer’s disease. However, there is insufficient evidence to support these claims. Therefore, experts do not recommend reducing zinc intake or avoiding items containing aluminum, such as cooking utensils or soda cans.

Despite the uncertainty surrounding its cause, the effects of Alzheimer’s disease on the brain are well-documented. This disorder leads to the degeneration and death of brain cells, resulting in a decrease in cell count and connectivity compared to a healthy brain. Additionally, there is a reduction in chemical messengers or neurotransmitters, particularly acetylcholine, which facilitates proper nerve cell communication in the brain. These factors likely contribute to a progressive decline in cognition, memory, and overall mental function.
