Excessive weight loss is prone to dementia
Experts at BV Massachusetts have detected the connection between body weight index with the accumulation of amyloid patches in the brain, triggering brain-destructive disorders.
Researchers have even said that people with age should gain weight, should not overeat because if the body is too lean will lead to Alzheimer's dementia disease.
Studies have also found that the cause of Alzheimer's is associated with weight-strengthening hypotheses for that too lean when age is not good for the brain. This may be because the low BMI is a sign of weakness. Excessive weight loss when the age leads to delayed activity and loss of health to fight disease, maintain the normal functioning of the body.

This study was part of Harvard's plan for brain aging to identify the causes and symptoms of Alzheimer's disease. Researchers have looked at 280 people aged 62-90, all in good health. After excluding other causes such as age, physiological, educational, they pay attention to the BMI and brain scans to determine the level of amyloid in the brain.
The group with a low BMI has the highest presence of a gene called APOE4, which is the main factor causing the risk of Alzheimer's.

Scientists hope that later studies will explain the relationship between the BMI and the level of amyloid. They will continue to monitor the volatility of the BMI and the brain over time, see if weight gain can help make the result change.
