Gradual weight reduction that begins in middle age and lasts until old age may be a sign of increased risk for dementia
Reducing body weight is not necessarily a good thing, because if it happens continually from middle age may be a clear indicator of increased risk for developing dementia.
According to the new results, reducing weight by 5 pounds during 10 years is associated with an average 24% higher risk for problems with memory that precede dementia.
In these patients is observed higher risk for type 2 diabetes, high blood pressure, heart disease and stroke.
The study used data on about 1,900 respondents aged over 70 years.
Professional journal JAMA Neurology says that such an unplanned weight loss may be due to previously unidentified factors associated with the risk for dementia.
