The researchers found the overall trend of declining BMI was associated with a higher risk of developing dementia. However, after further exploration, they found a subgroup with a pattern of initial increasing BMI followed by declining BMI, both occurring within midlife, which appeared to be central to the declining BMI-dementia association

A significant global public health concern, dementia now affects 50 million individuals and is projected to reach more than 150 million cases by 2050. An ongoing global problem is obesity, which is typically assessed by body mass index (BMI). Previous research has revealed that obesity in middle age may raise the risk of dementia. However, it is still unknown if BMI and the risk of dementia are related.
Now, researchers from Boston University Chobanian & Avedisian School of Medicine and Chinese Academy of Medical Sciences & Peking Union Medical College, have found that different patterns of BMI changes over one`s life course may be an indicator of a person`s risk for dementia.
