Excess weight can pose a threat for patients in later life. Apart from numerous studies about negative effects of obesity on cardiovascular system, there wasn't any prominent research on links between excess weight and the risk of brain decline. Recently, Korean scientists proved there was some stable relationship.


The study based on a sample of 250 people between 60 and 70 years old have found people with excess weight, or, rather, with a high body mass index scored poorly in a set of cognitive tests.


According to the Alzheimer's disease specialists see this research as a step forward in making important conclusions about obesity and brain function. Korean study was published in the journal Age and Ageing. Researchers came up with an hypothesis that excess weight can have an effect on brain functions.


Although it seems impossible to change old people life habits but, authors argue that this might help to reduce the risk of dementia connected with BMI (Body Mass Index).


A high body mass index along with a high level of abdominal fat both affected a cognitive skills of people between the age of 60 and 70. It is interesting to note that in individuals aged 70 and older with similar BMI and abdominal fat, mentioned before were not linked to the risk of dementia.


The authors argue that their findings are crucial and can infer public health. The struggling with obesity is an important society issue. From this prospective the results of the study add more sense in fighting excess weight in a bid to prevent a set of cognitive disorder in a particular age group.
