Obesity is harmful for the brain

November 23, 2005

Researchers of a Swedish university have found out that obesity is harmful to the brain for women, but it does not pose the risk of dying for men who have suffered heart attacks. The study suggests that women who have been obese throughout their lives are more likely to lose brain tissue in the temporal lobe as compared with women of normal weight.

Loss of brain tissue has been directly linked to cognitive decline and it can increase the risk of Alzheimer's disease. Apart from these, obesity is a known cause of heart disease. The study was first to show that a higher body mass index is related to brain atrophy. A significant relationship between body mass index (BMI) and brain atrophy was found in the temporal lobe and the temporal lobe is very important for a number of reasons, including hearing, speech, language, comprehension, naming, memory, and visual processing. Therefore obesity can result in some serious implications which can prove fatal to our lives.
