New studies highlighted in the Guardian reveal that those who are obese in middle age are at approximately four times greater risk of developing dementias, such as Alzheimer’s disease, later in life. The study, published in the journal, Neurology, examined data on over 8,500 persons above age 65. Of the sample, 350 had been diagnosed with Alzheimer's disease or vascular dementia with 114 having possible dementia. Scientists used records of the participants' height and weight in the subjects’ previous decades and found that those who had been overweight in middle age had an 80% greater risk of suffering from dementia later in life. The study also revealed that those who spent a lifetime struggling with obesity had an eye-opening 300% greater risk of developing dementia. Exactly how excess weight can influence the degradation of the brain is not certain, but higher body fat is associated with diabetes and vascular diseases, both of which are related to dementia risk. In addition, fatty tissue is the largest hormone-producing organ in the body and can produce inflammatory molecules which may affect cognitive functioning or the process of neuro-degeneration.
