Depression, anxiety linked to the onset of Alzheimer ‘s disease News

Depression is known to increase the risk for developing Alzheimer’s disease. However, a new study has found that depression and anxiety are linked to an earlier onset of Alzheimer’s disease (AD). According to the study, if people develop Alzheimer’s disease, those with depression may start experiencing symptoms of depression about two years earlier than those without depression. The study also suggested that people with anxiety who develop Alzheimer’s may start experiencing depressive symptoms about three years earlier than those without anxiety. The study will be presented at the 73rd Annual Meeting of the American Academy of Neurology held almost April 17 to 22, 2021. Researchers also found a linear decrease in age when symptoms first began to double with each additional psychiatric disorder diagnosis. People with only one disorder developed symptoms about 1.5 years before those without psychiatric disorders. Those with two psychiatric conditions developed symptoms 3.3 years earlier than those without conditions. And those with three or more psychiatric disorders developed symptoms 7.3 years earlier than those without such a condition.
