Yale Psychologist, Susan Nolen-Hoesksema died this month at 53 years-old. She provided insight into depression among women and theorized why there is a higher rate of depression among women versus men. She promoted the idea that rumination slows the recovery rate of depression and interferes with the ability to problem solve.
By knowing that rumination perpetuates the cycle of depression, we can more easily see how cognitive behavioral therapy (CBT) can help stop this cycle. CBT helps people to begin to think more rationally and adaptively which could then help them to move forward with problem solving. It is these changes that can then help to decrease depression.
