Depression linked to faster cognitive decline in older adults

  • A review of 34 studies confirms depression is linked to faster cognitive decline in older adults.

A review of 34 longitudinal studies, involving 71,244 older adults, has concluded that depression is associated with greater cognitive decline.

The study included people who presented with symptoms of depression as well as those that were diagnosed as clinically depressed, but excluded any who were diagnosed with dementia at the start of study.

Previous research has found that depression is associated with an increased dementia risk.

The researchers recommend that preventative measures such as exercising, practicing mindfulness, and undertaking recommended therapeutic treatments, such as Cognitive Behaviour Therapy, might help protect cognitive health.

While the review included some studies into anxiety, the numbers were insufficient to draw a conclusion.
