Depression changes the brain

Depression changes the brain

New brain imaging research from the Centre for Addiction and Mental Health (CAMH) shows that the brain alters after years of persistent depression, suggesting the need to change how we think about depression as it progresses.

This study provides the first biological evidence for large brain changes in long-lasting depression, suggesting that it is a different stage of illness that needs different therapeutics – the same perspective taken for early and later stages of Alzheimer’s disease, he says.

“Greater inflammation in the brain is a common response with degenerative brain diseases as they progress, such as with Alzheimer’s disease and Parkinson´s disease,” says Dr. Meyer, who also holds Canada Research Chair in the Neurochemistry of Major Depression. While depression is not considered a degenerative brain disease, the change in inflammation shows that, for those in whom depression persists, it may be progressive and not a static condition.
