There is a relationship between elderly patients with acute depression and progression to Alzheimer’s disease. It is unclear whether depression in the elderly is a risk factor for dementia or if it’s a prodrome of the disorder. It’s important to note if the late-life depression has documented memory and executive function impairment.
If depression is affecting you, or a loved one, please seek assessment and treatment. If the decline is due to cerebrovascular disease there may be an entirely different pathway to follow. Either way, ongoing follow-up and support are suggested.
