Midlife Anxiety Tied to Late-Life Dementia
Moderate to severe midlife anxiety may be an independent risk factor for late-life dementia, new research shows. Investigators reviewed the findings of four studies, encompassing almost 30,000 people. Individuals with midlife anxiety disorders or serious anxiety symptoms were significantly more likely to develop dementia in later life, on average at least a decade prior to their being diagnosed with dementia. These findings excluded anxiety related to prodromal cognitive decline.
@shreyashi Some research suggests that a long interval between the diagnosis of depression and the diagnosis of dementia suggests that depression is a risk factor rather than merely a prodromal symptom of dementia, they note. The role of anxiety as a potential risk factor has been less studied than that of depression, although anxiety symptoms have been found to be commonly experienced in the years preceding a dementia diagnosis and have been associated with cognitive decline.
