Prevalence clearly varies over time with an apparent peak 3–6 months after stroke and subsequent decline in prevalence at one-year reaches about to 50% of initial rates. Robinson and colleagues characterized the natural course of major depression after stroke with spontaneous remission typically 1 to 2 years after stroke.
Prevalence changes over time, reaching a high point around 3 to 6 months after stroke and then decreasing by half at one year. Robinson and colleagues examined the natural development of major depression following stroke, observing that remission typically occurs within 1 to 2 years post-stroke.
