Key result
Post-stroke recovery outcomes remain highly variable, limiting reliable clinical prediction.
Clinical outcomes after stroke are highly variable, and reasons for these variations are often unexplained. Recovery after ischemic or hemorrhagic stroke begins immediately after acute onset, and many different levels of biological responses are involved. These responses differ in time and between different areas of the affected brain. Recovery after a cerebrovascular event may, therefore, vary from being rapid, without detectable remaining neurological deficits, to prolonged improvement, if any, over months or years. Outcome prediction is consequently difficult and unreliable and often depends on factors with unclear and limited impact.

Lindgren et al. (2016) conducted a review in Stroke. Clinical outcomes and recovery after stroke are highly variable, making outcome prediction difficult and unreliable.
