Stroke can be clinically recognized through a sudden or rapid onset of symptoms which reflect global or focal deficit of neurological function, lasting around 24 hours or yielding death. Due to infarction or hemorrhage of the central nervous system, it is classified as both a neurological disorder and vascular injury. There are associations between stroke development and hypertension, diabetes, history of smoking, and more. Despite the wide range of severity in symptoms, strokes are generally characterized by difficulties with motor function, visual deficits, speech and language deficits, pain, and other difficulties with daily life activities which yield a strong dependence on a caregiver or nursing facility. Combinations of pharmacological- and rehabilitation-based treatments are the most common strategies to help a patient improve their overall function.
