Stroke is a clinical diagnosis where an acute neurological deficit follows a cerebrovascular insult.
There are two main groups of stroke: ischaemic (80%) or haemorrhagic (20%).
Epidemiology
Stroke is an extremely common condition - it is the leading cause of disability and the second cause of morbidity.
Vascular risk factors are shared in ischaemic stroke (age, male gender, family history, hypertension, smoking, hyperlipidaemia, diabetes). Hypertension is also a primary risk factor in haemorrhagic strokes.
Clinical presentation
Stroke is a sudden neurological deficit. The symptoms that manifest depend on the vascular territories involved. In any patients with acute neurological changes (motor, sensory, speech, vision, consciousness, behaviour) a stroke should be considered.
Time of onset is important when considering treatment options. There can be fluctuance in symptoms over time.
Pathology
Radiographic features
