Stroke

Dr Tee Yu Jin and A.Prof Frank Gaillard et al.

Stroke is a clinical diagnosis that refers to a sudden onset focal neurological deficit of presumed vascular origin.

It is divided into two broad categories:

  1. ischemic stroke  (80% 2)
  2. hemorrhagic stroke (15%)

Hemorrhage may be due to hypertension or other secondary causes such as vascular malformations.

Other causes of stroke-like symptoms include subarachnoid hemorrhage and tumors (via intratumoral hemorrhage or secondary seizures).
