HEADACHES
Headaches can be divided into secondary headache (defined pathophysiological basis) or primary headache (uncertain
pathogenesis; generally more benign, migraine and tension-type headaches, primary headaches more common. Headache
o=en accompanies stroke, esp. when caused by haemorrhage, intracranial venous sinus thrombosis or arterial dissec@on.
Metabolic disturbances e.g. hypoxia, hypercapnia and hypoglycaemia, can trigger headache, as can vasoac@ve drugs and
other substances (E.g. alcohol, monosodium glutamate, nitrites, nitrates).
