* Vascular pathology if the CNS is less common in animals than in humans.
* Pathologies include:
** Thrombosis
** Infarction
** Haemorrhage
* These can occur:
** Spontaneously
** Secondary to drug therapy
** E.g. L-asparaginase or anti-coagulants.
** With thrombocytopaenia or other bleeding disorders
** With trauma
** With hypertension
** With atherosclerosis from hypothyroidism
** With infection
*** I.e. septic emboli.
* MRI and CT may detect haemorrhage and infaction.
==Hypertension Related Brain Haemorrhage==
* Not uncommon in geriatric cats.
** Hypertension is defined as a systolic pressure greater than 175mmHg.
* The systemic hypertension may be:
** Primary
** Secondary to:
*** Hyperthyroidism
*** Chronic renal failure
*** [[DM|Diabetes mellitus]]
*** Acromegaly
*** Chronic severe anaemia
*** Hyperadrenocorticism
*** Hyperaldosternism
*** Phaeochromocytoma.
* For this reason, cats presenting with forebrain disease should first have their blood pressure checked.
** If raised, this should be treated before further investigation takes place.
