Medicine & Surgery Neurology Corticospinal (pyramidal) system Enables purposive, skilled, intricate, strong and organised movements

Extrapyramidal system

Basal ganglia motor systems Fast, fluid movements that the corticospinal has generated Examples: Parkinson's, Huntington's, Hemiballismus

Cerebellum Coordinates smooth and learned movements initiated by the pyramidal system and in posture and balance Disease leads to unsteady, jerky movements (ataxia)

Stroke & Cerebrovascular Disease 2nd most common cause of death ~9%
Risk factors HTN Smoking DM Heart disease Previous stroke Carotid bruit The pill Hyperlipidaemia Alcoholism Increased clotting

Transient Ischaemic Attacks Sudden loss of function for <24hours Hemiparesis and aphasia are most common


Amaurosis fugax o Sudden loss of vision in one eye o Emboli in the retinal arteries o Evidence of internal carotid artery stenosis


Transient global amnesia o Epispodes of amnesia, lasting several hours o Posterior circulation ischaemia

Cerebral Infarct Occlusion  ischemia  infarction Infarction becomes swollen and does not function Commonly: thromboembolism in a middle cerebral artery branch  infarction of the internal capsule
