This is an extract of our Neurology document, which we sell as part of our Medicine and Surgery Notes collection written by the top tier of Bristol University students.
The following is a more accessble plain text extract of the PDF sample above, taken from our Medicine and Surgery Notes. Due to the challenges of extracting text from PDFs, it will have odd formatting:
Medicine & Surgery Neurology Corticospinal (pyramidal) system Enables purposive, skilled, intricate, strong and organised movements
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
