What is a stroke?
Sudden onset of focal neurological deficit attributable to a vascular cause
Describe a stroke classification system
Bamford/Oxford Stroke Classification
TACS = all three of: unilateral weakness (+/- sensory deficit) of face, arm and leg + homonymous hemianopia + higher cortical dysfunction (dysplasia, visuospatial disorder)
PACS = two out of: unilateral weakness (+/-sensory deficit) of face, arm and leg + homonymous hemianopia + higher cerebral dysfunction
POCS = one of: cranial nerve palsy and contralateral motor/sensory deficit + bilateral motor/sensory deficit + conjugate eye movement disorder + cerebellar dysfunction + isolated homonymous hemianopia
LACS = one of: pure sensory stroke + pure motor stroke + sensori-motor stroke + ataxic hemiparesis
State the most likely cause of each different type of stroke
TACS = cardiac emboli - affects areas of brain supplies by both ACA + MCA PACS = large vessel disease - only part of anterior circulation is compromised POCS = cerebellar/brainstem - posterior circulation is compromised LACS = small vessel disease - no loss of higher cerebral functions
Describe the blood supply of the brain
ACA - anteromedial cerebrum (frontal, medial)
MCA - lateral cerebrum (frontal, lateral, parietal, temporal)
PCA - medial and lateral posterior cerebrum (occipital)
Describe the acute assessment of a stroke
Ix - CT head, clotting, U&Es, cholesterol
Mx - O2 if sats <94%, thrombosis, HTN management
State the management of a stroke that presents in <4.5h
Thrombolysis with alteplase
Aspirin 300mg
Describe the management of an acute stroke
Aspirin 300mg OD for 14 days Clopidogral 75mg Consider thrombolysis Maintain BP <130/80 Statin Transfer to stroke unit Advice smoking cessation
List complications of stroke
Seizures Stroke extension Disability +incontinence Recurrence Depression Cognitive decline Infections
Define the ABCD2 score and what is it used for
= to determine the risk of stroke in the days following a TIA Age >60: <60 = 0 >60 = 1 BP >140/90 <140/90 = 0 >140/90 = 1 Clinical features: No speech disturbance or unilateral weakness = 0 Speech disturbance with no unilateral weakness = 1 Unilateral weakness = 2 Duration of symptoms <10 mins = 0 10-59 mins = 1 >60 mins = 2 Diabetes No diabetes = 0 Diabetes = 1 0-3 = low, 4-5 = moderate, 6-7 = high

Describe the pathophysiology of Parkinson’s Disease
Low dopamine in substantia nigra in the basal ganglia (controls movement)
What is Parkinson’s Disease?
A degenerate, progressive disease affecting the basal ganglia
List the clinical features of Parkinson’s
Motor features:
