What are the symptoms of Posterior Circulation Syndrome (POCS)?
One of:
Cerebellar or brainstem syndrome
Loss of consciousness
Isolated Homonymous hemaniopia
What are the symptoms of lacunar syndrome? (LACS)
One of:
Unilateral weakness (and/or sensory deficit) of face and arm, arm and leg or all three?
Pure sensory stroke
Ataxic hemiparesis
What are the symptoms of Partial Anterior Circulation Syndrome (PACS)
Two of:
Unilateral weakness (and/or sensory deficit) of face, arm and leg
Homonymous hemaniopia
Higher cerebral dysfunction (dysphasia, visuospatial dysfunction)
What are the symptoms of total anterior circulation stroke (TACS)?
All three of:
Unilateral weakness (and/or sensory loss) of face, arm and leg.
Homonymous hemaniopia
Higher cerebral dysfunction (dysphasia, visuospatial disorder)
What is TIA?
Acute loss of focal cerebral or ocular function, with symptoms lasting less than 24 hours.
Thought to be due to an inadequate cerebral or ocular blood supply as a result of low blood flow, a thrombosis or other cause. More recent definitions have stipulated that in TIA there is no infarction of the brain tissue, and that the symptoms are ‘transient’ rather than stipulating a timescale. This is important, because if you diagnose stroke, it affects insurance and the way you counsel about prognosis. There is therefore some disagreement about the exact definition.
