Don't be confused between the underlying cause and the resulting signs and symptoms. The left-sided hemiplegia of this patient was as a result of a TIA (transient ischaemic attack). By definition, the symptoms of a TIA last less than 24 hours, as the blockage in the artery clears. They are a dangerous pointer to future strokes - preventative treatment should be undertaken after the first TIA. This includes lifestyle changes, and reducing the risk factors for myocardial infarctions and strokes. A half tablet of aspirin each day may also be of value.
