Condition
Ischaemic Stroke
Intervention
Eligible patients who have provided consent will be randomly assigned to receive either dexamphetamine or placebo control. Dexamphetamine or placebo control will be administered orally twice a week with alternating 3 or 4 day separations. There will be a total of 10 doses covering a treatment period of 31 days. Further measurements of haemodynamics will be made 90 minutes after the first dose and immediately before, and 90 minutes after, the second dose. Measurements of the Barthel, Rankin and Scandinavian Neurological Stroke Scale (SNSS) will also be repeated 90 minutes after the second dose. Patients will remain as inpatients for the 7 days required. Xenon CT will be performed on selected patients (approx 8) to assess the dexamphetamine effect on cerebral perfusion before and 1 hour after the first administration.
