Phase 2 Results N/A

Trial Description

In this study the investigators wish to explore the potential neuroprotective effects of acute oral supplementation of lycopene, a natural anti-oxidant derived from tomatoes, on cerebral vasospasm and autoregulation, and examine whether any improvements translate into a reduction of biochemical markers of vascular injury and inflammation a decrease in the prevalence of secondary strokes following subarachnoid haemorrhage.
