Cerebrovascular events are the most common neurological complications seen in renal transplant recipients. Cerebral infarction and transient ischemic attacks are the most common events and may occur years after transplantation. Recipients older than 40 years at the time of transplantation and those with diabetes mellitus are at greater risk. No instances of aneurysmal subarachnoid hemorrhage occurred among 31 patients with polycystic kidney disease who had undergone transplantation.
