Epidemiology
The most common forms of cerebrovascular disease are cerebral thrombosis (40% of cases) and cerebral embolism (30%), followed by cerebral hemorrhage (20%).
Cerebrovascular disease is primarily one of old age; the risk for developing it goes up significantly after 65. CVD tends to occur earlier than Alzheimer's Disease (which is rare before the age of 80). In some countries such as Japan, CVD is more common than AD. CVD occurs more rarely in younger people due to conditions such as syphilis that lead to artery damage and strokes.
