You have the right system, and subdural haemorrhages do indeed cause strokes, but not in this case. However, it is always important to exclude a subdural haemorrhage as it is a very treatable cause of strokes.

A subdural haemorrhage usually, but not always, occurs after trauma, but the trauma may be very slight. The elderly, those prone to falls, and those on long-term anticoagulation treatment are especially at risk. The symptoms are of a slowly developing stroke, and may include flucutating consciousness, sleepiness, headache, unsteadiness, and intellectual and physical slowness.

Try again.
