Symptoms vary depending on the extent of damage and the location of the bleeding. Symptoms most commonly develop suddenly, without warning, often during activity.
They may occasionally develop in a stepwise, episodic manner or in a progressive manner. There is a rapid loss of function(s) on one side of the body. These symptoms can be the same as when there is insufficient circulation to the brain (stroke).
Neurologic examination may indicate increased intracerebral pressure, such as swelling of the optic nerve or changes in eye movement. Localized abnormalities in brain function are detected by observing abnormal reflexes or movement.
