Hemorrhage tends to occur suddenly and during activity, especially among persons with hypertension. Hemorrhage is the most common form of CVA in middle age. Thrombosis is the most common form of CVA. It tends to occur among older patients, often during rest. Thrombosis may be preceded by transient neurologic involvement referred to as transient ischemic attacks. Thrombosis often begins with an intermittent or gradual course. Dural sinus thrombosis occurs most commonly in childhood (3 to 5 years). The longitudinal and straight sinuses are most frequently involved. Among adults, thrombosis often complicates a debilitating disease, hydration, or prolonged labor and delivery. Dural sinus thrombosis may be associated with infection of the ears and paranasal sinuses. Signs of dural sinus thrombosis are edema of the forehead, distention of scalp veins, lower limb spasticity, seizures, and hemiplegia. Persistent convulsions and sudden loss of consciousness are common.
