It is a collection of blood inside the skull and outside the brain. Since the skull is in- expandable, this collection of blood compresses the brain and results in various symptoms like severe headache, dizziness, weakness on one side of the body, feeling of nausea and vomiting, imbalance while walking, seizures, drowsiness, difficulty in speech, changes in vision and lack of mental clarity. The severity of symptoms varies depending upon the location and size of the SDH and the patient’s health before the injury.


SDH’S is most commonly caused by sudden impacts resulting in a head shaking. This sudden shaking results in the shifting of the brain within the skull, causing small blood vessels to tear that bridge between the skull and brain. Based on the size and location of torn blood vessels, bleeding can be brisk or slow resulting in immediate symptoms or many days after the injury.

People with an underlying medical history of clotting disorders or on aspirin or anticoagulation therapy may develop spontaneous bleeding without obvious trauma. Old age people are more prone to develop SDH, owing to frequent falls and associated medical history. Patients with previous intracranial shunt procedures are also prone to it.


Small subdural haematomas do not require any treatment, but the patient need to be observed and monitored with repeated scans to observe the size of haematoma and its trend. Larger haematomas compressing brain needs urgent attention and surgical removal.
