What is Chronic Subdural Hematoma?
In such a case, a preceding injury to the skull would have taken place but is forgotten. Nearly 25% of patients fail to give any history of head injury.
The causative injury may be trivial e.g. striking the head against the branch of a tree, a sudden stop in a car with lurching forward, striking the head during a fall or against a doorway.
This is followed by a period of weeks or even months without any complaint till such time headaches appear, thinking becomes slow, confusion begins, changes in personality, seizures or a mild half body paresis. Memory begins to fail. Management is surgical.
