Chronic subdural hematoma: clinical data and prognosis factors

The most common clinical signs for chronic subdural hematoma in adults are: motor weakness, increased intracranial pressure, confusion and loss of con sciousness. This pathology is more frequent in the elderly over 65 years, t he diagnosis also being more difficult in this case. Some misleading clinic al presentations may delay the decision to perform a CT scan to assess the diagnosis. Preoperative headaches and isodensity in CT-scan are features of good prognosis. Chronic alcoholism and postoperative pneumocephalus are re lated with poor prognosis.
