SUBDURAL HEMATOMA Meaning and
Definition
-
Subdural hematoma is a medical condition characterized by the accumulation of blood between the brain's surface and its protective outer covering, known as the dura mater. This condition occurs when blood vessels within the brain rupture or tear, causing bleeding or hematoma formation in this space. It is typically a result of a traumatic head injury, although spontaneous subdural hematomas can also occur due to conditions like bleeding disorders or the use of blood thinning medications.
The blood that accumulates in a subdural hematoma puts pressure on the brain tissue, disrupting its normal functioning. This pressure can cause various symptoms, which may include headache, confusion, dizziness, nausea, vomiting, seizures, weakness, numbness, difficulty speaking or understanding speech, and changes in vision. The severity of symptoms depends on the size and location of the hematoma.
Subdural hematomas are typically classified as acute, subacute, or chronic, depending on the time elapsed since the initial injury or bleeding. Acute hematomas occur within a few hours to a few days, subacute hematomas develop within a few days to weeks, and chronic hematomas may take weeks or months to manifest symptoms.
Prompt medical attention is necessary for the diagnosis and treatment of subdural hematomas. Treatment options may include surgery to drain the accumulated blood and relieve pressure on the brain. Rehabilitation therapies may also be necessary to address any neurological deficits caused by the hematoma. The prognosis for individuals with subdural hematomas varies depending on various factors such as the size of the hematoma, the time taken for treatment, and the overall health of the patient.

Etymology of SUBDURAL HEMATOMA
The word "subdural" originates from the Latin prefix "sub-" meaning "below" and the Latin word "dura" meaning "hard". In anatomy, the term "dura" refers to the tough outermost membrane that covers the brain and spinal cord.
The word "hematoma" comes from the Greek roots "haima" meaning "blood" and "toma" meaning "tumor" or "mass". Therefore, a hematoma is a localized collection or clot of blood outside the blood vessels.
Combining both parts, "subdural hematoma" refers to a clot of blood that forms below the dura mater, between the dura and the brain.
