Chronic Subdural Hematoma
A chronic subdural hematoma is a buildup of blood
between the brain and the membrane that covers it, known as the
dura. This condition occurs as a result of a
and develops slowly over time. The trauma does not have to be
serious to produce this condition.
What is going on in the body?
A chronic subdural hematoma begins when a vein
ruptures. This causes slow bleeding into the space between the
dura and the brain. Over time, the hematoma can enlarge. This
puts pressure on the brain and produces mild to severe symptoms.
What are the causes and risks of the condition?
A chronic subdural hematoma is often caused by a
direct blow to the head, such as hitting the head on a rock. It
can also occur as a result of an indirect blow, such as when an
infant is shaken violently. This causes shaken baby syndrome.
During an indirect blow, the brain moves forcefully back and forth,
hitting the inside of the skull.
Risk factors for chronic subdural hematoma include:
being elderly, a group at high risk for falls
chronic conditions such as diabetes,
