The mortality rate is higher than that of epidural hematomas and diffuse brain injuries because the force required to cause subdural hematomas tends to cause other severe injuries as well. [24] Chronic subdural bleeds develop over a period of days to weeks, often after minor head trauma, though a cause is not identifiable in 50% of patients. [11]

Subdural hematoma maybe less acute than epidural hematoma due to slower blood accumulation, but it still has the potential to cause brain herniation that may require surgical evacuation. [3] Clinical features depend on the site of injury and severity of injury. Patients may have a history of loss of consciousness but they recover and do not ...
The cause of IVH in premature infants, unlike that in older infants, children or adults, is rarely due to trauma. Instead it is thought to result from changes in perfusion of the delicate cellular structures that are present in the growing brain, augmented by the immaturity of the cerebral circulatory system, which is especially vulnerable to ...
intracranial hematoma – a condition in which a blood vessel ruptures causing a pool of blood to form around the brain (subdural hematoma) or between the brain and the skull (epidural hematoma). Intracranial hematoma causes an increase in pressure on the brain and requires immediate medical attention. [5]
Most subdural hygromas are believed to be derived from chronic subdural hematomas. They are commonly seen in elderly people after minor trauma but can also be seen in children following infection or trauma. One of the common causes of subdural hygroma is a sudden decrease in pressure as a result of placing a ventricular shunt.
Brazilian President Luiz Inacio Lula da Silva underwent a craniotomy in Sao Paulo to drain a subdural hematoma linked to a fall at home on Oct. 19, according to a medical note published by the ...
Cerebral amyloid angiopathy may cause intraparenchymal hemorrhage even in patients without elevated blood pressure. Unlike hypertension, cerebral amyloid angiopathy does not typically affect blood vessels to deep brain structures. Instead, it is most commonly associated with hemorrhage of small vessels in the cerebral cortex. [2]
