Subdural hematoma is a bleeding between the inner layer of the dura mater and the arachnoid mater of the meninges surrounding the brain. It usually results from tears in bridging veins that cross the subdural space. Risk factors include taking blood thinners, long-term alcohol abuse, dementia, and cerebrospinal fluid leaks.
About Subdural hematoma in brief
Subdural hematoma is a bleeding between the inner layer of the dura mater and the arachnoid mater of the meninges surrounding the brain. It usually results from tears in bridging veins that cross the subdural space. It is more common in patients on anticoagulants or antiplatelet medications, such as warfarin and aspirin, respectively. Risk factors include taking blood thinners, long-term alcohol abuse, dementia, and cerebrospinal fluid leaks. In juveniles, an arachNoid cyst is a risk factor for subdial hematomas. In these cases, blood usually accumulates between the two layers. This can cause ismicmic damage by two mechanisms: one, pressure on the cortical blood vessels, and two, vasoconstriction due to the release of substances from the hematomatoma. The latter can lead to brain cell death as a result of the pressure they place on the brain, resulting in furtherchemia by restricting the brain flow to the brain tissue.
In infants, too, have larger subDural spaces and are more predisposed to subdral bleeds than are young adults. It’s often claimed that subdurals hematomes are a common finding in shaken baby syndrome, although there is no science to support this. The symptoms of a subdoral hematome have a slower onset than those of epidural heMatomas because the lower-pressure veins involved bleed more slowly than arteries. If the bleeds are large enough to put pressure onThe brain, signs of increased intracranial pressure or brain damage will be present. Other symptoms can include any combination of the following: swelling, bruising, bleeding, or swelling in the head, face, neck, or back. If you are concerned about the prognosis, see your doctor for more information on how to treat a sub duralshematoma and how to get it under control.
