What exactly is chronic subdural hematoma?

Blood around brain. There are three layers of tissue that surround the brain, known collectively as the "meninges." the outermost layer is the dura mater, the middle layer the arachnoid mater, and the layer closest to the brain the pia mater. When veins that go between these layers rupture - often because of trauma - blood can start to pool between the dura mater and arachnoid mater causing a subdural hematoma.
Subdural hematoma. A chronic subdural hematoma typical occurs after a head injury but does not present with symptoms until days to weeks after the event. It is a collection of fluid that develops between a membrane over the brain called the dura and the brain itself. If symptomatic these often need to be drained.

Intracranial blood. A subdural hematoma is a blood clot that forms between the brain and the fibrous membrane covering the brain (subdural space). It is usually a result of trauma with the stretching and tearing of a vein in the subdural space as the brain deforms during an acceleration, deceleration situation.. Read more...
SDH. A subdural hematoma typically occurs from bridging cortical veins being torn causing blood to accumulate on the surface of the brain under the dural covering of the brain. Trauma is the most common cause. In the elderly, even relatively minor head trauma can cause a sdh. Surgery is often used to evacuate the hematoma. Read more...

What exactly is a subdural hematoma?

Bleed next to brain. Subdural hematoma is bleeding between the inner and middle layers of the tissues wrapping the brain. It can be secondary to trauma or occur spontaneously, especially in patients with significant brain atrophy. Depending on size and rate of growth they can often be managed conservatively, but sometimes require neurosurgical drainage. Read more...

Headache. Most patients with symptomatic subdural hematoma report headaches. Other symptoms are related to the location and size of the bleeding. Read more...
Not always. Close to 90% of pts with sdh's experience headaches, but in some cases, these are very nonspecific, and in older pts, may not occur at all. May be tough to diagnose early on, and may even seem like a stroke, but then sudden catastrophic herniation seemingly out of blue. So, if head injury, headache, nausea and vomiting, dizziness, and especially focal weakness, numbness, get examined. Read more...

How long will you have to stay in the hospital with a chronic subdural hematoma?

Depends . Depends on symptoms and age of person. Older with more weakness/confusion. If surgically drained on somebody doing well, they may spend anywhere from 1-7 days in the hospital. If they need more assistance, getting around/safety around house etc. Would take more time. Good question to ask the team helping you. Read more...

How long after a head injury does a chronic subdural hematoma typically present in terms of symptoms? Can it present up to 1 year later?

Unpredictable. Usually most of the time immediately in couple of hrs some times few few days , epidural takes more time , will have lucid interval , some times dormant for months , the reason head injury needs evaluation by trained physician and CT scans are required most of the time , clear instructions from ER at the time of discharge.

Is a chronic subdural hematoma detected by CT scan important or just a normal occurance in a 83 year old that hit head 3 days prior to scan?

Chronic > 3 days. "Chronic" means that the bleeding began a few wks after injury. Thus, it is less likely that the hit to the head 3 days prior to the head CT caused the "chronic" subdural hematoma (SDH). SDH and head trauma are risk factors for seizures and other conditions. The patient should be closely monitored and see a neurologist for evaluation. http://www.nlm.nih.gov/medlineplus/ency/article/000781.htm. Read more...
