A subdural hematoma can develop within hours to weeks after a head trauma, but it commonly occurs within the first 24 to 48 hours after the injury. It is important to monitor for symptoms of a subdural hematoma like headaches, confusion, and neurological deficits in the days following a head injury.

What is the difference between a stroke and a subdural hematoma?
A stroke occurs when blood flow to the brain is disrupted, leading to cell death. A subdural hematoma, on the other hand, is a collection of blood between the brain and its outermost covering (the dura mater), often caused by head trauma. Both can lead to neurological symptoms, but a stroke is due to a blood vessel blockage or rupture in the brain, while a subdural hematoma is blood collecting outside the brain tissue.
What is the difference between a intracerebral hematoma and subdural hematoma?
An intracerebral hematoma occurs when there is bleeding inside the brain tissue itself, often due to trauma or a ruptured blood vessel. A subdural hematoma, on the other hand, is bleeding that occurs between the brain and the dura (the tough outer membrane covering the brain), usually as a result of head injury or brain atrophy. The location of the bleeding is the main difference between the two.
Can severe head trauma cause you to be less intelligent?
Severe head trauma can result in cognitive impairments such as memory loss, difficulty concentrating, and reduced problem-solving abilities, which may affect overall intelligence levels. However, intelligence is a complex trait influenced by multiple factors, and the impact of head trauma can vary from person to person. Rehabilitation and cognitive therapy may help mitigate some effects of head trauma on intelligence.
Can trauma cause an infarct in the brain?
Yes. Infarction is a state of tissue death due to no blood supply to that area. A trauma to any area of the body can cause the obstruction of blood flow to that area, hence causing an infarction. Though the brain is heavily protected, brain infarction can occur.
What are some common problems between serial killers?
Some common problems between serial killers include a lack of empathy or remorse for their victims, a desire for power and control, and often a history of childhood trauma or abuse. Additionally, many serial killers exhibit patterns of manipulation and deceit in their relationships and interactions.
Why does a headache develop with a subdural hemorrhage?
i think its because the blodd that is coming out compresses the brain with the skull which then causes the headache

How serious is a subdural hematoma?
Symptoms appearing in less than 48 hours are due to an acute subdural hematoma. This type of bleeding is often fatal, and results from tearing of the venous sinus.
Is a subdural hemorrhage a terminal disease?
A subdural hematoma (hemorrhage) is usually the result of a serious head injury. When it occurs this way it's called an "acute" subdural hematoma. Acute subdural hematomas are among the deadliest of all head injuries. The blood fills the brain area very rapidly and compresses the brain tissue. This often results in brain tissue injury or infarction and many times even death. In the elderly, subdural hematomas can also be a result of a slight knock to the head or falls.
What is the difference between a intracerebral hematoma and subdural hematoma?
An intracerebral hematoma occurs when there is bleeding inside the brain tissue itself, often due to trauma or a ruptured blood vessel. A subdural hematoma, on the other hand, is bleeding that occurs between the brain and the dura (the tough outer membrane covering the brain), usually as a result of head injury or brain atrophy. The location of the bleeding is the main difference between the two.
How can shaking a baby lead to subdural hematoma?
Shaken Baby Syndrome is a condition caused by violently shaking a baby. There are usually three signs in a baby that shaking may have occurred: subdural hematoma, retinal hemorrhage, and cerebral edema. Subdural hematoma (bleeding in the brain) is caused by the brain "bouncing around" inside the skull. As the head is whipped back and forth (the same sort of injury that can occur with whiplash), the brain is forcefully slammed into the dura and impacted against the inner wall of the skull, causing bleeding and swelling beneath the dura, or between the dura and the brain tissue. This trauma also causes brain swelling (cerebral edema), and through an action known as "vitreoretinal traction", the distinctive pattern of retinal hemorrhaging can occur.
Is subdural hematoma a malignant tumor?
No, a subdural hematoma is not a malignant tumor. It is a collection of blood that occurs between the inner layer of the dura mater (a protective membrane covering the brain) and the surface of the brain. Subdural hematomas can be caused by traumatic injuries to the head or by underlying medical conditions such as bleeding disorders. They can be life-threatening if left untreated and require prompt medical attention.
Compare epidural hematoma and subdural hematoma?
Your skull is like a Box. You can only "fit" so much into it. When you introduce blood due to an injury (trauma), the blood has no where to go so this causes pressure on the brain and eventually you DIE! Your brain is covered with various tissue to protect and nourish it. In addition to the skull you have the dura matter (tough mother), arachnoid process (vascular) and the Pia matter which surrounds the brain. Trauma or striking the skull (falling down hitting your head, baseball bat, bullet) can cause injury to the tissues of the brain.The epidural hematoma involves an artery (usually the meningeal artery) and can occur in numerous places. This is a fast bleed and you can expire fast. The subdural is a venous bleed (slower) but can have the same devastating effects. In both cases neurosurgery is the only option, but in most cases by that time your chances for survival (morbidity) are small.
What is the most dangerous thing to do for patient with head injury and nonreactive pupils?
This can indicate the patient has a subdural hematoma or bleeding in the brain. They need emergency surgery to fix it. The most dangerous thing is to waste time and moving the head too suddenly or violently.

Subdural hematoma?
DefinitionA subdural hematoma is a collection of blood on the surface of the brain.Alternative NamesSubdural hemorrhageCauses, incidence, and risk factorsSubdural hematomas are usually the result of a serious head injury. When one occurs in this way, it is called an "acute" subdural hematoma. Acute subdural hematomas are among the deadliest of all head injuries. The bleeding fills the brain area very rapidly, compressing brain tissue. This often results in brain injury.Subdural hematomas can also occur after a very minor head injury, especially in the elderly. These may go unnoticed for many days to weeks, and are called "chronic" subdural hematomas. With any subdural hematoma, tiny veins between the surface of the brain and its outer covering (the dura) stretch and tear, allowing blood to collect. In the elderly, the veins are often already stretched because of brain atrophy (shrinkage) and are more easily injured.Some subdural hematomas occur without cause (spontaneously).The following increase your risk for a subdural hematoma:Anticoagulant medication (blood thinners, including aspirin)Long-term abuse of alcoholRecurrent fallsRepeated head injuryVery young or very old ageSymptomsConfused speechDifficulty with balance or walkingHeadacheLethargy or confusionLoss of consciousnessNausea and vomitingNumbnessSeizuresSlurred speechVisual disturbancesWeaknessIn infants:Bulging fontanelles (the "soft spots" of the baby's skull)Feeding difficultiesFocal seizuresGeneralized tonic-clonic seizureHigh-pitched cryIncreased head circumferenceIncreased sleepiness or lethargyIrritabilityPersistent vomitingSeparated sutures (the areas where growing skull bones join)Signs and testsAlways get medical help after a head injury. Older persons should receive medical care if they shows signs of memory problems or mental decline. An exam should include a complete neurologic exam.Your doctor may order a brain imaging study if you have any of the following symptoms:Confused speechDifficulty with balance or walkingHeadacheInability to speakLethargy or confusionLoss of consciousnessNausea and vomitingNumbnessRecent congitive decline in an elderly person, even without a history of brain injurySeizuresSlurred speechVisual disturbanceWeaknessA CT scan or MRI scan likely would be done to evaluate for the presence of a subdural hematoma.TreatmentA subdural hematoma is an emergency condition.Emergency surgery may be needed to reduce pressure within the brain. This may involve drilling a small hole in the skull, which allows blood to drain and relieves pressure on the brain. Large hematomas or solid blood clots may need to be removed through a procedure called a craniotomy, which creates a larger opening in the skull.Medicines used to treat a subdural hematoma depend on the type of subdural hematoma, the severity of symptoms, and how much brain damage has occurred. Diuretics and corticosteroids may be used to reduce swelling. Anticonvulsion medications, such as phenytoin, may be used to control or prevent seizures.Expectations (prognosis)The outlook following a subdural hematoma varies widely depending on the type and location of head injury, the size of the blood collection, and how quickly treatment is obtained.Acute subdural hematomas present the greatest challenge, with high rates of death and injury. Subacute and chronic subdural hematomas have better outcomes in most cases, with symptoms often going away after the blood collection is drained. A period of rehabilitation is sometimes needed to assist the person back to his or her usual level of functioning.There is a high frequency of seizures following a subdural hematoma, even after drainage, but these are usually well controlled with medication. Seizures may occur at the time the hematoma forms, or up to months or years afterward.ComplicationsBrain herniation (pressure on the brain severe enough to cause coma and death)Persistent symptoms such as memory loss, dizziness, headache, anxiety, and difficulty concentratingSeizuresTemporary or permanent weakness, numbness, difficulty speakingCalling your health care providerA subdural hematoma requires emergency medical attention. Call 911 or your local emergency number, or go immediately to an emergency room after a head injury.Spinal injuries often occur with head injuries, so try to keep the person's neck still if you must move him or her before help arrives.PreventionAlways use safety equipment at work and play to reduce your risk of a head injury. For example, use hard hats, bicycle or motorcycle helmets, and seat belts. Older individuals should be particularly careful to avoid falls.ReferencesHeegaard WG, Biros MH. Head. In: Marx JA, ed.
