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 ...
Epidural hematoma is when bleeding occurs between the tough outer membrane covering the brain (dura mater) and the skull. [4] When this condition occurs in the spinal canal, it is known as a spinal epidural hematoma. [4] There may be loss of consciousness following a head injury, a brief regaining of consciousness, and then loss of ...
Epidural hemorrhage is bleeding between the dura mater and the skull. [4] It is commonly associated with damage to the middle meningeal artery, often resulting from a skull fracture. Subdural hemorrhage is bleeding between the dura mater and the arachnoid. [4] Intracerebral hemorrhage is bleeding within the brain tissue itself. [4]
In addition, some patients may develop "pseudoaneurysms" after trauma which can eventually burst and bleed, a factor which might account for the delay in loss of consciousness. [ 4 ] Because a patient may have a lucid interval, any significant head trauma is regarded as a medical emergency and receives emergency medical treatment even if the ...
Symptoms of a mild brain injury include headaches, confusions, tinnitus, fatigue, changes in sleep patterns, mood or behavior. Other symptoms include trouble with memory, concentration, attention or thinking. [3] Mental fatigue is a common debilitating experience and may not be linked by the patient to the original (minor) incident.
The outcome is frequently coma, with over 90% of patients with severe DAI never regaining consciousness. [9] Those who awaken from the coma often remain significantly impaired. [10] DAI can occur across the spectrum of traumatic brain injury (TBI) severity, wherein the burden of injury increases from mild to severe.
Traumatic subdural hematoma, a bleeding below the dura mater which may develop slowly; Traumatic extradural, or epidural hematoma, bleeding between the dura mater and the skull; Traumatic subarachnoid hemorrhage; Cerebral contusion, a bruise of the brain; Concussion, a loss of function due to trauma
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.
