Internal bleeding in the head, also known as a brain hemorrhage, prevents oxygen from reaching the brain tissue, which can be life-threatening. It requires immediate medical attention.
Here's a more detailed breakdown of the effects:
-
Oxygen Deprivation: The primary consequence of internal bleeding in the head is the disruption of oxygen supply to the brain. Blood accumulating within the skull or brain tissue puts pressure on delicate brain cells. This pressure restricts blood flow, and since blood carries oxygen, affected areas of the brain are starved of this vital element.
-
Brain Damage: Without sufficient oxygen, brain cells begin to die. The extent of brain damage depends on the location and severity of the bleed. Damage can range from mild impairment to permanent disability or death.
-
Increased Intracranial Pressure (ICP): The skull is a fixed space. As blood accumulates, it increases pressure inside the skull (ICP). Elevated ICP can further restrict blood flow to the brain, exacerbating oxygen deprivation. It can also compress brain structures, leading to neurological dysfunction.
-
Neurological Impairment: Depending on the location of the bleed, various neurological functions can be affected. This can manifest as:
- Weakness or paralysis on one side of the body.
- Difficulty with speech or understanding language.
- Vision problems.
- Seizures.
- Changes in consciousness, ranging from confusion to coma.
- Severe headache.
- Nausea and vomiting.
-
Herniation: In severe cases, increased ICP can cause parts of the brain to be squeezed past rigid structures within the skull. This is called herniation and is a life-threatening emergency.
-
Risk of Stroke: Sometimes the bleeding leads to secondary problems, such as a stroke. The initial bleed and resulting pressure can damage blood vessels, leading to blockage or further hemorrhage.
Types of Brain Hemorrhages:
Bleeding can occur in different areas within and around the brain. Common types include:
- Subarachnoid Hemorrhage: Bleeding between the brain and the surrounding membrane (arachnoid space).
- Subdural Hematoma: Bleeding between the brain and the outer membrane (dura mater).
- Intracerebral Hemorrhage: Bleeding within the brain tissue itself.
- Epidural Hematoma: Bleeding between the skull and the dura mater.
Symptoms:
Symptoms can vary depending on the location and severity of the bleed. Any sudden onset of severe headache, neurological deficits, or altered consciousness should be evaluated immediately.
Emergency Action:
If you suspect someone is experiencing internal bleeding in the head, call emergency services (911 in the US) immediately. Time is critical to minimize brain damage and improve the chances of survival.
