The Acute Subdural Hematoma Symptoms Explained
The Acute Subdural Hematoma Symptoms Explained An acute subdural hematoma (ASDH) is a serious brain injury that results from bleeding beneath the dura mater, the outer protective covering of the brain. This condition is typically caused by traumatic impacts such as falls, car accidents, or violent assaults that cause blood vessels to rupture, allowing blood to accumulate rapidly in the space between the dura and the brain. Recognizing the symptoms of an acute subdural hematoma promptly is crucial, as delays in diagnosis and treatment can lead to severe brain damage or death.
The Acute Subdural Hematoma Symptoms Explained The onset of symptoms can vary depending on the severity of the bleeding and the speed at which the blood accumulates. Often, symptoms develop suddenly and progress quickly, reflecting the rapid pressure increase within the skull. One of the earliest signs is a sudden change in consciousness. This can range from brief confusion or drowsiness to a deep coma, especially if the bleeding is extensive. In some cases, individuals may initially appear alert but then quickly deteriorate.
Headache is a common symptom associated with an acute subdural hematoma. The headache is often described as severe and persistent, and it may worsen over time. Alongside headache, patients frequently experience neurological deficits such as weakness or numbness on one side of the body, difficulty speaking, or visual disturbances. These deficits often correspond to the area of the brain affected by the bleeding. The Acute Subdural Hematoma Symptoms Explained
Altered mental status is another hallmark symptom. This can manifest as disorientation, agitation, or lethargy. In severe cases, the individual may exhibit signs of increased intracranial pressure, such as projectile vomiting, which is a forceful vomiting not related to nausea, and papilled
ema, which is swelling of the optic disc observed during eye examination. The clinical picture may also include seizures, which occur as abnormal electrical activity in the brain triggered by the bleeding and swelling.
As the pressure inside the skull continues to rise, the symptoms can become more severe and unpredictable. Pupillary changes are common; pupils may become dilated or unequal, indicating pressure on the cranial nerves. In some cases, a “blown pupil” on one side indicates herniation, where brain tissue shifts due to increased pressure, a life-threatening complication requiring immediate intervention.

In addition to these neurological signs, systemic symptoms such as dizziness, nausea, and vomiting are often present. The severity and combination of symptoms depend on the size of the hematoma and the speed of its development. Early recognition of these symptoms is essential for seeking urgent medical care, as treatment often involves surgical intervention to remove the blood clot and relieve pressure.

The Acute Subdural Hematoma Symptoms Explained In summary, symptoms of an acute subdural hematoma include sudden changes in consciousness, severe headache, neurological deficits, signs of increased intracranial pressure, and seizures. Recognizing these signs early can significantly improve outcomes, emphasizing the importance of prompt medical evaluation after head trauma.
