Subdural Haematoma

A subdural haematoma is a collection of blood that forms between the brain's surface and its outermost protective covering, typically resulting from the tearing of small bridging veins after head trauma. It can develop rapidly following a severe head injury, known as an acute subdural haematoma, or slowly over days to weeks after a relatively minor injury, particularly in older adults, known as a chronic subdural haematoma. As the blood collection enlarges, it can compress the underlying brain tissue, leading to progressively worsening neurological symptoms. Prompt recognition is critical since some cases can rapidly become life-threatening.

The most common symptoms include: Headache; confusion or altered mental status; drowsiness or difficulty staying awake; weakness on one side of the body. Early recognition is key to prompt diagnosis and effective treatment.

No, Subdural Haematoma is not contagious. It cannot spread through casual contact. However, certain risk factors and genetic predispositions may increase susceptibility.

Treatment options include: Small; stable haematomas without significant symptoms may be managed with close observation and repeat imaging. Larger or symptomatic haematomas causing significant brain compression require surgical evacuation; often through burr holes for chronic haematomas or a craniotomy for acute. Treatment should always be guided by a qualified Neurosurgery specialist. Do not self-medicate.

While Subdural Haematoma cannot always be fully prevented, several measures can reduce risk: Using protective headgear during high-risk activities and sports; fall-proofing homes for older adults; careful monitoring of patients on blood-thinning medications.

Seek immediate medical attention if you experience symptoms of Subdural Haematoma. This is a serious condition — go to the emergency room or call 112 if symptoms are severe or rapidly worsening.
