What is 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.
Severe
Uncommon overall but increasingly common in older adults, particularly those on anticoagulant therapy
No
Causes of Subdural Haematoma
Most commonly caused by head trauma such as a fall, motor vehicle accident, or assault, which tears small blood vessels bridging the brain surface and its covering. Chronic subdural haematomas often occur in older adults or those on blood-thinning medications after even minor, sometimes forgotten, head injuries because brain shrinkage with age stretches these bridging veins. Risk factors include advanced age, chronic alcohol use, anticoagulant medication use, and a history of falls.
Symptoms of Subdural Haematoma
Headache, confusion or altered mental status, drowsiness or difficulty staying awake, weakness on one side of the body, slurred speech, nausea and vomiting, seizures, in acute severe cases, loss of consciousness or coma
Treatment & Types of Subdural Haematoma in Telangana
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, larger bleeds. Reversal of any blood-thinning medications and close neurological monitoring in a hospital setting are essential parts of management.
Subdural haematomas are classified by how quickly they develop: acute, forming rapidly within minutes to hours after severe head trauma and often requiring emergency surgery; subacute, developing over several days; and chronic, developing slowly over days to weeks after a relatively minor, sometimes forgotten, head injury, particularly common in older adults or those on blood-thinning medication. This timing distinction matters greatly for treatment, since acute haematomas often need urgent craniotomy while chronic ones can sometimes be managed with observation or a less invasive burr-hole procedure.

Frequently Asked Questions
Why do chronic subdural haematomas happen more often in older adults?
Brain shrinkage with age stretches the small bridging veins between the brain's surface and its outer covering, making them more prone to tearing even after minor, sometimes forgotten, head injuries. This is why unexplained new confusion or headache in an older adult, even without a clear injury history, prompts consideration of this condition.
Does a subdural haematoma always require surgery?
No, small, stable haematomas without significant symptoms may be managed with close observation and repeat imaging, while larger or symptomatic ones causing significant brain compression require surgical evacuation. The decision depends on the size of the bleed, the symptoms present, and how it changes on follow-up scans.
Can someone on blood thinners be at higher risk?
Yes, anticoagulant medication use is a significant risk factor since it impairs the blood's ability to clot and stop bleeding after even a minor head injury, so reversing these medications is often an essential part of emergency treatment. Careful monitoring of patients on blood thinners after any head injury, however minor it seems, is important.
How urgent is it to seek care after a head injury even if symptoms seem mild?
Prompt medical evaluation is recommended after any head injury since chronic subdural haematomas can develop slowly and cause worsening symptoms over days to weeks even when the initial injury seemed minor. Watching for new headache, confusion, drowsiness, or weakness in the days after a head injury is important, even one that seemed unremarkable at first.
Can a person fully recover after surgery for a subdural haematoma?
Many people, particularly those treated promptly for a chronic haematoma, recover well, though outcomes for acute, severe haematomas depend heavily on how much brain compression occurred before surgery. Close neurological monitoring during recovery helps track improvement and catch any complications early.
