What are the causes, symptoms, and treatment options for subdural hematoma?

A subdural hematoma is a serious medical condition where blood collects between the brain and its outer protective layer, the dura mater, usually following a head injury, fall, or use of blood thinner medication. Common symptoms include persistent headache, confusion, weakness, dizziness, and vomiting. Mild cases may be managed through close observation, while severe cases require prompt subdural hematoma surgery to relieve pressure on the brain. Early diagnosis and timely treatment significantly improve outcomes.

In subdural hematoma, the clock matters more than the clot. The earlier we drain it, the better the recovery, even when the bleed looks small on the first scan. Dr. Gurneet Singh Sawhney,  Neurosurgeon in Mumbai

Caught early, most are fixable. India has every option you’d want, surgical or otherwise. Here’s the rundown what causes it, what it looks like, how it’s treated.

The major causes of subdural hematoma include head injury from falls, road accidents, sports impact, or physical assault, with the risk significantly higher in patients taking blood thinners such as aspirin or warfarin or those with underlying bleeding disorders. Older adults are particularly vulnerable because age-related brain shrinkage stretches the bridging veins, making them more likely to tear even with minor head impact.

Other contributing factors include chronic alcohol use, repeated head trauma in contact sports, and shaken baby syndrome in infants. Early consultation with a subdural hematoma specialist significantly improves recovery outcomes.

Symptoms come down to one thing speed of the bleed. Fast bleed after a hard hit? Person can collapse on the spot. Slow bleed? Weeks may pass before anything shows.

Things to watch out for:

• A headache that won’t quit, only worsens
• Confusion, memory slips, can’t focus
• Slurred words, sudden mood swings
• Dizzy, off-balance, walking funny
• Nausea, vomiting
• Weakness or numbness on one side
• Drowsy, blurred vision, orseizures

Spotted any of these after a head injury? Don’t sleep on it. Get to a neurosurgeon. Today.

First test? A non-contrast CT scan. Quick, sharp, shows fresh bleeding and clot size right away. MRI comes in for the smaller stuff, the older stuff, the chronic bleeds CT might miss.

Sometimes, doctors throw in a cerebral angiography to rule out a vessel issue. Thin catheter goes in through the groin artery, threads up to the brain. Contrast dye lights up the blood flow on X-ray. That’s it.

Imaging plus a hands-on neurological exam alertness, reflexes, motor checks. Most centres use the Glasgow Coma Scale to score it. Once it’s confirmed, urgent referral for brain surgery in Mumbai is usually next.

Depends on the bleed size, the symptoms, the patient’s overall shape. Tiny clot, no symptoms? Just keep an eye on it with repeat scans. Bigger? Symptomatic? Time to drain it and bring the pressure down.

What neurosurgeons in India usually go with:

Anti-epileptics, mannitol, corticosteroids these usually ride along with surgery to manage skull pressure and stop things from getting worse.

Speed is the whole game. Wait too long and the bleed grows. So does the chance of permanent damage. Drain it fast and recovery looks a whole lot better. For trickier cases, functional neurosurgery in Mumbai brings sharper surgical precision to the table.

Younger ones bounce back quicker. Older patients? Longer rehab. And rebleed risk runs higher if they’re still on long-term blood thinners.
