Recovery After Brain Tumor Surgery in India
There's no single number. Anyone who gives you one without knowing your case is guessing. Recovery depends on tumor type, location, how much came out, patient age, and neurological baseline going in. A 35 year old with a fully respected meningioma in a non-eloquent...
Benign vs Malignant Brain Tumors: Key Differences
Nobody explains this properly. So people walk out of consultations thinking benign means safe and malignant means it's over. Neither is quite right. Here's what benign actually means the tumor stays put. It doesn't invade the tissue around it. It won't pack up and...
Warning Signs of a Brain Tumor Not to Ignore
The problem with brain tumor symptoms isn't that they're rare. It's that most of them look exactly like something ordinary. A headache. A bit of dizziness. Forgetting a word mid-sentence. These things happen to everyone and usually mean nothing. But in certain...

Life Expectancy After DBS Surgery for Parkinson’s Disease
This is one of the first questions families ask. And it's the right question but the answer isn't what most people are bracing for. DBS surgery doesn't shorten life expectancy. That's worth saying clearly because the fear going into a brain surgery conversation is...

Here's the thing families always want a cleaner answer to than actually exists. Most people with Parkinson's have no family history of it. Zero. No parent, no sibling, no uncle anyone can trace it back to. And most people who do have a parent with the disease never...
What Happens If Deep Brain Stimulation Stops Working
The first thing to understand is that "DBS stopped working" usually means one of several very different things and which one it is determines entirely what happens next. Sometimes the device is fine and the settings just need adjustment. Sometimes the battery is...
Can Young Onset Parkinson’s Patients Undergo DBS Surgery
Yes. And in many cases, younger patients with Parkinson's are actually stronger DBS candidates than older ones. That surprises a lot of families. The assumption tends to run the other way that surgery is for older patients who've exhausted everything else, and that...
Success Rate of DBS Surgery for Tremors in India
Numbers get thrown around a lot in this conversation. "90% success rate." "85% improvement." They sound reassuring until you ask what success actually means in those studies and whether the patients being measured look anything like your case. The honest answer is...

How to Choose the Right Neurosurgeon in Mumbai

How Does the Brain Recover After a Seizure?
Nobody talks about what happens after the seizure stops. Everyone focuses on the episode itself. Timing it. Getting the person safe. Calling for help. But the recovery that follows, that part carries just as much clinical weight. Sometimes more. The brain doesn't...
