Both grade 3 and grade 4 brain tumors are classified as high-grade malignancies under the WHO system, meaning both grow rapidly, infiltrate surrounding tissue, and require aggressive multimodal treatment but they aren't the same disease. Grade 3 tumors, such as...

Craniopharyngioma is a benign, slow-growing tumor that develops near the pituitary gland and hypothalamus, arising from remnants of embryonic tissue left over from fetal development. It doesn't invade surrounding brain tissue the way malignant tumors do, but its...

Brain tumors in children produce symptoms linked to rising pressure inside the skull, damage to surrounding tissue, or disrupted nerve pathways and the specific pattern depends on where the tumor sits and the child's age. Common presentations include recurrent morning...

Managing epilepsy alone requires four things working together: seizure detection technology, home safety modifications, strict medication adherence, and a documented emergency plan shared with someone nearby. Research shows living and sleeping unsupervised raises...

Recovery after brain tumor surgery moves through immediate post-operative monitoring, followed by imaging confirmation, staged rehabilitation and long-term surveillance. The first 24 to 48 hours focus on neurological checks in a critical care setting to catch swelling...

Brain tumor surgery in India ranges from a standard craniotomy for accessible tumors to minimally invasive and endoscopic approaches for lesions sitting in harder-to-reach locations. The surgical plan depends on tumor type, size, location, and how close it sits to...

Hydrocephalus is caused by an abnormal buildup of cerebrospinal fluid within the brain's ventricles, arising from excess fluid production, blocked circulation, or impaired absorption. It can be congenital, present from birth due to structural malformations, or...

A baclofen pump delivers baclofen directly into the intrathecal space at doses roughly 100 times lower than oral equivalents, producing targeted spasticity reduction without systemic side effects. It is indicated when oral baclofen and other muscle relaxants fail to...

A baclofen pump delivers baclofen directly into the intrathecal space at doses roughly 100 times lower than oral equivalents, producing targeted spasticity reduction without systemic side effects. It is indicated when oral baclofen and other muscle relaxants fail to...

Cervical spine surgery is indicated when disc, vertebrae, or spinal canal problems cause persistent neurological deficits, cord compression, or unresolved pain. Primary conditions include disc herniation, spondylotic myelopathy, spinal stenosis, trauma-related...

Stereotactic neurosurgery uses a three-dimensional coordinate system to pinpoint precise targets inside the brain without large open incisions. Pre-operative MRI or CT imaging is mapped to a frame fixed to the skull, guiding instruments, electrodes, or radiation beams...

Dystonia is a movement disorder characterised by sustained or intermittent muscle contractions that produce abnormal postures, repetitive movements, or both. Unlike Parkinson's disease, where DBS produces rapid and predictable motor improvement, dystonia responds to...

Brain tumour surgery is one of the most significant decisions a patient and family will navigate, and the experience from first consultation to discharge is more structured than most people anticipate. At experienced neurosurgical centres, the process follows a...

Patients travelling to Mumbai for deep brain stimulation surgery come from across India and from international destinations, often after exhausting local options or receiving a referral to a centre with dedicated movement disorder surgical expertise. The logistics of...

Recovery after spine surgery ranges from a few weeks to nearly a year, depending on the procedure. Discectomy or foraminotomy allows light activity within two to four weeks. Laminectomy takes six to eight weeks. Spinal fusion is different, since bone needs three to...

Functional neurosurgery, most commonly deep brain stimulation, improves tremor, rigidity, slowness and abnormal postures, though benefit varies by condition. Parkinson's patients see the strongest results, with tremor eased and medication needs dropping. Dystonia...

Minimally invasive spine surgery in India achieves consistently high success rates, with microdiscectomy showing symptom relief in roughly 85 to 95 percent of well-selected patients. Success means meaningful pain reduction, restored mobility and return to normal...

A spinal cord stimulator (SCS) is designed to fit into daily life, not restrict it. Most patients return to work, exercise, and travel within weeks of recovery. Driving needs a few sensible precautions, especially around switching the device off before getting behind...

No single food cures essential tremor, but a consistent, nutrient-dense eating pattern, especially one close to the Mediterranean diet, is linked to milder symptoms and may lower long-term risk. Foods rich in omega-3s, magnesium, B6, and antioxidants support nerve and...

Not all brain tumours require surgery. Treatment decisions are based on tumour type, grade, size, location, rate of growth, and the patient's neurological status at presentation. Benign slow-growing tumours in non-eloquent locations are sometimes monitored with serial...

Deep brain stimulation directly targets the neural circuits responsible for the three core motor symptoms of Parkinson's disease: tremor, rigidity, and bradykinesia. It doesn't reverse the underlying neurodegeneration, but by modulating abnormal signalling in the...

Pituitary tumours are abnormal growths in the pituitary gland, a pea-sized structure at the base of the brain that regulates growth, metabolism, reproduction, and stress response. Most are benign and slow-growing, but their location adjacent to the optic chiasm and...

Deep brain stimulation has been around long enough that its safety record is no longer a guess. Surgeons have been placing electrodes for movement disorders since the early 1990s, and by now there's decades of outcome data across thousands of patients. Still, it's...

Meningiomas are tumours that arise from the meninges, the three-layered membrane covering the brain and spinal cord, making them the most common type of primary intracranial tumour in adults. Most are benign and grow slowly, but their location and eventual size...

Parkinson's medications manage symptoms effectively in the early years, but motor fluctuations, wearing-off episodes, and dyskinesia eventually reduce their reliability in a significant proportion of patients. Deep brain stimulation is a surgical intervention that...

A second opinion after a brain tumour diagnosis isn't a sign of distrust it's a standard step in neurooncology that can alter the treatment plan, surgical approach, and in some cases the diagnosis itself. Brain tumour grading errors, misclassified pathology reports,...

Dementia cannot always be prevented, but research suggests roughly 45% of cases are linked to modifiable risk factors, including high blood pressure, high LDL cholesterol, hearing and vision loss, physical inactivity, and social isolation. Most of these show...

Traumatic brain injury severity is classified using the Glasgow Coma Scale, scoring eye opening, verbal response and motor response from 3 to 15. A score of 13-15 is mild, 9-12 is moderate, and 8 or below is severe. Lower scores mean deeper unconsciousness and greater...

Hydrocephalus is an abnormal accumulation of cerebrospinal fluid inside the brain's ventricles, raising intracranial pressure and progressively damaging surrounding brain tissue. The fluid itself isn't the problem. It's the pressure that builds when normal CSF flow or...

DBS can be combined with medication and other Parkinson's treatments, since each works through a different mechanism. DBS delivers continuous stimulation to reduce tremor, rigidity and motor fluctuations, while levodopa still covers symptoms stimulation doesn't reach,...

Recurrence risk depends mainly on tumour grade, extent of resection, and molecular markers from histopathology. Completely removed low-grade tumours carry far lower recurrence risk than high-grade gliomas, where recurrence is expected; treatment delays it, not...

A stroke occurs when blood supply to part of the brain is interrupted, either by a clot blocking an artery or by a ruptured blood vessel bleeding into brain tissue. A brain hemorrhage is one specific type of stroke, not a separate disease, accounting for roughly 13%...

A craniotomy is one of the most significant surgical decisions a neurosurgeon presents to a patient or their family. It involves temporarily removing a section of the skull to access the brain whether to remove a tumour, drain a blood clot, clip an aneurysm, or...

Dementia cannot always be prevented, but research suggests roughly 45% of cases are linked to modifiable risk factors, including high blood pressure, high LDL cholesterol, hearing and vision loss, physical inactivity, and social isolation. Most of these show...

A pineal gland tumour grows in or around the pineal gland, a small brain structure that produces melatonin and regulates sleep. Its location near major draining veins and the cerebrospinal fluid pathway means hydrocephalus is usually the first sign, often presenting...

Neurotrauma refers to sudden, traumatic damage to the brain, spinal cord, or nerves injuries that can occur in seconds but leave consequences that last years. Road accidents, falls, sports collisions, and industrial incidents are among the most common causes seen in...

Cortical mapping identifies which brain areas control speech, movement, sensation and memory before tissue is removed during surgery. A small electrical current stimulates the brain's surface while the patient performs simple tasks, and any disruption marks a region...

Cubital tunnel compresses the ulnar nerve at the elbow, affecting the ring and little fingers and worsening with prolonged elbow bending. Carpal tunnel compresses the median nerve at the wrist, affecting the thumb, index and middle fingers and flaring with repetitive...

Spinal cord stimulation can cut chronic back and leg pain by half or more. It isn't magic, and it isn't for everyone. A small implanted device sends mild electrical pulses to the spinal cord and scrambles the pain signals before they reach the brain. It works best for...

Most spinal fusion surgeries heal without major problems, but recovery isn't always perfectly smooth. Stiffness, aches, and nerve pain can linger for a while, while issues like hardware problems or nearby spinal wear usually show up much later, if they happen at all....

Standard MRI and fMRI are complementary, not competing. MRI shows the tumour's size, location, and anatomy, while fMRI maps critical functions such as movement, speech, and memory. For tumours near eloquent brain areas, both are essential for safe surgical planning. ...

Recovery after brain surgery is gradual and deeply personal. Expect fatigue, headaches, mood swings, and slower thinking in the early weeks. Most of this eases within months. Some patients regain full function; others need therapy for speech, movement, or memory....

Not the same thing. Not even close. Migraine is a neurological disorder with its own phases, triggers and symptoms that go well beyond head pain. A tension headache and a migraine both hurt. That is where the similarity ends. Treatment that works for one does nothing...

Not the same thing. Not even close. Migraine is a neurological disorder with its own phases, triggers and symptoms that go well beyond head pain. A tension headache and a migraine both hurt. That is where the similarity ends. Treatment that works for one does nothing...

Parkinson's disease is known for tremor, stiffness and slowness of movement. But the non-motor symptoms are just as common, often more disabling and, in many cases, appear years before the tremor is noticed. Loss of smell, constipation, sleep disturbance and...

A non-epileptic seizure looks like epilepsy but produces no abnormal electrical activity in the brain. That single difference changes everything: the diagnosis, the treatment and the outcome. These seizures do not respond to antiepileptic drugs, and prescribing them...

Two brain tumours. Both glial. Both treated with surgery first. After that, the paths diverge significantly. Ependymoma stays local, responds to focal radiotherapy, rarely needs chemotherapy. Astrocytoma spans grade 1 to grade 4, and at the high end, chemotherapy is...

Laminectomy is less invasive. Shorter operation, less blood loss, faster recovery, no implanted hardware. Spinal fusion is larger, screws, rods, bone graft, months before the bone consolidates. But the comparison only matters when both are genuinely options for the...

Carpal tunnel syndrome is compression of the median nerve at the wrist. The nerve supplies sensation to the thumb, index, middle and half the ring finger, and motor power to the thumb muscles. When the tunnel narrows, the nerve gets squeezed. Tingling, numbness and...

Intracranial hypertension. Raised pressure inside the skull that has no room to give. Brain tissue swells, CSF backs up, blood volume rises, and the pressure climbs with it. Trauma, haemorrhage, infection, or no identifiable cause at all. The damage it does to the...

Neither is universally better. MRI is the first investigation and the one that drives surgical planning. PET follows when the question shifts from where the tumour is to how metabolically active it is, or whether a change on post-treatment imaging represents...

Laminectomy removes the lamina, the bony roof of the spinal canal, to take pressure off the spinal cord or nerve roots. Simple concept. One of the most performed spinal operations in the world. It is the standard surgical answer for spinal stenosis when physio and...

Headaches can be a sign of a brain tumour, though they are far more often caused by tension, migraine or other benign conditions. What distinguishes a brain tumour headache is not the pain itself but the pattern: progressive worsening over weeks, worse in the morning,...

DBS can reduce chorea in selected Huntington's disease patients, but that is the limit of what it offers. It does not slow neurodegeneration or address cognitive decline. In patients with existing cognitive impairment, it may worsen it. The evidence base is small,...

A spinal cord injury can cause permanent paralysis. Whether it does depends on one thing above everything else: how complete the damage is. Complete injuries, where nothing gets through below the injury site, carry the highest risk of lasting paralysis. Incomplete...

Encephalitis is inflammation of the brain itself, not the surrounding membranes. Most cases are managed medically in intensive care. Surgery enters the picture only when specific complications develop  haemorrhage, abscess or brain swelling that no drug can reverse....

Brachial plexus repair demands microsurgical training in peripheral nerve reconstruction that sits outside standard neurosurgery. Dr. Gurneet Singh Sawhney brings fellowship training from Japan in functional neurosurgery, with direct experience across stretch...

Neither approach is universally safer. The choice depends on the lesion type, its location and whether the pathology can be reached through a minimally invasive route. Craniotomy offers the widest access for complex pathology. Endoscopic surgery reaches certain areas...

Migraine is a neurological disorder, not just a bad headache. The pain throbs on one side of the head and an untreated attack lasts 4 to 72 hours. About one person in eight has it worldwide. Women outnumber men three to one. Nausea, vomiting, and sensitivity to light...

Brain surgery can lead to permanent memory loss, though this represents a less common outcome of the procedure. Most memory changes settle within weeks to months as post-operative swelling subsides and the brain finds its footing again. Permanent impairment becomes...

Choosing between deep brain stimulation and focused ultrasound depends on the tremor's severity, which side needs treating, and how the patient weighs surgical risk against the trade-offs of each approach. DBS implants electrodes connected to a programmable device,...

TL;DR Exercises won't cure trigeminal neuralgia, but gentle facial relaxation, slow neck stretches, and low-impact activity may ease pain for some people. They work by lowering muscle tension, reducing stress, and calming nerve sensitivity. Start slow and avoid...

TL;DR Failed cervical fusion happens when the neck bones don't heal solidly after surgery. Warning signs include returning neck or arm pain, new numbness or weakness, clicking sounds, and hardware discomfort. Causes range from non-union to adjacent segment disease....

No, fusion is not always needed for multi-level stenosis. Decompression alone, removing the bone or tissue narrowing the canal, is sufficient when the spine remains stable. Fusion becomes necessary when instability is present, such as spondylolisthesis, or when the...

Neuro-oncology is the field that deals with tumours growing in or around the brain, spinal cord, and peripheral nervous system. Some of these are benign and slow-growing. Others are aggressive, fast-moving, and difficult to treat even with the best available...

Size matters more than almost anything else here. Small acoustic neuromas, under about two to three centimetres, suit stereotactic radiosurgery well, controlling growth without ever removing the tumour. Large ones causing brainstem pressure or neurological symptoms...

Intraoperative monitoring tracks spinal cord and nerve function in real time throughout an operation, alerting the surgeon to a problem before it becomes a permanent deficit. Electrodes placed on the patient measure electrical signals travelling along the cord and...

Microdiscectomy removes the herniated part of a lumbar disc that's pressing on a spinal nerve root. It's minimally invasive, done through a small incision, and most patients go home the same day. Leg pain relief tends to be immediate. Back pain and nerve symptoms like...

Three conditions, one label covering all of them: brain vascular malformation. But the similarities stop there. An AVM is an abnormal tangle of arteries and veins connected directly, bypassing the capillary system, high flow, high pressure, lifelong rupture risk. An...

A brain aneurysm does not always mean surgery. Not even close to always. Small, stable, unruptured aneurysms with a low rupture risk are often just watched with serial imaging and nothing more. Where treatment is needed, endovascular coiling or flow diversion seals...

A brain aneurysm is a weak spot in a cerebral artery wall that balloons outward under blood pressure. Most people don't know they have one. When it ruptures, blood floods the space around the brain and the situation becomes immediately life-threatening. The symptoms,...

Parkinson's disease is a progressive neurodegenerative movement disorder caused by the loss of dopamine-producing neurons in the substantia nigra. It presents with tremor, rigidity, bradykinesia, and postural instability. There is no cure, but management significantly...

Migraine is a neurological condition, not just a bad headache. Attacks involve moderate to severe pulsating pain, typically on one side of the head, and come with nausea, light sensitivity, and sound sensitivity that can last hours to days. Management works on two...

Glioblastoma is the most aggressive primary brain tumour there is. Grade 4. Grows fast, infiltrates surrounding brain, and almost always returns. Median survival with the standard treatment package, maximal safe resection, radiotherapy and temozolomide, is around 14...

The spine supports the entire upper body and protects the spinal cord. Most people don't think about it until something goes wrong. By then, years of poor posture, weak core muscles, or prolonged inactivity have already added up. Strengthening the core, correcting how...

Brain tumors produce symptoms by pressing on or displacing surrounding tissue, disrupting the normal electrical and chemical environment of the brain. The specific signs depend on the tumor's location, size, and rate of growth. A slow-growing tumor in a non-eloquent...

Syringomyelia is a fluid-filled cavity inside the spinal cord. Not around it. Inside it. It forms because cerebrospinal fluid can't circulate properly, so pressure builds and the fluid carves out a space in the cord itself. Over time that space grows. The nerve fibres...

A thunderclap headache is a medical emergency until a brain bleed has been excluded. It peaks within seconds and is typically described as the worst headache of the patient's life. The primary concern is a ruptured cerebral aneurysm causing subarachnoid haemorrhage,...

Brachial plexus injuries can often be surgically repaired, though the outcome depends on the type of damage and how quickly treatment begins. A stretch injury may recover without intervention. A rupture can be bridged with a nerve graft. An avulsion, where the root is...

Carpal tunnel syndrome does not always require surgery. Splints, rest and steroid injections settle the milder cases effectively. Surgery is indicated when the median nerve is under genuine threat, constant numbness, a weakening grip, or the thumb muscle starting to...

Surgery for normal pressure hydrocephalus does not cure it, but the right patient can see a dramatic reversal of symptoms. A shunt drains excess cerebrospinal fluid off the brain, relieving the pressure behind the gait disturbance, cognitive decline and bladder...

Normal pressure hydrocephalus gets misread as dementia all the time, because the two look so alike from the outside. Memory slipping. A shuffling, unsteady walk. Trouble with the bladder. But here's the part that matters: NPH is a fluid problem, not a dying-brain...

Post-concussion syndrome is when concussion symptoms refuse to clear up on schedule. They should settle in a week or two. With this lot, they don't, they linger for weeks, sometimes months. Headaches. Brain fog. Dizziness, mood dips, sleep that won't behave. No single...

For most people, conservative treatment is right. The large majority of slipped discs settle with physiotherapy, medication and a bit of patience, no operation needed. Surgery is the right call when the nerve's in danger, real weakness, a foot that's dropping, or pain...

Most sciatica never needs surgery. Physiotherapy, time and pain relief settle the large majority within a few weeks. Surgery steps in when the nerve is in real trouble, spreading weakness, a dropping foot, or pain that simply won't quit despite proper conservative...

For the right patient, yes. Spinal cord stimulation can cut chronic back and leg pain by half or more. It isn't magic, and it isn't for everyone. A small implanted device sends mild electrical pulses to the spinal cord and scrambles the pain signals before they reach...

Mesial temporal sclerosis is scarring in the temporal lobe. The hippocampus, specifically, deep inside. It's the commonest reason temporal lobe epilepsy stops responding to medication. And yes, in the way that counts, it can be cured. The scar won't melt away, nobody...

Syringomyelia needs surgery when the cyst inside the spinal cord is growing, or when the symptoms keep getting worse. A small one that causes nothing usually gets watched, not cut. And here's what most people miss: the surgery rarely targets the cyst itself. It goes...

Neither is simply better, the right choice depends on what's being treated and how complex it is. Minimally invasive surgery uses small incisions and causes less muscle damage, so recovery is faster and pain is lower. Open surgery gives wider access, which matters for...

Surgery is better than radiation for brain metastases when the tumour is large, pressing on the brain, or causing symptoms that need quick relief. It's also the choice when doctors need tissue to confirm the diagnosis. Radiation suits small, deep or multiple lesions...

A baclofen pump treats spasticity by delivering the muscle relaxant straight into the fluid around the spinal cord, where it acts directly on the overactive nerve signals. A small programmable device sits under the abdominal skin, and a thin catheter delivers the drug...

Medicines stop working for essential tremor when the tremor outgrows what the drug can suppress, or when side effects cap the dose before it helps. Propranolol and primidone are the usual first choices, and they ease shaking in roughly half of patients, rarely more....

DBS surgery doesn't stop Parkinson's tremors completely, but it reduces them sharply in most patients. Deep brain stimulation sends steady electrical pulses into the movement-control regions of the brain, settling the abnormal signals that drive shaking. Tremor...

Epilepsy is a chronic neurological disorder defined by recurrent, unprovoked seizures from sudden bursts of abnormal electrical activity in the brain. The triggers vary from one patient to the next, genetic mutations, head injury, stroke, brain tumours, or central...

DBS surgery and levodopa treat Parkinson’s disease through entirely different mechanisms. Here is how they differ and when surgery becomes the better option.

TL;DR Life Expectancy After Spinal Fusion Spinal fusion does not reduce life expectancy in the majority of patients. Long-term outcomes depend on the underlying condition, age, and overall health — not the procedure itself. Most patients return to normal daily life...

TL;DR Warning Signs of a Seizure in Adults Seizure warning signs in adults — aura, sudden confusion, staring spells, or post-episode fatigue — are frequently missed or mistaken for stress. Recognising these early allows for faster diagnosis and better seizure control....

Spinal cord stimulation is a neuromodulation option for chronic, severe neuropathic pain that has stopped responding to medication, physiotherapy, or nerve blocks. The strongest results show up in patients with Failed Back Surgery Syndrome, Complex Regional Pain...

DBS surgery and levodopa treat Parkinson’s disease through entirely different mechanisms. Here is how they differ and when surgery becomes the better option.

A seizure happens when a sudden burst of abnormal electrical activity in the brain disrupts the normal signalling between neurons. Large groups of nerve cells fire together at high speed, almost like an electrical storm, and the activity either stays confined to one...
