Quick Answer
Brain tumors cause symptoms based on location — headache, seizures, personality changes, weakness. Early evaluation and treatment improve outcomes.

Brain tumors are abnormal growths of cells in the brain — ranging from benign (non-cancerous) to malignant (cancerous). Symptoms depend on tumor location, size and growth rate. Early recognition and evaluation improve outcomes, though not all brain tumors are curable.
Common warning signs
New persistent headache (worse in morning, with vomiting), seizures (new-onset in adults), progressive focal neurological deficits (weakness, numbness, vision/speech changes), personality or cognitive changes, unexplained nausea/vomiting, balance problems, papilledema (swelling of optic disc seen on exam).
Location-specific symptoms
Frontal lobe: personality changes, executive dysfunction. Temporal lobe: memory problems, seizures, language issues. Parietal lobe: sensory deficits, neglect. Occipital lobe: visual field defects. Cerebellum: ataxia, coordination problems. Brainstem: cranial nerve deficits, long tract signs.
Diagnosis and treatment
Contrast-enhanced MRI is the definitive imaging test. Biopsy establishes diagnosis (type, grade). Treatment depends on tumor type: surgery (resection), radiation therapy, chemotherapy, targeted therapy, immunotherapy. Benign tumors may be observed or surgically removed. Multidisciplinary neuro-oncology team essential.
When to seek professional evaluation
New neurological symptoms — especially headache, seizures or personality changes — need prompt evaluation to exclude brain tumor.

Not necessarily. A single unprovoked seizure needs full assessment before diagnosing epilepsy. Provoked seizures have different implications.
Protect from injury, do not put objects in mouth, time the event, turn recovery position after jerking, call emergency if >5 minutes or injury.
Migraine is a neurological condition; headache is one feature. Associated symptoms and functional impact are important for diagnosis.
Aura refers to visual, sensory, or speech symptoms that precede the headache in some people. Both types are migraine; the presence of aura may influence management discussion.
Yes. Short or fragmented sleep impairs memory consolidation and lowers migraine threshold. Snoring with apneas fragments sleep and fragments cognition. Dr. Jitendra screens sleep duration, regularity, snoring and caffeine, and refers for sleep study when indicated — often before escalating headache or memory medicines.
