Headache is one of the most common health complaints, and most headaches are not caused by any serious disease. They are usually linked to tension, migraine, poor sleep, eye strain or sinus problems. Rarely, a headache can be a sign of a serious problem in the brain, such as bleeding, infection or a tumour, so it is important to know the warning signs.
Headaches differ in their pattern. Common types and their usual features are:
Common triggers include stress, poor sleep, skipped meals, not drinking enough water, long hours on screens, uncorrected eyesight, sinus infection, neck strain, and too much tea, coffee or alcohol. Less common but more serious causes include bleeding in or around the brain, brain tumour, meningitis, build-up of fluid in the brain (hydrocephalus), raised pressure inside the skull and blood clots in the veins of the brain.
In most cases the diagnosis is made from a detailed history and a careful neurological examination, and no scan is needed. A headache diary noting the timing, triggers and medicines taken is very useful. A CT or MRI scan of the brain is advised when there are warning features, an abnormal examination, or a clear change in the usual headache pattern.
Most headaches are treated with lifestyle changes and medicines. Regular sleep, regular meals, enough water, managing stress, regular exercise and limiting screen time help many people. Simple pain relievers can be used for occasional headaches, but they should not be taken on more than a few days a week, as overuse can itself cause daily headaches. For frequent migraine or other recurring headaches, a doctor may advise preventive medicines.
A neurosurgeon's role is to evaluate the headache, rule out serious causes and treat conditions that need surgery, such as a brain tumour, bleeding or hydrocephalus. Only a small number of patients need surgery.
If you notice any of these, go to the nearest emergency immediately.
If your headaches are frequent, severe or changing in pattern, consult Dr. Prashant Sharma for a careful evaluation.
