title: [Headaches in nonneurologic diseases].
abstract: Headaches can be classified into primary and secondary headaches. Typical examples of primary headaches are migraine, tension-type headache and cluster headache. Secondary headaches in internal medicine might be due to hypertensive encephalopathy, lung diseases, metabolic and endocrine diseases and disturbances of electrolytes like increased and decreased serum calcium levels. Ibuprofen, immunoglobulins, and antibiotics might lead to aseptic meningitis. Drug-induced headaches are seen after use of nitroglycerine, calcium channel blockers and immunoglobulins.
