In brain abscess, which symptom is most commonly present?

Explanation:
Headache is the most common symptom because a growing brain abscess increases intracranial pressure and irritates the meninges, producing persistent, often generalized head pain that patients notice early. Fever can accompany an infection but isn’t universal and may be absent, especially early or with antibiotic treatment. Altered mental status and seizures arise from edema, mass effect, or cortical irritation, but they occur less frequently as the initial presenting features. So, while fever and focal signs can occur, headache is the keynote symptom you’re most likely to see first.
