What is one of the causes in the differential diagnosis for seizures?

Abscess formation is a notable cause in the differential diagnosis for seizures due to its potential to increase intracranial pressure or irritate the surrounding brain tissue. When an abscess develops, whether due to a bacterial infection or other pathological processes, it can alter the normal neuronal function and lead to convulsive activity. An abscess is localized, often resulting from infections such as bacterial meningitis or cerebral infections, and the resulting inflammation can disrupt electrical activity in the brain, causing seizures.

In contrast, while hypertension can lead to other acute neurological events such as strokes that may manifest with seizures, it is not a direct cause of seizure activity. Cholesterol dysregulation primarily affects cardiovascular health rather than acting directly on the brain's electrical conductivity. Acid-base imbalances can have a broad range of systemic effects and might lead to seizures under extreme circumstances, but abscess formation is more direct in terms of affecting brain structure and function responsible for seizure generation.
