Pellagra is classically characterized by four symptoms; which one is not among them?

Explanation:
Pellagra stems from niacin deficiency and shows a characteristic four-part picture: dermatitis, diarrhea, dementia, and, if not treated, death. The dermatitis is typically a photosensitive rash in sun-exposed areas, diarrhea reflects gastrointestinal involvement, and dementia arises from nervous system impact. Seizures are not part of these classic signs, though neurological issues can occur. So the symptom that does not belong to the traditional presentation is seizures.
