The main symptoms of pellagra are dermatitis, dementia, and diarrhea.

Primary pellagra is due to a diet that does not contain enough niacin and tryptophan. Secondary pellagra is due to a poor ability to use the niacin within the diet.

Additionally, where is pellagra most commonly found? Pellagra is common in poor parts of the world, such as Africa and India, where corn (or maize) is a staple food.
