Welcome to Harry Potter Answers. What would you like to know?

The Carrows (Alecto and Amycus), who were Death Eaters and the Muggle Studies and Dark Arts teachers in The Deathly Hallows, tortured Neville and other students who stood up to them.

Neville had difficulties with other professors before the Carrows, although their treatment of him could not be specifically classified as torture. Professor Snape's treatment of Neville was harsh and frightened Neville severely (his boggart was Severus, in POA). Also, Barty Crouch Jr., disguised as Alastor Moody, caused Neville emotional trauma when he used the Cruciatus Curse on a spider, since Neville's parents had lost their sanity to the Cruciatus Curse.
