    • Erratic speech and behavior
    • Inappropriate emotions

    Paranoid schizophrenia:

    • Delusions that other people want to harm them
    • Hear things that aren’t there

    Paranoid schizophrenia tends to have a better outlook than other subtypes.

    • Indifference (apathy)
    • Lack of energy and motivation
    • Blank look (minimal facial expressions)
