Which disorder includes symptoms such as hallucinations, irrational beliefs, and lack of motivation?

The disorder that includes symptoms such as hallucinations, irrational beliefs, and lack of motivation is Paranoid Schizophrenia. This condition is characterized by the presence of psychotic symptoms, particularly delusions and hallucinations, which can significantly distort an individual's perception of reality. Individuals with this disorder often experience intense paranoia, believing that they are being persecuted or conspired against, which is a type of irrational belief.

Additionally, lack of motivation, known as avolition, is a common symptom in schizophrenia. It affects an individual's ability to engage in daily activities and pursue goals, often leading to social withdrawal and difficulty functioning in various aspects of life.

Generalized Anxiety Disorder is characterized by excessive worry and anxiety about multiple aspects of life, while Panic Disorder involves sudden episodes of intense fear but does not include hallucinations or significant irrational beliefs as core symptoms.
