Which of the following best describes psychosis?

Psychosis is best described as a major mental disorder characterized by the presence of delusions and hallucinations. This condition significantly impacts an individual’s perception of reality, often leading to impaired functioning and distress.

Delusions are false beliefs that are strongly held despite clear evidence to the contrary. For example, a person with psychosis may believe that they are being watched or followed, even when no one is there. Hallucinations involve experiencing things that are not present, such as hearing voices or seeing things that others do not. These symptoms create a profound disconnect from reality, which is the hallmark of psychotic disorders.

The other options describe different mental health or physical conditions that do not align with the defining characteristics of psychosis. Emotional disorders primarily involve feelings and emotional states, while physical conditions concern bodily health rather than mental processes. Eating disorders specifically relate to issues with food and body image, again not capturing the essence of psychotic experiences. Thus, the choice that accurately encompasses the nature of psychosis is the one focusing on delusions and hallucinations as fundamental features of this major mental disorder.
