What is a hallmark symptom of schizophrenia?

A hallmark symptom of schizophrenia includes delusions and hallucinations, which are key features of the disorder. Delusions are false beliefs that are strongly held despite evidence to the contrary, while hallucinations involve experiencing sensations that are not present, such as hearing voices or seeing things that others do not. These symptoms significantly affect an individual's perception of reality and can lead to severe impairment in function and distress.

The presence of delusions and hallucinations distinguishes schizophrenia from other mental health conditions, making it essential in the diagnosis and understanding of the disorder. Recognizing these symptoms allows healthcare professionals to implement appropriate treatments and support for affected individuals.
