What are common symptoms of schizophrenia?

The option highlighting delusions of grandeur and hallucinations is correct because these are hallmark symptoms of schizophrenia. Schizophrenia is a severe mental disorder characterized by a range of cognitive, behavioral, and emotional dysfunctions. Delusions are false beliefs that are not grounded in reality, and delusions of grandeur refer to an inflated sense of self-importance or abilities. Hallucinations, particularly auditory ones, involve perceiving things that are not present, such as hearing voices.

Understanding these symptoms is crucial because they significantly impact a person's functioning and perception of reality. Identifying them can assist in early intervention and appropriate treatment, ultimately improving the quality of life for those affected.

Other options, while they may describe symptoms of different mental health conditions, do not specifically align with the core symptoms of schizophrenia. Extreme fatigue and sleep disturbances can relate to various disorders, but they are not defining characteristics of schizophrenia. Mood swings and anxiety are more typical of mood disorders, and fear of public speaking is usually associated with anxiety disorders rather than schizophrenia.
