Which symptoms are commonly associated with schizophrenia?

The symptoms commonly associated with schizophrenia include delusions and hallucinations, making this the correct answer. Delusions are false beliefs that are not rooted in reality, often impacting how individuals perceive situations or their surroundings. For example, a person with schizophrenia may have paranoid delusions, believing that others are plotting against them.

Hallucinations involve experiencing sensory perceptions that have no external source, such as hearing voices that others do not hear or seeing things that are not present. These symptoms are fundamental to the diagnosis of schizophrenia and significantly affect an individual’s thoughts, behaviors, and emotional states.

Other choices do not accurately represent the key symptoms of schizophrenia. Frequent headaches are not a defining feature of the disorder, nor are excessive sleeping or strong focus and clarity in thoughts. The latter symptoms might be more relatable to different conditions but are not typical characteristics of schizophrenia.

Understanding these key symptoms is crucial for recognizing the disorder and providing appropriate support or treatment.
