What type of symptoms might be seen in individuals with schizophrenia spectrum disorders?

Individuals with schizophrenia spectrum disorders can exhibit both positive and negative symptoms, which is why this answer is the most accurate representation of the disorder.

Positive symptoms refer to the presence of abnormal behaviors, thoughts, or perceptions that are not typically seen in individuals without the disorder. These include hallucinations (such as hearing voices), delusions (firmly held false beliefs), and disorganized thinking or speech.

Negative symptoms, on the other hand, reflect a decrease or loss of normal functions or behaviors. This includes diminished emotional expression (flat affect), lack of motivation (avolition), social withdrawal, and an inability to experience pleasure (anhedonia).

The combination of both positive and negative symptoms is critical for diagnosing schizophrenia spectrum disorders and helps in understanding the multifaceted nature of these conditions. In contrast, symptoms like solely motor or cognitive deficits would not encompass the full clinical picture necessary for a diagnosis in this category. Hence, recognizing the presence of both symptom types provides a more comprehensive understanding of the disorder and its impact on individuals.
