Per DSM-5, at least one of the following has to be present to diagnose schizophrenia except
Hallucinations
Delusions
Disorganized speech
Negative symptoms
The Correct Answer is D
A. Hallucinations are a core positive symptom of schizophrenia and involve false sensory perceptions without an external stimulus (e.g., hearing voices, seeing things that are not there). According to the DSM-5, hallucinations are one of the three essential symptoms that must be present for a diagnosis.
B. Delusions are fixed, false beliefs that persist despite evidence to the contrary (e.g., persecutory delusions, grandiose delusions). Delusions are a hallmark symptom of schizophrenia and are required as a diagnostic criterion if present.
C. Disorganized speech reflects disorganized thinking, a key symptom of schizophrenia. It includes incoherence, tangentiality, and word salad, demonstrating the cognitive dysfunction associated with the disorder. If disorganized speech is present, it fulfils one of the primary diagnostic criteria.
D. Negative symptoms such as avolition, anhedonia, alogia, and flat affect, are common in schizophrenia but are not required for diagnosis. According to the DSM-5, at least one of the following three symptoms hallucinations, delusions, or disorganized speech must be present to meet the diagnostic criteria for schizophrenia.
