Delusional disorder is a rare and often misunderstood psychiatric condition characterized by persistent, non-bizarre delusions that lack significant hallucinations or cognitive impairment. Unlike schizophrenia, individuals with delusional disorder maintain relatively normal functioning aside from their fixed false beliefs, which can center on themes such as persecution, jealousy, grandiosity, or somatic concerns. The disorder presents diagnostic challenges due to its subtle onset and the resistance of affected individuals to seeking treatment. This article explores the etiology, symptomatology, diagnostic criteria, and treatment approaches for delusional disorder, including pharmacological and psychotherapeutic interventions. Given the impact of delusions on personal and social relationships, early recognition and tailored management strategies are crucial for improving patient outcomes. Future research is needed to enhance understanding of its neurobiological underpinnings and develop more effective treatment modalities.
