Unveiling the Mind: A Comprehensive Review of Psychiatric Disorders in Parkinson’s Disease

Abstract

Abstract Background/Aim: The primary objective of this research was to evaluate the findings and conclusions presented in existing literature articles pertaining to mental illnesses in patients with Parkinson’s disease. Patients and Methods: The study used a patients and methods approach. The study also comprised studies and papers that provided information on clinical aspects, as well as links and correlations between Parkinson’s disease and mental illnesses. Results: Symptoms of mental disorders are extremely prevalent in PD, but they are frequently undetected, undertreated, and overlooked if not evaluated precisely. Neuropsychiatric disorders of Parkinson’s disease divide into a number of major groups: anxiety and mood disorders, psychosis, behavioral modifications such as sexual disorders, impulse control disorders, dopaminergic medication abuse, and sleeping disorders. Conclusion: The majority of mental health conditions in PD are treatable, and failure to do so has a negative impact. Numerous investigations demonstrate that psychiatric symptoms influence the quality of life more than motor manifestations. Depression seems to be associated with deterioration in cognitive performance, tasks associated with everyday living, and motor performance and might have the greatest influence on the quality of life in PD. Psychosis is the leading cause of caretaker concern and a significant predictor of nursing residence relocation. The objective of therapy for mental illnesses in PD ought to include remission; inadequate treatment must be avoided.
