Disexecutive functions and depression in patients with Parkinson disease: the impact on rehabilitation outcome.

BACKGROUND: Studies relating to patients with Parkinson disease that assess neuropsychologic, psychologic, and clinical aspects are very uncommon. OBJECTIVE: The aim of this study was to analyze the impact of executive functioning (impaired vs. not impaired) or depression (depressed vs. nondepressed) on the outcome of rehabilitation treatment in patients with Parkinson disease without dementia at the medium stage of disease. METHODS: Forty consecutive inpatients affected by Parkinson disease were psychologically and neuropsychologically assessed by means of standardized tests during the first week of admission and at discharge after undergoing an intensive rehabilitation training. RESULTS: At baseline, the patients (mean [SD] age, 70.1 [8.0]; Mini-Mental State Examination [MMSE], ≥24) showed impairment in the following executive functions: frontal functions (32.5%), selective and divided attention (55.0% and 41.9%, respectively), and word fluency (17.5%). Depressive symptoms reported using the Geriatric Depression Scale were distributed as follows: mild (n = 13), 32.5%; moderate (n = 4), 10.0%; and severe (n = 5), 12.5%. As for the outcome of the intensive rehabilitation treatment, a general improvement in the Unified Parkinson's Disease Rating Scale, the Berg's scale, the 6-min walking test, and the Timed Up and Go test was observed (P < 0.0001). The improvement was homogeneous for all groupings of the patients for all of the considered variables, indicating that the changes in performance as a result of treatment were unaffected by the presence of executive function deficits or moderate-to-severe depression. CONCLUSIONS: The patients' executive function impairment or moderate-to-severe depressive symptoms did not seem to interfere with the outcome of the intensive physical and occupational rehabilitation. Therefore, these aspects in patients without dementia should not be considered a contraindication to an intensive rehabilitation program. Furthermore, despite the presence of impaired executive functions and/or of depressive symptoms, the 4-wk multidisciplinary rehabilitation program resulted to be highly effective.

[Neuropsychological evaluation and psychological intervention on patients with Parkinson's disease in physical rehabilitation]. / Valutazione neuropsicologica e intervento psicologico nei pazienti con malattia di Parkinson in riabilitazione motoria.

OBJECTIVE: Parkinson's Disease (PD) is characterized by a wide range of motor and non-motor symptoms. In the last years the evaluation of cognitive functioning, emotional aspects and health status of PD patients has became ever-growing important. METHODS: In this article a neuropsychological and psychological assessment model, by means of tests and interviews, and a clinical approach to the narrative themes are described. Areas of clinical investigation: cognitive processing, emotional acceptance and behavioural adaptation to the disease, motivation to rehabilitation treatment, expectations regarding functional recovery, adherence, social and family perceived support, mood, awareness of possible cognitive deficits. Tests assessment (based on specific cognitive deficits related to PD): MMSE, FAB, TMTA-B, Phonological verbal fluency test, Stroop test, Geriatric Depression Scale (GDS) or Beck Depression Inventory- BDI-II and Parkinson's Disease Questionnaire-8 (PDQ-8). The psychological approach, which is part of an interdisciplinary rehabilitative intervention, is based on Cognitive Behavioural Therapy and it is focused on disease management even in the absence, sometimes, of a significant general emotional status modification and it is aimed at improving patient's adaptability, self-management and empowerment. In order to describe the model, the clinical and test data of two PD patients are illustrated. CONCLUSIONS: The added value of this psychological approach lies in the clinical data integration of the test evaluation, the narrative aspects and the information mediated by the inter-professional team. This model allows a deeper and more personalized identification of the patient's subjective adjustment process according to his/her personal needs and resources.
