Introduction: Previous studies reported stroke patients exhibited poststroke behavioral disinhibition (PSBD). The prevalence rates across studies were inconsistent and vary widely (ranged from 5 to 76%). Moreover, the clinical correlates of PSDB were unknown. Therefore, this study aimed to determine the prevalence of PSDB and its correlates with clinical variables, i.e. functional dependence, cognitive functioning, anxiety and depressive symptoms, after 3-month after stroke. Methods: Stroke survivors who had ischemic stroke admitted to the Acute Stroke Unit of the Prince of Wales Hospital from September 2016 to April 2017 were recruited. PSBD was assessed by the disinhibition subscale of the Chinese version of the Neuropsychiatric Inventory (CNPI), which was responded by the caregivers. The stroke survivors’ functional dependence, anxiety and depressive symptoms were assessed by Barthel Index, the anxiety subscale of the Hospital Anxiety Depression Scale, and the Beck Depression Inventory respectively. Results: Twenty-eight stroke survivors were recruited, 9 were excluded due to the absence of caregivers (n = 8) and history of schizophrenia (n = 1). Thus, 19 stroke survivors and their caregivers were assessed. The mean age of the stroke survivors was 67.11 (SD = 6.79) and 11 (57.9%) were male. The types of caregiver were spouse (63.2%), children (26.3%), and others (10.5%). None of the caregivers reported the presence of behavioral disinhibition of the corresponding stroke survivors. Conclusion: PSBD is uncommon amongst ischemic stroke survivors in Hong Kong. Acknowledgement: The project is supported by the Direct Grant for Research 2015/2016 (Round 1) Ref. No. 2015.1.061
Michalina Radomska has received a Master degree in Clinical and Cognitive Psychology from Faculty of Psychology and Educational Sciences at University of Geneva, Switzerland. She is currently working as an assistant and clinical psychologist in Psychopathology and Cognitive Neuropsychology Unit at University of Geneva. She is also pursuing her PhD in psychology in the field of psychological outcomes of Deep Brain Stimulation for Parkinson Disease. Her main research interest lies in the understanding of the relationship between preoperative expectations and postoperative psychological adjustment in PD patients.
Statement of the Problem: Clinical studies in epileptic patients (EP) successfully treated with temporal lobectomy have identified a range of psychosocial postoperative maladjustments. Such postoperative issues have also been reported in patients treated with Deep Brain Stimulation (DBS). Researchers have suggested that presurgery unrealistic or unspecific expectations may lead to adverse outcomes, despite significant improvements in objective measures. Although various assessments of expectations have been used, there is no validated tool clearly focusing on expectations or hopes related to surgical treatment for neurological diseases. The main purpose of this study was thus to develop an instrument assessing presurgery expectations / hopes and to explore its psychometric properties across two clinical populations: patients undergoing epilepsy surgery and patients qualified for the DBS. Methodology: The Treatment Hope and Expectations Questionnaire (THEQ) was elaborated following a thorough review of relevant literatures. It consists in 22 statements exploring four expectations domains (daily living activities, mental and physical health, psychological wellbeing, social-relational life). Each domain is assessed on 3 subscales: realistic expectations, hopes and current state (control measure). The THEQ was completed by 30 DBS and 30 EP before the planned surgery. Findings: The THEQ had good psychometric properties. Paired t-tests conducted on realistic expectations and hope total scores (i.e., cross-domains) revealed that both EP and DBS patients reported significantly higher hopes than realistic expectations. Moreover, the two groups were characterized by high expectations and hopes for the "mental and physical health" domain. Nevertheless, DBS patients had significantly higher expectations and hopes for the “social-relational life” domain as compared to EP. By and large, DBS patients’ expectations and hopes were more attuned towards psychological or interpersonal improvements as compared to EP
