The association between the severity of poststroke depression and clinical outcomes after first-onset stroke in Korean patients

Exploratory analysis of the effectiveness of virtual reality in cardiovascular rehabilitation

Virtual reality therapy has been shown to be effective in coping with psychological disorders accompanied by cardiovascular disease. Age appears to be a factor that can affect the effectiveness of psychological therapy in a virtual environment. Therefore, the aim of the study was to explore whether there are age-related differences in the effectiveness of reducing levels of depression and anxiety during a virtual reality psychological intervention implemented for rehabilitation. The study included 25 younger (< 65 years) and 25 older (65 +) patients with cardiovascular disease who participated in virtual reality therapy to cope with anxiety and depression. The Hospital Anxiety and Depression Scale was used to assess anxiety and depressive disorders before and after intervention. Significant reductions in anxiety and depression scores after intervention were observed in both age-matched groups, and no significant differences were found between the younger and older participants. Further evaluation of patient age as a predictor of the effectiveness of psychological intervention in virtual reality did not show a significant effect of age on effectiveness in reducing anxiety and depressive disorders. The results obtained suggest that older patients benefit similarly to younger patients from psychological intervention in a virtual environment. Furthermore, age does not appear to be considered a predictor of effectiveness in reducing the level of anxiety and depression in patients with cardiovascular disease using virtual reality therapy.

Impact of depression on stroke outcomes among stroke survivors: Systematic review and meta-analysis

BACKGROUND

Depression may negatively affect stroke outcomes and the progress of recovery. However, there is a lack of updated comprehensive evidence to inform clinical practice and directions of future studies. In this review, we report the multidimensional impact of depression on stroke outcomes.

METHODS

Data sources. PubMed, PsycINFO, EMBASE, and Global Index Medicus were searched from the date of inception. Eligibility criteria. Prospective studies which investigated the impact of depression on stroke outcomes (cognition, returning to work, quality of life, functioning, and survival) were included. Data extraction. Two authors extracted data independently and solved the difference with a third reviewer using an extraction tool developed prior. The extraction tool included sample size, measurement, duration of follow-up, stroke outcomes, statistical analysis, and predictors outcomes. Risk of bias. We used Effective Public Health Practice Project (EPHPP) to assess the quality of the included studies.

RESULTS

Eighty prospective studies were included in the review. These studies investigated the impact of depression on the ability to return to work (n = 4), quality of life (n = 12), cognitive impairment (n = 5), functioning (n = 43), and mortality (n = 24) where a study may report on more than one outcome. Though there were inconsistencies, the evidence reported that depression had negative consequences on returning to work, functioning, quality of life, and mortality rate. However, the impact on cognition was not conclusive. In the meta-analysis, depression was associated with premature mortality (HR: 1.61 (95% CI; 1.33, 1.96)), and worse functioning (OR: 1.64 (95% CI; 1.36, 1.99)).

CONCLUSION

Depression affects many aspects of stroke outcomes including survival The evidence is not conclusive on cognition and there was a lack of evidence in low-income settings. The results showed the need for early diagnosis and intervention of depression after stroke. The protocol was pre-registered on the International Prospective Register of Systematic Review (PROSPERO) (CRD42021230579).

Factors associated with the effectiveness of immersive virtual therapy in alleviating depressive symptoms during sub-acute post-stroke rehabilitation: a gender comparison

BACKGROUND

The large-scale digitalization of healthcare has induced shifts in patient preferences, prompting the introduction of therapies utilizing novel technologies. In this context, the targeted application of these interventions is deemed as crucial as assessing their overall effectiveness. The aim of this study was to characterize the patient profile who benefited most from immersive virtual reality (VR) therapy.

METHODS

Based on the results from the previous randomized controlled trial study, we employed an exploratory study design to determine the factors associated with the most significant mental health improvement. A secondary analysis was conducted on a sample of 83 participants, with further analysis of participants with elevated depression symptoms, as indicated by a score of > 10 on the 30-item Geriatric Depression Scale (GDS-30). Both groups participated in a similar post-stroke rehabilitation program; however, the experimental group also received additional VR therapy through an immersive VR garden intervention. The GDS-30 was used to assess mood and depressive symptoms, and sociodemographic, cognitive status as well as stroke-related variables were considered as potential factors.

RESULTS

In both the experimental (mean change 5.3) and control groups (mean change 2.8), interventions significantly reduced depressive symptoms, with a more pronounced difference in the experimental group (p < 0.05). When examining gender differences, women exhibited greater improvement in the GDS, with mean between-group differences of 5.0 for the total sample and 6.0 for those with elevated depressive symptoms. Sociodemographic factors, cognitive status, and time from stroke were not found to be factors that alter the effectiveness of VR therapy.

CONCLUSIONS

While VR therapy as an adjunctive treatment for post-stroke rehabilitation seems especially effective for women with elevated depressive symptoms, the results should be interpreted with caution due to the study's small experimental group size. Traditional methods showed reduced effectiveness in women compared to men; thus, developing technologically advanced and gender-specific approaches can lead to more tailored therapy.

Effects of Immersive Virtual Therapy as a Method Supporting Recovery of Depressive Symptoms in Post-Stroke Rehabilitation: Randomized Controlled Trial

PURPOSE

Depressive symptoms constitute an important group of mental problems that alter the course of post-stroke rehabilitation by reducing quality of life, physical activity, social functioning, and interpersonal relationships. Although several studies have shown the efficacy of virtual reality (VR) in the motor treatment of poststroke patients, there is a lack of studies that would also evaluate the impact of VR on psychological aspects. Thus, we investigated the effectiveness of immersive VR therapy on both functional activity and depressive symptoms in stroke survivors.

PATIENTS AND METHODS

We conducted a single blind, randomized controlled trial comparing VR therapy with Schultz's Autogenic Training (SAT). Patients randomized to the VR group received treatment in an immersive VR therapeutic garden with elements of psychotherapy and physical activity of the upper extremities, whereas patients in the control group received SAT. Additionally, patients in both groups received standard neurological rehabilitation. The full research cycle lasted six weeks. We used Geriatric Depression Scale, Generalized Self-Efficacy Scale, Acceptance of Illness Scale, Visual Analogue Scale of pain, Hospital Anxiety and Depression Scale, Barthel Index, Lawton Instrumental Activities of Daily Living Scale and Rivermead Motor Assessment for outcome assessment. This trial was registered with ClinicalTrials.gov (NCT03830372).

RESULTS

We assessed 60 patients and randomly assigned to the VR or control group. The VR group showed a significant reduction in depressive symptoms (ηp² = 0.13, p < 0.01) compared to SAT. The applied VR therapy significantly increased the sense of self-efficacy and the level of acceptance of the illness; however, this effect was similar to that obtained with the standard intervention. We did not observe statistically significant changes in the functional parameters of post-stroke patients.

CONCLUSION

The use of VR therapy combined with neurological rehabilitation had a positive effect on improving mood and reducing depressive symptoms in post-stroke patients.

Predictors of Post-Stroke Depression: A Retrospective Cohort Study

Despite reports of a high incidence and various predictors of post-stroke depression (PSD), the underdiagnosis and undertreatment rates of PSD are still high. This study aimed to examine the incidence of depression in stroke patients and identify factors associated with PSD. This was a retrospective cohort study on ischemic stroke patients from the Geisinger Neuroscience Ischemic Stroke (GNSIS) registry. The following statistical analyses were performed to predict PSD in the studied population: a Kaplan−Meier estimator and a Cox proportional hazards model. A total of 5882 patients were included in the study. The median age at the time of an ischemic stroke was 72 years and 56% were males. A total of 294 patients were diagnosed with PSD within one year of a stroke. The cumulative incidence of depression was found to be 6.4% (95% CI 5.7−7.1%) at one year for the entire cohort. Women were found to have a higher risk of PSD than men (HR for women = 1.47, 95% CI 1.18−1.85, p = 0.001). A history of prior stroke (HR = 1.58, 95% CI 1.18−2.11, p = 0.002) and myocardial infarction (HR = 1.47, 95% CI 1.05−2.06, p = 0.025) were associated with PSD. Medicaid patients had a higher risk for PSD (HR = 2.16, 95% CI 1.5−3.12, p < 0.001) than those with commercial insurance or health maintenance organization plans. Our findings showed that women, patients with a history of prior stroke or myocardial infarction, and with Medicaid insurance were more likely to develop PSD. Through an observational study on the EHR data, we confirmed that chronic stress, including financial and health-related stress, irrespective of age, significantly increased the risk for PSD.

The Usefulness and Clinical Characteristics of Antidepressant Use for Stroke Patients with Rehabilitation Program: An Exploratory Analysis

Objective

There has been a lack of data regarding the usefulness and clinical characteristic between patients-treated with and without antidepressants (Pw/Pwo ADs).

Methods

One hundred and eighty inpatients were recruited and observed for a 6-month. The depressive, cognitive, daily activity, and motor symptoms were evaluated at baseline and tracked at month 6, with the use of rating scales including Beck Depression Inventory (BDI), Mini Mental State Examination (MMSE), Global Deterioration Scale (GDS), modified Rankin Scale (MRS), modified Barthel Index (MBI), and Berg Balance Scale (BBS).

Results

Among 178 patients, 84 (47.2%) were treated with ADs. PwAD had numerically or significantly higher depressive cognitive, and motor symptoms along with daily activity impairment (8.3 point higher in BDI score, p < 0.001; 3.6 point lower in MMSE, p = 0.003; 0.8 point higher in GDS score, p = nonsignificant; 8.2 point lower in BBS score, p = 0.053, and 0.4 point higher in MBI score, p = nonsignificant) than PwoAD. Psychiatric consultation was also significantly higher in PwAD than in PwoAD (p < 0.001). The numbers need to treat for good clinical outcomes between PwAD and PwoAD were 5.8, 6.0, and 7.5, respectively, by MRS, MBI, and BBS scores.

Conclusion

Our findings suggest the potential utility of AD treatment and different clinical parameters between patients-treated with and without ADs. Adequately-powered and well-controlled further studies are mandatory to confirm and fully elaborate such association.

Needs and rights awareness of stroke survivors and caregivers in urban and rural China: a cross-sectional, multiple-centre questionnaire survey

OBJECTIVES

Stroke survivors require assistance and support in their daily lives. This survey aims to investigate the needs and rights awareness in Chinese stroke survivors and caregivers in rural and urban settings.

SETTING

This survey was adapted from the one created by the World Stroke Organization. The questionnaire included demands for psychological support, treatment and care, social support and information. From January 2015 to January 2016, the survey was pilot tested with urban and rural-dwelling stroke survivors and caregivers from 12 hospitals. Stroke survivors were invited to participate if they were over 18 years old and had experienced a stroke. Exclusion criteria were patients who had disorders of consciousness, significant cognitive impairment, aphasia, communication difficulties or psychiatric disorders. Only caregivers who were family members of the patients were chosen. Paid caregivers were excluded.

PARTICIPANTS

One thousand, one hundred and sixty-seven stroke survivors and 1119 caregivers were enrolled.

PRIMARY OUTCOME MEASURES

The needs of stroke survivors and caregivers in rural and urban areas were compared. The correlations between needs of rural and urban stroke survivors and caregivers and potential effect factors were analysed, respectively.

RESULTS

Among the cohort, 93.5% reported the need for psychological support, 88.6% for treatment and care, 84.8% for information and 62.7% for social support. The total needs and each aspect of needs of stroke survivors in urban settings were greater than of those in rural settings (p<0.01). In rural areas, total needs and each aspect of needs were positively correlated with education level (p<0.01).

CONCLUSIONS

Needs and rights awareness of stroke survivors should also be recognised in both urban and rural China. According to the different needs of patients and their caregivers, regional and individualised services were needed by stroke survivors and their caregivers.

Does depression after stroke negatively influence physical disability? A systematic review and meta-analysis of longitudinal studies

BACKGROUND

Depression after stroke is common and has been proposed to negatively affect disability by preventing optimal physical rehabilitation and recovery. However, the nature of this influence remains poorly understood. Here, we synthesise longitudinal studies to examine the hypotheses that depression after stroke (i) hampers physical rehabilitation, (ii) prevents functional improvement during recovery, and (iii) is associated with poor functional outcomes.

METHODS

A systematic literature search was conducted using the databases PubMed and Web of Science. A total of 5672 studies were screened; 28 met criteria for inclusion. The quality of included studies was assessed using the Newcastle-Ottawa Scale.

RESULTS

Individual studies showed no consistent effects of depression post-stroke on (i) the effectiveness of physical rehabilitation and (ii) functional improvements during recovery. In contrast, random-effects models revealed that (iii) depression after stroke was associated with an increased risk for poor long-term disability (OR: 2.16, 95% CI 1.70-2.77). Overall, the quality of studies was moderate and there was evidence for publication bias.

LIMITATIONS

The number of included studies was small. There was considerable methodological heterogeneity between studies, prohibiting meta-analyses for all effects of interest. Few studies examined the influence of antidepressants.

CONCLUSIONS

Depressed stroke patients are generally more disabled. However, depressed mood might not restrict improvements in physical disability during rehabilitation and recovery, although it seems to be linked to a delayed increase in the risk of poor functional outcome. High-quality evidence from longitudinal studies is needed to clarify the precise mechanisms and temporal dynamics underlying these associations.

The role of biopsychosocial factors in the rehabilitation process of individuals with a stroke

BACKGROUND:

A large proportion of individuals with a stroke are unable to return to work, although figures vary greatly. Due to the very high cost of post-stroke care, both tangible and intangible, in the form of long-term social consequences, it seems extremely important to search for factors responsible for the low efficiency of the rehabilitation and recovery process, because this fact has direct influence on future employment. Such knowledge would enable physiotherapists to quickly identify those patients who are at risk of rehabilitation breakdown, in order to provide them with special care and include them in intensive therapeutic treatments.

OBJECTIVE:

The aim of the study was to assess the efficacy of post-stroke rehabilitation, evaluated within the biopsychosocial aspect.

METHODS:

The study consisted of 120 patients after first stroke, including 48 women and 72 men aged 58.0 (±8.6). The measure of the effects of physiotherapy in the present study was not only the improvement of the functional state (simple and complex activities of daily life, locomotive activities), but also the improvement of the mental state (mood and the sense of well-being, level of acceptance of illness, perceived self-efficacy) and the reduction of pain. The Mini-Mental State Examination, the Geriatric Depression Scale, the Generalized Self-Efficacy Scale, the Acceptance of Illness Scale, the Visual Analogue Scale, the Barthel Index, the Instrumental Activity of Daily Living and the Rivermead Mobility Index were used. All parameters were measured twice: on admission to the ward and after three weeks of physiotherapy. The characteristics of the study group were presented using descriptive statistics. The analysis of interdependence of the efficacy of physiotherapy used two non-parametric tests: the Mann-Whitney U test to compare two groups, and the Kruskal-Wallis ANOVA test to compare a greater number of groups. Correlations between characteristics with continuous distributions were assessed using Spearman’s rank correlation coefficient (ρ), and in case of categorical variables, Pearson’s chi-squared (χ²) correlation coefficient. Linear regression was used to determine the hierarchy of the influence of particular characteristics on the efficacy of physiotherapy.

RESULTS:

Statistical analyzes show that patient’s age, time since stroke, number of comorbidities, family care capacity, marital status of the patient and also a low level of acceptance of illness, depression symptoms and lack of a sense of self-efficacy were related with low efficacy of post-stroke rehabilitation

CONCLUSIONS:

Comprehensive neurological rehabilitation, taking into account mental challenges and socio-economic circumstances of individuals with a stroke is essential in order to achieve high efficacy of physiotherapy. Important external factors may play a pivotal role in returning to work as well and should be taken into account during rehabilitation. Of interest should be to assess more biopsychological factors, such as acceptance of illness and a sense of self-efficacy referred to as barriers to return to work.

Rates and Correlations of Psychiatric Drug Administration in a Rehabilitation Center

Background:

Physical injury has been associated with the development of several psychopathological manifestations. Less is known about the use of psychiatric medication in those patients.

Objectives:

This study aimed to explore the use of psychiatric medication by patients been admitted in a rehabilitation center in a tertiary care teaching hospital and to inquire for the correlations of such drug administration.

Materials and Methods:

The sample consisted of 127 patients who had been admitted to a rehabilitation center, being in the postacute phase of their condition during a 2-year period. Patients’ medical records were searched for the demographic and clinical information.

Results:

Analysis was performed for 118 patients, mostly men (62.7%) with the mean age of 57.5 years. About 43.2% of patients (n = 51) were referred for psychiatric consultation, and 39.8% (n = 47) were prescribed a psychiatric drug. Traumatic brain injury was the diagnosis, positively correlated to referral. Twenty-seven out of the 67 nonreferred patients (40.3%) were prescribed psychiatric regimens by physicians. Nearly 38.1% of patients were diagnosed with a psychiatric disorder by the consultation-Liaison psychiatric service.

Conclusions:

In a rehabilitation center, psychiatric drug administration is common practice and drugs may be prescribed by the center's physicians and by psychiatrists. Such a drug prescription was found to be correlated to referral to the consultation-Liaison psychiatric service.

Needs and rights awareness of stroke survivors and caregivers: a cross-sectional, single-centre questionnaire survey

OBJECTIVES

The needs and rights awareness of stroke survivors have not been reported in China. This study investigated the needs and rights awareness of stroke survivors and caregivers in Tianjin, China.

SETTING

A survey launched by the World Stroke Organization was conducted in Tianjin, China. The questionnaire included demands for psychological support, treatment and care, social support and information. Stroke survivors and their caregivers were interviewed face to face for the questionnaire. Between June 2014 and February 2015, stroke survivors were invited to participate if they were more than 18 years old and had experienced a stroke. Exclusion criteria were patients who had disorders of consciousness, significant cognitive impairment, aphasia, communication difficulties or psychiatric disorders. Only caregivers who were family members of the patients were chosen. Paid caregivers were excluded.

PARTICIPANTS

Two hundred and forty-eight stroke survivors and 212 caregivers were enrolled.

PRIMARY OUTCOME MEASURES

The correlations between levels of needs and potential effect factors were analysed. Levels of different needs were compared by age, gender and time since stroke.

RESULTS

Among the cohort, 95.6% stroke survivors and 92.5% caregivers agreed to each question in the questionnaire. The participants prioritised the needs for psychological support (99.4%), treatment and care (98.6%), social support (98%) and information (96.2%). The total score was negatively correlated with age (r=-0.255, p<0.01). Patients below 65 years old had higher scores than those 65 years or older (p<0.01), while male patients had higher scores than female patients (p<0.01).

CONCLUSIONS

The needs for psychological and emotional support, individual treatment, social support and information about stroke were eagerly reported by most survivors. The Bill of Rights must be recognised by the Chinese society, providing appropriate stroke care to every patient to optimise stroke outcomes.

The Association between Post-Stroke Depression and the Activities of Daily Living/Gait Balance in Patients with First-Onset Stroke Patients

This study evaluated the association between post-stroke depression (PSD) and clinical outcomes, including activities of daily living (ADL) and gait balance, in patients with first-onset stroke. One hundred and eighty inpatients were recruited and followed-up for a 6-month. The depressive, cognitive, and stroke symptoms were assessed using the Beck Depression Inventory (BDI), the Global Deterioration Scale (GDS), the modified Rankin Scale (MRS), and the Berg Balance Scale (BBS). All patients were assessed at baseline and at the end of the observation (6-month). Among 180 patients, 127 (70.6%) were diagnosed with minimal-to-mild depression (MMD) while 53 (29.4%) were diagnosed with moderate-to-severe depression (MSD). The odd ratio (OR) for poor outcome in the MSD group was approximately 3.7 relative to the MMD group. The proportion of patients with better balance classified by the BBS score at 6-month was significantly higher in the MMD group than in the MSD group (OR=1.375). Our findings demonstrate the potential relationship between PSD and rehabilitation outcomes measured by different rating scales in Korean stroke patients. Our study suggests that clinicians should carefully evaluate depressive symptoms in patients with stroke during routine clinical practice. Adequately-powered and well-controlled further studies are necessary to confirm and fully characterize this relationship.

[The modern approaches to the prognostication of rehabilitation of the patients after stroke on an individual basis: a review of the literature and the results of original investigations]

This article was designed to analyze the results of the investigations with the purpose of elucidation of the prognostic factors relevant to the rehabilitation of the patients who survived after stroke. Special attention is given to the role of demographic (age and sex) factors and the data of the clinical, neurological, psychological, cognitive, and instrumental examination of the patients. The results of the original studies based on the treatment of 203 stroke patients are discussed in the context of modern concepts of the significance of the factors contributing to the recovery of the patients in the course of the post-stroke rehabilitation. The prognostic value of the selected factors, such as leukoareosis (for the patients presenting with hemorrhagic stroke), has been demonstrated for the first time. The new data on the duration of the rehabilitation period are presented with reference to its dependence on the type of stroke and localization of the lesions. Specifically, it is estimated to be 2 years for the patients who suffered from ischemic stroke in the brain stem, 31 months for those with ischemic stroke of the hemispherical localization, and 38 months for the patients presenting with hemorrhagic stroke (hemispherical hematoma). In addition, the data on the magnitude of the post-ischemic atrophic changes of prognostic values are presented.

Study on the behavioral changes of a post-stroke depression rat model

The aim of this study was to observe the changes in the levels of learning and memory in a post-stroke depression (PSD) rat model. Forty-eight Wistar rats were randomly divided into three groups: Group A (normal group), group B (stroke group) and group C (PSD group). Each group comprised 16 rats. Three and 7 days after successful modeling, the open-field, sucrose solution consumption and forced swimming tests were performed, so as to evaluate behavioral changes in the three groups of rats. The sucrose solution consumption of the rats in group B was lower than that in group A in the tests at the two time-points, but only the difference after 7 days was statistically significant (P<0.05). The sucrose solution consumption of the rats in group C was lower than the consumption of those in groups A and B, and the differences were statistically significant (P<0.05). The open-field test results showed that the horizontal and vertical activity scores of the rats in group B were significantly lower than those of the rats in group A (P<0.05). Furthermore, the two test levels and the vertical activity scores of the rats in group C were significantly lower than those of the rats in groups A and B (P<0.05). The immobility time of the rats in the forced swimming test was higher in group B than that in group A at the two time-points, but the difference was only statistically significant after 7 days (P<0.05). The immobility time of the rats in group C was significantly higher than that in groups A and B (P<0.01). In conclusion, rats with PSD exhibited a significantly reduced memory capacity and altered behavior. The changes in the PSD rats were more severe than those in the rats in the stroke group.
