Informal caregivers’ burden and stress in caring for stroke survivors with spatial neglect: an exploratory mixed-method study

Background: Spatial neglect prolongs stroke survivors’ recovery to independence. However, little is known about the impact of spatial neglect on caregivers of stroke survivors. Objective: To explore the factors associated with burden and stress among informal caregivers of stroke survivors with spatial neglect. Methods: Following the previous study of 108 stroke survivors, we reached 24 stroke survivors’ caregivers, and 20 caregivers (age: M±SD=56.9±12.7 years; 12 females) completed the study. 10 survivors had symptoms of spatial neglect, and 10 did not (i.e., SN+ or SN-, respectively) at the time when discharged from inpatient rehabilitation, which was 9.3±6.2 months before the present study. Via a semi-structured telephone interview, we assessed caregivers’ burden and stress qualitatively and quantitatively. Results: No difference was observed across caregiver groups in cognitive function, depressive mood, or community mobility. In comparison, caregivers of the SN+ group allocated more time to care, controlling for survivors’ disability (adjusted effective size d = 1.80). Their self-perceived burden and stress were more severe than the other group (adjusted d = .99). Qualitative analysis indicated caregivers of the SN+ group were more likely to describe economic stressors and undesirable changes in career and vacation planning. While 80% of participants preferred their care recipients to receive additional motor or mobility therapy, caregivers of the SN+ group were more likely to suggest additional therapy for cognitive impairment. Conclusions: This exploratory study suggests that spatial neglect may heighten caregivers’ burden and stress levels. Future studies with a large sample size are required.

Assessing chronic stroke survivors with aphasia sheds light on prevalence of spatial neglect

Background: Stroke is a chronic disease. Standardized assessment is essential in order to determine areas for treatment. Individuals with aphasia are often excluded from research, because it is believed that their language impairments may impact their ability to provide informed consent. Thus, right spatial neglect could be under-diagnosed. Objective: This study was developed to (1) determine the frequency of spatial neglect in chronic left-brain stroke survivors with aphasia, (2) determine the clinical utility of an aphasia-friendly consent form, and (3) determine any differences between neglect and no-neglect groups regarding activities of daily living (ADL) performance and community independence. Methods: Forty-six people were consented at community center. Three were screen failures secondary to the exclusion criteria. A novel, aphasia-friendly consent form was developed to facilitate participation of individuals with aphasia. This enabled 93% or 40 out of the 43 recruited participants to be included in this study. The Behavioral Inattention Test-conventional and the Catherine Bergego Scale via Kessler Foundation Neglect Assessment Process (CBS via KF-NAP) were utilized to determine neglect. The Life Space Questionnaire was used to determine community mobility and independence. The Barthel Index (BI) was used for objective clarification of performance in ADL. Results: Successful use of the consent form resulted in determination that five out of 40 (12.5%) met criteria for spatial neglect; (on the CBS via KF-NAP). The neglect group had lower scores on the Life Space, suggesting less community mobility and independence, however, it was not statistically significant (p = 0.16). Differences in BI scores were also not significant (p = .013) but the neglect group did have reduced independence. Conclusions: This study demonstrates the need to administer functional neglect assessments in left-brain stroke and to include individuals with aphasia in research.

The feasibility and effectiveness of using prism adaptation to treat motor and spatial dysfunction in stroke survivors with multiple incidents of stroke

ABSTRACT Background Strokes resulting in cognitive and motor problems can be debilitating and prolong recovery. Risk of a second stroke occurs for 40% of all first-time stroke survivors within five years. Prism adaptation treatment (PAT) may simultaneously improve functions of both spatial and motor systems. This has not been studied with a cohort comprised of multiple strokes nor measured change using specific motor outcomes. Objectives To determine the feasibility and effectiveness of using PAT to improve spatial and motor functions in stroke survivors with multiple strokes. Method A prospective intervention with retrospective comparison. Thirteen participants from an inpatient rehabilitation facility (IRF) comprised the treatment group; 13 others who only received standard care comprised the comparison group. Treatment group tested on: 4 motor and 3 spatial outcome measures before and after the 10 PAT sessions. The comparison group tested on: 1 motor and 3 spatial measures before and after standard care. Results Thirteen participants successfully completed the PAT. Both groups improved on measures of spatial neglect over time (p < .001), but the treatment group showed greater improvement on two subtests of spatial function (Behavior inattention test) (p = .001 & p = .002). Similarly, both groups improved in motor function (Functional independence measure) (p < .001), although the treatment group’s improvement was not statistically significant against the comparison group (p = .853). Conclusion PAT is a feasible treatment for stroke survivors with multiple strokes. PAT did improve spatial neglect function more than standard care, only at one level of analysis of standard paper and pencil measures. Further research is necessary.

Illustrating where spatial perception versus memory-based representation: spatial neglect in a distinguished artist; a case report

ABSTRACT Spatial neglect is a disorder of attention, perception, and processing of stimuli in contralesional space. The heterogeneous behaviors involve diverse neuroanatomical mechanisms. Anecdotal evidence suggests that neural circuitry of active spatial perception may differ from that used to encode spatial memory. These differences can escape detection by conventional assessments, thereby leading to missed diagnoses. We present a case, in an artist who demonstrates selective impairment in a contralesional space during active Where spatial perception. His performance is better when asked to draw entirely from memory. This case highlights the variability in neglect, importance for comprehensive testing, and encourages further investigation.

Comprehensive, technology-based, team approach for a patient with locked-in syndrome: A case report of improved function & quality of life

ABSTRACT One of the most severe types of stroke is locked-in syndrome (LIS) due to the loss of almost all voluntary motor functions and a high mortality rate. The majority of the literature regarding LIS is based on case reports that utilized multidisciplinary interventions focused on improving functional communication and respiratory care with minimal focus on motor retraining. These reports were neither dynamic nor multi-sensory, and the only technology utilized was in the form of augmentative communication. There are additional types of technology frequently used in the general stroke population that can address similar motor deficits that occur in the LIS population. This case report explains an interdisciplinary approach using motor and communication interventions that are multisensory, progressive, multi-modal, and technology- based. The length of stay was 153 days in acute rehabilitation, after which the patient returned home making significant gains in overall function. In this patient, the FIM changes in motor (+42), cognitive (+29) and total change score of (+71) surpassed what was determined to be a minimal clinically important difference. These results suggest that this treatment program and approach may be a key reason why this patient was able to achieve significant functional gains and report improved quality of life.
