A systematic review of rehabilitation programs for cognitive impairment related to breast cancer: Different programs at different times?

BACKGROUND: "Cancer Related Cognitive Impairment" (CRCI) defines cognitive disorders related to cancer and its treatments. Many people with breast cancer experience signs of CRCI (incidence between 20 and 30 %) and, although several intervention options exist, there is no established standard of care. Our main objective was to provide a detailed description of the methods and results of randomized controlled trials of interventions for CRCI in breast cancer survivors, paying particular attention to the timing of the interventions within the care pathway. METHODS: We conducted a systematic literature review following the PRISMA guidelines from 01 to 01-2019 to 16-07-2023 and included randomized controlled trials of interventions for CRCI after breast cancer with at least one objective cognitive assessment as a primary or secondary outcome. RESULTS: Among 228 identified studies, 35 (including 2821 participants) were retained for inclusion. The interventions were classified into 4 categories: cognitive rehabilitation, physical activity, complementary therapy and pharmacological treatment. Our analysis revealed that pharmacological interventions have no effect, whereas physical activity interventions proposed in the months following the initial cancer treatment improve Quality of Life and Speed of Information Processing while interventions proposed later improve Memory and Attention (Cognitive Rehabilitation) and Perceived Cognitive Function and Depression/Anxiety/Mood (Complementary Therapies). CONCLUSION: CRCI is multifactorial and affected individuals frequently experience high levels of fatigue, pain, anxiety and depression and are most likely to benefit from holistic approaches that include cognition, physical activity, relaxation, psychoeducation, group support and/or psychological counselling. Thus, rehabilitation programs should be designed on multi-modal approaches, using innovative, cost-effective delivery methods that increase access to treatment, and intervention outcomes should be evaluated using measures of participation. DATABASE REGISTRATION: The review was recorded on Prospero (01-03-2020), with the registration number 135,627.

Description of an interdisciplinary, holistic cognitive rehabilitation program for adults with mild to moderate cognitive impairment after acquired brain injury.

PURPOSE: Cognitive rehabilitation research has progressed slowly, in part due to incomplete reporting of intervention content and delivery and the difficulties this produces for discerning program effectiveness. This knowledge gap can be reduced by providing detailed intervention descriptions. We document the content/ingredients and therapeutic targets of a cognitive rehabilitation program for adults with mild-to-moderate cognitive impairment. METHODS: The documentation process used a method of participatory/collaborative research. Discussions with the clinical team identified session content/ingredients and therapeutic targets, which were then described using Body Functions, and Activities & Participation domains from the International Classification of Function, Disability and Health (ICF). Domains most frequently targeted by each clinician were identified as Primary Targets. RESULTS: Each clinician produced a detailed description of session content, implementation, and ICF-coded therapeutic targets. This revealed that the whole program targets 29 ICF domains, seven of which were identified as Primary Targets: Higher-level Cognitive; Attention; Memory; Emotional; Global Psychosocial, Temperament and Personality, and Conversation. CONCLUSIONS: Documentation of treatment targets enabled identification of appropriate outcome measures which are now being used to investigate program efficacy. This step-by-step explanation of the documentation process could serve as a guide for other teams wanting to document their rehabilitation interventions and/or establish similar programs.IMPLICATIONS FOR REHABILITATIONIncomplete reporting of intervention content and delivery contributes to difficulties in discerning the effectiveness of complex rehabilitation programs.Current recommendations for rehabilitation intervention reporting suggest that these difficulties can be partially overcome by providing detailed descriptions of intervention content/ingredients and treatment targets.Human and physical resources differ widely from one clinical setting to another and the existence of clear program descriptions can guide clinicians who wish to create similar programs.Detailed descriptions of rehabilitation interventions are necessary to accurately measure patient outcomes and generate testable hypotheses about proposed mechanisms of action.Program descriptions are needed for the development of treatment theories and the advancement of evidence-based practice in rehabilitation.

Caloric Vestibular Stimulation Reduces the DirectionalBias in Representational Neglect.

Caloric vestibular stimulation (CVS) can temporarily reduce visuospatial neglect and related symptoms. The present study examined the effect of CVS on representational neglect during free exploration of the map of France. We asked patients to name cities they could mentally "see" on the map of France, without giving them any directional instructions related to the left or right sides of the map. In right brain damaged patients with left visuospatial neglect, the mental representation of the map was asymmetrical (favoring the right side). After stimulation, neglect patients named more towns on the left side of the map, leading to a significant reduction in map representation asymmetry. Our findings are consistent with previous studies on visuospatial neglect and are in favor of a central effect of vestibular stimulation on mechanisms involved in space representation.
