Assessing Cognitive Outcomes in Coma Survivors: A Literature Review.

(1) Background: Although cognitive impairments in coma survivors are common, methods of measuring long-term cognitive outcomes in this population are inconsistent, precluding the development of a strong evidence-base to support clinical decision making. In this literature review, we identify and characterize the measures used to track cognitive recovery in coma survivors to data. (2) Methods: We extracted the instrument used for cognitive assessment, the cognitive domains assessed, methods administration and scoring, and timing of assessment from 134 of 996 screened records. (3) Results: A total of 133 unique cognitive tests and cognitive testing batteries were identified, with 97 cognitive instruments used in less than three articles. The instruments assessed 20 different cognitive domains, with 73 articles also using tests that assess general "cognitive ability". Cognitive instruments ranged from subjective assessments to comprehensive cognitive batteries. There were inconsistent points of reference for the timing of assessment across studies, with few studies repeating assessments at more than one time point, and arbitrary time intervals between tests. (4) Conclusions: Overall, this review illustrates the enormous disparity between studies that track cognitive outcome in coma survivors, and the need for a systematic, patient-accessible method of assessing cognitive functioning in future studies with this population.

Enacting agency: movement, dementia, and interaction.

BACKGROUND: Arts-based programs can counter the dominant narrative of loss associated with dementia, in part through fostering expressions of agency. This study uses social science theories of interaction between structure and agency to examine how an arts-based movement program, entitled Mouvement de passage, supports agency among individuals with dementia. METHODS: Ethnographic methods were used to trace how participants enact agency within the structure of the movement program. The program's sessions were video recorded and iteratively analyzed. RESULTS: Participants expressed their agency in three ways: 1) transforming the exercise's structure according to individual interests and desires; 2) resisting the exercise's structure; and 3) improvising movements collectively. CONCLUSIONS: The movements of individuals with dementia were shaped by both program structure and individual/collective expressions of agency. The design of Mouvement de passage, based on open-ended structures and voluntary participation, provides a template for developing interventions that foster agency among these persons.

Mouvement de passage: Creating connections through movement among persons with dementia.

One of the challenging consequences of dementia is the change in relationships that can co-occur with the progression of this condition. Despite this well-documented change, few arts-based interventions target the relational dimension of dementia. This study aims to explore the effects of one arts-based relational intervention: a movement program designed to foster connections within a group of persons with dementia. We used ethnographic methods-including participant observations and informal interviews-to understand the relational effects of this program conducted by two dancers and a musician. The movement sessions were video recorded, and participant movement trajectories were analyzed for different ways in which they created connections. We identified two types of connections-nonreciprocal and reciprocal-and four subtypes of connections-connection to exercise/music, connection to participant, interpersonal connection, and group connection-that participants engaged in during the movement program. Despite most participants not remembering the previous movement sessions, they experienced increasing numbers of connections over the course of the program, particularly reciprocal interpersonal connections. Participants explored new forms of moving and creatively transformed the movement structures proposed by the dancers. The results demonstrate the effectiveness of this program in augmenting connections and fostering exploration and creativity in individuals with dementia, providing a template for further developments of interventions targeting the relational dimensions of dementia. This study also highlights the potential of combining ethnographic methods and video analysis to include the perspectives of persons with dementia in research.

Protocol for the Prognostication of Consciousness Recovery Following a Brain Injury.

Individuals who have suffered a severe brain injury typically require extensive hospitalization in intensive care units (ICUs), where critical treatment decisions are made to maximize their likelihood of recovering consciousness and cognitive function. These treatment decisions can be difficult when the neurological assessment of the patient is limited by unreliable behavioral responses. Reliable objective and quantifiable markers are lacking and there is both (1) a poor understanding of the mechanisms underlying the brain's ability to reconstitute consciousness and cognition after an injury and (2) the absence of a reliable and clinically feasible method of tracking cognitive recovery in ICU survivors. Our goal is to develop and validate a clinically relevant EEG paradigm that can inform the prognosis of unresponsive, brain-injured patients in the ICU. This protocol describes a study to develop a point-of-care system intended to accurately predict outcomes of unresponsive, brain-injured patients in the ICU. We will recruit 200 continuously-sedated brain-injured patients across five ICUs. Between 24 h and 7 days post-ICU admission, high-density EEG will be recorded from behaviorally unresponsive patients before, during and after a brief cessation of pharmacological sedation. Once patients have reached the waking stage, they will be asked to complete an abridged Cambridge Brain Sciences battery, a web-based series of neurocognitive tests. The test series will be repeated every day during acute admission (ICU, ward), or as often as possible given the constraints of ICU and ward care. Following discharge, patients will continue to complete the same test series on weekly, and then monthly basis, for up to 12 months following injury. Functional outcomes will also be assessed up to 12 months post-injury. We anticipate our findings will lead to an increased ability to identify patients, as soon as possible after their brain injury, who are most likely to survive, and to make accurate predictions about their long-term cognitive and functional outcome. In addition to providing critically needed support for clinical decision-making, this study has the potential to transform our understanding of key functional EEG networks associated with consciousness and cognition.
