Brief Summary
Acquired brain damage patients usually show severe cognitive deficit that alter their performance on every day life activities. Some of them suffer anosognosia and they are not aware of their own limitations. This situation increases disability by producing a large number of unsafe behaviours, caregivers burn-out and impede rehabilitation by affecting patients desire to follow treatment instructions. From disciplines like Neuropsychology, Cognitive Neuroscience or Occupational Therapy, it is considered a crucial issue to investigate the cognitive and neural mechanisms responsible of anosognosia, as well as to increase our knowledge about the most efficient treatments to deal with this phenomenon. The main general objective of this project is to generate and validate a detailed cognitive assessment protocol within the context of ADL to evaluate the different cognitive components of consciousness proposed on the Toglia and Kirk´s model: 1) Offline componente: metacognitive knowledge and 2) Online component: emergent awareness, self-regulation, anticipatory awareness, self-evaluation and updating processes).

Outcome Measures
Primary Outcomes (2)
The awareness ADL
Participants will be asked to do activities of daily living such as preparing a breakfast or dressing in which measures that evaluate components of anosognosia will be used. In the tasks of ADL conflict situations (and standardized solutions previously defined) and distractor objects will be presented. The total errors committed will be analyzed, as well as those committed only by conflict situations and distractor objects. The percentage of errors detected and corrected errors will be calculated. In addition, anticipatory awareness, self-evaluation and updating processes will be examined.
30-45 minutes
The Cog-Awareness ADL Scale
For the aim of this study, the Cog-Awareness ADL Scale, will have two versions, one to be administered to a direct caregiver and the other to the patient to observe the discrepancy index in relation to functionality-cognition. This tool allow to evaluate eight key cognitive abilities-task: manipulation difficulties, action schema, distraction, substitution, repetition, error detection, problem solving and task self-initiation in the two basic ADL and in the two instrumental ADL (BADL and IADL, respectively) (34 items). Both patients and caregivers must answer how often the patients present this cognitive-functional error in each of the 4 ADLs: 1: never, 2: sometimes, 3: quite often and 4: always. Two indices are calculated, one for BADL and one for IADL, adding all the scores of the two activities of each category among the number of activities answered. Lower punctuation is interpreted with worse results. There are 3 items that your scores should be reversed.

Study Arms (3)
Acquired Brain Injury group with anosognosia
People with presence of an acquired brain damage and cognitive deficits relative to executive functions and memory. To determine the presence of anosognosia, patients must present an overestimation value of their capacities greater than 5 (\>5) in the discrepancy index on the Patient Competency Rating Scale (PCRS) (Prigatano et al., 1998).
Acquired Brain Injury group without anosognosia
People with presence of an acquired brain damage and cognitive deficits relative to executive functions and memory. These patients must present a score of \< 5 on the PCRS Scale.
Control group
Healthy participants matched in age, gender and educational level with the others two groups.
Interventions
The participants will be evaluated with a set of tools within the context of meaningful ADL.
Eligibility Criteria
Acquired brain damage patients will be recruited on the collaborating hospitals and on different acquired brain damage organisations. Both, patients and control subjects, will be recruited from Málaga and Granada.
You may qualify if:
- Presence of an acquired brain damage objectively observed with medical reports.
- Cognitive deficits relative to executive functions and/or memory evaluated by the team of professionals who recruit participants in the hospital.
You may not qualify if:
- Presence of a serious visuoperceptual deficit that makes it difficult to complete the ADL tasks, evaluated by the team of professionals who recruit participants in the hospital.
- Presence of an understanding deficit (aphasia) evaluated by the team of professionals who recruit participants in the hospital.
- Presence of spatial neglect evaluated with line cancellation and line bisection tests.
- Presence of motor deficits in both upper limbs that impedes to complete the ADL tasks.
- Total score in MMSE\<18
