Cognitive-functional Evaluation of Anosognosia

Status Completed

Clinical Trial 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).

Clinical Trial Description

The proposed protocol is composed by two ecological tools: The Cog-Awareness ADL Scale (ADL scale of metacognitive knowledge) and the Basic and Instrumental ADL performance based test (Awareness ADL), to identify the presence of cognitive deficits and anosognosia in patients with ABI always within the context of everyday life activities. One first specific aim is to test the convergent validity of the two proposed ecological tools with other traditional and validated measures usually used to assess similar cognitive processes and components of self-awareness. The second specific objective is to investigate the external validity of the ecological tools, by testing whether they are able to discriminate between acquired brain damage patients with and without anosognosia and a group of neurologically healthy participants on every component. After conducting a literature review of the subject we found that this would be the first protocol developed to identify all these components in the same study. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
