1. Cognitive disorders at home: understanding the intervention context<\/h2>\n1.1 Profiles encountered and specificities of each pathology<\/h3>\nHome helpers and family caregivers face a wide spectrum of cognitive disorders, each with its own characteristics that directly influence the approaches to be used. Alzheimer’s disease<\/strong> \u2014 the most common \u2014 is characterized by early and progressive impairment of recent episodic memory, then semantic memory, with relative preservation of emotional and procedural memory until advanced stages. The person often lives in a subjective past time \u2014 their parents are still alive, their children are young, they need to go to work. This subjective reality is coherent for them, even if it is disconnected from the objective present.<\/pee>\nLewy body dementia<\/strong> presents a fluctuating profile with episodes of confusion alternating with periods of relative lucidity, frequent visual hallucinations, and severe sleep disturbances. Vascular dementia<\/strong> is more progressive and stable, often with specific deficits related to the affected brain areas. Frontotemporal dementia<\/strong> preferentially affects personality and social behavior before memory \u2014 producing disinhibited or apathetic behaviors that can be very disturbing for those around. Each profile requires specific adaptations of the approaches of validation, redirection, and anchors.<\/pee>\n\n\n 1.2 M<\/span>

These approaches are intuitively logical for intact brains \u2014 but they systematically fail with people presenting severe cognitive disorders.<\/pee>\nThe reason is neurobiological: in advanced dementia, the prefrontal cortex \u2014 which allows for the integration of contradictory information, updating beliefs, and accepting a logical correction \u2014 is severely affected. The person no longer has the cognitive ability to integrate information that contradicts their subjective reality. What they can do, however, is feel the emotion associated with the interaction: correction generates shame, anxiety, and agitation; validation generates calm, trust, and cooperation. Emotional memory \u2014 supported by the amygdala and subcortical circuits largely preserved until advanced stages \u2014 remains functional long after cognitive memory fails.<\/pee>\n\ud83e\udde0 Foundational principle:<\/strong> In supporting cognitive disorders, the subjective reality of the person is<\/em> their reality. It is not a mistake to be corrected \u2014 it is a lived experience that deserves to be welcomed with respect. Our role is not to bring the person back to our reality, but to join theirs to create a safe and caring interaction.<\/pee><\/div>\n2. Validation: joining the person’s reality<\/h2>\n\n\n
