The aim of this study is to propose a non-anxiety-inducing method of managing behavioral disorders for patients and healthcare professionals. The main objective of this study is to evaluate the implementation, use and effects of HAPNeSS (Hypnosis Adapted to People with Severe Neurocognitive Disorders) training on the management of residents aged over 75 with moderately severe to severe Alzheimer's disease or a related disorder, who may present behavioral disorders, with caregivers working in EHPAD.

The HAPNeSS method would offer caregivers the opportunity to find solutions to difficulties encountered (behavioral disorders, difficult care, etc.), to move away from pure technicality to reinvest in the relationship with the patient, and to find soothing, respectful and benevolent channels of communication. The aim of this study is to evaluate the effects of HAPNeSS (Hypnosis Adapted to People with Severe Neurocognitive Disorders) training on the care of residents over 75 with moderately severe to severe Alzheimer's disease or related disorders, who may present behavioral problems.

But also to measure, within each establishment, the effects of the HAPNeSS method, on the professional practices of caregivers (actions implemented, execution of missions, relationship with residents...) and to gather their feelings. These objectives therefore aim to collect and evaluate the effects of this method on the relationship between patients and caregivers, as well as on the latter's QWL. To achieve this, the research team organized 4 visits to the EHPADs participating in the study, spread over 6 months. Training takes place over 3 and then 2 days. Before and after the training, a visit at the beginning and end of the study will enable the scales to be administered and the interviews to be conducted. The data collected will be the subject of a mixed statistical analysis. Throughout the study, the research team will monitor the learning and development of each care professional.
