Introduction: Symptoms of psychosis, characterized by delusions and hallucinations, are commonly experienced by persons living with dementia. A systematic review was completed to identify tools to evaluate symptoms of psychosis compared to a reference standard in persons with dementia. Articles reporting correlation values between psychosis tools were also identified.
Methods: The search concepts psychosis, dementia, and diagnostic accuracy were used to search MEDLINE, PsycINFO, and Embase. Included articles meeting the primary objective described a tool to assess symptoms of psychosis, delusions, or hallucinations in persons with dementia, a reference standard form of diagnostic assessment for psychosis, and diagnostic accuracy outcomes for the psychosis tool. Secondary objective articles reported correlation values between two or more psychosis tools in persons with dementia.
Results: One study met the primary objective and described the sensitivity and specificity of the Neuropsychiatric Inventory (NPI) and Columbia University Scale for Psychopathology in Alzheimer's Disease (CUSPAD) in identifying symptoms of psychosis, hallucinations, and delusions. The sensitivity of the NPI and CUSPAD in identifying symptoms of psychosis was 83 and 90%, respectively. Nine studies meeting the secondary objective described eleven unique tools and examined the degree to which tools used to assess psychotic symptoms in persons with dementia were related.
Discussion: The NPI and CUSPAD were identified in a single study as psychosis tools that have been evaluated against a reference standard of psychosis assessment in persons with dementia. Various tools to assess the burden of psychotic symptoms in persons with dementia exist, but the diagnostic accuracy of existing tools remains understudied. Further research on the comparative utility and diagnostic accuracy is required for all psychosis tools used with persons with dementia.

Despite the growing deployment of the Montessori method in nursing homes, there is no instrument to measure its implementation fidelity, limiting the interpretation of results. Our aims are to i) develop an evaluation grid for the Montessori method in nursing homes; ii) explore its sensitivity to practice heterogeneity among institutions pre-training; and iii) study its sensitivity to change after the training. Based on literature and expert opinions, we created an evaluation grid.

People suffering from a neurodegenerative disease, at a stage still allowing physical activity, encounter more difficulties to access to re-education and rehabilitation care. A trial unit specialized in medical care and rehabilitation (SMR) was created to handle these patients, who suffered a morbid intercurrent event not related to the neurocognitive disorder. The trial unit was created thanks to a dedicated funding from the Brittany Health Regional Agency (ARS) following-up a call for projects in October 2021.

Odors are known to entertain a special link with memory: once the meaning of an odor has been learned, it naturally acts as a retrieval cue of the learning context, along with the emotions and behaviors associated with it. The existence of this link has for several years inspired the study of olfactory function in Alzheimer's disease (AD), known for the memory disorders it causes. The aim of this review is to summarize the current scientific knowledge on the almost paradoxical dual role played by odors in the management of AD, as both screening and therapeutic tools.

Background: Age-related hearing loss and mild cognitive impairment (MCI) independently increase dementia risk. The Ageing and Cognitive Health Evaluation in Elders randomised controlled trial (RCT) found hearing aids reduce cognitive decline in high-risk older adults with poor hearing.
Methods: This pilot RCT in London memory clinics randomised people with MCI (aged ≥55, untreated hearing loss defined as Pure Tone Average 0.

Objectives: This scoping review aims to map out the coping strategies among Persons with Mild Cognitive Impairment (PwMCI) and Persons with Mild Dementia (PwMD), identifying the facilitators and the barriers to the use of the strategies.
Method: We conducted a systematic search of peer-reviewed studies in PubMed, CINAHL, EMBASE, and PsycINFO. Under the guidance of the Coping Circumflex Model, we identified coping strategies and then conducted thematic synthesis.
