Assessment of Mendelian and risk-factor genes in Alzheimer disease: A prospective nationwide clinical utility study and recommendations for genetic screening.

Purpose: To assess the likely pathogenic/pathogenic (LP/P) variants rates in Mendelian dementia genes and the moderate-to-strong risk factors rates in patients with Alzheimer disease (AD).

Methods: We included 700 patients in a prospective study and performed exome sequencing. A panel of 28 Mendelian and 6 risk-factor genes was interpreted and returned to patients.

The relationship between semantic and episodic memory: evidence from a case of severe anterograde amnesia.

It is increasingly being recognized that new declarative, consciously accessible information can be learned in anterograde amnesia, but it is not clear whether this learning is supported by episodic or semantic memory. We report a case of a 55-year-old man who experienced severe amnesia after limited damage to the medial temporal lobe following neurosurgical complications. His general cognitive performance and knowledge of new French words and public events that occurred before and after the onset of amnesia were assessed.

Empowering general practitioners in dementia care: The ANTISTIGMA education intervention in Europe.

Background: There is a well-documented lack or delay of diagnosis of dementia in all countries, including in Europe. Most general practitioners (GPs) have acquired adequate academic and scientific information about dementia but avoid using it in practice because of stigma.

Objectives: To persuade GPs of their role in dementia detection, an Antistigma education intervention was designed, with teaching objectives focusing on "Why" and "How" to diagnosis and manage dementia, based on ethical and practical content, as opposed to classical training centered on teaching "What", with mainly academic content.

Phenotype and imaging features associated with APP duplications.

Background: APP duplication is a rare genetic cause of Alzheimer disease and cerebral amyloid angiopathy (CAA). We aimed to evaluate the phenotypes of APP duplications carriers.

Methods: Clinical, radiological, and neuropathological features of 43 APP duplication carriers from 24 French families were retrospectively analyzed, and MRI features and cerebrospinal fluid (CSF) biomarkers were compared to 40 APP-negative CAA controls.

Describing perceived stigma against Alzheimer's disease in a general population in France: the STIG-MA survey.

Background: Alzheimer's disease (AD) causes progressive loss of memory and disability, especially in older people. As worldwide population grows older, AD is responsible for an important social and economical burden in many nations. People suffering from AD may experience health-related stigma that influences their attitudes towards seeking assistance.

Seizures in the elderly: development and validation of a diagnostic algorithm.

Seizures are frequent in the elderly, but their diagnosis can be challenging. The objective of this work was to develop and validate an expert-based algorithm for the diagnosis of seizures in elderly people. A multidisciplinary group of neurologists and geriatricians developed a diagnostic algorithm using a combination of selected clinical, electroencephalographical and radiological criteria.
