Review Meta Analysis
[Awareness disorders in Alzheimer's disease and in mild cognitive impairment].
Awareness disorders in Alzheimer's disease still remains unclear despite much research regarding this phenomenon. Papers report various and contrasted results with varying frequency from one study to another. Hence, the interest in awareness in Alzheimer's disease remains limited. Nevertheless, this symptom is closely associated with caregivers' burden and increases the patient's dependency, since the patient is unable to avoid dangers, requiring some care services or institutionalization The purpose of this current review is to recall the main neuro-anatomical and theoretical basis of awareness disorders, and to highlight the recent findings in Alzheimer's disease and in its pre-clinical stages. ⋯ These controversial results are due to the heterogeneity of Alzheimer patients and in particular of MCI patients, but also to various conceptions of awareness disorders in Alzheimer's disease; none of them, however, taking into account all its diversity and complexity. Thus, neurological approaches underline neuropsychological dysfunctions linked to right frontal and/or hemispheric damage but are based on brain injury or strokes, which are events that differ greatly from a neurodegenerative disease involving progressive cognitive, emotional and social disturbances. Psychiatric approaches have taken into account the various aspects of insight, which before were often forbidden and reduced to a categorical point of view, and so could contribute to a better understanding of awareness disorders in Alzheimer's disease. However, these aspects have been conceptualized for psychiatric patients, suffering from positive symptoms, where compliance in treatment is the central key. Insight in neurological diseases is more focused on negative symptoms and generally concerns a basic perception of impairments in mainly cognitive domains. Moreover, modeling has often opposed neurological and psychological mechanisms, so awareness disorders are out of scope of a primary and secondary symptomatology. Although some authors have proposed to take into account these two mechanisms (unawareness and denial), clinical practice has shown that it was impossible to distinguish them both. Finally, some social cognitive approaches are able to demonstrate that there is no correlation between severity of dementia and awareness disorders. Nevertheless, the Self-concept, underlying this point of view, does not permit distinguishing neuropsychological from psycho-social factors. Moreover, only one evaluation tool based on Self-modeling in Alzheimer's disease exists, and to conceptualize Self in a specific pathology does not permit the comparison of this pathology to others or to healthy control subjects. So, the authors present the multidimensional model proposed by Clare et al., and some perspectives to stimulate future research, and perform potential meta-analyses.

Comparative Study
[Sexual dysfunction and depression: Validity of a French version of the ASEX scale].
Since the Beck study (1967), it is well known that sexual dysfunction is particularly prevalent in depressive patients compared to the general population, at 70% and 30% respectively. Depression, psychotropics and antidepressants are responsible for altering sexuality, and patients are considerably affected by these symptoms that dramatically decrease their quality of life. Screening for sexual dysfunctions seems essential, and a scale such as the Arizona Sexual Experience Scale (ASEX) may help practitioners. The English version of this scale was validated in 2000 (McGahuey et al. [9]), and is widely used in scientific research. The aim of this study was to assess the validity of the French version of the ASEX scale. ⋯ This study assessed the validity and reliability of the French version of the ASEX scale. These findings demonstrate the highly acceptable psychometric properties of ASEX in patients with depression.

The number of patients requiring primary and secondary care for factitious disorder unexplained by any known medical condition is high. We report a case illustrating the clinical and psychopathological features of factitious disorder. The treatment difficulties encountered in the association of this disorder with dermatillomania are discussed. ⋯ The comorbidity of factitious disorder and dermatillomania makes diagnosis very difficult. The limit between the two disorders is sometimes unclear.

Developing programs and actions to fight stigma and discrimination against people living with mental disorders is a priority both internationally and in France. Involving mental health service users in these anti-stigma programs has proved to be a key element for effective programs. The present study evaluates the impact of user-trainers in an anti-stigma campaign with job counselors on their knowledge, beliefs, and desire for social distance with regard to mental illness and the mentally ill. ⋯ A mental health awareness day using mental health service users and psychiatrists as trainers had significant positive effects in terms of reducing stigma with regard to people with mental illness. Further research is needed to understand whether the impact of such awareness approaches can be maintained in everyday professional practice over time.

The highest consumption levels of alcohol are found in the developed world, mostly the Northern Hemisphere. After a slight decrease at the beginning of the 1990s, alcohol use in the European Region increased with an average adult per capita consumption amounting to 12.5 litres of pure alcohol per capita for the year 2009. In France, adult consumption was 12.7 litres of pure alcohol per capita for the year 2009, and it is estimated that 1.5 to 2 million of adults are alcohol-dependent (4-5% of the adult population) and 5 million are excessive drinkers. ⋯ From 37 community-based psychiatric epidemiology studies that used standardized diagnostic instruments and included data on the percentage of individuals receiving care for alcohol abuse or dependence, the median rate of untreated cases of these disorders was calculated across the studies. Alcohol abuse and dependence had the widest treatment gap at 78.1% worldwide, and 92% in Europe. In this context, healthcare systems must adapt to meet the needs of patients who currently do not receive specialized care.
