Since psychiatric institutions began discharging mentally ill patients into the community, family of patients suffering from schizophrenia are more and more involved in the therapeutic process. The adverse consequences of having a patient suffering from schizophrenia at home are called "burden of care" and have been studied by numerous authors. We were interested in the quality of life of caregivers and its evaluation. This concept represents a more complex, multidimensional approach in which many variables are taken into account. We propose the development of a French self-administered instrument of quality of life for caregivers of individuals with schizophrenia, the caregiver schizophrenia quality of life questionnaire (S-CGQoL). ⋯ The S-CGQoL is the first self-administered quality of life questionnaire for caregivers of patients suffering from schizophrenia. It presents satisfactory psychometric properties, which can be completed in five minutes and, therefore, fulfils the goal of brevity sought in research and clinical practice.

Review Comparative Study
[Psychomotor agitation, pharmaceutical sedation and psychiatric emergency in psychotic patients].
Psychomotor agitation, very common among psychiatric emergencies, raises the question of pharmaceutical sedation, its indications, and its issues, notably with regard to the observance in postemergency. A new approach to sedation places it within its therapeutic aim and also takes into account the sometimes harmful impact on the course of the patient's care. A pretherapeutical, analysis both clinical and environmental is crucial. ⋯ The use of atypical antipsychotics and injectable forms is argued. Early psychical sedation is preferable to the obsolete practice of vigilance sedation and to behavioural sedation with its limited indications. The use of excessive or prolonged sedation might have a detrimental effect on the care offered after psychiatric emergency treatment.

Abnormalities involving the prefrontal cortex (PFC) have long been postulated to underpin the pathophysiology of schizophrenia. Investigations of PFC integrity have focused mainly on the dorsolateral PFC (DLPFC) and abnormalities in this region have been extensively documented. However, defects in schizophrenia may extend to other prefrontal regions, including the ventromedial PFC (VMPFC), and evidence of VMPFC abnormalities comes from neuropathological, structural and functional studies. ⋯ Thus, further research should assess decision-making in schizophrenia by testing a large group of patients with homogeneity of diagnostic, in comparison with a large group of control subjects. Authors should control for IQ or level of education, substance use disorder and smoking status. While it is now accepted that DLPFC defects in schizophrenia may extend to VMPFC, future investigations should test for an association between memory, insight ability and IGT performance and assess the impact of antipsychotic dosage upon performance.

The co-occurrence between post-traumatic symptoms and psychotic symptoms is well described in the immediate suites of a trauma but can also be chronic. This symptomatic co-occurrence, rarely studied in the literature, is often approached under the sole angle of a primary post-traumatic stress disorder (PTSD) or of a primary psychosis, without federative will to unify the psychotic and post-traumatic symptoms within the same nosological framework. Individuals with schizophrenia or schizoaffective disorder report higher rates of trauma and assault than the general population. ⋯ The links between psychotic and psycho-traumatic symptoms are complex and multidirectional; this co-occurrence is a factor of seriousness. The clinician, while paying attention to these symptoms, has to distinguish the structure of the personality of the subject to articulate the psychotherapy and the pharmacological treatment. Further investigational studies may determine whether antipsychotics will enhance treatment response in PTSD patients with psychotic features.

Charles-Bonnet syndrome (CBS) is conventionally defined by the presence of visual hallucinations in patients suffering from lowered visual acuity without having psychosis or dementia. Actually, it is a syndrome that interests many specialties, especially ophthalmology, geriatrics, neurology and psychiatry. "Atypical CBS" or "CBS plus" was introduced to designate any kind of visual hallucinations that could be considered as a CBS but accompanied by a low level of insight, a possible cognitive decline, other hallucinatory modalities etc. Since all patients suffering from CBS have to be psychiatrically evaluated, psychological and psychiatric implications of their syndrome have to be well understood in order to better manage them. These psychiatric and psychological implications are: the relationship between the CBS and dementia, the psychological reaction of the patients towards their hallucinations and psychiatric comorbidities that could be developed during the course of the syndrome. ⋯ Atypical CBS is a syndrome that could be eventually associated with dementia, accompanied with a major depressive disorder or another psychiatric disorder, or with vulnerability towards psychiatric disorders. Patients suffering from atypical CBS should be closely followed psychiatrically and neurologically. Patients suffering from the typical CBS should also benefit from a psychiatric follow-up, due to their multiple psychiatric vulnerability factors and their possible management with psychotropic drugs.
