Mental Health




Among the poorest of the poor population are people with psychological illnesses. If minor problems are often supported with local resources (relatives, healers, religious bodies, etc.), serious problems do not find a solution and the sick are often victims of abuse and mistreatment. In addition, problems such as psychosis and schizophrenia usually affect adolescents or young adults, who are thus seriously invalidated for their entire lives and are a burden to the community.




Antenna Technologies is partner of a study evaluating a verbal tool to improve the management and prognosis of patients with psychotic disorders.

This tool is lightweight and portable as it is based on the power of words. About a set of specific, cross-cultural use, developed from the observation of hundreds of patients, about which control can be taught to local officials. This tool was developed by a group of psychiatrists, psychologists, psychiatric nurses and improved based on feedback from patients and clinical studies conducted with a hundred of them.

The « Crisis Dialogue » is derived from recent acquisitions including neurosciences and their applications in clinical psychiatry. This new approach is used to help support people with serious mental problems, in a respectful manner. It is part of an overall support to the health system, in that it is also used to help patients and their relatives to care without stigmatizing the disease, access to medication, etc.

The overall objective is a quick exit from the psychotic crisis, reduced relapses and improved patient autonomy in daily life.

One of the advantages of the proposed method is being used with limited resources in all socio-economic contexts. A pilot study was conducted in Switzerland (Geneva and Yverdon) to provide an estimate of the effects of the new method. The results were encouraging and seem to bring a reduction of trauma to the onset of psychosis and an accelerated return to normal life. Patients receiving Dialogue crisis evolve very positively during the 10 days following admission. Since 2011, the “Crisis Dialogue” tool has been used in Palau (Asia-Pacific) and the methodology has been translated into Arabic for further dissemination.
