[Benefits and challenges of eHealth in depression]

Depression is a common and debilitating pathology with a significant socioeconomic impact. Early and optimal treatment can help to reduce its progression towards chronicity and long-term cognitive disorders. In the context of falling numbers of medical professionals and the poor provision of validated tools, such as cognitive behavioural therapy, the use of eHealth in depression presents a clear benefit in terms of diagnostic efficacy, patient autonomy, prevention of relapse and health care costs. Innovation must however be associated with ethical deliberation, which respects the patients and their needs.
