Telepsychiatry is shifting the focus of psychiatry and psychotherapy from personal interaction and relationship building to communication with technological mediators in the form of telecommunication, virtual reality (VR), social robots or artificial intelligence (AI). This article discusses the opportunities and risks of new technologies in psychiatric treatment, taking into account the principles of medical ethics. Telepsychiatric treatments can promote self-determination in the home environment as opposed to institutionalisation but carry the risk of uncontrolled data sharing. They harbour risks of potential harm such as social isolation, negative effects on the doctor-patient relationship and long-term changes in patient behaviour through, for example, VR. In terms of justice, demographic and psychopathological factors could result in unequal access to telepsychiatry, with questionable sustainability effects. The anonymity of telepsychiatry threatens alienation, while moral considerations cannot be replaced by AI for the time being. It is obligatory to carefully weigh up the benefits and risks of telepsychiatry, but especially in rural areas they could optimise care.Precisely because of ethical concerns, further intensive research is necessary to weigh up the risks and benefits. The development of telepsychiatric systems requires transdisciplinary co-operation. At a societal level, the significance of technologies as a supplement or replacement for the doctor-patient relationship needs to be discussed.
