Background: Telemedicine is one of the most modern and fastest-growing branches of medicine. The most common form is video consultation. We distinguish between synchronous and asynchronous telepsychiatry. This study aims to show the benefits of using telepsychiatry services, the challenges it poses to users, and to evaluate its use against traditional therapy. Materials and methods: A review of literature from 1956-2023 in EMBASE, OpenKnowledge and PubMed databases was conducted. Keywords used were: telepsychiatry, teletherapy, and digital psychiatry. Ninety-eight articles were included. Discussion: Telepsychiatry is an opportunity for regions affected by medical staff shortages. It bypasses cultural barriers, the problem of traveling and reduces the cost of medical point-of-service. Telepsychiatry is an opportunity for patients who do not use psychiatrists due to discrimination in a conservative society. Groups that may find it challenging include the elderly, the blind, and the deaf. Creating a healthy therapeutic alliance through a screen can be impossible, making it difficult to achieve successful therapy. A barrier to developing telepsychiatry is the need for more guidelines for dealing with medical errors. Conclusions: Telemedicine can help in accessing specialized care regardless of location. Telepsychiatry provides a safe and anonymous environment for patients reluctant to receive inpatient therapy. The effectiveness of online therapy is primarily debated. Telepsychiatry should be limited to follow-up consultations and well-known patients - it is a form of complementing the diagnosis and treatment process. The authors point to the need for developing specific guidelines for conducting teletherapy with particular attention to the problem of suicide. Keywords: telepsychiatry, teletherapy, digital psychiatry.

Introduction: Artificial intelligence research is increasing its application in mental health services. Machine learning, deep learning, semantic analysis in the form of transcriptions of patients' statements enable early diagnosis of psychotic disorders, ADHD, anorexia nervosa. Of great importance are the so-called digital therapists. This paper aims to show the use of AI tools in diagnosing, treating, the benefits and limitations associated with mental disorders. Material and methodS: This literature review was conducted by searching scientific articles from 2015 to 2022. The basis were PubMED, OpenKnowledge, Web of Science, using the following keywords: artificial intelligence, digital therapy, psychiatry, machine learning. Results: A review indicates the widespread use of AI tools in screening for mental disorders. These tools advance the clinical diagnosis medical specialists make up for several years. They impact solving medical staff shortages, lack of access to medical facilities and leveling patient resistance to treatment. The benefits are ultra-fast analysis of large sets of information, effective screening of people in need of specialized psychiatric care, reduction of doctors' duties and maximization of their work efficiency. During the current COVID 19 pandemic, robots in the form of digital psychotherapists are playing a special role. Conclusions: The need for further research, testing and clarification of regulations related to the use of AI tools is indicated. Ethical and social problems need to be resolved. The tools should not form the basis of autonomous therapy without the supervision of highly trained professionals. Human beings should be at the center of analysis just as their health and well-being. Keywords: artificial intelligence, digital therapy, psychiatry, machine learning
