This volume offers a detailed and up-to-date analysis of the unmet needs of patients with psychoses and personality disorders. These include the needs associated with early detection of ultra-high-risk populations and first-episode psychosis; recognition of the trajectories of bipolar disorder and schizophrenia, recovery, early intervention, such as the use of LAIs, the conundrum of differential diagnosis in various personality disorders, and unsatisfactory quality of life, even in the presence of symptom control. Intended for clinical psychiatrists and other practitioners interested in mental health, this book helps them to manage the challenges of the diagnostic uncertainty in first-episode psychosis and timely interventions, since the earlier diagnosis is confirmed, the sooner multidisciplinary treatment can be implemented and plans for psychoeducation, and relapse prevention drawn up.
