Intervention in at-risk states for developing psychosis
Indicated prevention is currently one of the most promising approaches to fight the individual and societal burden associated
with psychosis and particularly schizophrenia. The number of studies is still limited, yet encouraging results have been reported
from pharmacological and psychotherapeutic trials. Furthermore, it has become clear that persons characterized by the at-risk
criteria are already ill and do not only need preventive intervention but also treatment. As is indicated by a recent study
successfully using omega-3 fatty acids for both purposes, it may be promising to develop and investigate interventions especially
for the at-risk state, independent of their effectiveness in manifest disease states. An overview on the current findings
and ongoing research in this area is provided.
