Early interventions for first onset of symptoms of mental health conditions: an umbrella review of systematic reviews

Despite its great importance in reducing the global burden of mental ill-health, review evidence on early intervention following symptom onset remains limited, especially for conditions other than psychosis.

Innovative approaches for eating disorders have emerged, but treatments supported by substantial and robust trials are urgently needed. Further evidence is also required for conditions including depression, anxiety, bipolar disorder, and 'personality disorder'.
