Arms Assigned Interventions
Active Comparator: 1
further maintenance antipsychotic treatment and prodrome-based early intervention
Other: maintained antipsychotic treatment vs. stepwise drug discontinuation
maintained antipsychotic treatment (in low dose) vs. stepwise drug discontinuation; both supplemented by prodrome-based early intervention; 1 year
Experimental: 2
stepwise drug discontinuation (after 1 year maintenance antipsychotic treatment) and prodrome-based early intervention
Other: maintained antipsychotic treatment vs. stepwise drug discontinuation
maintained antipsychotic treatment (in low dose) vs. stepwise drug discontinuation; both supplemented by prodrome-based early intervention; 1 year

Detailed Description:
After one year neuroleptic maintenance treatment in patients with first episode schizophrenia, neuroleptic treatment will be continued vs. stepwise discontinued (randomized design) over a period of 1 year. Under both conditions pharmacologic early intervention strategies in case of early sign of relapse will be applied.
