Detailed Description:

In case of early signs of a relapse prodrome based early intervention with an antipsychotic drug (Haloperidol, Risperidone and other) vs. benzodiazepine (Lorazepam) was applied in patients with first episode schizophrenia after one year neuroleptic maintenance treatment. Two groups of patients were followed over a period of 1 year: one further on under maintenance neuroleptic treatment (Haloperidol, Risperidone and other) , the other one after stepwise drug discontinuation.
