[Impairment of attention and executive functions in patients with paranoid schizophrenia].

To study changes in attention and executive functions during psychopharmacotherapy in patients with paranoid schizophrenia, we have examined 120 patients with a first episode of paranoid schizophrenia treated with typical and atypical neuroleptics. Clinical and statistical analyses have revealed the heterogeneity within treatment groups that allowed to define two subgroups. These subgroups were characterized by a differed disease course (favorable or poor type).
