This article compares the efficacy of olanzapine and risperidone for positive and negative symptoms using an 18-week, randomized, double-blind, crossover design. The hypotheses were that olanzapine would be more efficacious for treating negative symptoms, and that risperidone would be superior in treating positive symptoms. Positive and negative symptoms scores improved throughout treatment, regardless of medication type.

The schizophrenia subjects underwent a second MEG recording after 8 weeks of open-label treatment with aripiprazole.

Family psychoeducational support groups in Spain: parents' distress and burden at none-month follow-up.

Forty-one mothers and twenty-seven fathers agreed to participate in a 6-week, low-cost, multiple-family psychoeducational intervention in Spain.
