[Advances in the investigation of schizophrenia]

The recent advances in the investigation of schizophrenia were reviewed. Three major fields are considered relevant: 1. Genetic studies with the remarkable finding of the 6pter-p22 chromosome linkage study, which will lead to better understanding about inheritance of disease in the future; 2. The new x-ray techniques, including our own investigations showing smaller brain size in our patients, and 3. The prominent new antipsychotic drugs, as effective as the older drugs but with fewer side effects.
