Molecular genetics of schizophrenia: a critical review.

We present an overview of current progress and future directions in the molecular genetics of schizophrenia. We review linkage studies, involving the genome-wide scan of chromosomes with closely spaced polymorphic markers, and association studies of candidate genes, identified on the basis of receptors, neurotransmitters and response to certain drugs. The limitations of the research methodology involved in analyzing such a complex disorder are discussed, as are methods to strengthen this methodology with newer statistical and technological advances to give results that are replicable, statistically significant and applicable to a wider population.

Neuroleptic malignant syndrome in an adolescent receiving olanzapine-lithium combination therapy.

A 16-year-old boy developed fever, generalized rigidity, leukocytosis, and increased serum transaminase and creatine kinase levels while receiving treatment with olanzapine and lithium. When both drugs were discontinued, his fever and rigidity subsided and biochemical irregularities spontaneously returned to normal, without any complications. Classic neuroleptic malignant syndrome (NMS) was diagnosed.
