title: Synaptic plasticity and mood disorders.
abstract: Recent studies demonstrate that the molecular elements known to regulate neuronal plasticity in models of learning and memory are also involved in the actions of drugs used for the treatment of depression and bipolar disorder. This includes up-regulation of transcription factors, such as the cAMP response element binding protein and neurotrophic factors, such as brain derived neurotrophic factor. These findings raise the possibility that regulation of neural plasticity in specific neuronal circuits is integrally involved in the therapeutic intervention of mood disorders. Atypical antipsychotic drugs, including clozapine and olanzapine, are also effective for the treatment of bipolar disorder, and are used as add-on medication for unipolar depression. The possibility that these atypical antipsychotic drugs also influence the molecular determinants of synaptic plasticity that are involved in the response to drugs used for the treatment of mood disorders, is discussed.
