Program Overview
Schizophrenia and bipolar disorder are severe chronic psychiatric disorders that are associated with significant morbidity and mortality. Schizophrenia has an estimated heritability of 80% (due to interplay between multiple genes and environmental factors). Family studies on patients with bipolar disorder suggest a significant genetic component, but there also appears to be a complex interaction of genetic, neurobiological, and environmental factors. According to recent twin studies, similar genomic regions could play a role in schizophrenia and bipolar disorder.
In recent years, neuropsychiatry has seen an explosion of interest in genetics and brain imaging. Neuroimaging (such as magnetic resonance imaging, functional magnetic resonance imaging, positron emission tomography) has been increasingly utilized to study brain abnormalities associated with schizophrenia and bipolar disorders, which may have neurodevelopmental origins. Advances in neuroimaging may help uncover patterns of abnormal cerebral maturation and thus aid the clinician in early detection of diseases such as schizophrenia and bipolar disorder. Genetic profiles combined with imaging studies have led the way to a greater understanding of the neurobiology of these diseases and identified potential patterns indicative of a shared genetic risk.
Other studies have helped to reinforce psychiatry’s current understanding of receptor pharmacology, so clinicians can better predict efficacy and adverse effects for patients in order to improve adherence and long-term outcomes.
This symposium will review recent genetic and imaging studies and review current atypical antipsychotics used to treat schizophrenia and bipolar disorder. The clinical implications of the differential receptor pharmacology of these agents will also be discussed. Combining information from all of these sources is essential to allow the practicing psychiatrist to improve diagnostic and treatment paradigms for schizophrenia and bipolar disorder.
