The Shervert H. Frazier Research Institute at McLean Hospital supports a multidisciplinary team of basic and clinical scientists devoted to understanding the causes and developing new treatments for major psychiatric disorders, especially mood, psychotic and anxiety disorders. Techniques and discoveries arise from clinical, laboratory and brain imaging components.

Clinical Trials

An overview of our Clinical Trials effort is presented in Table I. Trials of kappa modulators are moving from the laboratory to the clinical arena for the first time. Ongoing or follow-up trials of promising early studies include the pursuit of low field magnetic stimulation (LFMS, which originally came from observations in our Brain Imaging Center), the combination of omega-3 fatty acids and cytidine (which may have synergistic effects on mood as suggested in our preclinical studies) and taurine (which showed success in early clinical trials). We are beginning several pilot studies that could represent significant new directions for therapeutics, including the treatment of bipolar disorder with mitochondrial supplements and bipolar depression with SAMe. We have initiated studies to evaluate whether rtfMRI neurofeedback can be used in the treatment of mood and anxiety disroders.

Mania Acute Changes Scale (MACS)

In the past, rating scales for mania have been designed to assess symptoms over many hours or days. Clinical researchers supported by the Frazier Institute are interested in looking at more rapid changes in manic symptoms. To do this, they have developed a novel rating scale called the Mania Acute Rating Scale, or the MACS for short. The MACS is being used at McLean in clinical trials of new agents for treating mania and bipolar disorder.

Genetics

With the sequencing of the human genome and the increasing power of genetic analysis, the pace of discovery of risk genes for human illness, including psychiatric disorders, has accelerated. We are collaborating with the Broad Institute at MIT and Harvard and its affiliated hospitals to identify genes that determine

At present, over 250 patients are volunteering for these studies yearly.

Preclinical Research

Studies performed in our preclinical component are summarized in Table II. Animal studies at our center on the effects of current antidepressant and antimanic drugs point to an important role for the peptide neurotransmitter dynorphin, acting through kappa receptors, in the determination of mood state and psychosis. Based on this information, we are working to synthesize and test agents that act at kappa receptors to produce mood stabilizing effects. We are developing agents that modulate trace amines, which may help regulate mood and cognition. We have promising leads on new ways to treat bipolar disorder through nerve and glial cell growth in the brain and through replacement of dysfunctional cell elements. We have new evidence on the circuits underlying the stress response which may trigger episodes of PTSD and other psychiatric disorders. We have initiated a new model system using C. elegans to study current drugs and discover new targets for novel treatments of bipolar disorder and schizophrenia.

Brain Imaging

Brain imaging remains an important component of our work. It is focused on techniques and projects directly relevant to treatment development and testing (Table III). The work specifically emphasizes spectroscopic imaging of brain chemistry and functional imaging of brain activity related to psychiatric illness and treatment response. Imaging studies have not only suggested the value of LFMS, but helped suggest the use of uridine derivatives to correct abnormal metabolic findings in bipolar disorder and schizophrenia.
