NARSAD Distinguished Investigator Grantees Robin M. Murray, M.D., D.Sc. and Philip McGuire, M.D., Ph.D., both professors at King's College Institute of Psychiatry in London, are among the authors who led a new study that may help explain why approximately one-third of patients with schizophrenia do not respond to traditional antipsychotic medication. The study was published in the November issue of the American Journal of Psychiatry.

“Despite considerable scientific and therapeutic progress over the last 50 years, we still do not know why some patients with schizophrenia respond to treatment whilst others do not. Treatment resistance in such a disabling condition is one of the greatest clinical and therapeutic challenges to psychiatry, significantly affecting patients, their families and society in general,” the authors wrote.

Through the use of positron emission tomography (PET) imaging, the researchers found that treatment-resistant patients had normal levels of dopamine synthesis capacity when compared to patients who responded well to antipsychotic medications. Since most antipsychotic medications work by blocking dopamine, they believe that their finding could explain the different responses to medications.

The authors wrote further: “Our findings suggest that there may be a different molecular mechanism leading to schizophrenia in patients who do not respond to antipsychotic medication. Identifying the precise molecular pathway particularly in these patients is of utmost importance and will help inform the development of much-needed novel treatments."

my son jeff 44yrs has been on med's since age 22 with schizophrenia will their be improve as he ages?

This may sound far out there, but I wonder if the pineal gland and/or the pituatary gland have some connection with schizophrenia. Whenever I read about metaphysical info on mental illness, there's a common denominator that always points to two glands: the pituary gland and the pineal gland. Far fetched? Who knows, but why not leave no stone unturned?

the Brain and Behaviour Institute is needed by persons who can and should be empowered with more information and education
regardind heir mental problems and heredity history. Please do
more education for consumers. Thank you!
