Patients with schizophrenia could soon be prescribed tailored drugs for their biology, as a new project gets underway in the Centre for Brain Research. Funding from the Auckland Medical Research Foundation has enabled promising Research Fellow Dr Valerie Anderson to undertake the research.
Standard medications are not affective in approximately a third of people with schizophrenia, and these patients are considered ‘treatment-resistant’. Alternative medication and combinations of antipsychotics must be used, but these medications have a greater risk of inducing serious side effects and therefore are avoided where possible. Consequently, people with treatment-resistant schizophrenia often experience many years of unsuccessful therapy with standard medications before alternatives are prescribed, during which time their symptoms severely affect daily living and have a significant impact on long-term outcomes.
The Psychopharmacology team will now investigate whether they can identify measurable biological characteristics (biomarkers) that could be used to predict whether people with schizophrenia will be treatment-resistant. Brain magnetic resonance imaging, electroencephalography, and neuropsychological data will be collected and analysed to investigate the structure and function of the brain in people with schizophrenia who are treatment-resistant, and the findings compared to people with schizophrenia who respond well to standard medications and normal subjects.
Identification of reliable biomarkers to predict treatment-resistant schizophrenia would enable alternative medications to be prescribed earlier in the disease course. This will ultimately minimise the time that these patients experience debilitating symptoms, leading to improved outcomes for them, and reducing the burden on their families and health care providers.
The Auckland Medical Research Foundation has also funded two new PhD scholarships at the Centre for Brain Research. Foundation Executive Director Kim McWilliams says: “Many of these researchers already have and will go on to become leaders and internationally recognised in their particular discipline or field of medicine.”
