Filter by:Tardive dyskinesia (TD) is a well-known complication of antipsychotic drug therapy in individuals treated for mental disorders such as schizophrenia. It typically consists of purposeless, involuntary movements involving the mouth area or the trunk and limb muscles, occurring within months or years of drug use. The annual incidence of TD in the population treated with antipsychotic drugs is between 1-5%, but the risk is 5-fold greater in older individuals. Once triggered, TD is often irreversible and untreatable. Its cause is unknown, but an imbalance between chaotic mechanisms triggered by the drugs and natural protective factors fighting against these may provide an explanation. One way to activate this protective response is to supplement the diet with high doses of essential fatty acids of the omega-3 class, which constitute a critical component of nerve cell membranes. Using this strategy, one research team showed a 50% reduction in the severity of TD-like movements in mice treated with docosahexaenoic acid (DHA). We hypothesize that DHA supplements can do the same in patients living with schizophrenia displaying TD movements. Forty (40) subjects between 30-75 years of age will be recruited. The participants will be randomized and equally distributed in two groups to take either DHA capsules (3 grams a day) or matching placebo for 12 weeks, after providing informed consent, and TD will be measured with a magnetic tracker system and clinical scales. The finding of a beneficial effect with DHA against TD would improve the quality of life for thousands of patients under long-term antipsychotic drug treatment.
