The following information, found on PubMed, comes from a single center experience in Tel-Aviv Israel. Patients who suffer from Gilles de la Tourette syndrome experience reduced function and impaired quality of life. The current medical treatments for this can cause significant side effects and only partial symptomatic relief.
A few medical studies have suggested that medical cannabis can provide symptomatic relief with relatively benign side effects. This real life analysis questioned 42 Tourette’s patients who had been treated with medical cannabis. 38 reported a reduction in tic severity, better sleep and improved mood as positive effects.
After one year of therapy 10 of them elected to cease medical cannabis usage for various reasons, including psychosis in one patient. Medical marijuana holds promise and demonstrated high subjective patient satisfaction, but warrants further side effect investigation.
