Answer

Answer

TD occurs in all ages. Connor et al found that 5.9% of 95 young people aged 7-21 years who received dopamine antagonist treatment for 3 months had TD. [29] Advanced age is a major risk factor for TD. [30] The prevalence of TD is 29% in elderly patients receiving dopamine antagonist treatment for 3 months and 26-67% in patients undergoing long-term treatment.
