Do the newer generation atypical antipsychotics pose a lower risk of TD?
Yes, the newer atypical antipsychotics are much safer than the older generation when it comes to TD. The first year incidence of TD with risperidone, olanzapine, quetiapine, and ziprasidone in young persons about 0.5%, which is ten-fold lower than with haloperidol. Similarly, the incidence of TD with atypical antipsychotics in the first year in geriatric patients is 2.5%, which is also ten-fold lower than with haloperidol. There is also growing evidence that the incidence is even lower in subsequent years of exposure to atypicals. The problem of TD has been significantly reduced with the advent and wide-spread use of atypical antipsychotics. What are the symptoms of TD and is TD reversible? As described above, the main symptoms of TD are continuous and random muscular movements in the tongue, mouth and face, but sometimes the limbs and trunks are affected as well. Rarely, the respiration muscles may be affected resulting in grunts and even breathing difficulties. Sometimes, the legs ca
