Reason why some people get nervous tics Tardive dyskinesia is a motor disorder characterized by uncontrolled facial movements. Such as repeated tongue movements, sucking movements, and involuntary grimacing. And almost all cases of tardive dyskinesia are provoked by taking neuroleptics — these drugs block dopamine receptors. When they are taken long-term, new hypersensitive receptors rise from the postsynaptic membrane (which receives dopamine) to "replace" the blocked ones. As a result, previously rejected dopamine binds to them and leads to excessive signal transduction⚡️ This affects the motor areas of the brain and provokes those very nervous tics. Our NFT channel
