Tardive dyskinesia is a disease that involves repetitive involuntary muscular movements. The degree can vary from mild to severe. Unfortunately there is no good treatment. Most would say at present there is no cure.It most common cause is as a side effect from neuroleptic antipsychotic medication. Studies have shown that there has been some minimal help from antiparkinson drugs as well as bezodiazipines. This however is contested and any benefits appear to be minimal with significant danger of side effects.
Unsubstantiated natural remedies are Alpha-Tocopherol, or rhodiola, omega 3 fatty acids or melatonin.although they have no proven efficacy in controlled studies.
