Tourette syndrome treatment

[edit]

Citation needed for biperiden's usage in treating Tourette syndrome.

All I could find was a case report of treating extrapyramidal symptoms caused by dopamine antagonists in a Tourette syndrome patient.

This one showed resolution of symptoms:

https://doi.org/10.1345/aph.1g331

I also found a case study of biperiden in a patient with schizophrenia and Tardive Tourette-like syndrome induced by antipsychotics, in which it appeared ineffective.

I could not find any source regarding the treatment of TS-proper with biperiden. Sappygang (talk) 12:33, 5 April 2024 (UTC)[reply]
