Coprolalia in aphasic patients with stroke: a longitudinal observation from the BLAS2T database.

The BLAS2T (bilingual aphasia in stroke-study team) initiative has been a multi-center attempt to investigate longitudinal changes in language function in a cohort of stroke subjects. This report discusses linguistic performance in four cases from the BLAS2T database who demonstrated coprolalia as an irresistible urge to say obscene words.  Coprolalia was found to partly resolve in a 30-day follow-up in three cases. Recognition of coprolalia and language recovery patterns in bilingual aphasic patients with stroke would potentially lead to their even better individualized care and neurolinguistic/cognitive rehabilitation.
