I can’t claim a direct connection between Past Lives and foreign accent syndrome, but this article got my attention. From BMJ Journals, Volume 16, Issue 1:
A man in his 50s with metastatic hormone-sensitive prostate cancer, receiving androgen deprivation therapy and abiraterone acetate/prednisone, presented with an uncontrollable ‘Irish brogue’ accent despite no Irish background, consistent with foreign accent syndrome (FAS). He had no neurological examination abnormalities, psychiatric history or MRI of the brain abnormalities at symptom onset.
This may be more of a human brain anomaly as the man is reported to have friends in the UK, but I always have to consider the emergence of an Adjacent/Past Life personality when I hear these reports. Food for thought…
