London - A Scottish woman went to bed with a headache and woke up speaking with a South African accent, a British doctor said yesterday. The unidentified woman, in her 50s, had a completely different voice with an intonation more familiar in Capetown than in Edinburgh. Doctors say she had a minor stroke and is now suffering from Foreign Accent Syndrome, a rare condition in which patients acquire a completely different accent after suffering a stroke. Only 12 previous cases have been reported.
