I have noticed recently that the attributions of diseases and disorders for many famous people are shifting. Vincent Van Gogh, for example, has long been considered epileptic, but recently, has been decreed bi-polar instead. The symptoms are the same, but the designation has been changed.
But, then there is a bigoted strain of reluctance still present among many writers who simply refuse to name E. even in the face of medical history. Lewis Carroll, Napoleon Bonaparte are two examples. Though the diaries of both men write that they have E., many historians simply leave out or work diligently to reappraise their symptoms so that they can rediagnose them as suffering some other condition than epilepsy.
