Dr Conolly Norman reviewed the issue of beri-beri in asylums in 1899. He pointed out that following the outbreak in the Richmond Asylum, others had occurred in Suffolk, England, Alabama and Arkansas in the USA, and at St. Gemmes-sur-Loire in France. Norman remained puzzled as to the possible causes: sometimes there seemed to be an association with nutrition but he thought that the Richmond diet was quite as good as in other asylums.
He wondered about a ‘miasmatic poison’ especially in conditions where the ground was damp and marshy, and subject to frequent excavation as was common with asylums. (He is probably thinking here of the frequent building works, probably on top of human waste and, indeed, buried corpses.)
He decided that ‘infective peripheral neuritis’ would be an appropriate term, and that at least asylum doctors needed to be aware of the problem even if the cause and treatment were unknown.
