BID DACH Forum

Speculating about the causes of BIID is likely just as difficult as trying to explain the connection between a genetically determined absence of a leg and the sensation of that leg when urinating. (See the example that Prof. P. Brugger has mentioned several times in his articles.)

The apparent link between hearing loss and a simultaneously impaired sense of touch sounds equally puzzling. Genetic researchers in Berlin are investigating this demonstrable phenomenon.
