In the epicrises of young patients in psychiatric hospitals we often find a history of abnormal silence or withdrawal, and it is supposed that this may be an early sign of a mental disease under development. Until now nobody have dared to suggest that the causality maybe can be reversed - that vocal silence may be the reason for,- or at least the initiating factor for the illness. The hypothesis is this : A certain amount of vibrations from vocalisation (and/or Vibroacoustic stimulation) is necessary in order to keep the brain functioning normally.
