Studies in senile nocturnal delirium


  1. 1.

    Senile patients suffering from nocturnal delirium were found to develop this delirium on being placed in a dark room during the day.

  2. 2.

    They were also found to suffer from severe impairment of their capacity to retain what they had registered.

  3. 3.

    It was suggested that their delirium may be based upon an inability to maintain a spatial image without the assistance of a repeated visualization.

  4. 4.

    Thirteen out of 16 of these patients when blindfolded showed a severe distortion of their spatial image within an hour. This supports the above hypothesis.
