Differences in neuropsychological correlates between normals and those experiencing "Old Hag Attacks".

Kettlewell N, Lipscomb S, Evans E.

University of Montana, Missoula.

240 university students were given The Cognitive Laterality Battery as well as a questionnaire, the answers to which were used to identify those who had experienced an "Old Hag Attack." This refers to a hypnagogic sleep disorder in which there is paralysis and, quite often, terrifying hallucinations. Those suffering from this disorder showed a statistically significantly different profile of scores from normal subjects on The Cognitive Laterality Battery. The implications of this finding for existing theories concerning "Old Hag Attacks" are discussed.
