nocturnal delirium

Definitions

A state of agitation or confusion, especially in elderly patients suffering from Alzheimer's disease or other forms of dementia, which begins daily at nightfall and which is alleviated by daylight.

Examples

“Nocturnal delirium of the senile patient is primarily due to the fact that the severe retention defect, and more particularly the greatly accelerated secondary elaboration (Cameron, 1940) found in senile patients, does not permit⟳ of the preservation of the spatial image after darkness has interfered with direct⟳ visualization.”

“The nocturnal deliria were piled together with the daytime intoxications and obsessions in order⟳ to build⟳ a particularly adaptable dream⟳ machine, which still awaits a visit⟳ from social psychoanalysis in order⟳ to penetrate a bit more lucidly into the ancien régime's intricate labryinth of dreams.”

“Preliminary observations by means of motor activity recordings made it possible to classify demented patients with delirium into different groups according to their motor activity, e.g. nocturnal delirium type⟳, wandering type⟳, hypoboulic type⟳, and lying-down type⟳ (Honma et a., 1998).”
