Traditional Classification Combing early studies, the traditional symptoms of CWS centered on visual irreminiscence, prosopagnosia, and topographic agnosia. However, due to significant differences in the observations of<unk>  and<unk> 's case work, this syndrome bridged the entire loss of dreaming, whether it be due to the isolated inability of the brain to produce images while asleep as<unk>  had dictated, or the complete loss of dreaming all together as with<unk> . This has led to the terming of<unk>  and<unk>  variants, which corresponded to either the loss of dream imagery and visual irreminisence or the complete ceasing of dream experience often coupled with agnosia. Modern Classification There is new focus on the type of injury and analysis of REM sleep pertaining to CWS. A more current medical definition lists CWS as “the association of loss of the ability to conjure up visual images or memories and the loss of dreaming”. A 2004 case-evaluation of a 74-year-old woman who had experienced an acute, bilateral occipital artery infarction which rendered her dreamless for a 3-month period was to perform polysomnography testing in combination with patient dream reporting to determine both her sleep architecture or pattern of sleep stages, and subsequent dream recollection. Such techniques allow for associations between the physiological timetable of dreaming during REM sleep and the patient's ability to recall dreams to be compared closely.
