This study is a quasi-experimental between-group design. Using a prospective two-arm controlled exploratory study, data will be collected on an initial assessment of the effects of a specific neurological sample after thrombotic infarction (PCA infarction) who lost the ability to dream due to the infarction (experimental group) compared to a specific neurological sample after thrombotic infarction (PCA infarction) without loss of the ability to dream (comparison group) in terms of subjective and objective sleep quality and memory consolidation. Besides the importance to further elucidate the role of dreaming for sleep architecture and memory consolidation, the results of the evaluation are of great clinical relevance in a further scientific investigation regarding the treatment of a specifically neurological sample with acute thrombotic infarction.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Other | Mannheim Dream Questionnaire (MADRE) | Acquisition of various aspects of dream experience (a.o. Dream recall frequency; Nightmare frequency; Frequency of telling dreams). The questionnaire contains 21 questions, the patient ticks the appropriate numbers on frequency scales or Likert scales (0 to 4). The frequency scales are used as single items. | Baseline before sleep in sleep laboratory | |
Other | Pittsburg Sleep Quality Index (PSQI) | The Pittsburgh Sleep Quality Index (PSQI) is a self-rated questionnaire which assesses sleep quality and disturbances over a 1-month time interval. Nineteen individual items generate seven "component" scores: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. The sum of scores for these seven components yields one global score. A global PSQI score greater than 5 yielded a diagnostic sensitivity of 89.6% and specificity of 86.5% (kappa = 0.75, p less than 0.001) in distinguishing good and poor sleepers. | Baseline before sleep in sleep laboratory | |
Primary | Change from pre- to post-sleep performance in memory of International Affective Picture System (IAPS) | Emotional memory: number of affective pictures administered pre sleep and remembered post sleep | pre-post sleep after a minimum of 8 hours sleep in sleep laboratory | |
Primary | Change from pre- to post-sleep performance in Finger-Tapping-Task (FTT) | motor sequence learning task for memory consolidation of non-declarative memory; number of correct sequences per 30s is assessed pre and post sleep | pre-post sleep after a minimum of 8 hours sleep in sleep laboratory | |
Primary | Polysomnography (PSG) | Sleep Quality measurement: Total sleep time (TST); Duration of sleep stages - S1t, S2t, S3t, Rapid Eye Movement - REMt; sleep onset latency - SL; wake after sleep onset - WASO; sleep efficiency - SE. | 8 hours | |
Secondary | Change in Wechsler Memory Scale (WMS-IV) | Wechsler Memory scales (declarative memory); test battery for adults; Raw values are converted to scale value points using an age-related conversion (SVP 1-19; mean 10; standard deviation 3). The value points of the scale-related subtests form scale sums, which in turn are converted into indices (40-160, mean 100; standard deviation 15). | pre-post sleep after a minimum of 8 hours sleep in sleep laboratory | |
Secondary | Change in Wechsler Adult Intelligence Scale (WAIS-IV) | Individual test procedure for assessing the cognitive abilities (Working- and short-term-memory) of adolescents and adults aged 16;0 to 89;11 years. An overall IQ is calculated using the value point sums of the 10 subtests and serves as the basis for interpreting the individual subtests. As a measure of change subtest scores are compared pre-post sleep | pre-post sleep after a minimum of 8 hours sleep in sleep laboratory | |
Secondary | Change in California Verbal Learning Test (CVLT) | Test-battery to assess declarative memory performance. Both free recall and recognition of two word lists across immediate trials and short- and long-delayed trials are measured. Subject is asked to reproduce as many words as possible from List A immediately after each presentation. List A is composed of 16 words that can be assigned to four semantic categories. A second list B, also with 16 words, is presented once to investigate interference effects. Immediately after the free recall of list B, the short-term free recall and the short-term recall with mention of the semantic headwords of list A as an aid take place. In the subsequent interval of 20 minutes, non-verbal test procedures are performed. This is followed by long-term free recall (Delayed Free Recall II), long-term recall with naming of semantic headwords, and Yes/No Recognition. Scores are compared pre-post sleep. | pre-post sleep after a minimum of 8 hours sleep in sleep laboratory |
