Cluster arousal analysis in chronic pain-disturbed sleep.

A new cluster arousal analysis system was developed to quantify microdisturbances in the sleep architecture. The system was evaluated in 10 healthy volunteers and the sleep of 23 outpatients with chronic low back pain was investigated before and after a special rehabilitative training. The comparison of sleep parameters before and after the treatment showed a significant reduction of the cluster disturbed sleep (CDS), whereas sleep efficiency and the number of stage shifts remained unchanged. The reduction of the CDS correlated with a reduction of depression scale. This cluster arousal analysis appears to be a sensitive tool for evaluating alterations in the sleep microstructure.

[Somnambulism and pavor nocturnus--review and case report].

A case of night terror with sleepwalking in an adult patient is described. Sleep polygraphic data are presented. The literature related to sleepwalking, night terror and its treatment is reviewed. The psychopathologic patterns of sleepwalking and night terror are illustrated and the differentiations of parasomnias and epileptic seizures discussed. The clinical applications of these findings are described and practical recommendations made for the management of NON-REM parasomnia.

Cerebrovascular reactivity to acetazolamide in (senile) dementia of Alzheimer's type: relationship to disease severity.

Neuropathological reports about denervation and amyloid angiopathy in dementia of Alzheimer's type (DAT) as well as signs of selective incomplete white matter infarctions point to a vascular involvement within the degenerative process. In order to investigate potential alterations of cerebrovascular function we performed cerebral blood flow measurements before and after intravenous injection of 1 g acetazolamide using technetium-99m hexamethylpropyleneamine oxime and single photon emission tomography in 12 patients (6 female, 6 male; mean age 70.8 +/- 9.6 years) with probable (senile) dementia of Alzheimer's type (SDAT) and 9 controls (7 female, 2 male; mean age 71.2 +/- 8.6 years). SDAT patients revealed significantly reduced cerebrovascular reactivity with lower values with increasing cognitive impairment. We discuss possible underlying mechanisms.
