“…A recent 24-hour actigraphic study performed in institutionalized dementia patients showed four types of abnormal rhythms: a free-running (phase-delayed) type, an aperiodic type, an ultradian rhythm type with a cycle lasting 3 to 4 hours, and a flattened amplitude type in which patients were largely bedridden. 4 Sundowning defines the tendency of demented people to nocturnal agitation. Sundowning can be a primary factor leading to the decision to institutionalize a patient.…”

Insomnia is the most common sleep complaint. Insomnia is not a disease itself but mostly a clinical sign of an underlying disease. Degenerative and vascular diseases involving the central nervous system (CNS) may impair sleep either as a result of the brain lesion or because of illness-related discomfort (motor immobility, social and familial impairment, depression, drugs). Some neurological conditions characterized by movement disorders that start or persist during sleep hinder sleep onset and/or sleep continuity, causing a poor sleep complaint. CNS lesions and/or dysfunction in three specific neurological conditions (fatal familial insomnia, Morvan's chorea, and delirium tremens) impair the basic mechanisms of sleep generation inducing a syndrome in which the inability to sleep is consistently associated with motor and sympathergic overactivation. Agrypnia excitata is the term that aptly defines this generalized overactivation syndrome.

Higher Frequency and Complexity of Sleep Disturbances in Dementia with Lewy Bodies as Compared to Alzheimer's Disease

Background: Sleep disturbances (SDs) are common in patients with all forms of dementia. However, most studies focus on Alzheimer's disease (AD) and less is known about the prevalence and characteristics of SD in dementia with Lewy bodies (DLB). Objective: The aims of this cross-sectional study were: (1) to examine the frequency of SD in DLB versus AD; (2) to compare patients with and without SD with regard to relevant clinical variables, and (3) to investigate the associations between SD and medication use. Methods: Patients with a first-time diagnosis of probable or possible DLB or AD were selected from the Dementia Study of Western Norway and recruited from clinics for old age psychiatry from 2010 until the end of 2013. Results: In all, 123 (55.7%) subjects with dementia suffered from at least one SD. Insomnia was present in 77 (34.8%), and 34 (20.7%) patients had probable REM-sleep behaviour disorder (RBD). All SDs were also significantly more frequent in patients with DLB than in AD, and DLB patients also more often had several co-occurring SDs. The presence of any SD was associated with more neuropsychiatric symptoms, higher morbidity, more parkinsonian symptoms and excessive daytime sleepiness. Antiparkinsonian medication was used more often in RBD, restless leg syndrome (RLS) and periodic limb movements, and benzodiazepines were also common in RLS. Conclusions: Sleep problems are more common in DLB patients compared to AD, and are associated with more clinical impairment. DLB patients frequently have several sleep problems occurring simultaneously, which suggests a need for screening and accurate assessment of sleep in DLB.

“…Its main weakness is that it underestimates high nocturnal agitation in some cases. These results depend on the system's calibration; thus, activity measured using other systems could differ 5 . The nurses were easily able to integrate this scale in their routine patient assessment.…”

graphy did not identify ischemia or infarction in the myocardial territories supplied by the LAD, but there was a false-positive result for the inferior segment. Differentiation of the LAD proper from a total occlusion with developed collateral circulation is crucial, especially in older individuals with cardiovascular risk factors, to avoid an unnecessary revascularization procedure. Mapping of the perfusion of all myocardial segments supplied by the arteries visualized may be vital to avoid incomplete or unnecessary revascularization procedures.
