REVIEW
Dong Woo Kang, Chang Uk Lee, Hyun Kook Lim
Sleep disturbances such as insomnia, hypersomnia, and circadian rhythm disturbance are common in normal elderly and Alzheimer's disease (AD) patients. To date, special attention has been paid to sleep disturbance in the clinical course of AD insofar as the interaction of sleep disturbance with the pathogenesis of AD may impact the clinical course and cognitive function of AD patients. This review covers the bidirectional relationship between sleep disturbance and AD pathogenesis; the associations between sleep disturbance and AD-specific neurotransmitters, brain structure, and aspects of sleep disturbance in each phase of AD; and the effects of sleep disturbance on the cognitive functions of patients in each phase of AD...

BACKGROUND: Durations of nocturnal sleep and daytime nap influence the well-being of older adults. It is thus essential to understand their determinants. However, much previous research did not assess sleep duration and nap duration individually, and longitudinal data is lacking. This study aimed at examining the impact of demographic, psychosocial, and health factors, including ethnicity, social networks outside the household, smoking and physical exercise on sleep duration and nap duration among community-dwelling elderly...

OBJECTIVE: Suvorexant is an orexin receptor antagonist approved for treating insomnia at doses of 10-20 mg. Previously reported phase III results showed that suvorexant was effective and well-tolerated in a combined-age population (elderly and nonelderly adults). The present analysis evaluated the clinical profile of suvorexant specifically in the elderly. METHODS: Prespecified subgroup analyses of pooled 3-month data from two (efficacy) and three (safety) randomized, double-blind, placebo-controlled, parallel-group trials...

Acute symptomatic seizures and epileptic disorders are frequent health problems of elderly patients. An early and reliable distinction of the seizure etiology is important to ensure adequate treatment, and to prevent unwarranted diagnostic and therapeutic procedures. The most common causes of acute symptomatic seizures - acute cerebrovascular disorders, metabolic disorders, traumatic brain injury, meningo-encephalitis, cerebral tumors, and withdrawal of alcohol and other central agents - are well-defined and seem to permit straightforward diagnostic and therapeutic strategies...

Douglas Galasko
Dementia syndromes associated with Lewy bodies are subdivided into dementia with Lewy bodies (DLB), an underdiagnosed cause of dementia in the elderly, and Parkinson disease with dementia (PDD), cognitive impairment appearing in people diagnosed with Parkinson disease. Their neuropathologic substrates are the widespread distribution of aggregates of the protein α-synuclein in neurons in cortical brain regions, accompanied by variable Alzheimer pathology. Clinical features of DLB and PDD include distinctive changes in cognition, behavior, movement, sleep, and autonomic function...

BACKGROUND: Gastrointestinal symptoms are a well-recognized and common premotor feature of Parkinson's disease (PD). Moreover, multiple studies have assessed the value of colonic α-synuclein as a potential marker of prodromal PD. Recently, the International Parkinson and Movement Disorders Society (MDS) defined research criteria for prodromal PD. OBJECTIVE: The aim of our study was to test the MDS research criteria in patients undergoing diagnostic colonoscopies as potential candidates for inclusion in prospective trials evaluating colonic biopsies as a potential biomarker of prodromal PD...

Aging is associated with increases in hypothalamic-pituitary-adrenal (HPA) axis activity that can predispose to metabolic and cognitive impairments. We investigated in elderly and young subjects whether intranasal insulin administration to the human brain reduces early-sleep nadir concentrations of adrenocorticotropin and cortisol, that is, indicators of baseline HPA axis activity. In within-subject comparisons, intranasal insulin (160 IU) or placebo was administered to 14 elderly (mean age 70.0 years) and 30 young (23...

BACKGROUND: Sleep complaints are prevalent in older patients. Sleepiness, short or long sleep duration and obstructive sleep apnea (OSA) are associated with insulin resistance (IR). These parameters have not yet been considered together in the same study exploring the possible association between IR and sleep in older patients. IR is involved in cardiovascular and metabolic diseases, pathologies which are highly prevalent in older patients. Here we assess, in older non-diabetic patients with sleep complaints, the associations between IR and sleep parameters objectively recorded by polysomnography (PSG) rather than self-report...

BACKGROUND: Health literacy is a critically important skill that helps people become active participants in their health care. Multiple studies in the United States and across the world have documented the association of health literacy with multiple health outcomes. In particular, the elderly and many members of minority groups have been shown to have low levels of health literacy; the same groups are disproportionately affected by chronic illnesses. These twin burdens affect the people most in need of the skills and knowledge required for coping with chronic illnesses...

BACKGROUND: Mild parkinsonian signs (MPS) are frequent in the elderly population and associated with the presence of risk markers for Parkinson's disease (PD). Both MPS and non-motor signs may be present in prodromal PD and may significantly impair quality of life (QoL). OBJECTIVE: To disentangle the contribution of motor impairment and extra-motor manifestations to QoL in subjects with MPS (n=63), manifest PD (n=69), disorders with motor symptoms due to non-neurodegenerative diseases (n=213) and healthy controls (n=258)...

Age is one of the main risk factor for the presence of obstructive sleep apnea (OSA). This syndrome is associated with hypertension, cardiovascular disease, cognitive impairment and metabolic abnormalities, such as type 2 diabetes. Continuous positive airway pressure (CPAP) represents the gold standard therapy, but its benefit is still to be determined in very elderly. We report the blood pressure and metabolic changes in a very elderly obese with severe OSA after 3-month CPAP therapy. We have evaluated a very elderly obese male affected by severe symptomatic OSA, poor controlled nocturnal hypertension and insulin resistance...
