AbstractPrevalence studies suggest that Alzheimer’s disease (AD) and dementia with Lewy bodies (DLB) are the most common dementing illnesses in the elderly. The aim of this narrative review was to provide data on sleep-related behaviors in AD and DLB. This paper contains arguments, with a clinical approach, on both circadian rhythm changes and dissociated states of wakefulness and sleep in these two conditions.

Research background and hypothesis. Since 2009 Lithuanian Armed Forces have been formed from soldiers in professional service. Research on military physical fitness in the Lithuanian Armed Forces is scarce. This research aims  at  verifying  the  hypothesis  that  physical  fitness  indices  of  soldiers  in  the  Land  Force  of  the  professional Lithuanian Armed Forces match the established physical fitness normative requirements.Research aim was to study peculiarities of changes in physical fitness results of soldiers of different age groups in the Land Force of the Lithuanian Professional Armed Forces in the period of two years. Research  methods:  literature  review,  physical  fitness  testing,  statistical  analysis  of  physical  fitness  indices. Results in each physical fitness exercise were evaluated in points according to physical fitness normative scales. The sum of points for all exercises was the final physical fitness evaluation result. Research results. In the period of half a year, from spring to autumn and from autumn to spring, physical fitness of soldiers in all age groups changed only slightly (p > 0.05). During the period of one year, from testing in spring till testing in spring of the following year, physical fitness indices improved (p < 0.05). Even 2–4% of soldiers failed physical fitness normative tests. Discussion and conclusions. Physical fitness indices of different exercise for soldiers in the Land Force of the professional Lithuanian Armed Forces were higher than the established minimal normative requirements. The highest physical fitness indices were achieved in the age groups of 18–21, 22–26, 27–31 and 30–36 years, however, the differences between the age groups were insignificant. In perspective, while developing military physical fitness control system, the evaluation of physical fitness should be differentiated according to the normative scale which includes such evaluations as “excellent”, “good”,  “fair”.Keywords: Land Force, physical fitness, testing, physical fitness test, age group, points.

Background. A relationship between attention deficit hyperactivity disorder (ADHD) and obesity has been consistently documented. Obesity and metabolic syndrome have been associated with misalignment between daily activities and circadian rhythm. ADHD patients have a high prevalence of delayed sleep phase syndrome, which is a circadian rhythm disorder. Understanding this relationship is important for the evaluation of obese population at risk. Objective. The aim of this narrative review was to summarize the information updated until 2019 about the role of circadian rhythms in obese ADHD individuals. Method. A search was performed in MEDLINE, EMBASE, and Google Scholar database. The terms ADHD, obesity, circadian rhythm, sleep disorders, adolescent, adult, Adolesc, circadian, attention deficit hyperactivity disorder, and child were combined with logical functions. Results. A total of 132 articles were reviewed. Evidence showed that ADHD subjects have an increased risk to present obesity and circadian rhythms disorders. Some possible pathways for this relationship have been hypothesized including obesity as a risk factor, an underpinned common biological dysfunction, and behavioral and cognitive features of individuals with ADHD. As most of the articles are methodologically cross-sectional, it is not possible to establish causative associations. Discussion and conclusion. This review points out the importance of early recognizing and treating circadian rhythms disorders and obesity in ADHD patients. Future studies must be carried out with a longitudinal design to establish the effect of each comorbidity in the treatment of individuals with ADHD.
