In several cross-sectional and prospective studies, sleep apnea, sleep disordered breathing, habitual snoring, insomnia, difficulties in initiating and maintaining sleep, and daytime sleepiness have been associated with the prevalence and the incidence of type 2 diabetes (1– 6).
We studied whether subjective complaints of sleep apnea (habitual snoring and sleep disordered breathing), insomnia (difficulties in initiating and/or maintaining sleep), and daytime sleepiness were associated with IR and insulin secretion in a population-based sample of 18 75-year-old 18 75-year-old 18 75-year-old a history oFinnishncurrently diagnosed type 2 diabetes.
The case and control groups were identified based on their answers to questions as to overall insomnia, onset insomnia (difficulty in falling asleep), middle insomnia (difficulty in maintaining sleep or returning to sleep after awakening in the middle of the night), and terminal insomnia (early awakening in the morning).
Other symptoms he exhibited included hypervigilance, insomnia, difficulty concentrating and avoidance of conversations related to the war episode when he was imprisoned.
In most adults who experience daytime sleepiness, there is no problem with falling asleep at night, and in most adults with initiation insomnia, difficulty falling asleep at night is often associated with higher levels of arousal and hence daytime alertness.
So far, insomnia (difficulty initiating and maintaining sleep) has received very little attention in relation to body mass index (BMI) in the literature, but has been associated with BMI in young females [ 15].
Similarly, insomnia (difficulty falling asleep, staying asleep, waking up before the desired time and being left tired during the day) in RTx candidates [ 12] has a prevalence of 15% in patients on maintenance dialysis, compared to 8% post-RTx [ 13].
Regarding specific reports of insomnia symptoms: difficulty initiating sleep, difficulty maintaining sleep, and early morning awakenings, rates for White men and women were 41%, 75%, and 46%, respectively, whereas for their Black counterparts, rates were 14%, 37%, and 17% respectively.
6 Older individuals, who are most susceptible to PHN, are at greater risk for complications such as fatigue, anorexia, weight loss, insomnia, depression, difficulty concentrating, and difficulty performing activities of daily living.
Approximately 30%% of subjects reporting insomnia had difficulties initiating sleep.
Circadian disruption, sleep onset insomnia and difficulties in maintaining sleep in schizophrenic patients could be partly related to a presumed hyperactivity of the dopaminergic system and dysfunction of the GABAergic system, both associated with core features of schizophrenia and with signaling in sleep and wake promoting brain regions.
