“…Of interest, a higher percentage of middle‐aged men than middle‐aged women showed a PLMSI >5. The observation has been reported by several other researchers,27, 28, 41, 42 but not by all 13, 24, 25. To date, studies have shown that dopamine declines with age similarly in both men and women 38, 39.…”

Effects of periodic leg movements during sleep in middle‐aged subjects without sleep complaints

Recent reports have called into question the relevance of periodic leg movements during sleep disorder (PLMSD) as a specific clinical entity. Because periodic leg movement in sleep index (PLMSI) increases with age, it has become an important exclusion criterion in research on aging. However, it is unknown if PLMSI is related to sleep quality in middle-aged subjects without sleep complaints. The sleep of 70 healthy, middle-aged subjects (age 40 to 60 years) without sleep complaints was evaluated. Subjects were divided into two groups according to their PLMSI severity: (1) 43 subjects (28 women, 15 men) were in the low PLMSI group (<5) and (2) 22 subjects (9 women, 13 men) were in the high PLMSI group (>10). A significantly higher proportion of men than women showed PLMSI greater than 5. There was no significant effect of PLMSI severity group for polysomnographic sleep parameters. PLMSI exerted a small but significant effect on subjective sleep quality, especially in middle-aged men. These results raise questions about the relevance of PLMSI as a pathological index for middle-aged subjects without sleep complaints and support the notion that an increase in PLMSI may be part of the normal process of aging associated with the loss of dopaminergic function.

“…The role of other diagnostic tools such as actigraphy is limited. Although several studies have demonstrated that actigraphy is a sensitive and specific measure of PLMS in adult population, [58][59][60] it is insufficient in making an accurate assessment of PLMS in children. 61 Because most children with RLS and PLMD have evidence of low iron stores, it is important to obtain iron profiles including complete blood cell count, serum iron levels, and serum ferritin levels.…”

“…The significance of PLM is controversial as the presence of PLM does not always correlate with daytime sleepiness and poor sleep quality [14][15][16][17][18]. PLM can be asymptomatic, but those that disrupt sleep can result in clinical problems similar to RLS [19].…”

Sleep-associated movement disorders are a broad group of sleep disorders characterized by involuntary movements that may disrupt sleep. Relatively little is known about the clinical consequences of sleep-associated movement disorders on cardiovascular health. Because these disorders manifest mostly during sleep, recognizing a movement disorder can be particularly difficult. Nevertheless, patients can have frequent arousals and suffer from similar sleep deprivation, fragmentation, and autonomic disruption as occurs in sleep-disordered breathing. Subsequently, these disorders may have a serious impact on daytime function and perception of health in patients with chronic heart failure.
