“…There is increased evidence that disturbed or insufficient sleep can result in poor functioning in numerous domains, such as cognitive performance, motor function and mental health (Gregory & Sadeh, 2015;Miller et al, 2014). Sleep disturbances appear to be closely linked to psychopathology and are frequently reported by individuals with psychiatric disease (Abad & Guilleminault, 2005;Afonso, Brissos, Figueira, & Paiva, 2011;Benca, Obermeyer, Thisted, & Gillin, 1992;Krystal, 2006), making recognition and management of sleep disturbances an important step in improving treatment outcome and preventing mental illness relapse (Abad & Guilleminault, 2005;Ivanenko & Johnson, 2008).…”

“…Previous studies have demonstrated that sleep alterations, such as decreased total sleep time and sleep quality, increased nighttime wakefulness, and fragmented sleep are not only highly prevalent in MCI and AD patients [5–7] but also increase the risk for future cognitive decline when present in normal older adults [8,9]. Moreover, sleep influences not only cognition (for a review, see [10]) but also several cortical regions early affected by AD pathology, such as the medial temporal lobes (MTLs) [11,12] as well as other cortical regions [13]. The MTL consists of the hippocampus and its adjacent cortices (e.g., entorhinal, parahippocampal and perirhinal) [14].…”

Introduction Subjective cognitive decline (SCD) is a risk factor for mild cognitive impairment (MCI) and Alzheimer’s disease (AD). Although sleep has been shown to be altered in MCI and AD, little is known about sleep in SCD. Methods Seventy cognitively normal community-dwelling participants were classified as SCD (32) or controls (38) using the Subjective Cognitive Decline Questionnaire. Sleep was assessed using actigraphy and diaries. FreeSurfer was used for performing medial temporal lobes (MTLs) and brain cortical parcellation of 3T magnetic resonance images. Multiple regression models were used to assess the presence of sleep, MTL, or regional cortical differences between groups. Results Objective sleep was disrupted in SCD participants, which showed increased nighttime wakefulness and reduced sleep efficiency. No group differences emerged in subjective sleep or magnetic resonance imaging outcomes. Discussion Objective sleep resulted disrupted in community-dwelling SCD, without any subjective sleep or cortical change. Sleep assessment/intervention in SCD might help prevent/delay AD onset.

“…Penelitian lain menyatakan bahwa hubungan antara keluhan tidur dan penurunan fungsi kognitif akan hilang apabila faktor depresi dapat dikontrol, hal ini menimbulkan pertanyaan apakah kualitas tidur yang buruk menyebabkan secara langsung buruknya fungsi kognitif atau meningkatkan keluhan depresi yang pada akhirnya menyebabkan penurunan fungsi kognitif (Jelicic, 2002;Miller, 2014).…”

Elderly are often considered as a burden because of their physical limitations. The reduced cognitive function is one of the important causes for this physical limitation. Quality of sleep used to be associated with changes in cognitive function. A comparative analytic research to assess insomnia as a risk factor for the incidence of cognitive function impairment in the elderly. A case-control study in elderly community at the nursing home St.Yosef, Surabaya. Fifty respondents were taken by consecutive sampling and meeting the inclusion criteria. This study also excluded people with depression, schizophrenia, and users of psychotropic drugs. Eighty four percent of respondents have impaired cognitive function. Not much difference in percentage of insomnia disturbance in control group (37,5%) and case group (35,8%). Fisher's Exact Test show Sig.0,609 and OR=0.926 on CI [(0,194),(4,425)]. It was concluded that insomnia alone was not a risk factor for impaired cognitive modalities. Elderly exposed to sleep disorders have the same tendency to suffer cognitive impairment with unexposed. Keywords: Elderly, Impaired cognitive function, Insomnia Correspondence to : tmnitakurniawati@gmail.com, yudhiakuari@ukwms.ac.id ABSTRAK Seringkali lansia dianggap sebagai beban karena berbagai keterbatasan fisik yang mereka derita. Penurunan fungsi kognitif menjadi salah satu penyebab kondisi tersebut. Kualitas tidur diduga berhubungan dengan perubahan fungsi kognitif. Penelitian analitik komparasi untuk menilai insomnia sebagai faktor resiko kejadian gangguan fungsi kognitif pada lansia. Penelitian ini merupakan studi kasus kontrol pada komunitas lansia di Panti Werdha St,Yosef, Surabaya. Sampel diambil dengan cara consecutive sampling. Ditemukan 50 responden yang sesuai kriteria inklusi. Penelitian ini mengekslusi penderita depresi, dan skizofrenia, serta pengguna obat psikotropika. Ditemukan 84% responden dengan gangguan fungsi kognitif. Tidak banyak perbedaan persentase gangguan insomnia pada kelompok kontrol (37,5%) maupun kelompok kasus (35,8%). Hasil Fisher's Exact Test menunjukan Sig.0,609 dan nilai OR=0,926 pada CI [(0,194), (4,425)]. Insomnia secara tunggal bukan faktor resiko terjadinya gangguan modalitas kognitif. Lansia yang terpapar gangguan tidur mempunyai kecenderungan yang sama untuk menderita gangguan kognitif bila dibandingkan dengan mereka yang tidak terpapar.
