Circadian rest/activity rhythms and change in MRI‐derived brain volumes: Differences by age in a cognitively healthy sample

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Circadian rest/activity rhythms (RARs) change across adulthood, and alterations in RARs have been associated with cognitive decline, Alzheimer's disease (AD), and dementia. Little is known, however, about associations of RARs with subsequent changes in brain structure.

Glial cytokine modulation improves sleep and circadian disruption in female SAA knock‐in mice of Alzheimer's‐related pathology

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Sleep and circadian disturbances are early Alzheimer's disease (AD) features, yet mechanisms linking amyloid pathology, neuroinflammation, and sex differences remain unclear. METHODS We longitudinally assessed sleep, circadian rhythms, and cognition in female and male hAPPSAA knock‐in and control mice from 2 to 19 months using ...

Associations between sleep disturbance and cerebrospinal fluid Aβ, and shared proteomic signatures in Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Sleep disturbance is increasingly recognized as a risk factor for Alzheimer's disease (AD), but longitudinal clinical evidence linking sleep behaviors to cerebrospinal fluid (CSF) amyloid beta (Aβ) dynamics and related proteomic signatures remains limited.

Home‐based sleep monitoring reveals associations between amyloid accumulation and sleep alterations in individuals with subjective and mild cognitive impairment

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Sleep disturbances have been associated with Alzheimer's disease (AD), but their relevance in preclinical stages, such as subjective cognitive decline (SCD), and their relationship with brain pathology remain unclear. METHODS We used a portable sleep‐monitoring headband over four consecutive nights to assess sleep in 19 ...

Midlife sleep characteristics and Alzheimer's disease biomarkers 20 years later

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Poor sleep characteristics are associated with Alzheimer's disease (AD) among older adults; however, this relationship remains underexplored earlier in life. We investigated how early midlife sleep relates to AD‐related biomarkers in late midlife.

The Canadian multi‐ethnic research on aging (CAMERA) study: Design, participant characteristics, and preliminary findings

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION South Asian and Chinese individuals are the largest and fastest‐growing ethnoracial groups in Canada, yet they remain underrepresented in dementia research. To address this gap, we established the CAnadian Multi‐Ethnic Research on Aging (CAMERA) study.
