Abstract INTRODUCTION Dreaming is subserved by the default mode network (DMN) and can be abolished by focal lesions within key regions. DMN dysfunction is promoted by pre‐clinical Alzheimer's pathology and apolipoprotein E ( APOE ) ε4 carriage, but any effects of these on dreaming are unknown. METHODS Associations between dream recall and APOE ε4 carriage and blood phosphorylated tau (p‐tau)...
Distressing dreams were previously reported to predict future all‐cause dementia among predominantly white US participants aged 79–89 years, particularly in men. We investigated whether disturbing dreams (nightmares and bad dreams) were associated with all‐cause and Alzheimer dementia (AD) among individuals aged 60–89 years from diverse international regions.
Abstract Background Evidence suggests that dreaming is subserved by the default mode network (DMN) (Domhoff, 2022. The Neurocognitive Theory of Dreaming ). β‐amyloid plaques and phosphorylated tau ( p ‐tau) protein tangles accumulate and contribute to abnormal functionality in the DMN long before clinical Alzheimer's disease, and similarly early abnormal DMN functionality is shown by...
Numerous theories of dreaming consider embodied self-representation and participation in dream events as key features. However, past studies suggest that the dream self is absent or an uninvolved observer in over 10% of adult REM dreams. Further, these dreams can be similarly elaborate and of comparable narrative structure to participatory dreams. The current study presents new criteria for...
Numerous theories of dreaming consider embodied self-representation and participation in dream events as key features. However, past studies suggest that the dream self is absent or an uninvolved observer in more than 10% of adult rapid eye movement dreams. The current study first presents new criteria for observer dreams that are informed and illustrated by reports from adult dream series....
