Background: REM sleep behavior disorder (RBD) is characterized by loss of normal muscle atonia during REM sleep, often associated with dream enactment behaviors, and is typically a prodromal neurodegenerative condition in middle-aged and older adults. However, emerging case reports and case series suggest that not all RBD presentations follow this trajectory, particularly in younger...
Abstract Background Dream enactment behavior is a common feature of rapid eye movement (REM) sleep behavior disorder (RBD); however, there has been surprisingly little focus on sex differences in dream characterization in RBD. This is important to evaluate further, as it is possible that females and males have different dream characteristics in RBD, and screening questionnaires that focus on...
Abstract Introduction REM sleep behaviour disorder (RBD) is strongly associated with neurodegenerative disease (NDD), and the isolated form is a known prodrome of several alpha-synuclein-related NDD’s. RBD is difficult to diagnose, and screening questionnaires focus on vivid and aggressive dream content, but these characteristics may be more common to males, leading to underdiagnosis of RBD in...
The human brain displays a rich repertoire of states that emerge from the microscopic interactions of cortical and subcortical neurons. Difficulties inherent within large-scale simultaneous neuronal recording limit our ability to link biophysical processes at the microscale to emergent macroscopic brain states. Here we introduce a microscale biophysical network model of layer-5 pyramidal...
Background: Mindfulness-based stress reduction is an efficacious treatment for people with chronic health problems; however, it is highly intensive and time-consuming, which is a barrier for service provision. Objective: This study aims to develop an internet-delivered adapted version of mindfulness-based stress reduction for people with multiple sclerosis to make the intervention more...
People diagnosed with Parkinson's disease (PD) frequently experience visual and non-visual hallucinations often with comorbid psychosis, however, there is currently no gold standard tool for accurately assessing these symptoms. To address this problem, we designed a novel questionnaire to evaluate the presence of hallucinatory and psychotic symptoms in PD, as well as related symptoms, such as...
