Many older adults start to experience poorer sleep quality as they age, which can be associated with worse memory and cognition. Previous studies have shown that sleep can be improved when quiet sounds are presented at the right times during slow-wave sleep. We are interested in whether we can improve sleep and associated memory and cognitive function using these sounds in older adults. Information gathered from this study will be used to inform whether quiet sounds presented during slow-wave sleep can improve sleep, memory, and cognitive function.
Are 60 and older with and without mild cognitive impairment (MCI) You must be able to read, speak, or understand English.
If you do not have:
1) major psychiatric or neurological disorders
2) moderate to severe depressive or anxiety symptoms
(3) sleep disorders
(4) serious medical illness
(5) known stroke or transient ischemic attack
(6) alcohol or substance abuse
(7) a history of seizures
(8) chronic use of psychoactive or hypnotic medications, or use of any medication that alters sleep
(9) significant hearing loss or hearing aid use
(10) untreated moderate or severe sleep apnea on a home sleep apnea test.
Participants with well-controlled sleep apnea will be eligible to participate provided they are able to use their CPAP machine or other treatment device throughout the study
Thinking skills (also known as cognitive functions), change from younger to older adulthood. In this study we are investigating how these shifting architectures of cognition and brain function relate to one another, and how these brain and cognitive changes impact decision-making in younger and older adults.
You may qualify to participate if you are: 1) 60 years of age or older, 2) right-handed, 3) in good health, 4) and have normal or corrected-to-normal vision. Participation will involve completing cognitive tasks, questionnaires, and non-invasive brain measurements using MRI. If you are interested in participating in this study, please contact lbc.spreng@gmail.com
You are eligible to participate if you:
- Are aged 60 years or older
- Are right-handed
- Are cognitively healthy
- Are able to come in-person to our site, located at the Montreal Neurological Institute
- Have no metal in your body (e.g., pacemaker, metal plates, orthopedic devices, etc.)
- Speak English or French
This study will uncover how bilingualism supports healthy cognitive aging by examining the influence of different language experiences on the timing and location of brain network activity. We will examine the timing of brain activity using electroencephalography (EEG; i.e., recordings of electrical brain activity) and the location of brain activity using magnetic resonance imaging (MRI; i.e., images of activity in different parts of the brain). Different language experience factors will additionally be explored. By measuring multiple factors (e.g., the age of second language learning, language proficiency) the effect(s) of different language experiences on the brain and cognition will become clearer.
You are eligible to participate if you:
- are a French-English bilingual over the age of 65
- have mild cognitive impairment
- have Alzheimer's disease
- are a healthy older adult (i.e., have no cognitive conditions)
Please note that you do not need to be completely fluent in both English and French, just to have some familiarity, experience or training with both languages to be eligible to participate.
Thank you for your consideration!
CAN-PROTECT is a Canada-wide online study recruiting participants and caregivers of persons with dementia to explore how lifestyle, background, and caretaking factors affect our health, quality of life, cognition, behaviour, and function as we age. CAN-PROTECT data will be analyzed and jointly published by the University of Calgary in partnership with the University of Exeter.
- Age 18 years or older
- Reside in Canada
- Have access to a computer/touchscreen device
- Can provide informed consent
- Do not have a diagnosis of dementia
- Additionally, we are enrolling participants who have previously or currently care for persons with dementia for caregiver-specific assessments
- Ability to speak English
Our study titled "Investigating the Role of Quantitative Susceptibility Mapping and Oxygen Extraction Fraction as Advanced Neuroimaging Biomarkers in Alzheimer's Disease" aims to develop non-invasive diagnostic biomarkers for Alzheimer's Disease (AD). We focus on evaluating the potential of QSM and OEF to differentiate between AD, Mild Cognitive Impairment (MCI), and Cognitively Unimpaired populations and to predict amyloid and tau pathology, using a Systems Biology approach. Leveraging the McGill University's TRIAD cohort, the study utilizes advanced imaging and machine learning to predict amyloid and tau presence, which could transform AD diagnostics and treatment. Methodologically, it involves preprocessing neuroimaging data and employing machine learning classifiers to analyze these features. The anticipated outcomes include validating QSM and OEF as non-invasive biomarkers for AD, establishing their correlation with amyloid and tau proteins, and developing predictive models for clinical decision-making, potentially resulting in significant advancements in AD diagnostics.
Are a member of the TRIAD cohort at McGill University, falling within one of the following categories: young control, cognitively unimpaired, mild cognitive impairment, or Alzheimer's Disease.
Are willing and able to undergo advanced neuroimaging techniques including MRI and PET without contraindications.
Have not had any significant neurological conditions (other than AD for the AD group) that might interfere with the results of the study.
Have no metal implants, devices, or other conditions that may contraindicate or distort MRI imaging.
Are not currently participating in other clinical trials or studies that involve interventions which might interfere with the results of this study.
Are able and willing to provide informed consent for participation in the study or have a legally authorized representative who can do so.
Do not have a history of substance abuse or other conditions that might confound the imaging and cognitive data.
Have not undergone any significant head trauma or surgery in the past 6 months.
Are not pregnant or planning to become pregnant during the duration of the study.
Are willing to comply with all study-related procedures, imaging sessions, and follow-up evaluations.
Ability to speak English and French
The aim of our study is to better understand whether certain lifestyle factors (such as physical activity and hearing) are related to early changes in memory and thinking abilities in older adults. We are especially interested in enrolling individuals who are South Asian or East Asian, because little research has focused on brain health in Canadians of diverse racial/ethnic backgrounds.
By participating, you will help us better understand how lifestyle factors are related to memory and thinking changes in adults from diverse communities. We hope that this will lead to improved prevention and early intervention strategies for dementia.
You are eligible to participate if you…
- Are 55-85 years old
- Have no major medical or psychiatric diagnoses
- Are comfortable speaking and reading English
- Are able to undergo an MRI scan
-Speak English
Eligibility is dependent on an additional conversation with the study team.
