Modafinil's Effects on Cognition in Remitted MDD
Major Depressive DisorderCognitive ImpairmentCognitive difficulties such as indecisiveness or inability to concentrate are core symptoms of depression with up to 90% of untreated depressed individuals experiencing these symptoms. As many as half of those who remit from a major depressive episode continue to experience residual cognitive deficits, but these symptoms are frequently overlooked in clinical practice. This leads to persistent cognitive deficits which can cause reduced level of functioning and loss of productivity. As standard antidepressants have an inadequate impact on these residual cognitive symptoms, further treatment options are required. Modafinil is a wakefulness agent with evidence that it improves some domains in cognition such as memory in those whose non-cognitive depressive symptoms have been treated over a short term period. This medication may have favourable lasting effects on cognition, such as the ability to plan and execute tasks in those who receive modafinil for a longer time period. The aim of this study is to investigate whether modafinil can enhance cognition and have additional effects on functioning and work productivity in a sample of participants who were treated for depression but who continue to experience cognitive deficits.

Study With Lu AF20513 in Patients With Mild Alzheimer's Disease (AD) or Mild Cognitive Impairment...
Alzheimer DiseaseThe purpose of this study is to study the effect of monthly dosing with a single dose of Lu AF20513, with and without booster vaccine, on antibody response.

CNS Tau Kinetics in Healthy Aging and Alzheimer's Disease
Alzheimer's DiseaseBrain Diseases10 moreAlzheimer's disease (AD) is the most common cause of dementia and currently has no disease modifying treatments or simple accurate diagnostic tests. The goal of this project is to study how tau (a protein thought to cause AD) is made, transported and cleared in the human body. Better understanding of these processes may lead to improved understanding of AD, earlier diagnosis and a way to evaluate treatment.

An Online Cognitive Assessment in Cancer Patients
Cancer-Related Cognitive DifficultiesCancer-Related Cognitive ImpairmentThe purpose of this study is to test the feasibility (acceptability and usability) and usefulness of the CAMPFIRE (Cognitive Assessment and Monitoring Platform for Integrative Research) system, a patient-facing portal able to collect and produce reports for clinicians on Patient Reported Outcome Measurement Information System (PROMIS-Cognitive Function/Anxiety/Depression) outcomes via MyChart and NIH Toolbox, an inperson brief objective cognitive function battery. This study will aim to determine the value of the CAMPFIRE system for patients and providers as a tool for monitoring cognitive symptoms throughout the course of chemotherapy

Early Detection of Neuropathy and Cognitive Impairment Following Treatment for Haematological Malignancies...
Chemotherapy-induced Peripheral NeuropathyChemotherapy-induced peripheral neuropathy (CIPN) is a common, but not well understood complication to treatment with chemotherapy. In this study the investigators will investigate a novel method for early detection of CIPN and compare it to other methods in patients treated for haematological cancers.

Quetiapine XR for Cognitive and Functional Disability in Clinically Stable Patients With Bipolar...
Bipolar DisorderCognitive ImpairmentQuetiapine has been reported to have beneficial cognitive effects in several randomized controlled trials in schizophrenia. It has not yet been studied in bipolar disorder, but promising results from the use of extended release quetiapine for the maintenance treatment of bipolar disorder suggests that its cognitive benefits could be detected. Moreover, quetiapine has been shown to have direct beneficial effects on performance-based measures of social competence in schizophrenia and to improve quality of life (QoL) in bipolar depression. The investigators propose to study quetiapine augmentation of mood stabilizer monotherapy in clinically stable patients with bipolar disorder. This will be a randomized, placebo controlled trial, with attentional impairments as the primary outcome and other cognitive performance variables and measures of social and everyday living skills, as well as subjective QoL, as the secondary outcomes.

Educational and Cultural Engagement and Incidence of Health Adverse Events

Association of Centre of Excellence Self- Administered Questionnaire Score and Frailty Levels
FrailtyCognitive Decline2 moreThis study evaluates the frailty and the health adverse events in the population of the Canadian Longitudinal Study on Aging. It will be used the Centre of Excellence Self-Administered questionnaire (CESAM) which assesses frailty of older adults by providing a score and a of frailty in 4 levels.

Does Acoustic Stimulation During Sleep Boost Slow Wave Sleep and Memory Performance?
HealthyMild Cognitive Impairment1 moreWith aging the amount of slow wave sleep decreases drastically and this disruption is markedly exaggerated in older adults suffering from mild cognitive impairment and Alzheimer's disease. Critically, the disruption of slow wave sleep and cognitive decline seem bidirectionally linked forming a vicious cycle. In the long run, improving slow wave sleep might be a useful intervention tool to delay the onset of cognitive decline. The present study aims at improving slow wave sleep and memory functions through a closed-loop acoustic stimulation approach. A closed-loop algorithm is used that detects slow waves in the electroencephalogram and is programmed to present short tones (50 ms) in the rhythm of these waves. This procedure has shown to boost both slow wave sleep as well as memory performance, mainly in young adults and when applied for one night. Here, the investigators apply tones via multiple consecutive nights and assess memory performance during this 3-night intervention.
