This is an observational study evaluating the safety and efficacy of dronabinol for the treatment of anxiety and/or depression in older adults. Participants who are prescribed dronabinol as part of a voluntary inpatient stay in McLean's Division of Geriatric Psychiatry will be interviewed about their mood and cognition on a weekly basis while on dronabinol.
Social networks, social capital, i.e., network-accessed resources, and neighbourhood environments have been shown associated with a range of health behaviours and conditions, including obesity, physical activity, nutrition, and mental health. Research on social capital and health in Montreal has shown the importance of network social capital for a person's subjective health status, sense of control, self-reported physical activity, and obesity. Research has also shown high social capital to reduce health service use, mental health service use, and improve the management of chronic illnesses. Despite advances in the understanding of social capital and its link to health and health service use, most research on social capital is cross sectional and is unable to identify the causal pathways linking social networks and capital to health and health care use. Longitudinal research would strengthen the evidence base for designing interventions to prevent or delay the use of health services, particularly in older adults. This research has three main objectives: (1) transform the original sample of Montreal Neighbourhood Networks and Healthy Aging (MoNNET-HA) households (n=2707) into a panel study, (2) link the MoNNET-HA participant data to their Quebec Health Insurance Registry (Régie de l'assurance maladie (RAMQ)) information, and (3) assess the feasibility of extending the MoNNET-HA panel by one wave to include participant's core network members. Unique about the original MoNNET-HA sample is that it purposefully oversampled older adults (> 64 years old) but remains representative of Montreal adults at various ages and income levels. In addition, MoNNET-HA data is integrated into a GIS database which allows researchers to examine the effects of neighbourhood environmental characteristics on health. By linking MoNNET-HA data to RAMQ, researchers will be able to examine patterns of diagnosed health conditions, (e.g., fractures, depression), pharmaceutical use and adherence, and formal health care use over time. Transforming the cross-sectional study into a panel study would also allow researchers to examine longitudinally the dynamics of health and health care utilization among Panel participants over the life course, and the causal pathways linking neighbourhoods and networks to health and health care use.
The investigators aim to use a CES (cranial electrotherapy stimulation) intervention to improve emotional well-being by reducing symptoms of anxiety and depression and to assess for changes in markers of cellular health - specifically, telomere length and telomerase activity
Late-life depression affects 2-8% of seniors and causes high rates of caregiver distress and risk of suicide. To exacerbate the problem, antidepressants, the cornerstone of therapy, are resistant in 55-80% of this population. Hence, this group of patients is labeled as having treatment-resistant late-life depression (TR-LLD). Non-pharmacological interventions like meditation could offer significant benefits as augmentation strategies to improve response rate of antidepressants in TR-LLD. One such breath-based meditation intervention called Sudarshan Kriya Yoga is of interest based on highly significant preliminary data in adult patients with treatment-resistant depression, its scalability and relatively low cost to learn this lifelong skill. Thirty patients diagnosed with TR-LLD will learn this intervention over 5 consecutive days by a certified para-professional trainer. This will be followed by 3 weekly 90 min follow-up sessions and then bimonthly sessions for 8 more weeks. SKY consists of a series of breathing techniques, including Sudarshan Kriya (SK), a sequential rhythm-specific breathing exercise. Participants will be asked to practice this technique for 25-30 minutes daily over the next 11 weeks. The investigators will collect clinical as well as feasibility outcome measures. The investigators will also explore if it is feasible to assess the antioxidant Glutathione (GSH) in the brain using a sophisticated magnetic resonance spectroscopy. The investigators suspect that GSH levels are reduced in TR-LLD and they will improve with SKY.
The proposed study seeks to obtain preliminary signal of the tolerability and efficacy of transcranial direct current stimulation (tDCS) for depressive symptoms in a sample of adolescents with depression and epilepsy. Additionally, effects of tDCS will be assessed via electroencephalographic, cognitive, and psychosocial measures.
The proposed study will assess the combined effect of perampanel and ketamine on the anti-depressant response in individuals with treatment resistant depression. The purpose of this study is to test the hypothesis that stimulation of Alpha-Amino-3-Hydroxy-5-Methyl-4- Isoxazole Propionic Acid receptors (AMPAR) is critical to the anti-depressant response of ketamine.
The Center for Mind -Body Medicine has developed a mind-body skills group program that incorporates meditation, guided imagery, breathing techniques, autogenic training, biofeedback, genograms, and self-expression through words, drawings, and movement. These mind-body skills are designed to increase self-awareness and self-regulation. This program has been shown to significantly improve depression symptoms in children and adolescents with posttraumatic stress disorder in Gaza, but it has not yet been tested in a US adolescent population. The purpose of this study is to determine the feasibility of using mind-body skills groups to reduce depression in adolescents and to investigate the effects of the program on factors such as self-efficacy, mindfulness and rumination which are likely to mediate improvement.
Depression is a major health challenge, and despite developments in pharmacotherapy and psychotherapy a substantial part of patients will only recover very slowly and incompletely, and 10-25 % of the patients are resistant to treatment. Therefore, new treatment initiatives are in demand. Chronotherapeutics can regulate diurnal rhythms and sleep, and have shown promising results on antidepressant effects. Among chronotherapeutic treatment modalities, Bright Light Therapy (BLT) has been used in treatment of depression and sleep disorders for several decades with both an antidepressant and a sleep improving effect. BLT has also been shown to augment antidepressant therapy. Objectives. The objective of this trial is to investigate the feasibility of a combination of LED-light armatures aiming to mimic sunlight, when installed in the patient rooms of a psychiatric inpatient Ward. Investigators has opted for using a randomized design that will subsequently be tested in a larger clinical trial with depression severity as the primary outcome. In this feasibility study investigators will register the stability of the system, the influence of the light on patients regarding tolerability, comfort, depression level, and sleep. Investigators also so want to measure and collect specific light-data on the Non-image-forming light (NIF) by using specially designed light sensors to capture the spectral distribution of the light. Finally investigators will test the electronic case report form (eCRF) that has been designed for the trial. Design. The design is a randomised controlled feasibility trial with two arms: an active dynamic light trial arm and a standard light trial arm with blinding of depression outcome assessors (Hamilton depression rating scale), data collection, and data analyses. Randomization will be with a rate for active and standard of 2 to 1.
The long term follow up of a pilot study in which the invesitagors proposed to test whether high frequency stimulation of the subcallosal cingulate (SCC) is a safe and efficacious antidepressant treatment in five TRD patients, to compare the effects of left-sided vs. right-sided stimulation, and to investigate potential mechanisms of action of this intervention. Importantly, this study will be used to assess the need for and assist in planning a larger, more definitive trial of SCC DBS for TRD.
The aim of this study is to analyze both depressive symptomatology and psychological well-being fluctuation in a day-to-day basis in the general population, in order to identify contextual determinants of the mood and well-being changes
