Aerobic exercise has emerged as an effective treatment to reduce sport-related concussion symptom severity, yet existing work lacks rigor regarding the precise exercise volume and intensity required to elicit therapeutic effects, how exercise can alter concussion-related pathophysiology, and whether exercise can prevent the development of secondary sequelae. Our objective is to examine if a high dose exercise program (higher volume than currently prescribed at an individualized, safe intensity level) initiated within 14 days of concussion results in faster symptom resolution, altered physiological function, or reduced secondary sequalae. Findings from this research will lead to more rigorous and precise rehabilitation guidelines and improved understanding about how exercise affects neurophysiological function among adolescents with concussion.

The goal of this clinical trial is to learn about cognition in psychotic disorders (schizophrenia, bipolar disorder, and schizoaffective disorder). The main question it aims to answer is: Can we use magnetic stimulation to change processing speed (how quickly people can solve challenging tasks). Participants will be asked to perform cognitive tasks (problem-solving) and undergo brain scans before and after transcranial magnetic stimulation (TMS). TMS is a way to non-invasively change brain activity. Forms of TMS are FDA-approved to treat depression and obsessive compulsive disorder. In this study, we will use a different form of TMS to temporarily change brain activity to observe how that changes speed in problem-solving.

Although there are an increasing number of mental health treatment adaptations for older adults, there are still a number of factors to consider when making these adaptations. Cognitive decline is one such factor that places significant burden on older adults and can interfere with traditional mental health therapies. Engage is a behavioral treatment approach that has shown to be effective in treating late life depression. The investigators are testing the feasibility of Engage as a treatment method for late life depression in older adults with cognitive decline. The objective is to corroborate Engage as an alternative late life depression treatment method for a sub-population of older adults with cognitive decline. Cognitive decline poses a unique mental health treatment barrier that is often over looked in younger populations. With a relatively higher prevalence of cognitive decline in older adulthood, it is imperative that a feasible mental health treatment program that can be effective in the presence of cognitive decline.

Herbal Medicine is known as the medicinal use of herbal substances as a means of treating different conditions in the human body to ensure that the body remains in optimal health and wellness. These substances are known to contain very active ingredients in it and as such is also a very potent means of managing diseases and ailments in the body. Herbal medicine has always been a standby source of getting relief from various conditions over centuries, however, it can be categorically said that the mode of usage of these herbal substances has changed over time. Traditional healers help individuals to make meaning out of the natural herbs seen around that can be useful to one's health. Herbal medicine is the use of plants to treat disease and enhance general health and wellbeing. Herbs can interact with other pharmaceutical medications and should be taken with care. Always seek a regular medical doctor (GP) about any health concerns and tell them about any herbal medicines you are taking or thinking of taking. Never stop taking prescribed medications in favor of herbs without first discussing it with your GP.

This protocol proposes an initial randomized clinical trial that includes all patients with suicidal ideation (SI) at baseline, and with SI as the primary outcome measure to examine whether Right Unilateral Low-Amplitude Pulse - Seizure Therapy (RUL LAP-ST) treatment has more magnitude and rate of remission of SI as conventional pulse amplitude Right Unilateral Electroconvulsive Therapy (RUL ECT) (based on our prior secondary analysis). Our central hypothesis is that RUL LAP-ST has significantly less cognitive/memory side effects (no memory side effects were noted in our prior studies for 500mA and 600mA) and thus is more favorable in terms of side effects compared to RUL conventional pulse amplitude ECT, while maintaining better anti-suicidal effect.

Despite medical advancements, PTSD remains a major issue in Veterans1. Current treatment strategies have relatively poor adherence. In patients with PTSD and cirrhosis, there is greater cognitive impairment as well as changes in gut microbiome structure and function2,3. In addition, when there is concomitant cirrhosis, medication-related treatment options become even narrower from a safety and tolerability perspective and cognitive issues pertaining to cirrhosis could impact participation3. Changes in gut microbiome in Veterans with cirrhosis and PTSD compared to those with cirrhosis without PTSD is characterized by a greater relative expression of pathobionts and reduction in stool microbiome diversity with reduction in bacteria that produce beneficial short chain fatty acids (SCFA)2. Modulation of the gut microbiome in patients with cirrhosis and PTSD may be an important therapeutic target. In prior studies with cirrhosis alone, microbial modulation using diet, antibiotics such as rifaximin, probiotics, and fecal microbiota transplant have improved gut microbial diversity and clinical outcomes in some cases4,5. In patients with cirrhosis without PTSD and in patients with PTSD without cirrhosis there is emerging evidence regarding prebiotics and other forms of gut microbial modulation. Prebiotics are such an example6. Prebiotics are natural fibers derived from carbohydrates and can be beneficial to gut microbiota (good bacteria in the gut)6. Resistant starches (RS) are dietary fiber prebiotics found naturally in many foods including potatoes, plantains, and legumes6,7. In addition to being highly accessible, RS have been shown to be well tolerated with few adverse reactions. While no studies of RS exist in PTSD + cirrhosis patients, a meta-analysis of RS in IBD has shown RS to be an effective treatment in both animal and clinical studies where improvements in clinical remission and reduced mucosal damage were found7. However, there is insufficient data regarding patients with PTSD and cirrhosis regarding gut microbial structure and function modulation with dietary supplements such as resistant starches. These starches can improve SCFA production in elderly subjects, which could in turn affect the gut-brain axis favorably8.

Deficits in motivation and pleasure are common in depression, and thought to be caused by alterations in the ways in which the brain anticipates, evaluates, and adaptively uses reward-related information. However, reward processing is a complex, multi-circuit phenomenon, and the precise neural mechanisms that contribute to the absence or reduction of pleasure and motivation are not well understood. Variation in the clinical presentation of depression has long been a rule rather than an exception, including individual variation in symptoms, severity, and treatment response. This heterogeneity complicates understanding of depression and thwarts progress toward disease classification and treatment planning. Discovery of depression-specific biomarkers that account for neurobiological variation that presumably underlies distinct clinical manifestations is critical to this larger effort.

The core objective of this study is to enhance the translational potential of this electroencephalogram (EEG) biomarker by using ketamine(KET)-induced gamma potentiation as a prognostic marker of 4-week treatment outcome. Previous research focused exclusively on KET-induced gamma band potentiation (GBP) in the context of a single infusion. Our study design captures the clinical variation associated with real-world treatment resistant depression (TRD) patients and allows us to analyze the relative importance of GBP to antidepressant symptom reduction across the induction phase of treatment. If successful, it provides a compelling rationale for a larger prospective investigation of gamma dynamics as a moderator of outcome to varied TRD therapies which impact the balance of cortical excitation and inhibition.
