Active clinical trials for "Post-Concussion Syndrome"

Persistent-post-concussion symptoms (PPCS) is a condition that effects on average one in seven persons following a concussion. Anxiety and depression symptoms are experienced by over one-third of those with PPCS. These symptoms can delay recovery from a concussion. Two techniques used to treat anxiety and depression symptoms are breath control and mindfulness exercises. This 8-week feasibility study will evaluate the implementation and compliance of a remote delivered breathing and mindfulness treatment program for individuals experiencing PPCS anxiety or depression symptoms.

The current project will examine the effect of a brief psychological intervention on post-concussion symptoms, neurocognitive function, cerebral blood flow (CBF), and psychophysiological and salivary cortisol markers of autonomic nervous system (ANS) in a sample of 20 participants between 13-25 years of age who experience long-term post-concussive (PC) symptoms 2-9 months post-injury as well as 20 age- and sex-matched controls (non-injured) participants to provide normative data on all the above measures except for concussive symptoms.

PURPOSE: The long-term goal of this line of research is to develop rational, biologically based evidence for the treatment of post-concussion syndrome (PCS) in children. The objective of this application is to examine the effect of melatonin on the symptoms of PCS and its neurobiology using integrated neurodiagnostic techniques in children. OVERVIEW: PCS is a constellation of clinical symptoms including physical (i.e. headaches), cognitive (i.e. memory), and behavioral disturbances. PCS is associated with significant morbidity in the child and his/her family), and yet there are no evidence-based medical treatments available. This suggests an urgent need to develop novel treatment options to improve outcomes for children suffering from PCS. Melatonin has several relevant mechanisms of action, and neuroprotective effects. Recent research suggests that the explanations for persistent PCS symptoms may be due to alterations in neurotransmissions and neuronal circuitry, particularly involving the dorsolateral prefrontal cortex (DLPFC). Investigators have two specific aims: To determine if treatment with melatonin improves PCS in children following mild traumatic brain injury. Hypothesis: treatment of mTBI children with PCS with 3mg or 10mg of oral melatonin for 28 days will result in a decrease in PCS symptoms as compared with placebo. Effects will be dose-dependent and may be independent of sleep effects. Methods: A randomized double blind, placebo controlled trial (RCT); Outcome measure is a PCS symptom questionnaire. A subsequent RCT will then be performed using the optimal melatonin dose at a second centre. To understand the neurophysiological mechanisms of paediatric PCS and assess any resultant effects of treatment with melatonin. Methods: A case-controlled study within the RCT, using functional MRI and Transcranial Magnetic Stimulation to investigate the neurophysiological properties of paediatric mTBI before and after treatment; Treatment groups from the RCT will be compared with two control groups: i) normal controls and ii) asymptomatic mTBI children. SIGNIFICANCE: This study has the potential to 1) provide a safe and effective treatment for PCS and 2) will provide valuable information about the neurophysiological properties of the brain associated with PCS following mTBI in children and how these change with symptom resolution.

Although the vast majority of individuals sustaining a sport-related concussion (SRC) will receive medical clearance to return to sport within 7-10 days, approximately 30% of children and adolescents reporting to the emergency department will experience symptoms that last longer than a month. Research has demonstrated that exercise below the threshold that results in increases in symptoms, beyond those experienced at rest, (sub-symptom threshold aerobic exercise) may be beneficial in recovery. However, the optimal amount and intensity of aerobic exercise for an individual to experience the most beneficial outcomes is currently unknown. Unfortunately there are limited Randomized Controlled Trials (RCT's) evaluating the benefits of aerobic exercise in a youth population. The current evidence includes studies with relatively small sample sizes, unreliable measurements of physical activity (self-report), and inherent biases through inadequate blinding. There is a need to develop and validate evidence-informed interventions as a means of treatment for limiting time loss from sport, and school in adolescents who experience persistent symptoms of sports related concussion beyond 10 days.

Preliminary clinical evidence suggests that Service Members with symptoms of post-traumatic stress disorder (PTSD) or Post Traumatic Stress (PTS) who participate in the Service Dog Training Program (SDTP) report improved physical and psychological outcomes, including those with overlapping symptoms associated with traumatic brain injury (TBI) and post-concussion symptoms (PCS). This study intends to examine the psychological, social, and biological effects of learning how to train a future service dog combined with standard of care for individuals with symptoms of Post-Traumatic Stress (PTS), including those with overlapping TBI and persistent Post-Concussive Symptoms (PCS). Biological, social, and behavioral measures will be collected throughout study participation.

The primary purpose of this study is to investigate the effectiveness of a brief mindfulness-based intervention for targeting chronic physiological underarousal and post-concussive symptoms following a mild head injury (MHI), as self-reported by undergraduate university students. For the purposes of this study, MHI is defined (and identified) through our demographic questionnaire as a traumatic-based injury to the head - "Have you ever hit your head with a force sufficient to alter your state of consciousness" (consistent with the Kay et al., 1993 criteria/definition; American Congress of Rehabilitation Medicine - ACRM). The investigators exclude congenital or genetic injuries.

Concussion is defined as any temporary disturbance in brain function following a blow to the head. It may not involve a loss of consciousness and usually results in a post concussive headache (PCH) immediately after the injury. Between 30 and 50 percent of patients with concussion will develop postconcussive syndrome (PCS) consisting of symptoms such as headache, and a variety of other debilitating symptoms lasting several weeks to months. The objective of this study is to determine if metoclopramide, a drug commonly used in the treatment of migraine headache, will be effective in relieving PCH and in preventing PCS. Eligible patients will have a history of a concussion resulting in headache within the past 24 hours. Patients will rate their pain on a standard scale before and after being treated with one or two intravenous doses of either metoclopramide or saltwater placebo. They will be contacted by telephone 1, 4 and 8 weeks later in order to determine if they have developed the postconcussive syndrome.

The study will ask the question as to whether or not it is possible to deliver education material to patients with a mild traumatic brain injury in a consistent matter. The question will be asked as to whether an educational intervention decreases symptom reporting specifically looking at headache symptoms. Half of the patients will receive the current standard of care in the tertiary clinic they have been referred to while the other half will also receive the current standard of care with the addition of targeted headache educational material at various time points.

Objective/Hypothesis: An eight-week course of forty low-pressure Hyperbaric Oxygen Treatment's (HBOT's) can significantly improve symptoms and cognitive function in subjects with the persistent-post concussion syndrome (PPCS) of mild traumatic brain injury (mTBI).

It has been suggested that activity immediately following concussion is detrimental to recovery and may lead to long term impairments. The animal model has shown that exercise too soon can lead to neurometabolic energy imbalances within the brain. However, there is also evidence to suggest that prolonged inactivity has negative consequences that may contribute to prolongation of symptoms. Determining the ideal timeframe in which to initiate an active rehabilitation protocol for patients who are slow to recovery is an important factor in concussion management.
