Filter by:Service members and/or recently separated veterans with post traumatic stress symptoms and mild traumatic brain injury may participate in 8 sessions including 2 sessions including interviews and questionnaires as well as 6 sessions of art therapy. In the art therapy, participants will be provided with a blank paper mache mask template and invited to alter the mask however they wish using a variety of art materials. The therapist will use the art-making process and culminating product to aid in self-reflection, reframe negative thoughts and feelings, and work through traumatic content. Prior to the session start participants will get set up with a mobile qEEG (worn like a hat and backpack). The qEEG will measure brain activity in a non-invasive way throughout the art therapy session to improve understanding of brain activity during the art therapy process.
Hypothesis 1: On fMRI scanning, frontoparietal activation during performance of executive function tasks of working memory, inhibitory control processes, and stimulus-response interference will exhibit greater signal intensity, a wider spatial extent, and more bilateral activation in chronic MTBI than chronic OI participants. Hypothesis 2: DTI changes, characterized by lower FA and higher MD at the gray-white junction, corpus callosum, central semiovale, and internal capsule, will be seen in MTBI but not in OI subjects. Hypothesis 3: Increased fMRI activation in chronic MTBI will be correlated with location and severity of disrupted fiber tracks that subserve neural networks associated with each fMRI activation task. Hypothesis 4: Performance on computerized neuropsychological testing (ANAM) and reaction time measures on fMRI tasks will better discriminate MTBI from OI than standard paper-and pencil tests. Hypothesis 5: The combination of fMRI, DTI, and ANAM will better discriminate MTBI from OI than each individual method. Hypothesis 6: More severe brain pathology in MTBI, as measured by neuroimaging (fMRI, DTI) and ANAM test scores, will be associated with less severe PTSD and symptoms.
We use Transcranial magnetic stimulation (TMS), combined with simultaneous registration of electroencephalograph (EEG),for examining human cortical functionality. TMS-EEG is a noninvasive brain stimulation method that allows to study human cortical function in vivo. EEG provides an opportunity to directly measure the cerebral response to TMS, measuring the cortical TMS Evoked potential (TEP). In this study we measure TEPs, in a wide variety of neurological conditions and healthy as a measure of cerebral reactivity across wide areas of neocortex.
The first aim of this study is to investigate the frequency and severity of a specific pathological metabolic pattern, mitochondrial dysfunction, of the brain in comatose patients under neurocritical care. This pattern is recognized as a complication after compromised blood flow to the brain and may be amenable to treatment. The other main aim of this study is to correlate patterns of metabolites between brain and jugular venous blood. It is probable but not proven that jugular venous microdialysis can mirror the global metabolic state of the brain.
SPECIFIC AIMS While post-concussive symptoms following sports-related concussion are typically transient and resolve spontaneously within two weeks of concussive injury, 14% or more of youth who sustain concussion experience significant morbidity that can persist well beyond the normal disease course.Furthermore, post-concussive symptoms commonly co-occur with affective symptoms including depression and anxiety which when present can prolong recovery from primary post-concussive symptoms. Together, persistent physical and psychological symptoms confer protracted functional impairment and create a significant burden for affected youth, their family, and school. Currently, there are no evidence-based guidelines to inform treatment of persistent post-concussive symptoms in youth and adolescents. In response to the dearth of evidence-based treatment approaches for youth with persistent post-concussive symptoms, the investigators developed a novel collaborative care treatment model that simultaneously targets post-concussive symptoms and co-occurring depression and anxiety. Athletes and their family members receive patient navigator care management services that bridge post-injury care across acute care, specialist and primary care health service delivery sectors, in addition to cognitive behavioral psychotherapy. Patients who remain symptomatic after initial treatment efforts receive stepped-up care that may include psychopharmacologic consultation. The Investigators have demonstrated feasibility of the intervention model through a pilot randomized-control trial of 49 adolescents with persistent post-concussive symptoms recruited from a regional children's hospital. Participants assigned to the intervention condition demonstrated significant and clinically-meaningful reductions in post-concussive and depressive symptoms as well as health-related quality of life as compared to adolescents in the usual care arm of the trial.
This retrospective study is a more extensive, confirmatory analysis of the cognitive and functional outcomes initially seen in 2 groups of MCI/dementia patients in Springfield, MA and compares specialized dementia care and a comprehensive treatment approach versus usual care delivered in a non-specialist setting. The first group of patients (n= 328) was seen by a dementia specialist, who utilized a standardized assessment and treatment protocol (CNS). This included comprehensive identification and treatment of hypoxia, sleep-disorders, and other cognitively-impairing metabolic conditions as well as maximally- dosed FDA-approved medications for dementia, depression, and PBA. The second group of patients (n= 280) was seen by non-dementia specialists in the community and received usual care which did not include comprehensive assessment or treatment of underlying metabolic derangements or maximal utilization of currently available medications. This study, evaluating date from a larger cohort (n>800) of specialist-treated cognitively-impaired patients, will further examine the hypothesis that a comprehensive dementia treatment protocol yields cognitive stabilization and/or improvement using already available dementia drugs when compared with usual community care.
The current study seeks to evaluate cognitive behavior therapy for insomnia (CBT-I), a non-medication treatment, in recent TBI patients compared to a sleep education control intervention. Patients will participate in CBT-I treatment (or sleep education treatment) weekly for six weeks, and will have a 3-months follow-up visit in order to examine the efficacy and time course of treatment. In addition, participants will complete several self-report questionnaires in order to examine sleep and neuropsychiatric symptoms throughout treatment.
The primary aim of this proposed study is to gather preliminary data for CES use in treating PTSD and anxiety symptoms in OEF/OIF Veterans with PTSD and a history of TBI.
Traumatic brain injury (TBI) is the most common cause of acquired disability in youth and a source of significant morbidity and family burden. Novel behavior problems are among the most common and problematic consequences, yet many youth fail to receive needed psychological services due to lack of identification and access. Linking youth with TBI to effective treatments could improve functional outcomes, reduce family burden, and increase treatment satisfaction. The investigators overarching aim is to compare the effectiveness, feasibility, and acceptability of three formats of family problem solving therapy (F-PST) for improving functional outcomes of complicated mild to severe adolescent TBI: therapist-guided, face-to-face; therapist-guided online; and self-guided, online F-PST.
Traumatic brain injury (TBI) affects 1.5 million patients per year in the United States, resulting in more than 50,000 deaths and more than 230,000 hospitalizations annually. Approximately 90,000 of these patients will suffer permanent impairment and more than half will experience short-term disability. Secondary injury processes play a critical role in the development of ischemia after trauma to the central nervous system and occur hours-to-days after the primary insult. Ischemia can lead to cerebral infarction or stroke. Ischemia has been described as the single most important secondary insult and has been identified histologically in approximately 90% of patients who die following closed head injury. Several factors resulting in post-traumatic cerebral ischemia have been identified: increased intracranial pressure (ICP), systemic arterial hypotension, and cerebral vasospasm. Cerebral vasospasm has been described as a sustained arterial narrowing. Clinically, the onset of new or worsening neurological symptoms is the most reliable indicator of cerebral vasospasm following a ruptured cerebral aneurysm. However, cerebral vasospasm is often unrecognized in patients suffering from moderate to severe TBI. These patients frequently have altered mental status due to the primary brain injury. In addition, they require narcotics for their pain and paralytics and/or sedatives while on a mechanical ventilator for airway protection. Thus, relying on the neurological exam to observe deteriorating neurological signs consistent with post-traumatic vasospasm (PTV) is reliable. While the etiology and outcome of patients with vasospasm secondary to ruptured aneurysm is well documented, the clinical significance of PTV after TBI is unknown. A better understanding of the role of cerebral autoregulation in the development of cerebral vasospasm could provide the answer. This proposal is for a pilot observational study describing the association of the impairment of cerebral autoregulation as measured by near infrared spectroscopy (NIRS) with the development of clinically significant vasospasm in patients with moderate to severe TBI. The information will serve as preliminary data for further study.
