Concussion Treatment in Older Adults

The purpose of this study is to conduct the first randomized control trial for targeted treatments for concussion in adults 50 years or older. Participants will be enrolled at their first concussion clinical visit (V1) and their second study visit will occur after (up to 7 days) or concurrently with the participant's second concussion clinical visit, typically (but not limited to) between 21-31 days from V1.

Although concussion is a common occurrence in older adults, we know little about the injury in this at-risk population. Certain management tools that might be appropriate for adolescent and young adult populations may not be appropriate for use in older adults who may have sensory, cognitive, and neuro-motor limitations. This study will help to develop initial evidence for targeted treatments for concussion in older adults. The study will utilize a two group design with permuted block random assignment to intervention and usual care/control groups. All participants will complete the following assessments at their initial and follow-up visit appointments: cognitive screening (learning, memory, language, executive functioning), concussion and mood symptom questionnaires, and neuro-motor screening. The primary outcomes for this study will be total symptom severity score (i.e., symptom burden) on the Concussion Clinical Profiles Screening (CP Screen) and Patient Global Impression of Change (PGIC). Secondary outcomes will include: Short Falls Efficacy Scale (SFES), Dizziness Handicap Inventory (DHI), Patient Health Questionnaire-9 (PHQ-9), Patient Health Questionnaire-15 (PHQ-15), Generalized Anxiety Disorder - 7 (GAD-7), Posttraumatic Stress Disorder Checklist (PCL-5), Pittsburgh Sleep Quality Index (PSQI), Neuro-Quality of Life (QOL) v2.0 - Cognition Function (Short version), Headache Impact Test (HIT-6), ID Migraine, Neck Disability Index (NDI), Vestibular Ocular Motor Screen (VOMS), Timed-Up-and-Go (TUG), Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). All outcomes will be treated as continuous.

One group receives basic behavioral management strategies. The second group gets targeted treatment strategies dependent on the concussion symptoms they are expressing.

Participants randomized to the behavioral control group will receive standardized (i.e., all participants in this group will receive the same interventions) behavioral management strategies that include activity, hydration, nutrition, sleep, and stress management strategies.

Participant receives exercises or strategies based on their clinical concussion domain given to them by their neuropsychologist: 1) Anxiety/Mood, 2)Headache/Migraine, 3)Vestibular, 4)Ocular, 5)Cognitive.

Participants will receive standardized behavioral management strategies for their concussion symptoms including: activity, hydration, nutrition, sleep, and stress management strategies. These strategies provide general methods to manage concussion symptoms and regulate daily activities to assist in the recovery of concussion.

Participants will be prescribed one or more interventions, tailored to their domains. Anxiety/Mood-Cog beh therapy(CBT) for maladaptive beliefs/avoidance/coping behaviors. Graded exposure/activity/relaxation exercises, cognitive restructuring. Cognitive-Accommodations for reduced work/school time/delayed deadlines, more frequent/longer cognitive rest during symptom-provoking activities. Migraine/Headache: Education, relaxation training/mindfulness based therapy. Ocular-Exercises for ocular symptoms, near point convergence, may include Brock string, pencil push-ups, fixation, saccade tracking, pursuits. Sleep-Sleep regulation/hygiene. Mindfulness-based training, morning physical activity, CBT.Vestibular-Exercises for dizziness, visual motion sensitivity, gait, imbalance that may include gaze stability, visual habituation, static and dynamic balance/gait.

The CP Screen is a 29 item self-report, clinical profiles based symptom inventory that measures five concussion clinical profiles: 1) anxiety/mood, 2)cognitive/fatigue, 3) migraine, 4) ocular, 5) vestibular; and two modifying factors sleep and cervical. Participants indicate on a scale of 0 (none) to 3 (severe) the level of symptom severity for each item. The CP screen yields an average factor and modifier scores, with higher scores indicative of worse symptom severity, score range is 0-87.

The VOMS assesses impairment via patient report symptom provocation following each of 5 test components (smooth pursuits, horizontal/vertical saccades, convergence, horizontal and vertical vestibular ocular reflex (VOR) and visual motor sensitivity (VMS). Patients verbally rate changes in headache, dizziness, nausea, and fogginess after each test, as well as report their baseline symptoms. Symptoms in each area are rated on scale 0 (none) to 10 (severe). Scores on any VOMS item of 2+ reflects a positive screening cut-off for vestibular and/or ocular motor impairment.

Walking balance test, distance of 3 meters (10 feet). Participants are timed. Participants are seated in a chair, instructed to get up, walk 3 meters (marked on floor or by cone), round the cone, return to the chair and sit back down. Participants will repeat this 3 times, and we will use the average time. < 10 second = normal, <20 seconds, good mobility, <30 second, problems/may require aid. Higher scores indicating more problems with mobility.

PGIC is a self-reported assessment of change. Participants rate their impression of how much better they feel on a 7 point likert scale. It is a 1 item survey, with higher scores representing no change and associated with feeling worse. (Responses 1=much improved, 2=minimally improved, 3=no change, 4=minimally worse, 5=much worse, 6=very much worse).

Subject rates on a scale from 0% to 100% how much they feel like they are back to normal (before injury)
