Concussion Treatment in Older Adults

August 5, 2026 updated by: Anthony P. Kontos, Ph.D., University of Pittsburgh

Randomized Controlled Trial of Targeted Treatment in Older Adults Following Concussion

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.

Detailed Description

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Concussion Clinical Profiles Screening (CP Screen)
Time Frame: Visit 1 (Baseline)
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.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Vestibular/Ocular Motor Screening (VOMS)
Time Frame: Visit 1 (Baseline)
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).

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.
