Participate in Research

Why participate in research?

Research is the key that unlocks our ability to prevent and treat the effects of brain trauma. Brain bank research has provided undeniable evidence of how repetitive brain trauma affects behavior, thinking and memory. Clinical research on human volunteers plays an equally critical role in accelerating progress and can provide crucial insights on potential treatments. You can scroll down this page to learn about actively recruiting research studies that you may be eligible for.

First, watch Dr. Robert Stern, director of clinical research at the Boston University CTE Center, explain why you should participate in research.

Project S.A.V.E

Location: Boston University or the University of California, San Francisco

Seeking: Men and women age 50 or older who played 5+ years of a contact sport, including American football, ice hockey, soccer, lacrosse, boxing, full contact martial arts, rugby, and wrestling. The study consists of a 1-2 day study visit at either Boston University or the University of California, San Francisco. Each visit will consist of an advanced MRI of the brain; neurological, cognitive, self-report mood and behavior exams; blood samples; and an optional lumbar puncture. Participants will return annually.

Goal: S.A.V.E. stands for Study of Axonal and Vascular Effects from repetitive head impacts. The major goal of this study is to determine how repeated head impacts from playing contact sports can lead to long-term thinking, memory, and mood problems. The results of this study could inform on strategies to treat and prevent symptoms associated with head impacts from contact sports.

Athlete Brain Health & Aging Study

Athlete Brain Health & Aging Study
Location: National
Seeking: Former NFL players, former Division I college football players, and former male college athletes who never played contact sports.
Goal: The purpose of this research study is to use research to improve health and support the well-being of men of all ages. Previous research on brain health has focused on biological factors, but we know that a person’s psychology, personal beliefs, social groups, and surroundings are also fundamental for brain wellness. These psychosocial factors vary for different groups, such as among Black, White, and Latino men, but more must be understood about how these factors affect brain health. The goal of this study is to discover the effects these important factors have on brain aging to support people like you, your friends, family, and community members.

Boston University COVID & Cognition Study

BU COVID & Cognition Study

Location: Nationwide 

  • At least 18 years of age
  • Fluent in English
  • Access to an Internet-connected smartphone (iOS or Android) or tablet device
  • No plan to undergo any major treatments or surgery during the next 6 months
  • No diagnosis of dementia, stroke, or major depressive disorder
  • No admission to the Intensive Care Unit (ICU) since 2018
  • No history of head injury or concussion

Background & Detail: 

Many COVID-19 patients experience neurological consequences, such as problems with memory, attention, and brain fog.  There is currently a lack of understanding of how COVID-19 impacts neurological functioning, cognition, and mood.  Gather more information on the neurocognitive impact of COVID-19 could help develop treatments that aim to produce better outcomes while better characterizing the effects of COVID-19 on the brain. 

This project will use mobile-based assessments, including smartphones and tablets, to characterize the neurocognitive effects of COVID-19 with higher precision and frequency than done with traditional neuropsychological testing.  We aim to determine whether the cognitive capacity, mood, and sleep patterns of individuals who have ever been infected with COVID-19 is distinguishable from individuals who have never been infected with COVID-19.  Having ever been infected with COVID-19 will distinguish the two groups recruited in the study (Group 1: Ever-COVID; Group 2: Never-COVID).  The date and reported severity of COVID-19 infection, as well as details related to changes in lifestyle will be recorded to help characterize their recovery trajectory.

The first smartphone application used in this project consists of 7 cognitive tasks and 2 questionnaires, and in total is expected to take around 15 minutes to complete.  The second smartphone application used in this project involve assessing cognition through voice and speech elicitation tasks, and is expected to take around 8 minutes to complete.  Participants will complete a practice session with the smartphone applications in the presence of a study staff during the remote study visit to ensure they are comfortable using the applications. 

Following the remote study visit, participants will be asked to complete one assessment per week on each application for the first 1.5 months (6 weeks) of the study, followed by an additional 6 assessments (at minimum) over the remaining 4.5 months in the study.  At the end of the study participation, participants will also be asked to complete a study survey to provide feedback on their experience in the study and use of the smartphone applications.  Participants will be eligible to receive gifts cards for completing assessments.  A $25 gift card will be mailed to participants following the completion of the first 6 assessments over the course of the first 1.5 months of the study, followed by another $25 gift card if they complete an additional 6 assessments (at minimum) over the remaining 4.5 months of the study.
