We are conducting a study that is looking at prolonged concussion symptoms and their impact on memory and emotions. We want to know what kind of lasting symptoms people have and if the number of concussions or other health issues, such as depression, makes people have more difficulties with memory and emotions. This is a clinical research study and it is not intended to provide treatment for a concussion.

We are recruiting both participants for the concussion group and the control group.

Concussion Group Inclusion Criteria:Control Group Inclusion Criteria:
– Have prolonged symptoms from a sport-related concussion that happened at least 1 month prior
– Be aged 18-60 years old

Potential risk/discomfort. Some of the questions in this study do ask about stressful experiences, negative thinking, sadness, and depression. For some individuals, answering these questions may produce some discomfort.

There is the chance of participants having aggravated symptoms from participating in the study. These may be from moderate to severe symptoms. The computer work may cause discomfort and this worsening of symptoms. These aggravated symptoms may include headache, dizziness, nausea, and/or discomfort. After the study, if you experience worsening of your symptoms, you are asked to return home and rest both physically and mentally. Should you find that your symptoms are not decreasing, you should seek medical attention from either your physician or the study’s physician.  As this study is completely voluntary, you may choose not to participate, and you can skip questions you do not wish to answer. Please note, that the present study is conducted under the supervision of a physician, Dr. Taryn Taylor. You can make a virtual appointment to see her at Carleton Sport Medicine Clinic if you have any questions or concerns (613-520-3510).
