mTBI and Concussions

Mild Traumatic Brain Injury (mTBI), commonly known as a concussion, occurs when a blow or jolt to the head or body disrupts normal brain function. Symptoms can include headaches, dizziness, nausea, difficulty concentrating, or mood changes. These may appear immediately or develop over time.

If you suspect a concussion: 

• Stop all physical activity or exercise.
• Seek evaluation promptly.
• Limit screen time and intense mental tasks if symptoms persist.

Student-athletes have specific support through Sports Medicine, and should contact thier trainer if an mTBI is suspected. All students can receive care at the Student Health Center at Dick's House, which offers same-day appointments and a 24/7 nurse advice phone line at 603-646-9440 for after-hours questions and concerns.

For emergencies, call 911 or visit the nearest emergency department.

Preventing concussions (mTBI) starts with being mindful of situations that increase the risk of head trauma. Consider the following:

• Wear a properly fitted helmet for biking, skating, and other activities. Research shows that helmets reduce the risk of head, brain, and severe brain injury by 63–88% among bicyclists of all ages, provide similar protection in crashes involving motor vehicles (69%) and those from other causes (68%), and reduce upper and mid facial injuries by 65%. Helmet research is an ongoing science, and some of the best work is being done right here at Dartmouth

• Follow established safety rules and guidelines during athletic events.

• Use seat belts consistently and avoid distractions while driving.

• Maintain a safe environment by removing trip or collision hazards.

• Use caution during activities with a higher fall risk, such as rock climbing or skateboarding.

Managing a concussion (mTBI) involves rest, gradual reintroduction of activities, and monitoring symptom changes. This can be very challenging to do in balance with the demands you may experience on campus, and for this reason we strongly recommend talking to a clinician at the Student Health Center at Dick's House to help come up with a plan that includes:

• Rest both brain and body, especially during the first few days.
• Limit or pause strenuous activities and minimize screen time.
• Gradually return to daily tasks, monitoring how you feel.
• Checking in with the Health Service team for personalized care and follow-up.
• If symptoms worsen or new ones appear, seek immediate medical evaluation.
