Symptoms can change after a concussion; danger signs need emergency care.

A concussion is a type of traumatic brain injury. Symptoms may affect the body, thinking, emotions, or sleep and may not appear immediately.

Track what changed, when it began, and how it affects daily life.

CDC lists possible symptoms such as headache, dizziness or balance problems, nausea, sensitivity to light or noise, fatigue, concentration or memory difficulty, mood changes, and sleep changes.

Persistent symptoms deserve medical assessment because an online label cannot determine the cause, severity, or appropriate care plan.

Know the danger signs after a head injury.

Call 911 or go to an emergency department for danger signs such as worsening headache, repeated vomiting, seizure, increasing confusion, slurred speech, weakness or numbness, unequal pupils or double vision, or inability to wake or stay awake.

This emergency guidance directs readers to emergency services, not to Gates Brain Health.
