Quick Answer
Most concussions resolve within 2-4 weeks in adults. Persistent symptoms beyond 4 weeks warrant specialist evaluation for post-concussion syndrome.

A concussion is a mild traumatic brain injury caused by a blow or jolt to the head. While most people recover fully, understanding the typical timeline and knowing when to seek further evaluation is important.
**Typical recovery phases.** In the first 24-48 hours, rest is essential —— both physical and cognitive. Avoid screens, reading, and mental exertion. Symptoms such as headache, dizziness, confusion, and fatigue are common. From day 3 to week 1, gradual reintroduction of light activity is appropriate if symptoms are improving. By weeks 2-4, most adults return to normal activities, though some symptoms may linger.
Dr. Jitendra Prasad Yadav — consultant neurologist & headache specialist at Kathmandu Neurology Clinic & Cognitive Center provides evidence-based evaluation for migraine.
**Children vs adults.** Children and adolescents often take longer to recover than adults. School-age children may need modified school schedules, reduced screen time, and avoidance of sports for longer periods. Each child's recovery should be guided individually.
**Gradual return to activity.** The current consensus supports a stepwise return to activity. Begin with light aerobic exercise (walking), then progress to sport-specific exercises, non-contact training, full-contact practice (with medical clearance), and finally return to competition. Each step should take at least 24 hours. If symptoms return, drop back to the previous step.
**Red flags requiring urgent evaluation.** Seek immediate medical attention for: worsening or persistent vomiting, seizures, worsening headache that does not improve, increasing confusion or agitation, weakness or numbness in limbs, slurred speech, unequal pupils, or loss of consciousness. These may indicate a more serious brain injury.
**Post-concussion syndrome.** When symptoms persist beyond 4 weeks in adults or 4 weeks in children, the condition is termed post-concussion syndrome. Persistent headache, dizziness, difficulty concentrating, and sleep disturbance are common. Management involves identifying and treating contributing factors such as cervical spine dysfunction, vestibular dysfunction, anxiety, and sleep disorders.
**When to see a specialist.** If recovery is not progressing as expected, or if symptoms are significantly interfering with daily life, a neurologist can evaluate for post-concussion syndrome and related conditions. This article is educational and does not replace individual medical advice.
