How Long Does a Concussion Last?

Concussions are one of the most common forms of traumatic brain injury (TBI) and can happen to anyone experiencing a blow, jolt, or impact to the head. While often called “mild,” a concussion is still a serious brain injury that can temporarily affect memory, balance, and cognitive function. Ignoring or delaying care for a concussion can worsen symptoms and increase the risk of long-term complications, especially for people with a history of head trauma. Seeking prompt medical attention after any trauma injury is crucial, and consulting experienced professionals ensures proper evaluation, treatment, and guidance for safe recovery.

What Is a Concussion?

A concussion is a type of mild traumatic brain injury (mTBI) that happens when the brain is shaken inside the skull due to a bump, blow, or sudden jolt. This movement disrupts brain cell communication, leading to temporary problems with thinking, balance, memory, or coordination.

  • Concussions don’t usually show up on CT scans or MRIs, but the symptoms are real and need proper care.
  • Even though called “mild,” concussions can have serious consequences if ignored or repeated.

How Long Does a Concussion Last on Average?

  • Adults: Most recover in 7–14 days.
  • Children & Teens: Often take 2–4 weeks or longer.
  • Some Cases: Symptoms may persist beyond a month (post-concussion syndrome).

The exact duration depends on:

  • Age and overall health
  • Severity of the initial injury
  • History of past concussions
  • How well rest and recovery guidelines are followed

Recovery Timeline After a Concussion

Every concussion recovery is unique, and symptoms can fluctuate from day to day. Understanding the typical timeline helps you plan rest, activity, and medical follow-ups to ensure safe healing after head trauma.

First 24–48 Hours

  • Expect headaches, dizziness, nausea, sensitivity to light or sound.
  • Doctors recommend “relative rest” (avoid intense physical or mental activity but don’t lie in bed all day).
  • Hydration, quiet activities, and short naps are encouraged.

Days 3–7

  • Symptoms often improve, but mild fogginess or fatigue may remain.
  • Light physical activity like walking is okay if it doesn’t worsen symptoms.
  • Limit screen time, loud environments, and heavy work.

Weeks 2–3

  • Many people start feeling normal again.
  • Students may return to school with light accommodations (reduced screen use, shorter class hours).
  • Adults may return to work gradually with breaks.

1 Month and Beyond

  • If symptoms linger, this may be post-concussion syndrome (PCS).
  • Persistent dizziness, vision issues, or headaches require specialized care like vestibular or vision therapy.

How Long Do Concussion Symptoms Last?

Concussion symptoms vary widely depending on the severity of the head trauma and individual factors like age and medical history. Tracking these symptoms closely ensures timely care and reduces the risk of prolonged brain injury.

Headaches

  • Usually resolve within 1–2 weeks.
  • Migraines triggered by concussions may last longer.

Dizziness & Balance Issues

  • Often improve in 7–14 days, but some people need vestibular therapy if symptoms persist.

Cognitive Problems (Memory, Focus, “Brain Fog”)

  • Most resolve within 1–3 weeks.
  • Can last longer in teens, older adults, or those with ADHD/anxiety.

Sleep Disturbances

  • Trouble falling asleep or oversleeping is common.
  • Typically improves in 2–3 weeks with good sleep hygiene.

Sensory Issues (Light/Noise Sensitivity, Vision Strain)

  • Common in first 2 weeks.
  • May persist and benefit from vision therapy or blue-light filters.

Factors That Can Delay Recovery

  1. Age: Children and older adults heal more slowly.
  2. History of Previous Concussions: Recovery can take longer if multiple concussions have occurred.
  3. Pre-existing Health Conditions: Migraines, anxiety, depression, or ADHD may prolong symptoms.
  4. Severe Initial Symptoms: Strong dizziness, memory loss, or headache often predict longer recovery.
  5. Poor Rest After Injury: Returning to activity too soon delays healing and risks re-injury.

Concussions in Children and Teens

  • Brains are still developing, so recovery is slower.
  • Typical duration: 2–4 weeks or more.
  • Schools should support recovery with:
    • Reduced workload
    • Extra test time
    • Breaks in quiet spaces
    • Limited screen exposure
  • No sports until cleared by a doctor.

Warning Signs:

Call 911 or visit an emergency center if you notice:

  • Severe or worsening headache
  • Repeated vomiting
  • Seizures or fainting
  • Trouble speaking or walking
  • Unequal pupil sizes
  • Clear fluid or blood from ears/nose
  • Extreme confusion or unusual behavior
  • Difficulty waking up

Diagnosing a Concussion

  • Neurological Exam: Balance, memory, reflexes, coordination.
  • Imaging (CT/MRI): Not always needed, but used to rule out bleeding or fractures.
  • Symptom Checklist: Helps doctors track recovery progress.

Best Treatment for Concussion Recovery

First 48 Hours

  • Rest your brain and body.
  • Avoid sports, heavy lifting, or long screen time.
  • Use acetaminophen (Tylenol) for headaches (avoid ibuprofen/aspirin early due to bleeding risk).

After 48 Hours

  • Gradually reintroduce physical and mental activity.
  • Gentle walking, light school/work tasks.
  • Stop if symptoms worsen.

Ongoing Recovery

  • Sleep hygiene: Regular sleep schedule, avoid caffeine late in the day.
  • Hydration & Nutrition: Proper diet speeds healing.
  • Therapies: Vestibular therapy, vision therapy, or physical therapy if symptoms don’t improve.

Return-to-School or Work

  • Start part-time if symptoms remain.
  • Use accommodations: frequent breaks, reduced screen time, quiet environment.
  • Gradually increase workload as tolerated.

Return-to-Sports Protocol

Athletes should only return to play after being cleared by a doctor. Stepwise approach:

  1. Light activity (walking, light cycling)
  2. Sport-specific drills (no contact)
  3. Non-contact training with more intensity
  4. Full practice with contact
  5. Competitive play

If symptoms reappear, step back and rest for 24 hours before trying again.

Post-Concussion Syndrome (PCS)

  • If symptoms last more than 4 weeks, PCS may be diagnosed.
  • Common in people with repeated concussions or pre-existing health issues.
  • Treatment may include:
    • Vestibular therapy for balance
    • Vision therapy for eye strain
    • Medication for chronic headaches
    • Cognitive-behavioral therapy for anxiety/sleep issues
