Post Concussion Syndrome


Post-concussion syndrome (PCS)

is a group of symptoms that affect your nerves, thinking, and behavior. PCS develops shortly after a concussion and can last for weeks to months.

Common signs and symptoms of PCS:

  • Headaches or problems with your vision
  • Dizziness or poor balance
  • Forgetfulness or problems concentrating
  • Problems with sleep
  • Changes in your personality
  • Seizures
  • Depression or anxiety

Call 911 or have someone else call for any of the following:

  • You have a seizure.
  • You have trouble breathing.
  • You are not responding or you cannot be woken.

Seek care immediately if:

  • You have a sudden headache that seems different or much worse than your usual headaches.
  • You cannot stop vomiting.
  • You have sudden changes in your vision.

Contact your healthcare provider if:

  • You have nausea or are vomiting.
  • You have trouble concentrating.
  • You have difficulty speaking or thinking.
  • Your symptoms get worse.
  • You have questions or concerns about your condition or care.


will focus on your symptoms. You may need any of the following:

  • Acetaminophen decreases pain. It is available without a doctor's order. Ask how much to take and how often to take it. Follow directions. Acetaminophen can cause liver damage if not taken correctly.
  • NSAIDs, such as ibuprofen, help decrease swelling, pain, and fever. This medicine is available without a doctor's order. Follow directions. NSAIDs can cause stomach bleeding or kidney problems if not taken correctly. If you take blood thinner medicine, always ask if NSAIDs are safe for you.
  • Antidepressants may be given for depression or sleep problems.
  • Migraine medicines may be given for migraine headaches.

Risks of PCS:

PCS may decrease your ability to function at home, school, or work. You may develop persistent post-concussion syndrome. You may develop second-impact syndrome if you have another concussion before you have recovered from the first. Second-impact syndrome can be life-threatening.

Prevent PCS:

  • Make your home safe. Home safety measures can help prevent head injuries that could lead to a concussion. Install handrails for every staircase. Put soft bumpers on furniture edges and corners. Secure furniture, such as dressers and book cases so they do not fall over.
  • Always wear a seatbelt in the car. This helps decrease your risk for a head injury if you are in a car accident.
  • Wear protective sports equipment that fits properly. Helmets help decrease your risk for a serious brain injury. Talk to your healthcare provider about other ways that you can decrease your risk for a concussion if you play sports.

Manage your symptoms:

  • Rest from physical and mental activities as directed. Mental activities need you to think, concentrate, and pay attention. Rest will help you recover from your concussion. Ask your healthcare provider when you can return to school and other daily activities.
  • Go to therapy as directed. A cognitive behavioral therapist teaches you skills to help with any thinking and behavior problems you may have. An occupational therapist teaches your skills to help with daily activities.
  • Do not participate in sports or physical activities until your healthcare provider says it is okay. These activities could make your symptoms worse or lead to another concussion. Your healthcare provider will tell you when it is okay to return to sports or physical activities.
