Signs and Symptoms
The abbreviation PCS may also be used to mean post-concussion symptoms. Symptoms can appear immediately, or weeks to months after the initial injury. Their severity lessens progressively over time. The nature of the symptoms tends to change over time: they are most commonly of a physical nature following the injury, but tend to become predominantly psychological later. Signs and symptoms such as noise sensitivity, problems with concentration and memory, irritability, depression, anxiety, fatigue, and poor judgment may be called 'late symptoms' because they generally do not occur immediately after the injury, but rather days or weeks after. Nausea and drowsiness commonly occur two to four weeks after concussion and can be long lasting. Also, headache and dizziness occur immediately after the injury and can be long lasting.
