Prolonged concussion is defined as having concussion symptoms for over four weeks following the first accident in youth and for weeks or months in adults. [7] A diagnosis may be made when symptoms resulting from concussion last for more than three months after the injury.
[3] [5] All age groups can be affected from sleep disorders after TBI, including children [1] and adolescents. [6] There are several risk factors that are associated with occurring sleep disorders, such as lower years of education, severity of head injury and occurrence of residuals symptoms, for example headache or dizziness. [1]
Traumatic brain injury (TBI, physical trauma to the brain) can cause a variety of complications, health effects that are not TBI themselves but that result from it. The risk of complications increases with the severity of the trauma; [1] however even mild traumatic brain injury can result in disabilities that interfere with social interactions, employment, and everyday living.

A concussion can lead to symptoms such as dizziness, headaches and memory problems. But concussions are treatable. The usual treatment is rest — for the body and the brain.
A concussion, also known as a mild traumatic brain injury (mTBI), is a head injury that temporarily affects brain functioning. [8] Symptoms may include headache, dizziness, difficulty with thinking and concentration, sleep disturbances, mood changes, a brief period of memory loss, brief loss of consciousness; problems with balance; nausea; blurred vision; and mood changes.
Second-impact syndrome (SIS) occurs when the brain swells rapidly, and catastrophically, after a person has a second concussion before symptoms from an earlier one have subsided. This second blow may occur minutes, days, or weeks after an initial concussion, [1] and even the mildest grade of concussion can lead to second impact syndrome. [2]
The test, which can be self-administered or given by an interviewer, asks patients to rate the severity of 16 different symptoms commonly found after a mild traumatic brain injury (MTBI). [6] Patients are asked to rate how severe each of the 16 symptoms has been over the past 24 hours.
Acute concussion symptoms (those that occur shortly after an injury) should not be confused with CTE. Differentiating between prolonged post-concussion syndrome (PCS, where symptoms begin shortly after a concussion and last for weeks, months, and sometimes even years) and CTE symptoms can be difficult.
