Some experts believe post-concussion symptoms are caused by structural damage to the brain or disruption of neurotransmitter systems, resulting from the impact that caused the concussion. [medical citation needed] Others believe that post-concussion symptoms are related to common psychological factors. Most common symptoms like headache ...
Concussion should be suspected if a person indirectly or directly hits their head and experiences any of the symptoms of concussion. [10] Symptoms of a concussion may be delayed by 1–2 days after the accident. It is not unusual for symptoms to last 2 weeks in adults and 4 weeks in children.
A pediatric concussion can lead to an immediate or delayed onset of symptoms. [12] Immediate onset of symptoms includes physical impacts, such as dizziness, headache, anterograde or retrograde amnesia, loss of consciousness, vomiting and more. [1] Delayed onset of symptoms may occur a few hours or days after the injury.
But the recovery time can vary. Up to about 1/3 of people experience persisting symptoms after concussion (PHAC) or persistent post concussion symptoms (PPAC), defined as symptoms that last more than 4 weeks. [5] [6] [7] After an injury, concussion symptoms can begin immediately or be and delayed by 1-2 days at most. [8]
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. In some cases ...
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]
A concussion is a form of a mild traumatic brain injury (TBI). This injury is a result due to a blow to the head that could make the person's physical, cognitive, and emotional behaviors irregular. Symptoms may include clumsiness, fatigue, confusion, nausea, blurry vision, headaches, and others. [7] Mild concussions are associated with sequelae ...
Since axonal damage in DAI is largely a result of secondary biochemical cascades, it has a delayed onset, so a person with DAI who initially appears well may deteriorate later. Thus injury is frequently more severe than is realized, and medical professionals should suspect DAI in any patients whose CT scans appear normal but who have symptoms ...
