A concussion occurs when the brain is jostled so severely that it impacts the inside of the skull. If a person hits their head or their body is hit hard enough to cause their head to jerk violently, the cushion of water that surrounds and protects the brain cannot absorb the impact. The brain is a sensitive organ, so any contact between it and the skull can cause damage. Concussions are considered severe brain trauma, and can be dangerous if left untreated. Any significant blow to the head can lead to a concussion.Symptoms may not be readily apparent immediately following the injury, so it is important to watch for symptoms to develop over time whenever someone suffers any sort of sharp blow to the head. Symptoms can last as little as a few hours or as long as a few weeks depending on the severity of the brain damage. Repeated damage can lead to more permanent brain damage, but most concussions will fully heal with proper care and treatment. The most effective treatment is total rest, which includes not performing any physical or stressful mental activity until the brain has time to heal. Seek treatment from a professional if you experience any of the following symptoms for more than one day:
