Concussion is a type of head injury that results in temporary loss of various functions (physical, cognitive, emotional) of the brain. It is primarily caused by a sudden powerful blow or jolt on the head. The cerebral fluid in the brain protects it from bumps and jolts. A severe blow sustained by the head can cause the brain to bump so hard on the skull that it ruptures blood vessels and tears the nerves. This leads to blood accumulation. Concussion may or may not result in loss of consciousness.

The number of people suffering from brain injuries is quite high. In the year 2008, more than three hundred thousand head injuries were reported that required emergency medical assistance. Statistics reveal that the numbers of males who suffer such brain injuries are much more than females. In addition, males between 15 and 24 years are at the highest risk of suffering from the brain injury. Also, people who have suffered a brain injury once are found to be much more prone to subsequent concussions. (See Reference 1)

The reason for the traumatic brain injuries may be as follows.

• One of the primary reasons for concussions is injuries that occur while riding on horsebacks or cycling. (See Reference 1)
• Assaults (attacks) are another unfortunate case that can be lead to such brain injuries. (See Reference 1)
• When a speeding vehicle suddenly loses speed or stops, it causes the brain to knock hard against the cranium leading to concussion. (See Reference 1)
• Injuries that occur while snowboarding, skiing, rugby, hockey, football, martial arts and other such types of sports can lead to concussions. One has to be careful while playing in playgrounds that do not have a soft surface. (See Reference 1)
• Trips or falls from staircases or from a height can result in a severe blow or jolt and result in concussion. (See Reference 1)

The common symptoms of concussions are:

• Fainting
• Fatigue
• Headache
• Dizziness
• Restlessness and Irritability
• Difficulty in focusing or concentrating
• Difficulty in decision making
• Lack of judgment
• Problems with speech
• Amnesia
• Vomiting
• Nausea
• Ringing sound in the ears
• Insomnia
• Depression
• Sensitivity to light and sounds

While some of these symptoms may occur immediately, others may be predominant after a few hours or even days.

If a patient experiences prolonged headache, dizziness, vomiting or nausea, continual dilation of pupils, loss of taste and smell senses, memory loss or absent-mindedness or ringing sound in the ears for few days, then the injury may be much more serious and may require immediate medical assistance.
