By on April 3rd, 2022.Health

What Is a Concussion?

The most common and least serious type of traumatic brain injury is called a concussion. The word comes from the Latin concutere, which means “to shake violently.” A concussion is most often caused by a sudden direct blow or bump to the head.

According to the CDC, between 2001 and 2009, an estimated 173,285 people under age 19 were treated in hospital emergency rooms for concussions related to sports and recreation activities. Other causes include car and bicycle accidents, work-related injuries, falls, and fighting.

Concussion Causes and Risk Factors.

The brain is made of soft tissue. It’s cushioned by spinal fluid and encased in the protective shell of the skull. When you have a blow or bump to your head, the impact can jolt your brain. Sometimes, it literally causes it to move around in your head. Traumatic brain injuries can cause bruising, damage to the blood vessels, and injury to the nerves.

The result is your brain doesn’t function as it should. If you’ve had a concussion, vision may be disturbed, you may lose equilibrium, or you may fall unconscious. In short, the brain is confused.

Some things increase your risk for a concussion, including:

Falls, particularly in children and older adults, Playing a contact sport, Lack of proper safety gear or supervision for contact sports, Car, motorcycle, bicycle, and other accidents that cause a blow to the head, Being hit, struck with an object, or other physical abuse, Military service, An earlier concussion, Concussion can be tricky to diagnose. Though you may have a visible cut or bruise on your head, you can’t see a concussion. Signs may not appear for days or weeks after the injury. Some symptoms last for just seconds; others may linger.

Concussions are fairly common. Some estimates say a mild brain trauma is sustained every 21 seconds in the U.S. But it’s important to recognize the signs of a concussion so you can take the proper steps to treat the injury.

There are some common physical, mental, and emotional symptoms a person may display following a concussion.

Signs of traumatic brain injury include:

  • Confusion or feeling dazed
  • Clumsiness
  • Slurred speech
  • Nausea or vomiting
  • Headache
  • Balance problems or dizziness
  • Blurred vision
  • Sensitivity to light
  • Sensitivity to noise
  • Sluggishness
  • Ringing in earsIrritability or other behavior or personality changes
  • Difficulty concentration
  • Loss of memory
  • Fatigue or sleepiness
  • Loss of consciousness
  • Forgetfulness such as repeating yourself
  • Slowed response to questions
  • Problem with sleep
  • Depression
  • Problems with taste or smell

Concussions in Children

Because their heads are disproportionately large compared to the rest of their body, concussions often occur in young children. As kids enter adolescence, they experience the rapid height and weight gain.

Both are factors that make them more prone to accidents than adults.If a child has a concussion, an adult should monitor them for the first 24 hours. on’t give medications, including aspirin, which may cause bleeding, to a child without talking to a doctor first.

It’s important to watch for behavioural changes. Young children, especially, may not be able to fully communicate what they’re feeling, so it is critical to watch them closely.Symptoms of concussions in children include:

  • Headache
  • Dizziness
  • Problems with balance
  • Upset stomach or vomiting
  • Fatigue
  • Sensitivity to light or noise
  • Mental fogginess or slowed thinking
  • Problems with memory, concentration, or focus
  • Feeling more irritable, sad, nervous, or emotional than usual
  • Problems with sleep

Types Of Concussions

Doctors rank, or grade, the severity of concussions based on things like loss of consciousness, amnesia, and loss of equilibrium.

There are three grades:

1: Mild, with symptoms that last less than 15 minutes and involve no loss of consciousness

2:Moderate, with symptoms that last longer than 15 minutes and involve no loss of consciousness

3: Severe, in which the person loses consciousness, sometimes for just a few seconds Concussion Diagnosis, Most people with concussions fully recover with appropriate treatment.

But because a concussion can be serious, safeguarding yourself is important. Here are a few steps to take:Seek medical attention. A health care professional can decide how serious the concussion is and whether you require treatment.If you have a grade 1 or grade 2 concussion, wait until symptoms are gone before returning to normal activities. That could take several minutes, hours, days, or even a week.If a person has lost consciousness, that’s a grade 3 concussion that needs a doctor’s immediate evaluation and care.

They’ll ask how the head injury happened and discuss the symptoms. The doctor may also ask you simple questions such as “Where do you live?” “What is your name?,” or “Who is the president?” The doctor asks these questions to evaluate memory and concentration skills.The doctor may test coordination and reflexes, which are both functions of the central nervous system. The doctor may also order a CT scan or an MRI to rule out bleeding or another serious brain injury.

Concussion Treatment and Home

If you don’t need hospitalization, the doctor will give you instructions to follow. Experts recommend follow-up medical attention within 24 to 72 hours if symptoms worsen. To recover at home, you should:Take a break. If your concussion was sustained during athletic activity, stop play and sit it out. Your brain needs time to properly heal, so rest is key. Definitely do not resume play the same day. Athletes and children should be closely monitored by coaches upon resuming play. If your resume plays too soon, you risk a greater chance of having a second concussion, which can compound the damage.

The American Academy of Neurology has issued guidelines about resuming activities after a concussion.Guard against repeat concussions. Repeat concussions cause cumulative effects on the brain. Successive concussions can have devastating consequences, including brain swelling, permanent brain damage, long-term disabilities, or even death.

Don’t return to normal activities if you still have symptoms. Get a doctor’s clearance so you can return to work or play with confidence.Treat pain with aspirin-free medications. Your doctor will prescribe a medication to relieve pain or recommend an over-the-counter option.

Concussion Prevention

A concussion is unexpected, so it is tough to prevent. But there are several commonsense precautions you can take to lessen the possibility of traumatic brain injury.Wear protective equipment. Participation in high contact, high-risk sports such as football, hockey, boxing, and rugby can increase the likelihood of a concussion. Skateboarding, snowboarding, horseback riding, and rollerblading are also a threat to your brain’s health.

Wearing headgear, padding, and mouth and eye guards can help safeguard against traumatic head injuries. Wearing a bike helmet can lower the risk of traumatic head injury by 85%. There is also a new C-shaped collar-like device called Q-Collar which can be worn by athletes.

It applies compressive force to the neck and increases blood volume to help reduce movement of the brain, which may occur because of hits to the head. Make sure that any equipment fits you correctly and is well-maintained.Drive and ride smart. Always wear a seatbelt, obey posted speed limits, and don’t use drugs or alcohol, because they can impair reaction time.

Don’t fight. Concussions are often sustained during an assault, and more men than women report traumatic head injuries.Reduce trip and fall hazards in your home. Clear clutter from floors and hallways and make sure your home is well-lighted.

Exercise regularly. It can give you stronger leg muscles and better balance, which can help stave off falls.Use home safety measures to protect your children. Install window guards and block stairways.
