Why Do Traumatic Brain Injuries Occur? 

A brain injury is determined by the nature and the force of the impact to the brain. Traumatic brain injuries most often happen when the head suddenly hits an object or the object pierces the head and skull affecting brain tissue. The Mayo Clinic reports that the most common causes that can traumatically injure the brain are:

Common Brain Injury Symptoms

The Mayo Clinic classifies symptoms of brain injuries into three categories:

  • Physical Symptoms
  • Sensory Symptoms
  • Cognitive Symptoms

The Clinic further reports that there can be numerous indications that someone has sustained a traumatic brain injury. Those indications, or symptoms, can be divided into short-term and long-term symptoms.

Short-Term Brain Injury Symptoms

Short-term symptoms, unlike long-term symptoms, are generally only physical symptoms rather than sensory or cognitive symptoms. A non-exhaustive list of common short-term symptoms of brain injuries includes:

  • Blood Infections
  • Blood Vessel Damage
  • Headaches
  • Nausea
  • Fuzzy or Blurry Vision
  • Double Vision
  • Vomiting
  • Dizziness
  • Light Sensitivity
  • Vertigo

Long-Term Brain Injury Symptoms

While short-term symptoms are mainly contained to immediate or near-immediate physical onsets, long-term symptoms may not as appear immediate or seem as harmless. Long-term symptoms can emerge as physical, sensory, and or cognitive changes in the victim that suffered the brain injury.

Cognitive symptoms of traumatic brain injuries include trouble with:

  • Memorizing new information

Common Symptoms of Brain Injuries in Different Age Groups

The formerly listed symptoms can be present in any individual of any age. Nevertheless, there are some symptoms of brain injuries that emerge more frequently in adults than in children and vice versa.

Symptoms in Adults

  • Persistent Headaches
  • Decreased Coordination
  • Slowed or Slurred Speech
  • Insomnia
  • Dilated Pupil or Pupils
  • Unusual agitation or restlessness

Effects of Brain Injuries

Apart from injuries to the body, traumatic brain injuries can have significant negative effects on social and work life. An article published in the The National Library of Medicine showed that less than ⅓ of participants in a study worked full-time after a traumatic brain injury and all the participants generally had financial struggles. A similar study showed that only 40% of people who suffered a traumatic brain injury were still able to enjoy the same leisure activities they did before the injury.
