What Are The Top Brain Injury Causes and Symptoms


A traumatic brain injury, or TBI, is a head injury that results from a violent jolt/blow to the body or head, but it can also happen from an object going through the brain tissue, such as a shattered skull piece or a bullet.

The three common types of brain injuries range from mild or moderate to severe TBI, with serious ones often causing permanent brain damage and the others mild traumatic brain injury having some brain damage that goes away with time.

Typically, milder brain injuries temporarily affect the person’s brain cells, but some of the more serious moderate or severe TBI injuries might result in the person bruising, having torn tissues, bleeding, or incurring various other physical damage to the brain.

Sometimes called non-traumatic, and acquired head injury might not be as traumatic as some of the others.

What Are the Causes of a Traumatic Brain Injury?

A traumatic brain injury often gets caused by blows to the head or body, but the degree of damage depends on various factors, such as if it’s an acquired brain injury with no issues or severe brain damage occurs.

Common causes for this type of injury include:

  • FallsFalls from the ladder or bed, in the bath, downstairs, and others are highly common for a traumatic brain injury, primarily in older adults at the age of 65 or higher. Sports injuries may also occur.
  • Motor vehicle accidentsCollisions involving bicycles, motorcycles, pedestrians, and cars can cause injury to the brain or cause a spinal cord injury. (questions over sidewalk riding, making Los Angeles a dangerous place for pedestrians, etc.)
  • Violence – Child abuse, domestic violence, gunshot wounds, and other assault options can cause brain damage. The shaken baby syndrome is a severe head injury that happens in infants and is a type of traumatic brain injury caused by violent shaking.
  • Explosive Blasts – The pressure from an underground explosive blast igniting a car vault, for example, can cause severe injuries like a skull fracture and brain injury, and reduction of brain function.

What Complications Might Arise from a Brain Injury?

Complications from a head injury include:

  • Symptoms lasting for a longer period of time
  • Requirement of more CT scans to determine skull fractures
  • Neurological disorders and stroke
  • Difficulty writing, speaking, and understanding speech
  • Blood vessel damage
  • Diffuse axonal injury

People are at a high risk of brain damage if they’re younger than 4, play sports, or are male, but the risk also goes up for elderly adults. Seek medical advice from a doctor if you believe that you may have an injury to the head. If you don’t, a further injury may occur, and normal brain function may not return. Even a mild brain injury requires treatment.
