How A Traumatic Brain Injury Damages Essential Neurons

Brain injury damages neurons

Understand how a traumatic brain injury damages neurons disrupting the brain’s networks


A TBI can be so debilitating because a brain injury damages neurons that serve as the information highways in the brain. The brain is made up of a special type of cell called a neuron. Neurons form highly complex networks. These  networks create billons of electrochemical connections as one neuron pulses and transmits information to the next. The information comes in the form of various chemical neurotransmitters.

Neurons have 4 major structural components:

  • A nucleus within a cell body
  • Dendrites
  • An axon insulated in a myelin sheath
  • Axon terminals

The branching arms of the dendrites receive stimulation from other neurons. The chemical impulse is transmitted down the axon to its terminals. The axon terminals hold neurotransmitters that are then released to stimulate the dendrites of the next neuron.

There are approximately 100 billion neurons in the brain. The extensive networks of neurons in the brain are what allow the brain to control breathing, movement, thought, and personality. Humans are born with essentially all of the neurons they will ever have. That is why traumatic brain injury can permanently change the behavior of the injured person.

Brain Injury Damage to Neurons Can Irreversibly Change a Person

When a person suffers a traumatic brain injury, large numbers of neurons in the brain can be damaged or destroyed. Such destruction can stop the functioning of entire networks of neurons. Some neural circuits may eventually reactivate if damaged cells resume some functioning or alternative networks are formed to compensate for the damage. In some cases, however, the damage is too extensive and a person’s behavior, memory, or personality can be permanently changed.
