How a Head Injury Affects the Brain

A head injury can be caused by a violent blow or jolt to the head, or by an object penetrating the brain tissue. The consequences of a head injury are unpredictable and impact everyone differently.

Brain injuries can be extremely serious, causing:

  • Long-term debilitation
  • Changes to the way a person communicates and behaves
  • Physical, cognitive and emotional effects

Anyone who has sustained a head injury requires specialist medical treatment and rehabilitation, as well as ongoing care and support. Find out how brain injuries are treated here.

In a survey, conducted by JMW’s personal injury team, we found that despite one-in-four people knowing somebody with a head or brain injury, there is a need for a better understanding of the condition. The majority of participants were unable to name all the symptoms experienced by somebody with a head injury. Read more about our survey findings here.

To help you understand the impact of a head injury on the brain, we have created these interactive images to show you what parts of the brain are responsible for certain actions and what can happen if that area of the brain is damaged.
