Brain Injury

Symptoms or difficulties following a brain injury

Your child may experience a variety of symptoms or difficulties following a brain injury - it depends on:

  • the type of injury - a brain injury may occur due to an accident, such as a fall (which is called a traumatic brain injury) or due to an illness that affects the brain
  • how serious the brain injury is

Symptoms or difficulties following a mild brain injury

Most tamariki (children) who have a mild traumatic brain injury (also called a concussion) get better within 2 to 3 weeks, although they can take a little longer.

Symptoms you may notice include:

  • headache
  • tiredness
  • changes in sleeping patterns
  • some dizziness
  • sensitivity to light, noise or busy environments
  • being more grumpy or irritable or getting upset easily
  • taking longer to process information or respond to questions
  • finding it harder to concentrate on schoolwork or other activities

You can also check the ACC guide on caring for your child after their head injury. This gives advice on:

  • how to care for your child after a mild brain injury/concussion
  • warning signs to watch for
  • when to seek medical help
  • when to return to school, sport and other activities

Your doctor or hospital staff can also give you advice. If your child has more symptoms or they are taking a while to improve, they may need to see a concussion service funded by the Accident Compensation Corporation (ACC).

Symptoms or difficulties of a more serious brain injury

Tamariki who have a more serious brain injury (whether through an accident or illness) can have longer-term symptoms. These can continue to affect them after they have left the hospital. Common long-term symptoms include tiredness (or fatigue) and changes in thinking, behaviour and emotions.

Tiredness (mental and physical)

  • needing more sleep at night and feeling sleepy in the daytime
  • running out of brain energy quickly while concentrating on schoolwork
  • getting tired more easily after physical activities

  • difficulty holding things in memory
  • difficulties with planning and organisation

Brain Injury - Difficulties With Concentration & Taking In Information

Behavioural and emotional symptoms

Your child may experience behavioural and emotional changes, such as:

  • getting upset or angry more easily
  • behaving more impulsively
  • being restless or overactive
