What symptoms or difficulties can my child with a brain injury experience?

Symptoms you may notice include:

What symptoms or difficulties can my child with a more serious brain injury experience?
Children 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)
