What are brain disorders?
Brain disorders include underlying genetic and medical conditions, brain injuries and illnesses that affect the brain and how it develops both before birth and throughout childhood development. The brain can also be affected by certain medical treatments and exposure to certain toxins.
Common brain disorders include:
- a brain injury from a trauma to the head, stroke, lack of oxygen or an infection
- neurological conditions such as spina bifida, hydrocephalus, cerebral palsy, epilepsy, neurofibromatosis, tuberous sclerosis or a brain tumour
- other medical conditions such as prematurity, diabetes, chronic (long-term) heart or breathing problems, certain genetic disorders
- negative effects of treatments for leukemia, a brain tumour or other childhood cancers
- exposure to alcohol, smoking or certain drugs before birth
- exposure to lead, street drugs or poisonous gases, such as carbon monoxide.
How are mental health conditions related to brain disorders?
The brain manages the most complex of human functions such as thinking, problem solving, emotions, consciousness and social behaviour.
A brain disorder can alter a child's typical development. This can contribute to certain mental health issues related to their learning or behaviour depending on their age and the type and severity of the brain disorder.
Generally, mental health issues can arise from one, or both, of the following:
- difficulties with thinking, communication, emotional control and social skills
- difficulties adjusting to the stress associated with living with a brain disorder.
Difficulties with cognitive abilities – how the brain thinks
Mental health issues can be directly related to the way the brain is affected by a condition or injury. The changes in brain structure and connections as a result of a brain disorder can cause a child to have difficulties thinking, controlling behaviour and dealing with emotions and stress. This is illustrated by the following examples.
- Attention deficit hyperactivity disorder (ADHD) is one of the most common diagnoses following an illness or injury that affects the brain.
- Learning and intellectual disabilities are also frequent in children who have a brain disorder.
- Symptoms of depression and anxiety are also common outcomes. Sometimes these relate to the pattern of the brain injury, which may lead a child or teen to get stuck on persistent negative thoughts.
- Children with different types of brain injury may also struggle socially because of their difficulties communicating and knowing how to act with other kids.
Difficulties adjusting to and coping with a brain disorder
Adjusting to or coping with the effects of to a childhood brain injury or a related condition can be stressful and can increase mental health issues for children and their families. Common experiences may include:
- child frustration and sadness about their perceived differences at school or with peers (which may become more apparent in their teen years)
- child and parent stress about frequent doctor and hospital visits
- parental worry about a child’s current and future education and independence
- changes in parent-child relationships related to increased parental monitoring, attention or worry. This can become especially challenging when a teen wants more independence but needs parental monitoring and reminders for their health.
