Neuropsychology studies the relationship between cognition and behaviour. The health professional assesses patients for cognitive or behavioural disorders. Specialising in attention deficit disorder with or without hyperactivity (ADD/ADHD), intellectual giftedness (IG), or autism spectrum disorder (ASD), they seek to understand how these disorders are related to neurological problems or neurodevelopmental differences, and to identify the best treatments to help patients function optimally in their daily lives.

Child psychiatry focuses on the assessment, diagnosis and treatment of mental disorders in children and adolescents. The health professional works with patients who may suffer from behavioural disorders, anxiety, depression, eating disorders, sleep disorders, developmental disorders, or autism spectrum disorders.

Psychotherapy, or talk therapy, is a way to help people with a broad variety of mental illnesses and emotional difficulties. Psychotherapy can help eliminate or control troubling symptoms so a person can function better and can increase well-being and healing. Problems helped by psychotherapy include difficulties in coping with daily life; the impact of trauma, medical illness or loss, like the death of a loved one; and specific mental disorders, like depression or anxiety. There are several different types of psychotherapy and some types may work better with certain problems or issues. Psychotherapy may be used in combination with medication or other therapies.
