Neurodevelopmental disorders are diagnosed predominantly in children and youths. They include Autism Spectrum Disorders, Attention Deficit Hyperactivity Disorder (ADHD), Down Syndrome and Obsessive Compulsive Disorders. Personality disorders are characterised by a lack of healthy adaptability and coping mechanisms for responding to stressful situations. There are three main clusters of personality disorders: paranoid, schizoid and schizotypal personality disorders; impulsive personality disorders; and anxious personality disorders. Further information on neurodevelopment disorders is available from the Province of Ontario Neurodevelopmental Disorders (POND) Network, and information on personality disorders is available from the Centre for Addiction and Mental Health.
