Take advantage of intervention services specialising in autism and intellectual impairment to develop and master basic skills for daily living. Our specialists are available to support children, adolescents and adults.

Tools to Better Manage Behaviours

The majority of children diagnosed with autism spectrum disorder (ASD) or general developmental delay (GDD), present with various learning disabilities. They need support to develop basic skills for daily living. Their difficulties in communication, interaction and socialisation cause them to have significant barriers in terms of their adaptation and social integration with peers. The objective of the ABA method is to equip them with the proper tools to better manage their behaviour in a minimal way so that they can successfully integrate into society.


ABA intervention consists of long-term strategies to assist children, teens and adults in setting up an independence that will allow social, academic and professional integration. This is done by allowing the client to develop basic learning skills (language, autonomy, movement, school, play, etc.) and to reduce behavioral disorders that impede these objectives (crying, aggressiveness, anxiety, etc.).

Marie-Ange Teyssier, Msc. neurophysiology

Specialist in Autism and Disability


Ms. Teyssier, Msc. Neurological Sciences, specializes in the development of communication and overall stimulation of children, adolescents and adults with autism spectrum disorder (ASD), intellectual disabilities, and/or developmental disorders.


She completed a Bachelor's degree in Biology at the University of Quebec in Montreal and a Master’s in Neurophysiology at the University of Montreal. Ms.Teyssier attended classes at the Doctoral level in Biomedical Sciences (child psychiatry option) at the University of Montreal. She then completed specialized training in ADS assessments at the Sainte-Justine Hospital during which she had the opportunity to participate in several research projects on autism. In addition, she received training in PECS (Picture Exchange Communication System) and participated in training sessions on autism offered by the Régie Régionale de la Santé et des Services Sociaux de Montréal-Centre (RRSSSMC). She also worked at the Centre d’éveil moteur Mallet as a specialist in ASD and scientific advisor in the development of early stimulation workshops and individualized intervention plans.


She has been working in this field for 19 years specializing in autism and developmental disorders offering stimulation services in-office, at home and in daycare, with young children, adolescents and young adults. Her interventions take into account the specific needs of the client and their family, their learning pace and sensory profile. In daycare settings (CPE), she supports educators by helping them integrate children with individual needs, to intervene with them by setting specific objectives adapted to each case, coaching them in how to effectively communicate with the child and providing them with activities and materials adapted to overcome or alleviate the child’s difficulties.


She is committed to working in close collaboration with the parents as well as the various professionals who are involved in the client’s care. Her aim is to provide parents and the client with tools and strategies to better adapt to their different living environments. She helps them to advocate for their rights and provides them with information on activities and organizations that allow them to carry out various learning opportunities and improve their social skills. It is for all these purposes that Ms. Teyssier joined the Centres Neuropsy team in 2019.
