Understanding the neurobiology of Fragile X syndrome and behaviours (Dr Marcia Braden)
Presented by psychologist Marcia Braden PhD, this overview lays the foundations for understanding and supporting the neurological underpinnings of behavioural presentations associated with Fragile X syndrome. This was the introductory presentation by Dr Braden for a live Q&A webinar on supporting behaviours in young children with Fragile X syndrome, produced by Fragile X Association of Australia in collaboration with Fragile X New Zealand on 13 July 2025.
This presentation outlines:
* the genetic basis of Fragile X syndrome
* the neurological impact on cognition and behaviours which is caused by the lack of/reduced FMR1 protein for many individuals with Fragile X syndrome
* neurological basis of traits associated with Fragile X syndrome: high anxiety; weakened short-term memory and attentional control; hyperactivity; and reduced executive function
* overview of strengths and challenges in daily living associated with Fragile X syndrome
* overview of behaviours which may result from the high levels of anxiety experienced by individuals with Fragile X syndrome
* impact of elevated hyperarousal associated with Fragile X
* neurological underpinnings of the behavioural cycle and interaction with the responses from parents/caregivers
* reference to the ABCs of behaviour (Antecedent, Behaviour, Consequence) in supporting behaviours resulting from the neurobiology of Fragile X syndrome. This webinar/Q&A was presented on 13 July 2025, and hosted for Fragile X Association of Australia by Andrea Lee, Executive Director of Fragile X New Zealand.
