By breaking complex skills into small steps, children can systemically learn to respond and behave in socially appropriate ways.

(NoteABA is now widely seen as abusive for those on the Autism spectrum.)

Neurofibromatosis Type 1 (or NF1): A neurological condition in which excess synapses grow along neurons within the body — which can cause tumours to form around major nerves — and outside the body as external tumours, moles or skin tags attached to nerve endings. Suspected by many researchers of sharing the same genetic cause as Autism Spectrum Disorder, it is a common co-morbidity in people with ASD/ASx. It often manifests itself in early childhood as a pale “café au lait” stain on the skin.

show the following features:
• An obsessive resistance to ordinary demands and requests
• Use of socially manipulative or outrageous behaviour to avoid demands
• Sudden changes in mood apparently associated with a need to be in control/autonomous
• ‘Surface’ sociability, reflected in social peculiarity, difficulties with peers and lack of

Self-help skills: Daily skills such as self-feeding, dressing, bathing, and other tasks that are necessary to maintain health and well-being.

Self-stimulatory behaviors: Also called stereotypy, and present in both autistic and neuro-typical individuals, these are repetitive body movements, such as flapping arms or rocking back and forth, or repetitive movements of objects, like spinning wheels or opening and closing doors.
