CDKL5 Deficiency Disorder — NDIS Support

Yes — CDKL5 Deficiency Disorder can qualify for NDIS support. Children may access support through early childhood intervention, based on developmental need rather than a fixed diagnosis. Funding covers reasonable and necessary supports across daily living, therapy, social participation and capacity building.

CDKL5 Deficiency Disorder (CDD) is a rare genetic condition caused by changes in the CDKL5 gene, which makes a protein essential for normal brain development. It is a form of developmental and epileptic encephalopathy, meaning both frequent seizures and significant developmental delay are part of…

CDD & the NDIS FAQs

Is CDKL5 Deficiency Disorder eligible for the NDIS?
Children with CDD have severe, permanent developmental disability from early infancy, so they are very likely to meet the NDIS disability requirements. Children under 7 can use the early childhood approach, which focuses on developmental need and doesn't require a fixed diagnosis to begin support. A genetic diagnosis…
When should support for a child with CDD start?
As early as possible. Because CDD affects development from the first months of life, early childhood intervention — physiotherapy, occupational therapy, speech pathology and developmental support — is important from infancy. Starting early helps build skills, manage complications and set up the equipment and…
Can the seizures in CDD be treated?
Seizures in CDD are often drug-resistant, meaning they respond poorly to standard anti-seizure medicines. Teams may try combinations of medications, dietary therapy such as the ketogenic diet, and other approaches, and newer treatments are emerging. Even so, many children continue to have seizures, so specialised…
How does CDD affect communication?
Most children with CDD are non-verbal or have very limited speech, and many also have cortical visual impairment. Communication is usually built through alternative and augmentative communication (AAC) — eye-gaze systems, switches, symbols and communication devices. Speech pathology is central to helping children…
What ongoing supports do children with CDD need?
Support needs are high and lifelong. They typically include skilled personal care, therapy across physio, OT and speech, assistive technology and custom seating, help managing feeding and health complications, and family respite. Support coordination helps families manage the large medical and therapy team involved in…
