And in Morocco?

Practical steps depend on the country: disability card, health coverage, inclusive schools. Read our practical guides: disability card for a child in Morocco, autism diagnosis in Morocco, inclusive schools in Casablanca and speech therapy in Morocco.

Frequently asked questions

What are the main types of disability in children?

They are usually grouped into: neurodevelopmental disorders (autism, ADHD, language and learning disorders), intellectual disability (including Down syndrome), motor disability, and sensory disabilities (visual and hearing). One child can have more than one type.

Can a disability appear after birth?

Yes. Some disabilities are genetic or present from birth; others appear later due to an accident, illness or premature birth. Regular pediatric follow-up helps detect developmental delays early.

Why does the exact diagnosis matter so much?

The precise term (autism rather than "intellectual disability", dysphasia rather than "late talker") changes which professionals to see, which approaches work, which aids are available and what schooling is possible. It also protects families from "miracle" methods sold on vague labels.
