What this study looked at
CLN2 disease (a form of Batten disease) is a rapidly progressive childhood condition that is usually picked up once seizures prompt a referral. This study examined language and communication development in affected children to test whether early language delay might be an even earlier clue to the diagnosis.
Key takeaways
- Language development is frequently affected early in CLN2, sometimes before other symptoms appear.
- Recognising subtle language delay could shorten the path to diagnosis.
- The findings support treating language delay together with seizures as a red-flag pattern in children aged two to four.
Why it matters
In a disease that progresses quickly, every month saved before treatment begins can help preserve a child's function.
