Okay, the user wants me to translate "developmental abnormalities" into Thai. Let me check the rules again. Rule 1 says to translate all content into Thai. Rule 2 says if it's already in Thai, leave it as is. Rule 3 is to provide only the translation without explanations.
First, I need to confirm that "developmental abnormalities" isn't already in Thai. The original text is in English, so I need to translate it. The correct Thai translation for "developmental abnormalities" would be "ความผิดปกติในการพัฒนา". I should make sure there's no typo and that the term is commonly used in medical or developmental contexts. Since the user specified only the translation and no explanations, I'll just output the Thai term without any additional text.
