F84

A normal start, then a loss of skills

A girl developed typically for her first year — babbling, reaching developmental milestones on schedule, and using a few early words. Over the following several months, she lost the words she had gained and stopped using her hands purposefully, now showing repetitive hand-wringing movements. Her paediatrician also notes her head circumference has been growing more slowly than expected on her growth chart since this change began.
