Condition information

Developmental regression

Regression means losing a skill a child could previously perform and should be assessed promptly.

What families may notice

  • Loss of words, interaction or play skills
  • Loss of walking, hand use or self-care skills
  • New seizures, unusual movements or marked behaviour change

How assessment may help

The pattern and speed of loss guide urgent investigation. Families should bring a clear timeline, videos and previous developmental or school reports.

The child’s own pattern matters. Similar symptoms can have different causes, and tests are selected only after considering the history and examination.

What to bring

  • A referral letter and previous medical reports
  • A current medicine and dose list
  • EEG, MRI or CT reports and the actual images where available
  • School or therapy reports relevant to the concern
  • Safe phone videos of typical episodes, without delaying care or placing the child at risk

Planning the next step

Contact the practice for a non-urgent appointment request. Sudden, severe or rapidly worsening symptoms should be assessed through an emergency service rather than an online form.
