Dla mobility for behaviour

I'm sure I previous saw a check list somewhere giving guidance regarding requirement for getting mobility at the higher rate on behaviour.
I can't find it now.
My child presently gets higher mobility but I am doing the renewal and most info seems to be about physical difficulties

See DWP Guide A-Z of Medical Conditions

This medical guidance (for adults and children ) for Disability Living Allowance and Attendance Allowance Decision Makers has been developed by the Department's Health and Wellbeing Directorate with help from experts involved in patient care. It contains background information on the more common medical conditions in DLA/AA claims, their treatment, the likely disabling effects together with the likely impact on ability to self care and get around.

This guide is for staff who deal with claims for DLA and AA. It covers only the most common conditions they encounter – not all medical conditions.

There ls also information on DLA for both adult and children in our DLA Guides in the Members only area.
