Advice re: heart attack, and liver problems

Hi Souter,
Your brother can certainly apply for a mobility award, but he won't get this unless he can demonstrate that he has poor walking ability ie less than 200m due to eg pain or breathlessness, or physical restriction. Alternatively if the mental health issues cause difficulties planning or following journeys he can gain points under the 1st mobility descriptor.
Certainly given heart problems and mental health issues, it seems likely that a mobility element could be awarded. However, you will need to consider individual descriptors and match these against the specific limitations that your brother has. You can find more information in the members' guides.
If your brother does fall within the descriptors and could achieve at least 8 points, then it may be worthwhile asking DWP for a review. Be aware that if you contact DWP for a review then this could mean having to have another assessment.
If you believe there is sufficient limitation to qualify you can get all the evidence in order before requesting the review. Medical evidence will be important so you can gather this now. Consider walking ability, where does pain/breathlessness etc kick in? Consider fatigue and what happens the next day/s. Maybe you can measure eg by pacing out a distance to confirm walking ability. Make a note of any falls/stumbles etc.
I hope this helps.
