Friend is in her 70s and has got DLA since being injured in a car accident many years ago. She gets higher rate mobility and lower rate care. She's got forms to try to get the middle rate care. She's very disabled - can only walk a very, very short distance on crutches, needs help with all the bathroom/kitchen stuff etc so sure she must qualify, but are there any 'buzz' words/phrases she needs to mention to ensure she states her case properly?
