This is the sort of area where your DD could fall down:
"42192 The judgment states that the DM must consider whether a substantial risk arises in the light of the work which the person might be expected to perform in the workplace he might find himself in. In making this assessment, the DM need only identify a broad range of duties that the person could be capable of, taking into account any training given, the person?s aptitude and their disease or disablement.
Example 1
Peter is 27 years old and suffers from alcohol dependency syndrome. He has never worked and says that his condition prevents him from undertaking any kind of work. The DM identifies that Peter could undertake straightforward and unstructured, unskilled work without substantial risk to himself or any person. The DM need not identify a particular type of work that Peter could be capable of.
Example 2
Phillip is 22 years old and has recently been diagnosed as suffering from epilepsy. Since the age of 18 he has worked as a roofer and scaffolding erector. Phillip says that if he were to return to this work, his health would be at substantial risk as he was often expected to work at great height. The DM determines that Phillip could now undertake closely supervised, indoor or outdoor work, at ground level without risk to himself or any person. The DM need not identify a particular type of work that Phillip could be capable of."
So, the assessor could say '2old2bemum's DD could do any work where she has a high level of support, doesn't have to read or write, doesn't have to move much so that her asthma isn't triggered, involves regular rests so that she doesn't get dizzy." It doesn't matter if this sort of work doesn't exist! It would be enough for them to put her in the work group
