I would personally include undiagnosed conditions particularly if you can say there has been a referral for an assessment. Your application has to be stronger if it has been diagnosed, but nothing you can do about that. The fact that a referral has been made means that someone believes there is evidence of the condition. (It is also possible that by the time the assessment comes round there will be formal diagnosis.)
Remember PIP is about how your conditions affect you, not what the conditions are. So when it comes to completing the descriptors you really can’t leave out those effects out. If your son has certain difficulties because of a condition, whether or not it has been diagnosed, those difficulties are real and I can’t see why you would not include them on the form.
Well done for taking on helping your son with this. Not an easy task for either of you. And please, when you have finished and sent it off, spend some time together focusing on the positives of his life and what he can do!
