PIP reassessment due and need to be ready

Hi Gordon. On my PIP transfer from DLA the nurse asked can you read. I answered yes but then she dismissed the rest of my reply, my cognitive , concentration, poor memory etc (due to M.E and Fybromyalgia) on the reading description. She ticked I can read and understand. I thought you had to be able to understand what you had read, as it isn’t just a physical question but a mental one too? She stated as I haven’t a reported learning difficulty she is able to complete this task. I got no points. I was only 1 point off getting enhanced care. I was too ill to do an MR but as I am due to be reassessed due you think it will be ok for me to refer to the above to point out not aa the descriptor was taken into consideration? Also I didn’t send in any printouts of symptoms of M.E and Fybromyalgia as the form said not to.I assumed,wrongly, that my assessor would know the cognitive problems as a well known symptom of these 2 chronic conditions. A lot of patients/ medical professionals actually refer to it as fibrofog.? To me this is a contradiction as she said I could not plan the route of a journey as MSE shows lack of concentration etc. She also ticked claimant has a mental, intellectual or cognitive impairment and need additional support to comply with future claim processes. Can you explain what this means and how do you get additional support?
