ESA award paper work sent with PiP review paperwork

Hi, my PiP review form has arrived and in taking my time to read as much info as possible in completing this a question has come to mind.
I finished work in 2017 due to being unable to continue my profession and I was placed in the ESA support group straight away with no face to face assessment.
I was diagnosed with Parkinson’s in 2006.
I have never included this information in my PiP review forms previously, possibly niavely, thinking that PIP dept would be aware.
I’m not sure if this would have made any impact or not.
On initial application for DLA (some years ago ) I was awarded middle rate for daily living and high for mobility, which enabled me to have a car through the mobility scheme.
However when I was transferred from DLA to PiP I lost both rates, on request of re consideration I was awarded standard rate for both daily living and mobility.
I have been unable to be assessed as requiring the higher rate award for either component since.
I am not expecting that by including my ESA decision, awarded back in 2017 to change anything previously but should I make them aware now?
My Parkinson’s has progressed, as is the nature of the illness, and any other advice or experiences would be most appreciated. Thank you
