I know someone who is the same age as myself, we share the same neurologist, and were both diagnosed with the same condition at the same time. As advised we both informed the DVLA that we had Parkinson's Disease, yet he was never made to be retested. The fact that we are both at the same stage of having the disease is neither here nor there. All you tell the DVLA is that you have whatever condition, not how it affects your ability to drive.

There does seem to be an awfull lot of varience as to who is considered disabled, either to be regularly retested, or to qualify for the blue parking badge.
