Hi, I've passed the CTAX discount form on to GP together with copy of letter from consultant giving Vascular Dementia diagnosis. I've just had to make a phone appointment with GP next week so I am guessing it is about my request for her to sign letter. Has anyone's GP turned down their request? I know the term "Severe Mental Impairment" is a bit harsh but I used to deal with thousands of such requests while I worked at the council and as long as "Dementia" was on the form it was never queried. Interested to hear your experiences before I have my telephone chat next week.
