Dear John Baker, As far as I am aware, there is only one centre in England that performs pallidotomies, and that is somewhere in the Midlands (Birmingham, Manchester or Leeds - I can't remember which) In March 1995 Bob Archer mailed the PD list to tell us that his mother had just had the first pallidotomy in the UK ; it may be worth contacting him about the details of this operation here (email: [log in to unmask]) As for recommending a physician, one of the leading Parkinson specialists here (perhaps *the* leading specialist in the UK) is Dr A.J. Lees, who can be found at The National Hospital for Nervous Diseases, Queen's Square, London ; it should be possible to get a referral for your mother-in-law to see him if you feel she is up to the travelling. My dads PD (he's 66, diagnosed 6-7 years ago) has been well managed by Dr Lees ; certainly by comparison to some of the medical horror stories you occasionally hear on this list Hope your trip goes well (at least the weather may be good !)
