Professor R. E. Cawley,
Institute of Psychiatry.
Dear Professor Cawley,
I am writing to you in your capacity as chairman of the meeting on the benzodiazepines held at the Medical Research Council on Wednesday 23rd September 1981. I am enclosing some additional information which I would have presented at that meeting if it had then been available, I understand that you are presenting the report of that meeting to the Neurosciences Board in the near future and you may consider that my supplementary information could be included.
As you will see from the table, 2 of our 14 patients have definite cortical atrophy, 5 have a borderline abnormality and the rest are normal. However, I am led to believe that the analysis of the radiologist was fairly crude and that more refined techniques might reveal further problems. Accordingly I think that the amount of abnormality is probably an underestimate. *
Several of the patients are still on benzodiazepines but some have been off for quite some time.
Yours sincerely,
cc Dr. James
Dr. Sturgess
