Do you mean the Towers? If so, then yes, you may well strike lucky if you visit the records office.
My ancestor was one of the first intake into the Towers when it opened and I found her details very quickly in the admissions book. This lists (from memory,don't have my photocopy to hand) the name of the patient, when they were first admitted, whether it was their first admission, the address from which they were admitted, their diagnosis and their discharge or death date.So it's not masses of info but to me, even that much was a great find.
When I got this info, the records had not been indexed (and as far as I know this is still the case- someone will say if I'm wrong!) so you will have to request the original book to be brought out of the backroom then be prepared to spend some time flicking through.
Good luck!
