The genetics of neurological disorders

This excellent textbook was considered by eminent neurologists to be the then definitive publication on the genetics of neurological disorders, which was updated by Dr Mike Barraitser of G.O.S. in the 1970s and after him by Professor Anita Harding (now deceased). From what I recall, the principal illnesses here were the presenile dementias - but heck, what do I know, I was only the secretary!
