Since its first publication in 1978, and even more since having the second edition (1987), this prodigious compilation of clinically relevant information about the spectrum of neuropsychiatric entities and issues has been one of my most used reference books. Among its many virtues are its clarity of presentation, useful documentation, and coverage of just about all neurologic disorders that have behavioral (i.e., psychological and/or psychiatric) implications. I would not have wanted to practice or write without the current edition of Lishman at hand.
