Part of a current wave of history, The LGBT Casebook is the first book to bring the unique needs of its eponymous clients front and center. The book begins with an explanation of how modern this history is, with discussion of the use of the colloquial term “coming out.” Many readers of the text will find themselves older than the LGBT (lesbian, gay, bisexual, and transgender)-based use of the term, which dates back to the 1960s. These same readers will remember that homosexuality itself was not fully depathologized until two decades later in 1980, with the publication of DSM-III. With this casebook, psychiatry finally finds itself walking toward—to meet and understand—the LGBT experience. The editors do a wonderful job of covering this rapidly changing cultural topography, ranging from more recent changes, such as the repeal of “don’t ask don’t tell,” to the ongoing national debate concerning marriage equality, with its resulting legal uncertainties. Drs. Levounis, Drescher, and Barber cover the significant ground yet to be gained and address how this affects our clients and their families. As such, this book is a needed addition to help therapists deal with LGBT-related issues.
