ove that,
although elation and depression were the commonest mood anomalies in
this group, they had no more theoretic importance than anxiety,
distressed perplexity or apathy. These other moods, although less
frequent, are just as characteristic of the psychoses in this group. In
other words, the name "Anxiety-Apathy Insanity" would be as appropriate,
theoretically, as Kraepelin's term. In 1919 Hoch and Kirby published a
report on the perplexity cases. This present book was designed to show
that the symptom complex centering around apathy is as distinct as that
which is recognized by all psychiatrists as mania with its predominant
characteristic of elation.

In 1917 ill health forced Dr. Hoch to resign from his official duties.
He retired to California with the purpose of adding to psychiatric
literature the fruits of his long experience and unrivaled judgment. His
first task was this book. In the midst of this work came a sudden
collapse. As I had been in close touch with his researches, cooperating
in psychological speculations, and was free to devote some time to it,
he asked shortly before his death that I complete the book. This
obligation is incommensurate with the debt I owe for years of
inspiration, tuition and criticism.

The task has been mainly literary. I found the first five chapters
practically completed, while it has not been difficult, as a rule, to
discover from his copious notes what his intentions were as to the
details of the following chapters. I have been greatly aided by the
assistance of Dr. Adolf Meyer and of Dr. Kirby. The latter has been good
enough to read the entire manuscript, making invaluable suggestions and
criticisms.
