DSM+II+1968

38 MENTAL DISORDERS
297.0 Paranoia
This extremely rare condition is characterized by gradual development
of an intricate, complex, and elaborate paranoid system
based on and often proceeding logically from misinterpretation of an
actual event. Frequently the patient considers himself endowed with
unique and superior ability. In spite of a chronic course the condition
does not seem to interfere with the rest of the patient's thinking
and personality.
297.1 Involutional paranoid state ((Involutional paraphrenia))
This paranoid psychosis is characterized by delusion formation with
onset in the involutional period. Formerly it was classified as a paranoid
variety of involutional psychotic reaction. The absence of conspicuous
thought disorders typical of schizophrenia distinguishes it
from that group.
297.9 Other paranoid state
This is a residual category for paranoid psychotic reactions not
classified earlier.
298 Other psychoses
298.0 Psychotic depressive reaction ((Reactive depressive psychosis))
This psychosis is distinguished by a depressive mood attributable to
some experience. Ordinarily the individual has no history of repeated
depressions or cyclothymic mood swings. The differentiation
between this condition and Depressive neurosis (q.v.) depends on
whether the reaction impairs reality testing or functional adequacy
enough to be considered a psychosis. (In DSM-I this condition was
included with the affective psychoses.)
