Abstract

Mental Retardation (MR) affects nearly 1-3% of the population and often goes with comorbid psychiatric disorders. According to the literature, bipolar affective disorders are among the least studied psychiatric disorders in MR. Focusing more on MR than other psychiatric disorders and for mentally retarded persons, difficulty in explaining their signs and symptoms might interfere with considering affective disorders in this population. In this case report, we present a male patient who has MR with comorbid bipolar affective disorder with manic attack, and his treatment process.

Key words: Mental retardation, bipolar affective disorder, lithium
