Monomania

High Quality Content by WIKIPEDIA articles! In 19th century psychiatry, monomania (from Greek monos, one, and mania, mania) is a single pathological preoccupation in an otherwise sound mind. Emotional monomania is that in which the patient is obsessed with only one emotion or several related to it; intellectual monomania is that which is related to only one kind of delirious idea or ideas. In 1880, monomania was one of the seven recognized categories of mental illness. After the 1850s monomania faded as a diagnostic category in psychiatry, and does not appear in the Diagnostic and Statistical Manual of Mental Disorders. However, a number of disorders once classified under monomania survive as impulse control disorders or conduct disorders or delusional disorders.
