The condition is also known as hebephrenia, named after the Greek term for "adolescence" – ἥβη (hḗbē) – and possibly the ancient-Greek goddess of youth, Hebe, daughter of Hera. The term refers to the ostensibly more prominent appearance of the disorder in persons around puberty. The prominent characteristics of this form are<unk>  behavior and speech (see formal thought disorder), including loosened associations and schizophasia ("word salad"), and flat or inappropriate affect. In addition, psychiatrists must rule out any possible sign of catatonic schizophrenia. The most prominent features of<unk>  are not delusions and hallucinations, as in paranoid schizophrenia, although fragmentary delusions (unsystemized and often hypochondriacal) and hallucinations may be present. A person with<unk>  may also experience behavioral disorganization, which may impair his or her ability to carry out daily activities such as showering or eating. The emotional responses of such people often seem strange or inappropriate. Inappropriate facial responses may be common, and behavior is sometimes described as "silly", such as inappropriate laughter. Sometimes, there is a complete lack of emotion, including anhedonia (lack of pleasure), and avolition (lack of motivation). Some of these features are also present in other types of schizophrenia, but they are most prominent in<unk> .
