title: Negative symptoms in chronic non-schizophrenic patients.
abstract: Negative symptoms are mostly associated with schizophrenic illness. This paper discusses the presence of negative symptoms in other chronic psychiatric illnesses. We have observed that longitudinally primary negative symptoms tend to be constant and are precisely symptoms which can define chronicity. They are as unspecific as positive symptoms in mental illness.
