Capstones
It can be hard getting help for someone with mental illness, but almost impossible when that person doesn't think they are sick. At at least half of people with schizophrenia, for example, insist that the voices they hear are real. People who do not know they are ill often refuse therapy and medication -- and their symptoms can spiral out of control. Doctors call this lack of awareness anosognosia. Neurologists are trying to discover what causes this baffling condition--and how to treat it.

Changes in brain reward systems are thought to contribute significantly to the cognitive and behavioral impairments of schizophrenia, as well as the propensity to develop co-occurring substance abuse disorders. Presently, there are few treatments for persons with a dual diagnosis and little is known about the neural substrates that underlie co-occurring schizophrenia and substance abuse. One goal of the present study was to determine if a change in the concentration of kynurenic acid (KYNA), a tryptophan metabolite that is increased in the brains of people with schizophrenia, affects reward-related behavior. KYNA is an endogenous antagonist of NMDA glutamate receptors and …
