Indications of reduced prefrontal cortical function in chronically homeless adults.

This study investigated why some homeless individuals seem unable to transition towards self-reliance, following traditional supportive services. It was hypothesized that this may be due to some cognitive dysfunction. Chronically homeless adults were compared to controls on three tests of prefrontal competency: the Iowa Gambling Task, Word Fluency (FAS), and the Burglar's Story; they performed significantly worse than controls on all three tests. These results indicate a relationship between chronic homelessness and possible pre-frontal deficits. This may explain why some long-term homeless fail to learn from the consequences of unproductive behavior and to develop more constructive behaviors needed to attain stability.
