R. Douyon et al., SUBTLE NEUROLOGICAL DEFICITS AND PSYCHOPATHOLOGICAL FINDINGS IN SUBSTANCE-ABUSING HOMELESS AND NONHOMELESS VETERANS, The Journal of neuropsychiatry and clinical neurosciences, 10(2), 1998, pp. 210-215
This study evaluated the hypothesis that homeless individuals would di
splay higher levels of neurological deficits than non-homeless individ
uals, particularly in frontal lobe or executive functions. Eighteen ac
utely homeless, 15 chronically homeless, and 20 non-homeless individua
ls admitted to nn inpatient psychiatric service received a battery of
neurological and psychosocial measures. In comparison to non-homeless
subjects with comparable levels of psychopathology, homeless individua
ls showed higher levels of hostility, prior criminal activity, and fam
ily history of psychiatric illness, but lower levels of depression. A
positive relationship between hostility and neurological soft signs wa
s observed among chronically homeless subjects. These results suggest
that a substantial subset of nonpsychotic homeless veterans suffers fr
om ''occult'' neurological deficits.
