Rs. Kahn et al., NEUROPSYCHOLOGICAL CORRELATES OF CENTRAL MONOAMINE FUNCTION IN CHRONIC-SCHIZOPHRENIA - RELATIONSHIP BETWEEN CSF METABOLITES AND COGNITIVE FUNCTION, Schizophrenia research, 11(3), 1994, pp. 217-224
Schizophrenia is associated with multiple cognitive deficits which in
turn may be related to abnormal dopamine (DA) function. To examine pos
sible associations between cognitive dysfunction and central DA activi
ty in schizophrenia, neuropsychological measures (visuospatial and ver
bal recall; performance on the Wisconsin Card Sort Test (WCST); visuos
patial perception) were examined in 17 drug-free male schizophrenic pa
tients and related to cerebrospinal fluid concentrations of the metabo
lites of dopamine (homovanillic acid (HVA)), serotonin, and norepineph
rine. CSF HVA concentrations were correlated with the ability to recal
l visuospatial information, with attention to verbal tasks, and with W
CST performance (low CSF HVA concentrations predicting poor performanc
e on these tests) but not with the ability to recall verbally presente
d material and visuospatial perception. These data are consistent with
earlier results suggesting that (cortical) DA function is associated
with recall and retrieval of visuospatial information and with WCST pe
rformance.
