Figure 1From: Neuropsychological measures of attention and memory function in schizophrenia: relationships with symptom dimensions and serum monoamine activity(Top) Serum monoamine and metabolite levels in controls (CON) and in patients treated with typical (TYP), atypical (ATYP) or both types of antipsychotic drug. Atypical > Typical, * P < 0.1; ** P < 0.08; *** P < 0.04; # P < 0.006 (covaried for age, IQ and CPZ). (Bottom) Turnover rates for 3 monoamines, and the ratio of dopamine (DA) to noradrenaline (NA) and serotonin (5-HT) metabolism (HVA/MHPG, HVA/5-HIAA), respectively. Controls (vs. whole patient group) showed less 5-HT TR (P < 0.05) and more HVA vs. 5-HIAA and MHPG (both ## P < 0.002).Back to article page
