Apolipoprotein E genotype and odor identification in schizophrenia

J Neuropsychiatry Clin Neurosci. Spring 2006;18(2):231-3. doi: 10.1176/jnp.2006.18.2.231.


The authors examined Apolipoprotein E (ApoE) genotype frequencies and unirhinal odor identification in 28 schizophrenia patients and 26 healthy comparison subjects. No significant associations between ApoE status and olfaction were observed in either diagnostic group. The authors concluded that olfactory deficits in schizophrenia do not appear to be mediated by the ApoE allele.
