Abstract |
To examine the prevalence of the Paraoxonase1 (PON1) gene 192Q/R polymorphism amongst Singaporean Chinese with Alzheimer's disease (AD) and mixed dementia and possible clinical associations. We examined the presence of the PON1 192Q/R polymorphism together with cognitive status, functional status and neuropsychiatric symptoms among 186 older Singaporean Chinese with AD (n = 109) and mixed dementia (n = 77). The R allele predominated in 67% of the AD patients and 63.1% of the patients with mixed dementia. Within the mixed dementia subgroup, the R allele was significantly associated with a higher BADLS score, NPI-Q scores and CDR scores. Among older Singaporean Chinese with AD and mixed dementia, the R allele was predominant. In particular, within the mixed dementia subgroup, the R allele carrier status was associated with poorer functional status, greater presence of neuropsychiatric symptoms and a more severe stage of dementia. Further studies should be conducted. |
