Representative Publications

Snitz BE, Wang T, Cloonan YK, Jacobsen E, Chang CH, Hughes TF, Kamboh MI, Ganguli M. Risk of progression from subjective cognitive decline to mild cognitive impairment: The role of study setting. Alzheimers Dement. 2018; 14(6):734-742.

This study suggested subjective cognitive decline (SCD) is more likely to progress to mild cognitive impairment (MCI) in a specialty memory clinic setting than a population study setting. Thus, study setting should be considered carefully when evaluating SCD as a risk state for MCI or dementia.

Wu F, Wang T. Risk assessment of upper tract urothelial carcinoma related to aristolochoic acid. Cancer Epidemiol Biomarkers Prev. 2013; 22(5):812-820.

A systematic review and meta-analysis were performed and found aristolochic acid exposure is associated with increased risk of upper tract urothelial carcinoma. 

Snitz BE, Small BJ, Wang T, Chang CH, Hughes TF, Ganguli M. Do subjective memory complaints lead or follow objective cognitive change? A five-year population study of temporal influence. J Int Neuropsychol Soc. 2015; 21(9):732-742.

A population-based cohort study to investigate the temporal relationship between subjective memory and objective cognition and found the two reciprocally influence each other over time.
