What Proactive Semantic Interference and Persistent PSI Can Reveal About Cognitive Status: Rosie Curiel, PsyD
The associate professor of neuropsychology at the University of Miami Miller School of Medicine provided insight on how persistent impairments seen on a cognitive screening tool may differentiate cognitive status. [WATCH TIME: 6 minutes]

"The CST in particular goes a step further to say, ‘OK, for individuals who are susceptible to this failure to recover from proactive semantic interference, why don’t we give them another chance?’ We want to make sure that this cognitive breakdown is an entity in and of itself, independent from initial learning capacity."
A better understanding for the early signs and symptoms of conversion in late-life cognitive stages can be critical when developing a prevention plan. Previous research has identified proactive semantic interference as a potential early feature of incipient Alzheimer disease (AD), while there has been little research into retroactive semantic interference (frRSI), in AD and amnestic mild cognitive impairment (aMCI). A new innovative tool, the Cognitive Stress Test, assesses a patient’s ability to recover from frRSI through multiple word lists.

The investigators, including Rosie Curiel, PsyD, also concluded that deficits in PSI, frPSI, and persistent frPSI suggested that these impairments are not solely a function of initial learning ability. Curiel, an associate professor of neuropsychology at the
