Neuroticism combined with slower and more variable reaction time: synergistic risk factors for 7-year cognitive decline in females.

Objective: Among adults, slower and more variable reaction times are associated with worse cognitive function and increased mortality risk. Therefore, it is important to elucidate risk factors for reaction time change over the life course. Method.
