Assessment

Primary outcomes

The changes of ADAS-cog scores between baseline and 48-week/ 96-week after intake of rosmarinic acid

Key secondary outcomes

(1) Comprehensive effects: The changes of CDR-SB scores between baseline and 48-week/ 96-week after intake of rosmarinic acid
(2) Efficacy of prevention on the developing dementia: The incidence of dementia defined as Major neurocognitive disorder in DSM-5
(3) The total volume of the hippocampus: The changes of the total hippocampal volume quantified by MRI between baseline and 96-week after intake of rosmarinic acid
(4) Activities of daily living: The changes of Barthel index and IADL scores between baseline and 48-week/ 96-week after intake of rosmarinic acid
(5) Neuropsychological evaluation: The changes of MMSE scores between baseline and 48-week/ 96-week after intake of rosmarinic acid
(6) Safety of rosmarinic acid: To evaluate safety of long-term intake of rosmarinic acid. Including incidence of adverse event, vital signs, laboratory examination, and head MRI.
(7) The changes of biomarkers (blood amyloid-beta protein etc) and the association between biomarkers and cognition (ADAS-cog score etc)
(8) Compliance rate: The differences of the results of Primary and Secondary outcomes for each compliance rate
