Outcome for secondary preventive trials (in Mild Cognitive Impairment)

Preventive trials should first target specific patients' groups, and growing information concerning evolution of patients with mild cognitive impairments should be used for a proper selection. Studies on clinical evolution may also help to select appropriate neuropsychological tests, and prevention can be defined as maintained performance on a battery of tests. Disturbance of daily living activities should be considered since it defines occurrence of dementia. Complementary information can be obtained from behavioural evaluation.
