Mild cognitive impairment: potential pharmacological treatment options

Both mild cognitive impairment and age-associated memory impairment are terms used to describe memory decline in otherwise healthy, intellectually intact individuals aged older than 50 years. It is estimated that up to 38% of the middle-aged and older population fulfill diagnostic criteria for this condition. Although the memory deficits observed in these individuals are fairly mild, they can interfere with day-to-day functioning. This article presents a review of the types of memory decline observed in older people, the diagnostic criteria used to define memory decline, the physiological and morphological brain changes that accompany aging, and the potential pharmacological treatment options, focusing on agents that have been evaluated in mildly cognitively impaired or normal older populations.
