简要总结
Dementia represents a serious public health challenge for elderly people, while Alzheimer’s disease (AD), the most common type of dementia, has become one of the biggest mental burdens . Except for the recent and controversial approval of Aduhelm to treat patients with Alzheimer’s disease, there are no effective treatments to prevent or delay its progression, only for treating the symptoms of mild to moderate dementia. Therefore, there is an urgent need to identify effective strategies to prevent dementia. It is well recognized that mild cognitive impairment (MCI) precedes AD ; however, new evidence suggests that subtle and silent pathological brain changes associated with subjective decline are also present in subjects with subjective cognitive decline (SCD), defined as a self-reported decline in cognitive performance compared to an individual’s previous level of functioning, which cannot be determined by neuropsychological tests and precedes objective cognitive decline
Mild cognitive impairment (MCI) most simplistically defined refers to cognitive changes in the absence of dementia. It has been likened to an intermediate stage between normalcy and dementia. Indeed, the entity probably stemmed from the pursuit of clinicians to try and find the missing piece of the puzzle between so called “normal†elderly and the elder with dementia.
Reisberg in 1988 first described an entity with Global Deterioration Scale Score (GDS) of 3. Subsequently, Flicker and colleagues wrote an article on patients at risk for dementia, also with GDS scores of 3. Of course, it was Peterson in 1997, who then termed this entity as Mild Cognitive Impairment or MCI.
Currently approved treatment for MCI is purely symptomatic. Registered symptomatic treatment consists of acetylcholinesterase inhibitors (AchE-Is) and memantine. AchE-Is in general.
There is an ongoing effort in the development of more effective symptomatic treatment options, new compounds which are natural extracts with a potential to improve the symptoms of cognitive decline in aging adults are in the center of interest in the research field. However, no natural extract supplement with a robust data has proven the potential to improve the symptoms, restore the cognition and cease the progression into AD is presently available, has been designed to evaluate in improving existing mild cognition deficits and the ability to better perform activities of daily living which would provide a substantial benefit to patients.
