Editorial: Exploring Reliable Markers and Prediction Indexes for the Progression From Subjective Cognitive Decline to Cognitive Impairment

Editorial on the Research Topic Exploring Reliable Markers and Prediction Indexes for the Progression From Subjective Cognitive Decline to Cognitive Impairment Alzheimer's disease (AD) is a neurodegenerative disorder and the most common cause of dementia. A growing body of evidence shows that SCD may be one of the earliest noticeable symptoms of AD and related dementias. [...]it is required to explore reliable biomarkers and prediction indexes for patients with high progression risks from SCD to cognitive impairment. Taking this into consideration, the Research Topic “Exploring Reliable Markers and Prediction Indexes for the Progression from Subjective Cognitive Decline to Cognitive Impairment” by Frontiers in Aging Neuroscience makes a contribution with updates and different perspectives on this important theme, developed over 19 papers. The study by Shi et al., explores whether adenosine receptor 1 (A1 R) is involved in electroacupuncture (EA) pretreatment induced cognitive impairment after focal cerebral ischemia in rats.
