Recently, there is research on the brain’s reaction to AD as there is evidence of abnormal buildup in brains without the development of dementia. Scientists have linked resistance to dementia development to how effective the brain’s immune system is. Microglia is a key player in AD as it’s the brain immune system’s first line of defense. 

Dreams are weird, there’s no doubting it. They usually fall in a sort of uncanny valley, where the events that transpire feel realistic enough to be believable in the moment, but are much too fragmented when looking back. Thus, dreams may have people who are recognizable, or places which are familiar, but the exact details do not match. People might have different personalities, shifted voices, or even different appearances. To find out why this is, we have to look at the root cause of dreams.
