PHILADELPHIA: New research shed’s light on brain’s progression from mild cognitive impairment (MCI) to Alzheimer’s-type dementia by showing the typical patterns.
The study showed that different cognitive areas (language, inhibition, visuo-spatial processing, working memory, executive functions, etc) do not change in a uniform way. Cognitive decline does not occur in a linear fashion; instead, the path to dementia is complex and may sometimes be characterised by periods of stability followed by accelerated decline one or two years before diagnosis.
Researchers have identified a profile of changes that characterises people who progress towards dementia.
