Entorhinal cortex hypometabolism may also be considered a warning sign as in elderly people with normal cognition it can predict the progression to mild
Progressive reduction of glucose metabolism can be detected years before the appearance of clinical symptoms of AD, as verified in postmortem studies [9]. FDG-PET is therefore capable of providing information on disease progression from predementia states, such as MCI, to AD [19]. In the early stages hypometabolism may be unilateral, followed by bilateral spreading later on [28]. Analysis of MCI subjects in a study by Drzezga et al. revealed significantly lower metabolism of bilateral posterior cingulate cortex and right precuneus [8]. Entorhinal cortex hypometabolism may also be considered a warning sign as in elderly people with normal cognition it can predict the progression to mild

found decreased entorhinal cortex glucose metabolism at baseline to be the most accurate regional predictor of clinical change, as well as of further neocortical temporal lobe and hippocampal involvement, suggesting an “entorhinal cortex” stage of brain pathology that can be detected in normal elderly [18].
cognitive impairment or even AD [7]. Mosconi et al. found decreased entorhinal cortex glucose metabolism at baseline to be the most accurate regional predictor of clinical change, as well as of further neocortical temporal lobe and hippocampal involvement, suggesting an “entorhinal cortex” stage of brain pathology that can be detected in normal elderly [18]. Such findings suggest that FDG-PET may be useful in prevention studies for individuals at risk for dementia in the preclinical stage of Alzheimer’s disease [4]. The identification of asymptomatic individuals at risk could be even more important should an effective neuroprotective agent that can delay or prevent progression to AD become available in the future [7].

Grid cells are discovered in 2005 by Edvard and May-Britt Moser and are found mainly in the entorhinal cortex.
The navigational system of the brain is a complex synaptic system comprised of characteristic cell populations, named place cells and grid cells. Place cells are discovered in 1971 by John O’Keefe and are localized in the hippocampus. Grid cells are discovered in 2005 by Edvard and May-Britt Moser and are found mainly in the entorhinal cortex. These two cell populations have functional differences and form the so-called “internal GPS”. Place cells are responsible for dynamically changing specific locations (place fields). Grid cells control the current navigation by integrating information about the body position, the direction and speed of movement.
