Getting older, in and of itself, is not the cause of so-called â€œsenior momentsâ€. A new study found that even these mild memory lapses are caused by the same brain lesions associated with Alzheimerâ€™s disease and other dementias.
Researchers found that in the last four to five years of life, peopleâ€™s memory showed a very rapid decline. Pathologic lesions were found to be related to this rapid decline. The preceding years showed a much more gradual decline that was the actual result of normal aging.
According to Newswise:
“…Researchers looked at the rate of change in cognitive function over time. The last four to five years of life showed a very rapid decline. The preceding years showed a much more gradual decline that would be described as normal aging.
…Recognizing that the earliest changes in memory are related to Alzheimerâ€™s pathology can lead to early diagnosis and will be critical information if a treatment is developed that can alter the pathologic course of the disease.”
