US researchers have claimed that age factor is the major risk factor for Alzheimer's disease, as the age advances, the more the condition of the patient deteriorates. However, it has been suggested that elderly aged between 60 and 70s are the one, who are affected the most.
University of California, San Diego organized an Alzheimer's disease Neuroimaging Initiative, during which First author Dominic Holland of the University of California and colleagues used two different techniques that were imaging and biomarker data from the participants.
In total 732 people were analyzed, who were aged between 65 and 90 and each of them were diagnosed of either different levels of cognitive decline and in a few cases, the patients were completely affected by the disease.
Holland, asserted that people who have already reached the age of 85 are less likely to develop the condition or only 50% chances stay true. However, those in their 60s or 70s, diagnosed of the disease, are faster in developing the disease and its consequences, including brain tissue loss and cognitive decline
Holland said, “Cerebrospinal fluid biomarker levels indicate a greater disease burden in younger than in older individuals. It’s not clear why Alzheimer's disease is more aggressive among younger elderly”.
