Dementia & Normal Aging
N ormal aging comes with a degree of cognitive decline across the population. This normal decline can affect processing speed (thinking speed), attention, memory and some executive functions like mental flexibility. Normal aging also involves a small amount of cerebral atrophy whereas dementia leads to a more dramatic atrophy.
Normal aging can cause forgetfulness but does not lead to dramatic memory loss. Memory loss is defined as the lack of ability to consistently recollect information. More importantly, dementia affects the daily activities of the person whereas normal aging does not.
