In biology, aging is defined as the "gradual irreversible changes in structure and function of an organism that occur as a result of the passage of time."[1]
Cognition
Normal aging
Decline in executive control may occur with aging.[2] Loss of nonverbal skills, which can be measured by tests of clock drawing, may be especially important.[3]
Dementia
