Which scenario best describes an impact of aging on cognition? * edward has difficulty staying warm, even when it isn’t cold outside. * sylvia is unable to climb stairs as quickly as she used to. * albert is experiencing a large amount of grief as he ages. * donald is showing early signs of dementia.

The correct option is Donald is showing early signs of dementia

Dementia is a disease in which people lose the ability to remember things and symptoms associated with a decline in memory or other thinking skills strong enough to reduce a person's ability to perform everyday activities. Since dementia is directly related to the brain activities and Donald is showing these signs in early stages so the scenario best describes the impact of aging on cognition.
