The brain controls many aspects of thinking — remembering, planning and organizing, making decisions, and much more. These cognitive abilities affect how well we do everyday tasks and whether we can live independently.
Some changes in thinking are common as people get older. For example, older adults may:
- Be slower to find words and recall names
- Find they have more problems with multitasking
- Experience mild decreases in the ability to pay attention
Aging may also bring positive cognitive changes. For example, many studies have shown that older adults have more extensive vocabularies and greater knowledge of the depth of meaning of words than younger adults. Older adults may also have learned from a lifetime of accumulated knowledge and experiences. Whether and how older adults apply this accumulated knowledge, and how the brain changes as a result, is an area of active exploration by researchers.
