Dementia is a decline of reasoning, memory, and other mental abilities, which are collectively called the cognitive functions. This decline eventually impairs the ability to carry out everyday activities such as driving, household chores, and even personal care such as bathing, dressing and feeding. Dementia affects about 1% of people aged 60-70 years. Dementia is different from age-related memory loss; a condition in which a person may not be able to find his glasses or remember someone's name, but will still be able to learn new things, solve problems, and carry out his everyday activities.
