Alzheimer's disease is the most common form of dementia among older people. It involves the parts of the brain that control thought, memory, and language. Alzheimer is an irreversible disorder, and even though progress has been made in detecting the disease at an earlier stage, for earlier diagnosis and prevention efforts, there is still no cure.

So how can you tell if someone you know have begun to develop Alzheimer? Usually it starts with slight forgetfulness. Then the person asks the same question over and over again and repeats the same story, word for word. The person can also forget recent events and how to do simple tasks.

Argument: According to National Institutes of Health in the US, 13.2 million Americans will have Alzheimer's disease by 2050, while the US population by then will be 419 million (US Census Bureau).

Questions: Since a lot of stress is put on families where a person has been diagnosed with Alzheimer, what will this increase in people with Alzheimer do to the society in general, when a higher percentage of the population has to become caregivers?
