Researchers often use computers in their experiments to keep from influencing the participants and to keep themselves <u>blind</u> regarding the conditions to which the participants have been assigned.
<h3><u>Why is research blinding crucial?</u></h3>
Blinding is crucial to prevent bias (such as observer bias and demand characteristics) and guarantee the internal validity of a study.
Participants may alter their behavior in ways that affect the outcome that researchers are aiming to measure if they are aware of whether they are in a control or treatment group. If those providing the treatment are aware of the participants' assigned groups, they may treat them differently, which could either directly or indirectly affect the outcome.

When Alzheimer disease sets in early and impacts those under age 60, death typically occurs around 3-5 years after the first signs of the disease appear.
Alzheimer's disease is a progressive neurological disorder in which the brain atrophies and brain cells die. Alzheimer's disease is the most common cause of dementia, a continuous decline in thinking, behavioral and social skills that affect a person's ability to be independent.
About 5.8 million people over the age of 65 in the United States have Alzheimer's disease. Of these, 80% are over 75 years. Of the approximately 50 million people with dementia worldwide, it is estimated that 60% to 70% have Alzheimer's disease.
