Paragraph 2
Researchers looked at
from a health and retirement
of 18,154 adults over the age of 50. The participants were dementia-free at the
of the 16-year research. Everyone was asked
two years about their mental
, and about how long they spent online. The
found that those who were
for two hours a day were
as likely to have signs of dementia than those who were never online. They also found that
Internet use (6 to 8 hours a day) may increase the
of dementia.
