Some change in memory is normal as we grow older, but the
Alzheimer's disease are more than simple lapses in memory.
People with Alzheimer's experience difficulties communicating,
learning, thinking and reasoning - problems severe enough to have
an impact on an individual's work, social activities and family
The Alzheimer's Association has developed a checklist of common
symptoms to help you recognize the difference between normal
age-related memory changes and possible warning signs of
There's no clear-cut line between normal changes and warning
signs. It's always a good idea to check with a doctor if a person's
level of function seems to be changing. The Alzheimer's Association
believes that it is critical for people diagnosed with dementia and
their families to receive information, care
and support as early as possible.
10 Early Warning Signs of Alzheimer's Disease

meal, placing a telephone call or playing a game. What's
typical? Occasionally forgetting why you came into a room or
what you planned to say.
- New Problems with Writing or Speaking

substitute unusual words, making their speech or writing hard to
understand. They may be unable to find the toothbrush, for example,
and instead ask for "that thing for my mouth." What's

neighborhood, forget where they are and how they got there, and not
know how to get back home. What's typical? Forgetting the
day of the week or where you were going.

layers on a warm day or little clothing in the cold. They may show
poor judgment, like giving away large sums of money to
telemarketers. What's typical? Making a questionable or
debatable decision from time to time.

able to retrace steps to find it later.

confused, anxious, suspicious or dependent on a family member.
What's typical? Occasionally feeling sad or moody.
- Trouble Understanding Visual Images and Spatial

distance and determining color or contrast, which may cause
problems with driving. What's typical? Vision changes
related to cataracts.

themselves from sports, social events and hobbies. They may become
passive, sitting in front of the TV for hours, sleeping more than
