10 signs that a moment of forgetfulness may be something more serious

TORONTO - Deciphering the difference between symptoms of dementia and regular aging is the basis for Cogniciti's new online "brain checkup," set to launch this fall. But there are also other hints that can indicate whether a moment of forgetfulness is a sign of something more serious.

Here are 10 things to watch for that could indicate someone is developing Alzheimer's or another form of dementia:

1. Memory lapses that affect day-to-day functioning.

2. Difficulty performing familiar tasks.

3. While everyone may occasionally forget a word, people with Alzheimer's may struggle to put together sentences.

4. Becoming lost and disoriented.

5. Displaying poor judgment, such as wearing a coat on a hot day.

6. Difficulty completing tasks that require abstract thinking, such as balancing a cheque book.

7. Anyone can occasionally misplace their keys, but someone with Alzheimer's may leave things in inappropriate places, such as putting their wallet in the fridge.

8. Experiencing violent mood swings for no apparent reason.

9. Alzheimer's may change someone's personality and leave them acting out of character.

10. Losing initiative and becoming very passive may also be a sign.
