Communication and language
Ability to focus and pay attention
Reasoning and judgment
Visual perception

Many dementias are progressive, meaning symptoms start out slowly and gradually get worse.
If you or somebody you recognize is experiencing memory difficulties or different changes in thinking skills, do not ignore them.
See a doctor soon to determine the cause. Professional evaluation may detect a treatable condition.
And even though symptoms recommend dementia, early diagnosing permits someone to urge the most benefit from accessible treatments and provides a chance to volunteer for clinical trials or studies.
It also provides time to plan for the future.
