Dementia is a general term covering a wide spectrum for a decline in mental ability which offers challenges to daily living. It can manifest mainly in difficulties in memory. Alzheimer's is the one of the more commonly and widely known types.

​

However, dementia is not a specific disease. It's an overall term that describes a wide range of symptoms associated with the decline in memory or other thinking skills severe enough to reduce a person's performance. 

 

Alzheimer's disease accounts for 60 to 80 percent of cases. Vascular dementia, which occurs after a stroke is the second most common type. But there are other conditions that may be the cause of symptoms of dementia. 

 

Identifying Symptoms of Dementia
While the symptoms of dementia can vary greatly, at least two of the following core mental functions must be significantly impaired to be considered dementia. 

• Memory

• Communication and language

• Ability to focus or pay attention

• Reasoning and judgment

• Visual perception 

​

It is important to note that many people have memory loss issues but it does not mean they may have dementia. It is recommended to visit a doctor to learn the reason.

Looking out for Persons with Dementia
Many dementias are progressive, meaning it starts slowly and gradually gets worse. If you or a loved one experience problems with short-term memory, keeping track of a purse of wallet, paying bills, planning and preparing meals, remembering appointments or travelling, don't ignore them. An evaluation will help you get the maximum benefit of any treatments and help you plan for the future.
