What is dementia? 

Dementia is a broad term, generally used to indicate memory loss and confusion in the elderly population. It can be caused by a head injury, problems with the vascular system, such as a stroke, or Alzheimer’s disease. Alzheimer’s disease is the most common cause for dementia, accounting for nearly 70% of all dementia cases. 

What are the signs and symptoms of Alzheimer’s disease?

Caregivers need to stay healthy and take the time to take care of themselves so that they can provide excellent care to their loved ones.
