Dementia is a progressive loss of cognitive function, marked by problems of memory and confused thinking. The more
the common form of dementia is Alzheimer's disease, a fatal condition that affects more than 5 million Americans

What is Alzheimer's disease?
Alzheimer's is a progressive brain disease that causes problems with memory, reasoning, behavior and motor skills.
Alzheimer's symptoms slowly worsen over time, and the disease is ultimately fatal.
Alzheimer's is the most common form of dementia, defined as a loss of cognitive functioning and
behaviors that interfere with everyday life. Other forms of dementia include vascular dementia, dementia
with Lewy bodies and frontotemporal dementia. Each of these diseases has its own set of specific symptoms.
The risk of Alzheimer's increases greatly with age. After reaching age 65, the risk of developing Alzheimer's doubles
approximately every five years, reaching almost fifty percent at 85 years. When the disease begins before age 65,
known as early-onset or early-onset Alzheimer's.
At this time, Alzheimer's disease has no known cure. Current medications only help decrease symptoms
providing temporary and partial relief, but with no real effect on cognitive impairment.
In addition to the emotional burden placed on patients and caregivers, Alzheimer's places enormous
families and health systems.
Dementia is not a specific disease. It is a general term that describes a wide range of symptoms associated with a
memory impairment or other thinking skills severe enough to reduce a person's ability to perform everyday activities.
Alzheimer's disease accounts for 60 to 80 percent of cases. Vascular dementia, which occurs after a stroke, is the
second most common type of dementia. But there are many other conditions that can cause symptoms of dementia,
including some that are reversible, such as thyroid problems and vitamin deficiencies.
Dementia is often incorrectly termed "senility" or "senile dementia," reflecting what has previously been widespread
but the incorrect belief that severe mental deterioration is a normal part of aging.
Common Types of Dementia, What is Alzheimer's Disease?
Loss of memory and other symptoms of dementia
Many people have memory loss problems – this does not mean they have Alzheimer's or other dementia
There are many different causes of memory problems. If you or a loved one is experiencing troubling symptoms,
visit a doctor to find out the reason. Some causes of dementia-like symptoms can be reversed.
Visit your doctor:
Although the symptoms of dementia can vary greatly, at least two of the following basic mental functions must be
significantly impaired to be considered dementia:
The memory is:
-Communication and language
-Easy to focus and pay attention
Reasoning and judgment
People with dementia may have problems with short-term memory, keeping track of a wallet or purse, paying bills,
planning and preparing meals, remembering appointments or traveling out of the neighborhood.
Many dementias are progressive, meaning that symptoms begin slowly and gradually worsen. If you or a loved one
you are experiencing memory difficulties or other changes in your thinking skills, do not ignore them. Consult a physician ready to
determine the cause. Professional assessment can detect a treatable condition. And even if the symptoms suggest
dementia, early diagnosis allows a person to derive maximum benefit from the available treatments and
opportunity to volunteer for clinical trials or studies. It also provides time to plan for the future.
10 Warning Signs, Alzheimer's Stages
Causes of dementia:
Dementia is caused by damage to brain cells. This damage interferes with the ability of the brain cells to communicate
together. When brain cells can not communicate normally, thinking, behavior and feelings can be affected.
The brain has many distinct regions, each of which is responsible for different functions (eg memory,
judgment and movement). When the cells of a region
