Dementia vs Alzheimer's
Disease:
The most
important part of making a diagnosis is to obtain accurate information from
close family members and friends who know the patient well. We need to establish
that a decline in a level of functioning has occurred that cannot be explained
by depression or systemic illnesses such as renal or heart failure, and that the
process is progressively worsening. The baseline of each individual is unique
and determines the level with which we establish if there has been a
deterioration.
A urinary tract infection can cause major confusion in an
elderly person and should not be labeled as dementia. Pneumonia, head trauma and
medication side effects often cause memory problems too, but patients get better
over time and as such they do not meet the diagnostic criteria for
dementia.
Memory problems are ubiquitous and by themselves are not
worrisome for the onset of dementia. We all forget our keys, may have difficulty
finding our car in the garage, or walk into the basement and not remember why we
went there. Memory problems are concerning, and a sign of dementia, when a
patient forgets major events, names or things that are significant. Not showing
up at a daughter's wedding, forgetting names of grandchildren or not
remembering how to drive need to be evaluated for
dementia.
The common tests needed to establish a diagnosis of
dementia include:
- blood
tests for levels of B12 and thyroid
- brain
imaging with CT scan or MRI
- paper-pencil
tests to establish that there is a significant deficit in memory, learning,
language, orientation, and other brain functions such as drawing or abstract
thinking.
Treatment
Medications helpful for making a person with mild
dementia talk more, have more interest in interacting with family members, and
show less agitation or paranoid thoughts include Aricept, Razadyne and Exelon.
Aricept is the most commonly used drug in this class. It helps patients stay in
their own homes for a longer period of time and delay transfer to a nursing home
for two years or more. Numerous studies have shown the earlier treatments start
the more the patient benefits.
Patients who have increasing difficulty
with taking care of their basic needs such as getting dressed, eating or using
the bathroom benefit from taking a new drug called Namenda. Based on
clinical trials, patients with moderate to severe dementia benefit the most if
they take a combination of Aricept and Namenda together.
Care of Caregivers
It is
critical that caregivers of Alzheimer's patients take care of themselves too.
Often family members feel guilty for not spending enough time with the person
with Alzheimer�s (parents, grandparents, aunts, uncles, etc.) and end up giving up any free time they
have to care for him or her. Unfortunately, many caregivers experience a
great deal of stress, develop higher blood pressure and become depressed. They
need to balance their time such that they do not get burned out with taking on
all the responsibilities involved. The Alzheimer's Association offers many free
services to care for caregivers. You can get more information by visiting www.alz.org or
calling 1-800-272-3900. Reading "The 36-Hour Day" is a must for every
caregiver.
