Reading Alzheimer's Patients' Behavior: It Takes a Detective
The friends and family of the 4.5 million Americans living with Alzheimer’s
disease often essentially lose their loved one before he or she dies. That’s
because people with this form of dementia gradually slip into a fog of memory
loss and confusion. Not only is Alzheimer’s disease emotionally wrenching for
caregivers, but it can also be frustrating.
As the disease progresses, people with Alzheimer’s lose the ability to reason
and can develop difficult and sometimes aggressive behaviors. While some
caregivers have found their grandfather stealing from drugstore shelves, others
have tales of their mother calling them at work 35 times a day or of a husband
kicking and screaming in order to avoid brushing his teeth. These situations can
try the patience of the calmest caregiver, but not taking such behavior
personally and employing certain strategies can help.
Causes of Behavioral Changes
If a caregiver notices significant behavioral changes, experts say it is
important to have the person with Alzheimer’s quickly assessed by a healthcare
professional to make sure that there is no underlying pain or discomfort. "A
patient with severe dementia may not be able to tell you they’re having
abdominal pain, so it may just manifest as agitation." says Dr. Marc L. Gordon,
chief of neuroscience at North Shore Long Island Jewish Health System in Great
Neck, New York.
Kathleen O’Brien, senior vice president of programming and community services at
the Alzheimer’s Association, says that "being a good caregiver is about being a
good detective." Besides agitated behavior, other clues that someone might be in
pain include a grimacing facial expression or squirming. Agitated behavior may
also be a sign of a urinary tract infection, a reaction to medication or simply
hunger or thirst.
An over-stimulating environment, a change in living arrangements or in
caregivers, or frustration with not being able to handle a simple task can also
provoke an agitated episode. That’s why intimate personal care issues such as
bathing can turn into nightly stand-offs. "If the person feels like their
self-esteem or dignity is being compromised, that can create a volatile
situation." O’Brien says.
Validate and Distract
While it’s tempting for caregivers to correct someone with Alzheimer’s, experts
say that trying to reason with someone who has this disease will get you nowhere
fast. Instead, caregivers can often defuse a difficult situation by adopting a
soothing tone and redirecting the person’s attention. For example, if bathing is
a problem, O’Brien suggests using a lavender- or rose-scented bubble bath. Such
relaxing fragrances may even help trigger memories or distract the person by
engaging their senses. If the person enjoyed music before his or her illness, a
caregiver might play some favorite tunes during a bath to reduce the stress
associated with bathing.
Dr. Alan Dengiz, director of geriatric medicine at St. Joseph Mercy Hospital in
Ann Arbor, Michigan, offers another common challenging scenario and possible
solution. "One of the things that happens, especially as the day progresses, is
that the individual with Alzheimer’s disease will say, ’I want to go home’ when
they’re in their home. What they’re thinking about oftentimes is a home from
their past because that’s what’s still alive in their brain, whereas the current
home is not as familiar to them because they’ve lost the more recent memories."
"What I recommend is that you go along with that rather than trying to correct
them and getting them angry." Dengiz continues. "You can say, ’Well, let’s go
home later on, but why don’t we go into the kitchen and have a nice cup of tea
and just sit down and relax?’ Sometimes that’s enough to do it."
Creating structure by developing a schedule that includes meaningful activities
can also reduce stress and agitated behavior. For example, people in the early
stages of the disease can go on outings to the symphony, baseball games or
social dances offered by local chapters of the Alzheimer’s Association. Physical
activity such as tai chi may also relax people with Alzheimer’s disease and help
them sleep better.
People with more advanced dementia may benefit from art or music therapy, which
can help them tap into their memories and express their feelings and creativity.
"Art therapy gets people to think and do things that they might not ordinarily
do." Dengiz says. "That helps to stimulate the more artistic side of the brain.
It also gives those individuals something to be very proud of."
Dengiz adds that, in his experience, Alzheimer’s greatest impact on the
dominant, logical side of the brain. So this may allow people to view things in
a less preconceived way and enable them to create colorful and abstract art
work, similar to children’s art.
For some people with Alzheimer’s, distractions and activities may not be enough
to control challenging behavior. These people may require medication to treat
their agitation and allow them to function better, especially if they have
underlying psychosis, depression or anxiety. Medications, such as
antidepressants, anti-anxiety drugs and anti-psychotics, can be very helpful not
only to the patient but also to a fatigued caregiver.
To avoid burnout caregivers need to remember to give themselves a break. They
shouldn’t feel guilty about asking for respite care so they can have a few days
or weeks off. It might also be helpful to join a support group.
Still, caregivers and people with Alzheimer’s will always have their good days
and their bad days. "One of the important things for caregivers to understand is
that frustrating or challenging behavior is a result of the disease and brain
cells dying, and it’s not reflective of the person." O’Brien says. "If families
recognize that, it’s easier to find a way to manage."
