Difficult behaviors
can make caring for someone with Alzheimer's and other kinds of dementia a
challenge. One way to approach this is to try to determine the cause of those
behaviors so that we can respond more appropriately. All behaviors have
meaning, so by figuring out what may be causing the behavior, we can hopefully
address the unmet need underneath it.

1. 10 Physical Causes of Challenging Behaviors:
As we look at various
causes, consider physical causes. Physical (or biological) issues, such as
discomfort or hunger, can cause people with dementia to act out or resist care.
Discomfort or Pain
Sometimes behaviors
are caused by physical discomfort or pain. For example, if your mother has pain
that is unnoticed, she may become restless, anxious or resist being moved or
cared for.
Hunger or Thirst
Some people with
Alzheimer’s wander around, searching for a snack or a drink. If your loved one
needs more snacks or drinks, keep food out on the counter that's safe and easy
to eat. You can also fill a covered cup with ice water and a straw and set it
out on the counter. This may prevent wandering or restlessness.
Poor Nutrition
As opposed to actively
seeking food or drinks, some people don't take in enough food. Perhaps your
father lives on his own and is trying to be as independent as possible. He may
report that all is well, but unexplained weight loss or a tour of his kitchen
may reveal this isn’t the case. Poor nutrition can increase confusion and cause
such behaviors as apathy or resistance to care. Older adults with early
dementia often struggle with planning and making meals, and may not be getting
adequate nutrition. If your father is still able to manage the other areas of
living independently, try looking into such services as senior meals or
meals-on-wheels to assist with meeting his nutritional needs.
Dehydration
Dehydration is closely
linked with poor nutrition. Some people intentionally avoid drinking lots of
water because they struggle with incontinence. Others simply forget to drink
water throughout the day. Dehydration can cause decreased awareness,
disorientation and increased confusion, increasing the risk of wandering and
other behaviors. Depending on what medications your loved one is taking, proper
hydration can be especially important because some medications can build up in
the body and become toxic.
Fatigue
Being overly tired can
also result in challenging behaviors. We all have less patience and tolerance
when we’re tired, and it’s the same for the person with dementia. Poor sleep
can certainly trigger behavior challenges in dementia, especially because
people may lack the inhibition to temper their feelings of irritation or
crankiness.
A Need for Exercise
Did your mother get
some exercise today? If not, she may need to go for a walk or stretch her legs.
Building in a time for exercise, even if it’s just walking through the house or
the halls, can decrease restlessness.
A Need to Use the Bathroom/Incontinence
Perhaps your loved one
is attempting to get up again out of her chair, after you’ve reminded her many
times to stay seated so she won’t fall. Rather than getting frustrated with her
and viewing her as stubborn, consider that she might not be able to find the
words to express her need for the bathroom or to convey that she is uncomfortable,
wet and in need of a new incontinence pad and change of clothes.
Urinary Tract Infection
A urinary tract
infection (UTI), sometimes called a bladder infection, can dramatically affect
behavior. If someone shows a sudden change in behaviors, be sure to investigate
this as a possible cause. Other symptoms of a UTI include cloudy urine, pain while
urinating (so watch for grimacing while your loved one is using the bathroom),
foul smell and fever.
Sensory Impairments
Does the person you’re
caring for have a deficit in hearing or vision? This can increase his anxiety
since he might be startled by your nearness or touch. Be aware of this deficit
and compensate for it by approaching the person from the front, speaking into
the ear that has better hearing or gently touching him on the arm to indicate
your presence.
Decreased Ability to Communicate Needs or
Preferences
Deficits in
communication can range from mild difficulties with finding the right words to
a complete inability to make needs known. This can cause feelings of
helplessness and frustration, which in turn can trigger a behavior problem. Being
intentional in adhering, as much as possible, to preferences and routines can
help minimize this frustration.
2. Psychological/Cognitive Causes of
Challenging Behaviors in Dementia - How Feelings and
Thoughts Affect Behavior
Challenging behaviors
are often among the more difficult aspects of coping with Alzheimer's and other
dementias. As we consider how to reduce these behaviors, which can be
distressing to both the person with dementia and the caregiver, it can be
helpful to evaluate the possible psychological and cognitive causes. These
include the person's emotions and thoughts.
Psychological and Cognitive Causes:
Boredom
Is your loved one
bored? Maybe he needs some more routine in the day or more mental stimulation
and interaction with others. Boredom can cause people with dementia to act out
negatively or withdraw and become apathetic. If you're the caregiver for
someone with dementia, try structuring his day by providing a regular time for
games, conversation and physical activity.
Loneliness
Loneliness can also
trigger certain behaviors in dementia, such as wandering, sexually
inappropriate acts, aggression or agitation.
Sundowning
Sometimes, people with
dementia may experience an increase in agitation or restlessness as evening
approaches. Research hasn’t conclusively shown why this is, but it’s called
sundowning since behaviors often get worse in the evening as the sun sets.
Keeping a quiet routine and several lights on in the house may help.
Frustration with a Loss of Control
Some people become frustrated,
angry or aggressive because they're aware of the need to depend on others for
many things. They may have lost the ability to administer their own
medications, make decisions or care for themselves. Often, they're not able to
express this clearly by saying, "I'm so frustrated because I feel like
everyone is telling me what to do and where I have to go." But those
feelings may be present inside. If you sense someone is frustrated, it can be
helpful for you to acknowledge this occasionally by saying with a smile,
"I'm sorry to be the bossy daughter, mom" or simply, "Are you
feeling frustrated?"
Hallucinations/Paranoia/Delusions
Unfortunately, people
with Alzheimer’s often experience hallucinations (seeing or hearing something
that is not present), paranoia, or delusions. If someone is not in touch with
reality, it’s best not to argue or try to persuade him that he’s incorrect. Arguing
can increase his frustration and anxiety since he may feel that his fears are
not being taken seriously.
Confusion About Reality
While it seems obvious
that confusion can be the cause of behavioral concerns, we need to remember
that dementia affects that brain. Someone may act or react inappropriately
because they don't understand the situation. For example, if a nursing aide is
bathing a resident at a long-term care facility, the resident may not
understand that he needs that assistance with physical care and may
misinterpret it. If you have the television on at home, pay attention to what
is on. Even if you think of it as just background noise, your loved one might
not know that the TV show isn’t real and could react to it in an anxious or
aggressive manner.
Depression
Depression is a
significant cause of challenging behaviors. Feelings of sadness and
hopelessness can cause apathy (a lack of motivation and feelings of
listlessness), and can also cause an increase in confusion. In fact,
pseudodementia, a condition where depression blunts emotions and thoughts to
the point where it appears the person has progressive dementia, can develop.
Anxiety
Often, anxiety and
depression go hand in hand with a dementia diagnosis. These feelings may be
difficult to identify at times because the person may have trouble expressing
them. Observe for signs of anxiety, such as pacing, worried facial expressions,
repetitive questions or statements, hand-wringing, etc., and report them to his
physician.
Catastrophic Reaction
A catastrophic
reaction is when someone significantly overreacts to something or someone.
Perhaps you have ruled out many other causes and yet the behavior, such as
physical aggression, continues. It’s possible that it’s a catastrophic reaction
to events or stimulation that the person just can’t comprehend; perhaps it's
triggering a past negative experience. Your best approach, after ensuring her
safety, is to remain calm and reassuring, give her some time and physical space
and then return to provide her care after she is calm. You can also try to
determine if there's a pattern to her reactions that you could change by
approaching her differently.
3. Environmental / External Causes of
Challenging Behaviors in Dementia
Many of the behavioral
concerns that arise in Alzheimer's and other dementia have specific causes. In
order to effectively address and reduce some of those challenging behaviors, we
need to first consider what might be causing the person to behave that way.
One way to approach
this is to look at what's happening around, and outside of, the person with
dementia. Evaluating the setting can help us determine if there are situations
that may be triggering a behavioral reaction by someone whose memory,
comprehension or orientation is limited.
Environmental Causes of Challenging Behaviors:
Overwhelmed by Stimulating Surroundings
Are there too many
choices, is it too noisy or is more than one person speaking at the same time
to your mother with Alzheimer’s? These are examples of situations that can be
overwhelming for someone with dementia. She can’t process everything as well as
she used to, so if the environment is too busy, this can trigger anxiety,
frustration, anger or withdrawal.
Change in Routine
If your usual routine
with your loved one is to rise mid-morning and eat a hot breakfast, getting up
at 8 a.m. to rush off to an early doctor’s appointment might be difficult. Take
this into consideration; when possible, keep consistency in the routine.
Unfamiliar Environment
Changing someone's
usual environment can trigger such behaviors as restlessness, aggression and
agitation. For example, when your loved one is admitted into the hospital,
provide extra reassurances through your presence and through verbal reminders
like, "It's going to be okay; I'm here with you." You can also offer
comforting touch such as holding his hand (if this is something that usually
calms the person).
Lack of Personal Space
Everyone has a
personal bubble of space they’re used to keeping as their own. Individuals with
Alzheimer’s or another dementia may have an increased sensitivity to a person
coming into their space or a decreased awareness of others’ space.
Confrontation with Others
Sometimes, other
people unknowingly trigger uncooperative or aggressive behavior in others with
dementia. For example, in a facility, one person who is confused may not
realize that another person is also confused, and this may unknowingly trigger
a reaction of anger or frustration.
Caregiver Approach
This is a critical
factor in the behavior of those with Alzheimer’s or other dementias. If the
person receiving care feels rushed, patronized or unimportant, this can easily
trigger frustration that shows up as resistance, hitting or verbal aggression.
Focusing on how caregivers approach someone and interact with them is one of
the most effective ways to manage and reduce challenging behaviors in dementia.
