Identify the causes of Alzheimer's behavior problems
Problem behavior is often a way the Alzheimer’s patient tries to communicate with you. The progression of the disease means that they may no longer be able to communicate verbally, but they are still emotionally conscious and will remain so, often until the very end of life.
In many cases the patient’s behavior is a reaction to an uncomfortable or stressful environment. If you can establish why the patient is stressed or what is triggering their discomfort, you should be able to resolve the problem behavior with greater ease. Remember that the person with dementia is not being deliberately difficult. Their sense of reality may be different to yours, but it’s still very real to them.
Some ways to help identify the causes of problem behavior:
- Try to put yourself in the person's situation. Look at their body language and imagine how they might be feeling and what they might be trying to express.
- Ask yourself what happened just before the problem behavior started? Did something trigger the behavior?
- Are the patient’s needs being met?
- Does changing the environment or the atmosphere help to comfort the person?
- How did you react to the problem behavior? Did your reaction help to soothe the patient or did it make the behavior worse?
Causes of Problem Behavior
Create a calm and soothing environment
As a caregiver, you may not be able to control the person you’re caring for. However, if you’re caring for your loved one at home, you can control the environment and the atmosphere you create while caregiving. These factors play a large part in helping an Alzheimer’s patient feel calm and safe.
- Modify the environment to reduce potential stressors that can create agitation and disorientation in the Alzheimer’s patient. These include loud or unidentifiable noises, shadowy lighting, mirrors or other reflecting surfaces, garish or highly contrasting colors, and patterned wallpaper.
- Maintain calm within yourself. Getting anxious or upset in response to problem behavior can increase stress or agitation within the patient. Respond to the emotion being communicated by the behavior, not the behavior itself. Try to remain flexible, patient, and relaxed. Remember, the patient is responding to your tone of voice and body language more than the content of what you’re saying. If you find yourself becoming anxious or losing control, take a time out to quickly relieve stress.
Manage stress in an Alzheimer’s patient
Different stress-reducing techniques work better for some Alzheimer’s patients than others, so you may need to experiment to find the ones that best help your loved one.
- Exercise is one of the best stress-relievers for both the Alzheimer’s patient and you, the caregiver. Consult with your loved one’s physician to make sure they’re safe to participate in light exercise. Regular walking, movement, or seated exercises can have a positive effect on many problem behaviors, such as aggression, wandering, and difficulty sleeping. Indoor shopping malls are vast walking opportunities protected from the weather. Or you may even consider singing and dancing.
- Simple activities can be a way for the patient to reconnect with their earlier life. Someone who used to enjoy cooking, for example, may still gain pleasure from the simple chore of washing vegetables for dinner. Try to involve the person in as many productive daily activities as possible. Folding laundry, watering plants, or going for a drive in the country can all help to manage stress.
- Use calming music or play the person’s favorite type of music as a way to relax them when agitated. Music therapy can also help soothe the person during mealtimes and bath times, making the processes easier for both patient and caregiver.
- Interacting with other people is still important. While large groups of strangers may only increase stress levels for an Alzheimer’s patient, spending time with different people in one-on-one situations can help to increase physical and social activity.
- Pets can provide a source of positive, nonverbal communication. The playful interaction and gentle touch from a well-trained, docile animal can help soothe an Alzheimer’s patient and decrease aggressive behavior. If you don’t have a pet of your own, see Related Links for organizations that offer pet visits.
While wandering around the house may be irritating to you as the caregiver, it’s not necessarily unsafe for the patient. Some wandering, though, can be dangerous: going into areas of the house such as stairwells, decks, hot tubs, or swimming pools; leaving the house alone via a window or door; or leaving your yard or property.
Two characteristic precursors to wandering are restlessness and disorientation. An Alzheimer’s patient may exhibit signs of restlessness when hungry, thirsty, constipated, or in pain. They may also become disoriented, pace, or wander when bored, anxious or stressed due to an uncomfortable environment or a lack of exercise. To address this you can:
- Immediately redirect pacing or restless behavior into productive activity or purposeful exercise.
- Make sure the Alzheimer's patient gets plenty of regular physical exercise and movement.
- Reassure the person if they appear disoriented.
- If wandering tends to occur at a particular time of day, distract the person at that time.
- Reduce noise levels and confusion. These can disorient the person.
- Acclimate ahead of time if you move the patient to a new environment by making several visits.
- Consult the doctor if disorientation is becoming a problem. Disorientation can be a result of medication side effects, drug interactions, or over-medicating.
Practical ways to prevent wandering
You may be able to prevent many instances of wandering by:
- Installing child-safety devices in your home to keep doors and windows secured.
- Hiding items like purses, shoes, or glasses that the person would always take with them if they left the house.
- Acquiring comfortable chairs that restrict movement, making it difficult for the patient to stand up without assistance.
Planning for when the Alzheimer's patient does wander
In case an Alzheimer’s patient in your care does wander, it’s a good idea to have a plan in place. Notify neighbors and local police about your Alzheimer's patient’s tendency to wander, and ask them to call you if they see your elder wandering without supervision.
If a police search becomes necessary, you’ll need a recent photo of the person’s face. Also keep on hand some of their unwashed clothing to help search-and-rescue dogs. (To do this properly, place the clothing in a plastic bag with plastic-gloved hands, and replace this clothing monthly.) Another smart preventative measure is to sign up for the Alzheimer’s Association’s Safe Return Program in the U.S., an identification system to help rescue lost Alzheimer's patients who have wandered away (see Resources and References below).
Where to look for a lost Alzheimer's patient
A person with dementia may not call out for help or answer your calls, and often won’t leave many physical cues. He or she may get stuck in a place that they cannot get out of, leaving them at risk for dehydration and hypothermia.
How to find a missing Alzheimer’s patient
- Check dangerous areas near the home, such as bodies of water, dense foliage, tunnels, bus stops, high balconies, and heavily traveled roads.
- Look within a one-mile radius of where the patient was before they wandered.
- Look within one hundred feet of a road, as most wanderers start out on roads and remain close by. Especially look carefully into bushes and ditches, as the person may have fallen or become trapped.
- Search in the direction of the wanderer’s dominant hand. People usually travel first in their dominant direction.
- Investigate familiar places, such as former residences or favorite spots. Often, wandering has a particular destination.
- If you suspect that the person used a car or public transportation, you’ll need to consider likely places that are farther afield.
Caring for a patient who rummages around or hides things in the home is a challenge, but not an insurmountable one.
Protecting your property
- Lock certain rooms or cabinets to protect their contents, and lock up all valuables.
- Have mail delivered out of reach of the Alzheimer's patient--perhaps to a post office box.
- If items do disappear, learn the person’s preferred hiding places and look there first to find hidden objects.
- Restrict access to wastebaskets and trashcans, and check all wastebaskets before disposing of their contents, in case objects have been hidden there.
Protecting Alzheimer’s patients from harming themselves
- Remove or prevent access to unsafe substances, such as cleaning products, alcohol, firearms, power tools, sharp knives, and medications.
- Prevent electrical accidents by blocking unused electrical outlets with childproofing devices. Hide stove knobs so the person can’t turn on the burners.
- Lower the temperature on water heaters.
- Designate a special drawer of items that the person can safely “play” with when keen torummage.
While creating a calm environment can have a large impact on managing the stress that often results in aggressive behavior, there are also some things you can do during an angry outburst from the Alzheimer’s patient.
- Don’t confront the person or try to discuss the angry behavior. The person with dementia cannot reflect on their unacceptable behavior and cannot learn to control it.
- Do not initiate physical contact during the angry outburst. Often, physical contact triggers physical violence in the patient.
- Provide the person with a “time-out” away from you. Let them have space to be angry by themselves. Withdraw in the direction of a safe exit.
- Distract the person to a more pleasurable topic or activity.
- Look for patterns in the aggression. Consider factors such as privacy, independence, boredom, pain, or fatigue. Avoid those activities or topics that anger the person. To help find any patterns, you might keep a log of when the aggressive episodes occur. If the person gets angry when tasks are too difficult for them, break down tasks into smaller pieces.
- Let the person play out the aggression. Just be sure that you are safe and that they are safe themselves.
- Get help from others during the activities that anger the patient.
- Don’t take the aggressiveness personally.
Hallucinations can be the result of failing senses. Maintaining sameness and calmness in the environment can help reduce hallucinations. Also, violent movies or television can contribute to paranoia, so avoid letting the patient watch disturbing programs.
When hallucinations or illusions do occur:
- Don’t argue about what is real and what is fantasy.
- Discuss the patient’s feelings relative to what they imagine they see.
- Respond to the emotional content of what the person is saying, rather than to the factual/fictional content.
- Seek professional advice if you are concerned about this problem. Medications can sometimes help to reduce hallucinations.
Alzheimer’s and suspicion
Confusion and the loss of memory can also cause an Alzheimer’s patient to become suspicious of those around them, sometimes accusing their caretakers of theft, betrayal, or some other improper behavior.
- Offer a simple answer to any accusations, but don’t argue or try to convince them their suspicions are unfounded.
- Distract the patient with another activity.
- If suspicions of theft are focused on a particular object that is frequently mislaid, such as a wallet for example, try keeping a duplicate item on hand to quickly allay the patient’s fears.
Brain disease often disrupts the sleep-wake cycle. Alzheimer's patients may have wakefulness, disorientation, and confusion beginning at dusk and continuing throughout the night. This is called “sundowning.”
There are two aspects to sundowning. First, confusion, over-stimulation, and fatigue during the day may result in increased confusion, restlessness, and insecurity at night. And second, some Alzheimer's patients have fear of the dark, perhaps because of the lack of familiar daytime noises and activity. The patient may seek out security and protection at night to alleviate their discomfort.
Ways to reduce nighttime restlessness
- Improve sleep hygiene. Provide a comfortable bed, reduce noise and light, and play soothing music to help them get to sleep. If the person prefers to sleep in a chair or on the couch rather than in bed, make sure they can’t fall out while sleeping.
- Keep a regular sleep schedule. Be consistent with the time for sleeping and keep the nighttime routine the same. For example, give the person a bath and some warm milk before bed.
- Keep a night light on. Some people with dementia imagine things in the dark and become upset. Stuffed animals or a pet may also help soothe the patient and allow them to sleep.
- Place a commode next to the bed for nighttime urination. Walking to the bathroom in the middle of the night may wake the person up too much, and then they can’t get back to sleep.
- Increase physical activity during the day to help the person feel more tired at bedtime.
- Monitor napping. If the person seems very fatigued during the day, give them a short rest in the afternoon to regain their composure. This can lead to a better night’s sleep. But don’t let them sleep too long – too much daytime napping can increase nighttime wakefulness.
- Limit the patient’s caffeine intake during the day.
Resolve common problems
If the patient paces during the night, make sure that the primary daytime caregiver can sleep. This requires either a very safe room for the patient to pace in, or else another caregiver who takes over at night. You need your rest, too. Do not restrain the patient in bed, but consider a hospital bed with guard rails in the later stages of Alzheimer’s. If night wakefulness has gotten too hard for you to manage, consult with a doctor if you wish to try administering sleeping pills.
Try one or several of the following suggestions to care for a patient who won’t eat:
|Managing an Alzheimer’s patient who refuses to eat|
Encourage some exercise - Exercise can make a person feel hungrier: The hungrier the person feels, the more likely they are to eat.
Monitor medications - Some medications interfere with appetite. Read about the side effects of any medications that the Alzheimer's patient is taking. Discuss with the doctor the lack of interest in eating; you may need to change a medication.
Make sure that the person gets enough liquids with their food, as dry mouth may be a side-effect of some medications.
Make mealtimes pleasing to the patient - If the Alzheimer's patient does not like the person who is feeding them, they may not feel like eating. Try a different caretaker for the feeding process.
Make the patient’s favorite food, and serve food on colored tableware—dishes that contrast highly with food colors. Reduce distractions in the eating area.
Also, avoid foods that are too hot or too cold, as these may be unpleasant to the patient.
Feed the patient like a baby - Try giving the patient little spoonfuls, and sing short, funny rhymes to get them to eat. Get the person to smile so that the mouth opens, and then slip a little food in their mouth. Or put a bit of the food on the person’s lips so that they open their mouth wider.
Provide finger foods and children’s sipper cups, as the person may have trouble using utensils and normal cups.
Monitor chewing and swallowing - Chewing and swallowing difficulties can develop as Alzheimer's progresses. If necessary, give instructions on when to chew and when to swallow. Keep the person upright for thirty minutes after eating so that they don’t choke.
Transition into providing only puréed or soft foods - In the later stages of Alzheimer's, the person can no longer swallow food and may choke on food. Swallowing problems can lead to pneumonia because the patient may inhale food or liquid into the lungs.
Begin feeding only liquids to the patient when the time is right.
Caregiving for a loved one with dementia can be extremely demanding and stressful. Each day can bring more challenges and higher levels of anxiety. Unfortunately, when you’re stressed and fatigued, you lose the ability to remain calm and soothing, and the patient will inevitably pick up on those negative feelings. This in turn can add to the patient’s own levels of stress and increase their problem behavior.
Taking care of yourself and getting help and support is essential for both your well-being and your loved one’s quality of life. Respite care can provide a break to help you relieve stress and restore energy.
