Is it due to their physical problems or psychological? Is it due to their discomfort in psychical health or due to other people including cargivers don't understands what they say and hence getting irritated?
Persons with dementia have damage to their brains. (Different kinds of dementia equate to different kinds of damage.) Our brains control our behavior, and if there is damage the behavior can be damaged, too. If our view of reality is distorted our behavior will not appear reasonable or appropriate.
Most people with dementia do have some perceptions of the "real world" at least some of the time, but may not have the brainpower to cope or respond appropriately.
Certainly how persons and especially caregivers interact with persons who have dementia makes a difference. And learning to deal with dementia can go a long way in making things more pleasant for both the caregiver and recipient of care. But the brain damage is real and there are limitations to the dementia patient's control over behavior.
I agree, but, I also discovered that some behavior in a person who has dementia could be normal frustration. My cousin's Geriatric psychiatrist explained that there are often real reasons that we may see some agitation from the patient.
For example, if the patient is hitting the table with their hand. They may be bored and cannot verbalize it. Or maybe they are sitting near a loud person and they are annoyed. They may be impatient and are hungry for their lunch. That's why it's important to examine the circumstances and see whu the person may be experiencing outbursts. Of course, sometimes, the behavior cannot be traced to any particular reason.
