Final answer:
Individuals with dementia may exhibit unacceptable behaviors due to difficulty with communication, disorientation, and changes in personality and judgment. The severity of these behaviors varies with the progression of the condition, affecting their ability to comprehend and follow the rules of their care environment.
Step-by-step explanation:
A person with dementia may indeed exhibit various unacceptable behaviors, which can be associated with a multitude of factors brought on by the condition. Some behaviors could be the result of difficulty with communication, often due to their struggle in articulating thoughts or understanding others. Disorientation in time and place, coupled with a loss of recognition for familiar faces and environments, can result in a lack of understanding of policies or recognition of the inappropriateness of certain actions within a facility. Moreover, dementia patients may have trouble with planning and executing tasks, which includes following the established routines or rules set by care institutions.
Adding to these problems are potential personality changes, which can make individuals with dementia appear irritable or stubborn, possibly leading them to act out or wish to 'do their own thing' contrary to the communal setting rules. Finally, the progression of dementia can manifest in ways that diminish a person's judgment and decision-making abilities, resulting in actions that may be deemed unacceptable in their living or care environment.
