Which of the following is a behavior often seen in clients with dementia?

Tangential thinking is a behavior frequently observed in clients with dementia. This phenomenon involves a tendency to veer off topic or provide responses that are only loosely relevant to the conversation, which can make interactions challenging. In individuals with dementia, cognitive impairments disrupt logical progression of thoughts, leading to difficulty in maintaining a coherent line of thinking.

Preservation refers to the repetition of a specific response or behavior and is also associated with cognitive impairments but is more distinctly related to conditions like obsessive-compulsive disorders rather than dementia specifically. Thought blocking involves an abrupt halt in the flow of speech, which is typically connected to mood disorders or psychotic conditions rather than dementia. Introjection, on the other hand, is a psychological defense mechanism where individuals internalize the beliefs and values of others, which is not a common behavior seen in patients with dementia.

In summary, tangential thinking represents a pertinent cognitive struggle associated with dementia, reflecting the disorganization and decline in logical thought processing that characterizes this condition.
