Answer:
They may be startled if you approach them from behind.
Explanation:
The statement "They may be startled if you approach them from behind" best describes a person with dementia in one of the later stages.
As dementia progresses, individuals may experience increased confusion, disorientation, and sensory impairment, making them more prone to being startled or frightened by sudden movements or unexpected approaches. The other statements do not typically align with behaviors observed in later stages of dementia.
