Step-by-step explanation:
An individual with Alzheimer's Disease (AD) who cannot recognize family members or self in the mirror is likely in the moderate stage of the disease. This stage exhibits increased memory, language, and cognitive deficits compared to the mild stage. Symptoms such as inability to recognize family members, wandering, agitation, and difficulty with daily activities are characteristic of this stage. In the most advanced phase, severe AD, patients lose virtually all ability to communicate or recognize their surroundings and require full-time care.
