What is a graphical symptom often noted in advanced stages of Alzheimer's concerning self-care?

In the advanced stages of Alzheimer's disease, individuals frequently exhibit a decline in their ability to perform basic self-care tasks, which typically includes neglecting personal hygiene and grooming. This neglect is often a result of cognitive impairment, as the disease progresses and affects memory, reasoning, and the ability to carry out daily activities.

People may lose the motivation or capacity to recognize the importance of maintaining hygiene, leading to missed bathing, hair care, and other personal grooming routines. As caregivers observe these changes, it's crucial to support the individual in maintaining as much independence as possible, while also recognizing the challenges posed by the disease.

The other options, while plausible in different contexts or stages of Alzheimer's, do not align with the common patterns seen during advanced disease progression. For example, excessive grooming or an over-attachment to products might occur in earlier stages or in specific individuals, rather than being a reliable symptom across the board.
