Final answer:
Withdrawal from social activities is a later symptom of Alzheimer's disease, related to the more severe stage where dementia becomes prominent.
Step-by-step explanation:
Withdrawal from social activities is a later manifestation of Alzheimer's disease. During the early stage of Alzheimer's disease, the patient begins to present with signs such as disruptive memory loss, confusion about time or place, and difficulty with planning and executing tasks. As the disease progresses, more severe symptoms such as slowed movements, balance and posture problems, and rigid muscles appear. Ultimately, psychological symptoms such as dementia become more pronounced, leading to a withdrawal from social activities and a diminished capacity to perform daily tasks.
