Final answer:
Disruptive memory loss, confusion about time or place, and difficulty planning or executing tasks are early manifestations of Alzheimer's disease.
Step-by-step explanation:
One early manifestation of Alzheimer's disease is disruptive memory loss. This can include forgetting important information, such as recent events or important dates. For example, a person with Alzheimer's disease may struggle to remember appointments, names of family members, or where they put their belongings.
In addition to memory loss, confusion about time or place can also be an early symptom of Alzheimer's disease. This can involve difficulty keeping track of the current date or getting disoriented in familiar surroundings.
Difficulty planning or executing tasks is another behavior that can be observed in the early stages of Alzheimer's disease. This can manifest as struggling to follow a recipe, complete a familiar task, or organize daily activities.
