Final answer:
ADL impairments involve difficulty with tasks like cooking or cleaning, while IADL impairments involve trouble with self-care activities like standing or dressing. These impairments can be seen in moderate and severe Alzheimer's disease (AD).
Step-by-step explanation:
In the context of Alzheimer's disease (AD), difficulties with tasks such as cooking or cleaning are referred to as Activities of Daily Living (ADL) impairments. These impairments can be seen in moderate AD, where patients may have trouble carrying out daily activities like dressing. On the other hand, self-care activities such as standing or dressing are referred to as Instrumental Activities of Daily Living (IADL) impairments. These impairments may be observed in severe AD.
