Alzheimer's disease primarily affects which aspects of functioning?

The correct answer highlights the core cognitive functions that Alzheimer’s disease predominantly disrupts, which include memory, language, and physical functioning. Alzheimer's is primarily classified as a neurodegenerative disorder that affects brain areas responsible for memory formation and recall. As the disease progresses, individuals often experience significant memory loss, including difficulty recalling recent events or familiar faces.

Language abilities also diminish, leading to difficulties in finding the right words, forming coherent sentences, or following conversations. This aspect can dramatically affect communication skills, making it challenging for individuals to engage meaningfully in discussions.

Additionally, physical functioning can decline as the disease advances, affecting coordination and mobility. While Alzheimer's symptoms can lead to difficulties in social interactions and emotional regulation, the primary impairments directly tied to the disease itself notably encompass memory, language, and aspects of physical functioning, making this response the most accurate representation of the disease's impact.
