What condition is characterized by thought or social skills affecting daily functions?

Dementia is a condition that notably affects cognitive functions such as memory, reasoning, and social skills, which can significantly impact a person's daily life. Individuals with dementia often experience difficulties with communication, understanding social cues, and performing everyday activities. These impairments can lead to challenges in maintaining relationships and managing personal care, ultimately affecting their quality of life.

While Alzheimer's disease is a type of dementia and is characterized by similar cognitive decline, the term "dementia" encompasses a broader range of conditions that cause cognitive impairment. Congestive heart failure and stroke, on the other hand, primarily relate to heart and brain functions, respectively, and while they may lead to cognitive issues in some cases, they are not defined by social skills or thought processes affecting daily functions in the primary sense. Therefore, the most accurate choice in this context is dementia, as it directly aligns with the description of how thought and social skills can impact daily living.
