Which statement is a true characteristic of dementia?

Dementia is characterized by a range of cognitive decline and does not manifest uniformly across all individuals. Each person's experience with dementia can differ based on factors such as the specific type of dementia they have, their health status, personality, and individual history. Symptoms may include changes in memory, thinking, behavior, and daily functioning, and these can fluctuate in severity from one person to another and even change over time within the same individual. This variability is a key feature that distinguishes dementia from conditions like normal aging, which generally does not present such broad cognitive deficits or drastic changes in behavior. Understanding this variability is crucial for caregivers and healthcare providers as they develop personalized care strategies and communication approaches tailored to each individual's unique experience with dementia.
