What is a defining feature of Alzheimer’s disease?

A defining feature of Alzheimer’s disease is the gradual deterioration of cognitive functions. This progressive decline affects various cognitive abilities, including memory, reasoning, and problem-solving skills, ultimately interfering with daily life and independence. Unlike temporary conditions or reversible cognitive issues, Alzheimer's is a chronic and irreversible condition that worsens over time. The gradual nature of cognitive decline in Alzheimer’s can lead to significant impairment in social and occupational functioning, as a person may struggle with tasks that were previously routine or easily managed. Understanding this feature is crucial for recognizing Alzheimer's and differentiating it from other cognitive disorders that may not present such a relentless decline.
