Dementia and Alzheimer's are described as:

Dementia and Alzheimer's are classified as organic, progressive mental disorders because they involve degenerative changes in the brain that lead to cognitive decline, memory loss, and ultimately a decrease in daily functioning. These conditions are rooted in physical changes within the brain's structure and chemistry, which distinguishes them from non-organic mental health conditions that may be influenced by psychological factors without the same degree of biological deterioration.

The term "progressive" signifies that these disorders worsen over time, leading to increased impairment. In the case of Alzheimer's disease, it specifically represents a form of dementia characterized by a gradual decline in memory and cognitive abilities due to the accumulation of abnormal proteins in the brain.

This classification is important when discussing treatment options and care strategies for affected individuals, as it underscores the need for medical intervention and ongoing support, rather than viewing these conditions as normal aging processes or temporary issues that can be resolved.
