What does dementia refer to?

Dementia refers to an irreversible deterioration of intellectual ability, which includes memory loss, problem-solving difficulties, language impairment, and changes in reasoning abilities. It is a broad term used to describe various conditions that cause cognitive decline, affecting daily functioning and independence. Unlike temporary memory loss, which may be reversible or due to stress or fatigue, dementia is characterized by a progressive decline that worsens over time and is most commonly associated with diseases like Alzheimer's.

The condition is not related to developmental delays in children, which involve different aspects of growth and learning. Furthermore, psychological trauma from past experiences can lead to mental health issues but does not define the cognitive deterioration seen in dementia. Understanding dementia as a specific category of cognitive impairment helps in recognizing its impact on individuals and their families.
