Which statement describes potentially reversible dementias?

• A. Symptoms of cognitive decline that can be caused by treatable conditions and may improve or resolve with treatment
• B. Irreversible brain damage
• C. Rapid progression with no treatment effect
• D. Dementia due to advanced age

Answer: (A)

Some cognitive decline in older adults is due to conditions that are treatable, and when those conditions are addressed, cognition can improve or even return toward normal. That’s what potentially reversible dementias describe. Dementia is often linked to progressive neurodegenerative or vascular damage and may be irreversible, but there are treatable factors—such as thyroid dysfunction, vitamin B12 deficiency, metabolic or electrolyte problems, medication effects, infections, depression (pseudodementia), normal pressure hydrocephalus, subdural hematoma, or alcohol-related/c malnutrition—where correcting the underlying issue can lead to improvement. The key point is recognizing that some cognitive decline with dementia-like features is not fixed and can improve with appropriate treatment.
