Key Takeaways and Next Steps

Dementia is a Collection of Symptoms
Dementia refers to symptoms like memory and thinking decline severe enough to affect daily life.
It can result from various causes, both reversible (e.g., hypothyroidism, depression) and irreversible (e.g., Alzheimer’s, Parkinson’s-related dementia).
Alzheimer’s is a Cause of Dementia
Alzheimer’s disease accounts for about 80% of all dementia cases, making it the most common cause.
It is a progressive, neurodegenerative disease and is not reversible.
Other Forms of Dementia
Include vascular dementia (often from strokes), dementia associated with Parkinson’s, frontotemporal dementia, and others like CTE linked to head trauma.
Some forms, like polypharmacy-induced dementia, may improve with medical intervention.
Dementia Can Have Multiple Causes
It is possible to have more than one contributing factor, such as Alzheimer’s combined with vascular dementia.
Clear Answers, Better Understanding
Understanding these distinctions helps clarify conversations about symptoms, diagnoses, and potential treatments.
