There are two answers to the question of why we don’t yet fully understand Alzheimer’s. The simple answer is that the brain is remarkably complex, it’s the primary organ for cognition thus making investigation into the organ risky, and also research into the brain and mind are, relatively speaking, nascent fields. The more nuanced answer provides context into those stipulations. Alzheimer’s — a neurodegenerative form of dementia — is a condition with a constellation of symptoms that result from damage to the brain so there is nothing to be said about Alzheimer’s without first discussing what some call “the most complicated object in the universe,” the brain.
Scientists worldwide are conducting studies to learn more about what causes dementia, how to prevent it, and how to slow the onset of the disease.
Dementia and Alzheimer’s disease both affect cognitive and memory functions of the brain. Alzheimer’s disease is a specific type of dementia.
