<p>Psychology literature has shown that curiosity tends to decline with age. Psychologists shows one type of curiosity can increase well into old age, contradicting prior research. Older adults who maintain curiosity and want to learn new things relevant to their interests may be able to offset or even prevent Alzheimer's disease. Conversely, those who show muted curiosity and disinterest may be at risk for dementia.</p>
