Sense of Smell Linked to Speed of Brain Loss and Cognitive Decline, Alzheimer’s May Increase DNA Variants in Brain Neurons

Check out the latest in aging advances, research, and events from NIA:

• Alzheimer’s may increase DNA variants in brain neurons — An NIA-funded study found that neurons in the brains of people with Alzheimer’s disease accumulate more DNA changes, and these changes differ from those found in people without the disease.
• Sense of smell linked to speed of brain loss and cognitive decline — NIA-led research found associations between the ability to identify smells with rates of brain volume loss, cognitive decline, and dementia.
