| | | The Most Common Symptom of Dementia
What do you think is the most common symptom of dementia? A lot of people might guess memory loss, but the answer is actually apathy. Apathy is neither widely discussed nor studied—perhaps because it doesn’t seem as disruptive as other symptoms, though it has devastating effects on quality of life. A new study aims to change that by understanding the prevalence of apathy in dementia. Learn more. |

Awe Is Awesome for You

Conscience: The Origins of Moral Intuition (2019)
By Patricia Churchland
In Conscience, neurophilosopher Patricia Churchland makes the case that morality is rooted in biology; specifically, in how the brain has evolved to support and reinforce useful norms of behavior that help sustain a successful community. Discussing neurochemicals and brain regions, and everything from political views to prairie voles, Churchland sheds light on how our values are shaped in our brains. It’s a fascinating—though not uncontroversial—perspective. Learn more or buy on Amazon. |
