Live well, think well: Research shows healthy habits tied to brain health

In middle-aged people, having risk factors like blood pressure, blood sugar and cholesterol that are not well-controlled combined with not following certain healthy habits including exercise, diet and sleep, are linked to a higher risk of stroke, dementia or depression later in life, according to a new study. These results do not prove that not having healthy habits increases the risk of these conditions, they only show an association.
