Cross-sectional studyMechanisms
Who was studiedPeople across the lifespan and clinical conditions
What changedBrain activity complexity was higher with healthy aging but lower with mild cognitive impairment and Alzheimer's disease
The catchThe abstract omitted participant numbers and ages, limiting assessment of sample size and age differences
