Spending time with friends may be an important factor in the fight against mild cognitive impairment. In a study with more than 10,000 people followed for over 28 years, participants’ social contact was assessed six times using a simple questionnaire about frequency of friend and relative visitation. While no improvement was found with interactions among family members, researchers found a lower dementia risk in those who fraternize with friends on a regular basis.
