Drinking coffee may help in certain mental health disorders. Both low and high levels of coffee consumption have been shown to substantially reduce depression rates by approximately 30%. In a separate study, the risk for suicide decreased by around 45% in those who drank two to three and four or more cups of coffee per day compared with those who drank one or fewer cups per week.

Although coffee consumption has consistently been shown to reduce the risk for Parkinson's disease, decaffeinated coffee has not shown similar protective value. Coffee drinkers with mild cognitive impairment were also shown to have an associated decreased risk for or delayed onset of dementia. However, a recent large-scale study found that drinking six or more cups of coffee per day is associated with smaller brain volume and a 53% increased risk for dementia.
