- The World Health Organization has issued guidelines to prevent cognitive decline and dementia that stress healthy living and management of diabetes, hypertension, weight, and dyslipidemia.
Why this matters
- Dementia affects about 50 million people worldwide, and is projected to affect 152 million by 2050.
- Physical activity and cognitive training could reduce the risk for cognitive decline in adults with normal cognition or mild cognitive impairment.
- Programs to promote cessation of smoking and hazardous or harmful drinking should be offered.
- A Mediterranean-like diet could reduce cognitive impairment.
- Vitamins B and E, polyunsaturated fatty acids, and multicomplex supplementation are not to be recommended to protect against cognitive decline.
- Management of hypertension, diabetes, dyslipidemia, and midlife overweight or obesity could prevent cognitive decline and/or dementia.
- There is insufficient evidence to recommend interventions for depression or hearing loss for prevention of cognitive decline and/or dementia.
