Dementia & Alzheimer’s disease
A common disorder among the elderly, dementia can affect as many as 30% of those aged over 85 years. However, two Dutch studies, involving several thousand subjects, have reported that regular consumption of fish seems to protect against age-related brain impairment and dementia.
Across the Atlantic, a USA study found a link between low fish consumption and Alzheimer’s disease. As yet, no supplementation studies have been carried out in the elderly, but the idea that fish is helpful for maintaining brainpower throughout life is certainly gaining approval among scientists.
