Two recent studies have further underscored my long held belief that many diseases, including those of the brain, actually begin early in life, perhaps even in childhood. The idea that a disease is proactive demands that we are adopt an equally proactive healthy lifestyle.
One study found that high cholesterol levels in the 40s may raise the chance of developing Alzheimer’s Disease (AD) decades later. The findings presented at the American Academy of Neurology in Chicago studied over 9,000 people in California and found that those with high cholesterol levels between the ages of 40 and 45 were about 50 percent more likely than those with low cholesterol to later develop AD.
Another study from Sweden found those with diabetes in midlife are 1.5 times more likely to develop AD later in life. This study followed over 2000 men for 32 years and while other risk factors for AD were found, the most significant was low insulin secretion in midlife.
These studies and others indicate the lifelong development of AD and that we really should not consider this disease a late life disorder. The studies also underscore our need to develop interventions much earlier in life and to adopt a brain healthy lifestyle (e.g. brain fitness) regardless. Such a lifestyle should be a national priority and begin in early childhood if not earlier.
