Written by Joyce Smith, BS. This study suggests that a minimum dose of two grams per day of docosahexaenoic acid (DHA) is required to ensure adequate delivery to the brain, particularly for those individuals who carry the APOE4 allele. Many studies have extolled the...
Air Pollution in London is Associated with Increased Risk of Dementia
Written by Joyce Smith, BS. Study finds that older residents of London living in areas with higher air pollution were more likely to be diagnosed with dementia in subsequent years compared to those living in areas of lower air pollution. Dementia, including both...
Migraines are Associated with Dementia in Women
Written by Joyce Smith, BS. Study finds that migraine history is a significant risk factor for Alzheimer disease (AD) and all‐cause dementia, but not vascular dementia in a population of older independently-living adults. Dementia is a neurological age-related disease...
Constant Worry may Negatively Impact Brain Health – Informed Opinion
Written by Patrick Massey, MD, PhD. A recent medical study concluded that people who repetitively have negative thoughts are at an increased risk of developing Alzheimer's disease later in life. Is it possible to reduce the risk of Alzheimer's disease by changing the...
Long-term Dietary Flavonoid Intake May Reduce Alzheimer’s Disease and Related Dementias
Written by Joyce Smith, BS. Twenty years of consuming small amounts of flavonoid rich foods such as apples, berries and tea doubled and even quadrupled the risk of developing Alzheimer’s disease (AD) and Alzheimer’s disease related dementias (ADRD) compared to...
Prophylactic Beta-Hydroxybutyrate for Alzheimer’s Disease and Atherosclerosis
Written by Angeline A. De Leon, Staff Writer. This study explores the anti-inflammatory capability of beta-hydroxybutyrate (β-OHB) and the mechanism by which it protects against Alzheimer’s disease (AD) and atherosclerosis. As the number of annual cases of dementia...
Sleep-Disordered Breathing Associated with Alzheimer Disease in Asymptomatic Elderly
Written by Joyce Smith, BS. Study found that cognitively unimpaired older adults with sleep-disordered breathing (SDB) had SDB-associated brain changes, including greater amyloid deposition and neuronal activity in brain regions associated with Alzheimer disease. SDB,...
Reduced Non-Rapid Eye Movement Sleep is Associated with Early Alzheimer’s Disease
Written by Joyce Smith, BS. Slow wave activity (SWA) during non-rapid eye movement (NREM) sleep decreases with disease progression in patients with Alzheimer’s disease. The early stages of Alzheimer’s disease (AD) pathogenesis are characterized by an aggregation of...
Lower Plasma Amyloid-Beta Levels Associated with Risk of Dementia
Written by Angeline A. De Leon, Staff Writer. This study provides evidence that lower plasma Aβ levels, specifically Aβ1–38 and Aβ1–42, are associated with an increased risk of dementia, specifically Alzheimer’s disease. Dementia is associated with the accumulation of...
The Age of Mild Traumatic Brain Injury Affects Brain Health
Written by Joyce Smith, BS. This study has important implications for young athletes at risk of mTBI and for retired athletes with a history of earlier age concussions. Mounting evidence suggests that mild traumatic brain injury (mTBI), or concussion, is associated...
