Hypertension Linked to Impaired Cognition & Gait in Older Adults (2024 Study)

Hypertension in older adults leads to poorer cognitive and walking performance due to the need for more brain resources to manage dual tasks. Highlights: Older adults with hypertension show higher brain activation in motor and sensory areas when performing dual cognitive-walking tasks compared to healthy peers. Hypertensive individuals have worse cognitive performance on single cognitive …

Age-Related Brain Volume Changes in Men & Women (2024 MRI Study)

Normal aging leads to a decrease in brain volume, with gray and white matter shrinking and cerebrospinal fluid increasing, as measured by synthetic MRI. Highlights: Study Sample: 300 healthy adults (141 males, median age 48; 159 females, median age 50) were analyzed using synthetic MRI. Brain Volume Trends: Brain parenchymal volume (nBPV) decreases steadily with …

Cocaine Destroys Gray Matter & Accelerates Brain Aging

Cocaine use can lead to significant structural changes and accelerated aging of the brain, according to a new study. Key findings include: Cocaine users showed widespread gray matter loss in areas involved in emotions, language, cognition and decision-making. Cocaine users had “older” looking brains, with brain-predicted age 2.5 years higher than their real age. Brain …

High Rates of Pineal Gland Calcification & Possible Health Effects

Pineal gland calcification, the buildup of calcium deposits in the pineal gland, is surprisingly common, affecting over 60% of the population according to a new meta-analysis. This concerning condition can disrupt proper pineal gland functioning and melatonin secretion, potentially contributing to an array of health issues. Key Facts: The pineal gland regulates circadian rhythms through …

Medium Chain Triglycerides Boost Cognition & Memory in Healthy Older Adults

A new systematic review published in BMC Geriatrics suggests that supplementing with medium-chain triglycerides (MCTs) may provide cognitive benefits for older adults without dementia. MCTs are a type of fatty acid found in foods like coconut oil and palm kernel oil that may help provide the brain with an alternative energy source. Key Facts: MCT …

Medium Chain Triglycerides (MCTs) for Alzheimers Disease: Benefits for APOE e4(-) Patients?

Alzheimer’s disease (AD) is a growing global health concern, but current drug therapies have shown limited effectiveness for symptom management and disease modification. Medium chain triglycerides (MCTs) have emerged as a potential nutritional therapy, but evidence remains inconclusive. Key Facts: MCTs may provide an alternative brain fuel source and reduce AD biomarkers like amyloid-beta. Small …

Dopamine in Parkinsons Disease: Insights & Future Therapies

Parkinson’s disease (PD) is a neurodegenerative disorder characterized by the loss of dopamine-producing neurons. Dopamine plays an important role in PD development. Here are some key facts: Dopamine is a chemical messenger in the brain involved in movement, motivation, and mood. Loss of dopamine-producing neurons causes the motor symptoms of PD like tremors, rigidity, and …

Type 2 Diabetes & Brain Effects in Native Americans: What A New Study Suggests

A new study looked at how having diabetes may impact brain health in Native Americans. The researchers found that the longer someone had diabetes, the more it affected their brain. But other health issues like obesity did not appear to impact the brain as much. Key facts: The study involved 51 Native Americans with type …
