Ecstasy use linked to lasting memory deficits despite abstinence

A meta-analysis of 14 studies finds recreational MDMA users perform worse on memory tests than non-users, with verbal memory most affected, and these deficits persisting even after six months to years of abstinence. Current users do not differ much from abstinent users, suggesting potential long-lasting effects. However, evidence quality is generally low due to cross-sectional designs and confounding polydrug use, underscoring the need for longitudinal studies and objective exposure measures to clarify reversibility and public health risk.

The Brain Vitamin Most People Are Missing

Vitamin B-12 is essential for brain health, supporting myelin formation, DNA synthesis, and neurotransmitter production while helping to reduce homocysteine. A deficiency can cause fatigue, memory issues, concentration problems, balance troubles, and mood changes, with higher risk in older adults and those who are vegetarian/vegan or have absorption issues. Testing B-12 (and related markers) and early treatment with diet or supplements can reverse cognitive symptoms; untreated deficiency can lead to lasting brain decline or dementia.

B-12 and the Brain: Why This Deficient Nutrient Is Key to Memory and Mood

B-12 and the Brain: Why This Deficient Nutrient Is Key to Memory and Mood

Vitamin B-12 is crucial for brain health, helping build myelin, support DNA synthesis, and produce neurotransmitters; when levels drop, memory, focus and mood can suffer, with older adults and vegetarians at higher risk. Deficiency is common and can cause fatigue, numbness, balance issues, and cognitive decline. It’s diagnosed by blood tests (B-12, plus homocysteine and methylmalonic acid as needed). Good dietary sources include animal products and fortified foods; supplementation is typically oral, with injections for more severe cases. Early treatment can reverse memory problems and brain fog, while prolonged deficiency can lead to irreversible issues.

Active Sitting May Protect Brain Health, Study Finds

Active Sitting May Protect Brain Health, Study Finds

A review of 85 studies shows that mentally engaging sedentary activities (like reading or using a computer) are linked to better cognitive health, while passive sedentary behavior (like watching TV) is associated with greater dementia risk; the findings argue for differentiating sitting types and encouraging brief, brain-stimulating activity during sedentary time.
