Targeting Glucose May Spark Neurogenesis

Neural stem cells, which create new neurons in the brain, become less active with age due to elevated glucose levels. Researchers found that by knocking out the glucose transporter gene GLUT4 in older mice, they could significantly increase the production of new neurons.

Blocking a Brain Pathway Reverses Memory Loss in Alzheimer’s

Blocking the kynurenine pathway, a regulator of brain metabolism, can restore cognitive function in lab mice with Alzheimer’s disease. The pathway is overactivated in Alzheimer’s, disrupting glucose metabolism and starving neurons of energy. By inhibiting this pathway, researchers improved memory and brain plasticity in mice, offering hope for new treatments in humans. IDO1 inhibitors, currently in cancer trials, could be repurposed for Alzheimer’s treatment.

Brain Plasticity’s Dark Side: New Insights into Addiction Mechanisms

Researchers discovered that adaptive myelination, a form of brain plasticity, contributes to drug addiction. A single morphine dose in mice triggered myelination in reward-related brain circuits, reinforcing drug-seeking behavior. Blocking this myelination prevented addiction, highlighting potential new treatment strategies.

Night Owls Beware: Late Bedtimes Harm Mental Health

Staying up late harms mental health regardless of one's natural sleep preference. Surveying nearly 75,000 adults, researchers discovered that both morning and night types who stayed up late had higher rates of mental disorders. Surprisingly, aligning with one's chronotype didn't matter—early bedtimes benefited everyone. The study suggests lights out by 1 a.m. for better mental health.

Keto Diet May Improve Mental Health Symptoms

A new pilot study presents a compelling case for the ketogenic diet as a dual-action treatment for individuals with serious mental illnesses like schizophrenia and bipolar disorder, who often suffer metabolic side effects from their medication. The research shows how adopting a ketogenic diet not only mitigates these metabolic issues but also significantly improves psychiatric conditions.

Emotion vs. Reason: Rethinking Decision-Making

Researchers challenge the notion that rational thinking is the only path to good decision-making. Highlighting the limited role of rationality in our choices, the researchers emphasize the profound influence of emotions, as demonstrated in his wine tasting study where perceived value affected enjoyment.

Ketamine’s Effects Diverge by Sex

Ketamine's effects on depression and pain, and its interaction with opioid pathways, significantly differ between sexes. In a detailed rat study, the team found that blocking opioid receptors nullified ketamine's impact only in males, suggesting a complex interplay between ketamine, opioid systems, and sex hormones.

Psychoactive Ibogaine and Magnesium Show Promise for PTSD

Ibogaine, a plant-based psychoactive drug combined with magnesium, effectively reduces PTSD, anxiety, and depression in veterans with traumatic brain injuries (TBI). The study, involving 30 U.S. special forces veterans, showed significant and lasting improvements in mental health and functioning post-treatment.

Electrical Stimulation Enhances Hypnotizability

Researchers have found that targeted electrical stimulation of the brain can temporarily increase a person's hypnotizability, potentially allowing more individuals to benefit from hypnosis-based therapies for pain relief and other conditions. In a study involving participants with fibromyalgia, electrical stimulation delivered to the left dorsolateral prefrontal cortex boosted hypnotizability for about an hour.
