Moving Beyond Dopamine to Treat Schizophrenia
Summary: Schizophrenia treatment has been dominated by dopamine-targeting drugs for decades, but these often fail to address the debilitating cognitive and negative symptoms of the disorder. A comprehensive review synthesizes…
Thrill Fatigue: How Dopamine Devalues Repeated Rewards
Summary: New research shows that the same dopamine receptor mechanism responsible for drug addiction also governs the natural decline in motivation when we repeat rewarding behaviors. By studying male fruit…
More Than Serotonin: How Psychedelics Engage the Whole Brain
Summary: Classical psychedelics like LSD, psilocybin, and mescaline are known for activating the 5-HT2A serotonin receptor, but a new study reveals their effects go far beyond. Researchers profiled 41 psychedelics…
Low Sodium Linked to Anxiety Through Brain Chemistry Disruption
Summary: Chronic hyponatremia—long viewed as symptomless—is now shown to disrupt brain chemistry and cause anxiety-like behaviors, according to a new study in mice. Researchers found that prolonged low sodium levels…
Shared Genetic Signatures Found Across Psychiatric Disorders
Summary: Researchers have uncovered shared biological mechanisms across major psychiatric disorders by analyzing postmortem brain samples from the dorsolateral prefrontal cortex. Instead of looking at gene expression broadly, they zoomed…
Vitamin B1 Derivative Sparks Dopamine, Boosts Wakefulness
Summary: Thiamine derivatives, once developed to treat nutrient deficiencies, are now being explored for their potential effects on brain function and energy. A new study shows that TTFD, a thiamine…
Potential Depression Risk Linked to Ozempic-Like Drugs
Summary: A new international study reveals a possible connection between GLP1 receptor agonists—used in drugs like Ozempic—and increased risk of depression and suicidal ideation, especially in people with low dopamine…
Dopamine Clock May Drive Bipolar Mood Swings
Summary: New research suggests that mood swings in bipolar disorder are regulated by two clocks: the body’s 24-hour circadian rhythm and a dopamine-based clock that influences alertness. When these clocks…
