Researchers identified neurons in an ancient brain region that function as a focus filter, enabling selective attention to relevant stimuli. Temporarily disabling these neurons in mice produced ADHD-like distractibility symptoms, which normalized upon reactivation, suggesting a biological mechanism underlying attention regulation.
This retrospective cohort study analyzed 5,595 Japanese patients newly diagnosed with bipolar disorder to examine whether a prior depression diagnosis and its duration affected psychiatric and all-cause hospitalization rates and mortality. Patients with prior depression history showed slightly lower all-cause hospitalization risk (HR=0.87), with duration of preceding depression (≥1 year vs <1 year) not significantly altering psychiatric hospitalization outcomes.
Researchers identified an evolutionarily conserved circuit of inhibitory neurons in the brainstem that regulates selective spatial attention. This discovery may enhance understanding of attention mechanisms relevant to conditions like ADHD.
This academic paper traces the historical origins of the term 'autism' coined by Eugen Bleuler in 1910 to describe schizophrenia, and how the concept was later borrowed to describe autism spectrum disorder, leading to diagnostic confusion. The authors argue that autistic features in schizophrenia differ fundamentally from autism spectrum disorder—rooted in self-disorder rather than developmental autism—and propose this distinction is crucial for accurate differential diagnosis and appropriate treatment.
This literature review examines the association between bipolar disorder and Parkinson's disease, focusing on their shared dopaminergic dysfunction in nigrostriatal and mesolimbic pathways. Recent analyses and meta-analyses show increased risk of developing Parkinson's disease in bipolar disorder patients, though differentiating idiopathic from medication-induced parkinsonism requires careful evaluation including DAT scans.
