Obesity is associated with reduce cortical thickness in bipolar disorders
Sean R. McWhinney et al reported in Psychological Medicine (2023) that obesity was associated with reduced cortical thickness (but not surface area) in most areas of the brain in 2832 participants.
Editors Note: Patients and clinicians should try to prevent and reduce weight gain using the best tolerated medications from the outset and helping with weight loss by various measures. These can include the anticonvulsants topiramated and zonisamine, the combination of bupropion and naltrexone, and the use of new anti-diabetic drugs such as Jardiance and Farxiga that have weight loss (greater than with metformin) as a side effect. Prescribing a good diet and regular exercise is also indicated. Reducing obesity will likely make you live longer and maybe could even make you smarter.
Single-dose psilocybin-assisted therapy in major depressive disorder: a placebo-controlled, double-blind, randomized clinical trial
von Rotz et al reported in eClinical Medicine (the Lancet) that a single dose of psilocybin produced a huge AD (anti-depressant) effect compared to placebo. A dose of 0.215mg Kg (about 15mg for a 70kg person) had a rapid onset AD effect that persisted for at least 14 days. Music was played and in a living room like environment. Psychological support was provided on 3 visits pretreatment and on days 8 and 14 for a total of 14 hours
Inflammatory marker CRP predicts worse course of adolescent bipolar disorder
Sudhir Karthikeyan in Ben Goldstein’s lab in Toronto reported in Brain Behav Immun (2022) that in 79 adolescents the inflammatory marker CRP (C-Reactive Protein) was higher and the anti-inflammatory cytokine Il-10 was lower during the most ill periods compared to normal volunteers. “Moreover, higher CRP levels (p = 0.009) at intake predicted greater time to recovery from the index symptomatic episode.” They concluded that: “In the first repeated-measures study on this topic in adolescents with BD, we found evidence that CRP, an inexpensive and ubiquitous blood test, may be useful in predicting the prospective course of BD symptoms. “
