New Research Could Explain Why Autism Is More Common In Boys Than Girls

INTRO: Autism spectrum disorder (ASD) is thought to occur roughly four times as frequently in boys as it does in girls, and a new study in the journal Brain may have finally hit upon the reason for this disparity. After analyzing the genetic changes underlying the condition, the researchers found evidence for a “female protective effect”, whereby a significantly greater number of genetic mutations is required for the appearance of autism-like symptoms in girls versus boys.

Moreover, the results suggest that the genes involved tend to relate to different brain regions between the two – meaning that the neural mechanism that drives ASD in girls is in fact distinct from that seen in boys. This finding significantly enhances our understanding of the condition and suggests that any conclusions drawn from previous studies into autism in boys may not hold true for girls... (MORE)

Have introverts really fared better in lockdown?

EXCERPTS: Since the onset of the pandemic, everyone from newspaper columnists to Twitter users has advanced the idea that extroverts and introverts are handling the crisis differently. Many claim that introverts adapt to social distancing and isolation better than extroverts, with some even suggesting that introverts are practically “loving” the crisis, as it offers them a rare chance to play to their strengths.

According to personality theories, extroversion-introversion constitutes one of the fundamental psychological axes along which people differ. Extroverts typically exhibit higher levels of energy and sociability compared to introverts, enjoying a boost in mood after social interactions. Introverts do not tend to experience such benefits.

It therefore seems intuitive that introverts will fare better than extroverts during periods of lockdown isolation. Some anecdotal evidence supports this contention, but scientific evidence is now stacking up to dismiss the idea that introverts love lockdowns. In any case, it’s worth bearing in mind how complex and multifaceted our personalities are – with many other traits determining how we’ve fared during the pandemic.

[...] recent studies have found that introversion was predictive of more severe loneliness, anxiety and depression after the circumstantial changes brought about by the pandemic. Extroversion, meanwhile, was correlated with lower levels of anxiety and a lower likelihood of experiencing mental health issues during lockdown.

These results were further supported by a recent longitudinal study that followed 484 US college students through their 2020 spring term. As the pandemic progressed, introverts experienced increases in stress, while more extrovert students reported slight decreases in stress... (MORE - details)
