Early Autism Traits Show No Sex Differences in Toddlers

A large-scale study of over 2,500 toddlers found no significant clinical differences in autistic traits between males and females at the time of early diagnosis. Conducted over two decades, the study used comprehensive assessments across language, motor skills, cognitive traits, and social behaviors.

Protein Differences Between Sexes Aren’t All Genetic

An international study of 6,000 proteins across 56,000 people found that while protein levels differ significantly between males and females, most of these differences are not caused by genetics. Only about 100 proteins showed sex-specific genetic regulation, suggesting that environmental, hormonal, and lifestyle factors play a major role in shaping health outcomes.

Histamine Alters Dopamine Differently in Male and Female Brains

Sex differences in neurological disorders like Tourette syndrome, schizophrenia, and ADHD may stem from how histamine affects dopamine in the brain. A new mouse study reveals that histamine decreases dopamine in males but increases it in females, with the female response influenced by the estrous cycle.

Why Alcohol Hits Women Harder

Alcohol use among women has surged to match men’s rates, but women face far greater health risks even at lower consumption levels. A growing body of research is uncovering key neurobiological sex differences that influence why and how women drink, with stress being a more prominent motivator for women.

Study Confirms Early Brain Differences Between Sexes

A study analyzing over 500 newborns has confirmed that brain structure differences between male and female infants are present from birth. While male brains were larger on average, females had more grey matter in regions related to memory and emotion, whereas males had more white matter and grey matter in sensory and motor regions.

Females Sleep Less and Wake More: A New Study Reveals Why

Females experience less total sleep, more frequent awakenings, and reduced restorative sleep compared to males, according to a new study on mice. Researchers attribute these differences to biological factors rather than lifestyle, potentially linked to stress hormones and evolutionary roles.

Sex-Based Breakfast Choices May Boost Metabolism

A recent study using mathematical models suggests that breakfast choices may affect men’s and women’s metabolisms differently. Results indicate that men’s metabolisms respond better to carb-heavy breakfasts, while women’s bodies benefit more from higher-fat options like eggs or avocados, especially after fasting.

Men Show Higher Genetic Risk for Schizophrenia and Related Disorders

Researchers have found that schizophrenia shares genetic risk factors with bipolar disorder and major depression, with these vulnerabilities being more significant in men than in women. This new study analyzed over 3,000 individuals, finding that polygenic scores for various psychiatric disorders contribute differently to psychosis risk based on gender.

Sex Differences Found in Brain’s Reward Pathways

A new study reveals sex differences in how the brain's reward pathways function, specifically in the hippocampus and nucleus accumbens. Males and females use different molecular mechanisms to strengthen these connections, influencing responses to treatments for disorders like depression and substance abuse. The findings highlight the need for more gender-specific research to develop effective therapies. Researchers hope this will lead to improved patient outcomes.

Astrocyte Receptors Impact Memory Differently in Men and Women

Researchers discovered that astrocyte receptors impact cognitive function differently in male and female preclinical models. The study reveals that astrocytic signaling cannot be assumed to have the same cognitive effects across sexes. This finding suggests that therapies targeting astrocytic receptors may need to consider sex-specific impacts.
