Early maternal anemia tied to intellectual disability, ADHD and autism

Children born to mothers diagnosed with anemia before the 31st week of pregnancy were at a higher risk of developing ADHD, ASD, and other intellectual disabilities than children born to mothers diagnosed with anemia during the final weeks of pregnancy. The risk of being diagnosed with autism was 4.9% higher for those born to mothers who experienced early pregnancy anemia. For ADHD, those born to anemic mothers had a 9.3% higher risk than those born to mothers who developed the condition during late pregnancy.

Increased risk of psychiatric disorders in children with inflammatory bowel disease

Children with inflammatory bowel disease (IBD) are at increased risk of being diagnosed with a mental health problem. The risk of being diagnosed with a psychiatric condition is 1.6 times higher for those with IBD than the general population. IBD is associated with an increased risk of eating disorders, anxiety, depression, personality disorders, and ASD diagnosis. Researchers report there is also an increased risk of suicidal thoughts when the child reaches adulthood. The risk of being diagnosed with a psychiatric disorder was highest during the first year of IBD diagnosis, especially in children diagnosed with the condition before the age of 6.

Adult-onset inflammatory bowel disease linked to higher mortality

Diagnosis of inflammatory bowel diseases like Crohn's disease and ulcerative colitis during adulthood has been linked to a 50% higher mortality rate and shorter life expectancy in those over 50. The increased risk of death remained after the introduction of therapies aimed at treating the conditions but decreased over time.

Mechanism Controlling Multiple Sclerosis Risk Identified

Researchers have identified a new mechanism of a risk gene for multiple sclerosis that triggers the disease via epigentic regulation. The study reports a protective genetic variant can reduce the risk of multiple sclerosis through the same mechanism.
