Symptoms of autism may be seen in babies as young as 12 months.

Early Detection Helps Reduce Effects of Dyslexia

It's now possible to detect dyslexia in children too young to read.

Early Exposure to Toxic Substances Damages Brain Architecture

A fMRI study by Sheryl Rimrodt and Laurie Cutting and their team at the Kennedy Krieger Institute found that children with reading difficulties do not have the flexibility in their reading comprehension that typically developing readers do.

Screening for Childhood Disorders: Is There a Downside?

The American Academy of Pediatrics recently recommended that all infants be screened for autism spectrum disorders (ASD). It's a necessary step in identifying and treating the disorder early — but there are questions about the potential for overdiagnosis with widespread screening.

Serotonin and SIDS

The article cites a study which examines how serotonin levels affected anxiety-related behavior in mice when surprised.  Researchers at the European Molecular Biology Laboratory in Monterotondo, Italy, found that nearly three quarters of mice died before tuning four months old due to sudden drop in heart rate.  They view that it occurs when serotonin activity cannot ramp up.  The findings showed that sudden infant death syndrome (SIDS) can be prevented by regulating abnormal serotonin feedback.
