Cannabidiol (CBD) increases cerebral blood flow to areas of the brain associated with memory processing, specifically the hippocampus. The findings identify a potential mechanism for the use of CBD to treat disorders associated with altered memory processing, including Alzheimer's disease, PTSD, and schizophrenia. Read More

Preschool-aged children on the autism spectrum were 2.7 times more likely to experience gastrointestinal problems, including pain, diarrhea, constipation, and vomiting than their typically developing peers. Almost 50% of those with ASD reported frequent GI symptoms, compared to 18% of those without the disorder. 30% of autistic children experienced multiple GI symptoms. Multiple GI problems were associated with sleep and attention problems, as well as self-harm, aggression, and repetitive behaviors in both children with ASD and those not on the autism spectrum.

Prenatal depression can have a significant influence on a child's brain development and behavior. Greater symptoms of prenatal depression were associated with weaker white matter connections between areas of the brain involved in emotional processing. The weakened white matter connectivity was linked to increased aggression and hyperactivity in male children. The change could lead to dysregulated emotional states in children and explain why children whose mothers experienced PND are more prone to developing depression later in life. Read More
