Prenatal Depression Alters Child’s Brain Connectivity and Affects Behavior

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.

Body Weight Has Surprising and Alarming Impact on Brain Function

Obesity and higher body mass are linked to decreased cerebral blood flow. Lower cerebral blood flow is associated with an increased risk of Alzheimer's disease and a range of psychiatric disorders.

Greater Excitability in Social Brain Regions of Autistic Men Compared to Women

Males with autism have atypically enhanced excitation in the medial prefrontal cortex (mPFC). This area of the brain is associated with social cognition and self-reflection. Autistic women showed a more intact mPFC response, which was associated with a better ability to camouflage social difficulties in real-world settings.

‘Little Brain’ or Cerebellum Not So Little After All

High resolution imaging reveals the human cerebellum is 80% of the area of the cortex. The findings indicate this area of the brain likely grew larger as human behavior and cognition evolved.

Mental Fatigue of Multiple Sclerosis Linked to Inefficient Recruitment of Neural Resources

Those with MS allocate neural resources less effectively when faced with increased cognitive task demands, and this likely results in the increased mental fatigue those with the neurodegenerative disorder experience.

Further Evidence World Trade Center Responders Are at Risk for Dementia

First responders at the World Trade Center have reduced cortical gray matter thickness, which was consistent with neurodegenerative conditions and evidence their brain age is, on average, ten years older than those of similar ages in the general population.

Adults With Alzheimer’s Risk Factors Show Subtle Alterations in Brain Networks Despite Normal Cognition

APOEe4, a gene associated with Alzheimer's disease risk, doesn't appear to directly affect memory performance or brain activity in older adults without cognitive impairment. However, the gene does seem to influence brain regions and systems that older at-risk adults activate to support successful memory recall.
