Stem Cell Grafts Show Promise in Repairing Myelin in MS. New research demonstrates that neural stem cell grafts can restore myelin in damaged regions of the central nervous system, a breakthrough for progressive multiple sclerosis (MS). Scientists showed that induced neural

“Genetic and environmental influences on sleep quality, ability to settle, and crying duration in 2- and 5-month-old infants: A longitudinal twin study” by Charlotte Viktorsson et al. JCPP Advances.

Key Facts:. 1 - Crying and Genetics: Up to 70% of infant crying behavior by 5 months is explained by genetics. 2 - Environmental Influence: Night wakings and settling time are more shaped by environmental factors, especially in the first 2 months. 3 - Parental Impact: Parenting.

Why Your Baby Cries: It’s Largely Written in Their Genes. A peaceful nursery at night, showing a sleeping baby in a crib with soft light, while faint DNA strands and a clock are subtly overlaid to symbolize the genetic and environmental influences on infant sleep and crying.

Why Your Baby Cries: It’s Largely Written in Their Genes. A new twin study shows that how much an infant cries is primarily driven by genetics rather than parenting or environment. Researchers followed 1,000 twin pairs and found that at 2 months old, genetics explained about

“Impact of motor symptom asymmetry on non-motor outcomes in Parkinson’sdisease: a systematic review” by Julie Péron et al. npj Parkinson’s Disease.

Key Facts:. 1 - Right-Side Onset: Linked to higher risk of cognitive decline and dementia. 2 - Left-Side Onset: Associated with greater psychiatric symptoms like anxiety and depression. 3 - Personalized Therapy: Recognizing asymmetry could guide tailored treatment strategies.

Side of Parkinson’s Onset Shapes Cognitive and Emotional Decline. In Parkinson’s, the side where symptoms start matters: right-side onset predicts dementia risk, left-side onset predicts anxiety & depression. Personalized care plans tailored to asymmetry could improve outcomes.

Side of Parkinson’s Onset Shapes Cognitive and Emotional Decline. Parkinson’s disease often begins asymmetrically, with symptoms appearing first on one side of the body. Researchers have shown this initial side of onset also predicts how non-motor symptoms develop over time.

“Postnatal and juvenile fluoxetine treatment evokes sex-specific, opposing effects on mood-related behavior, gene expression, mitochondrial function, and dendritic architecture in the rat medial prefrontal cortex” by Vidita A. Vaidya et al. Biological Psychiatry.

Key Facts:. 1 - Developmental Window: Early-life fluoxetine worsens mood and brain metabolism, adolescent treatment improves them. 2 - Sex-Specific Effects: Negative outcomes from early treatment were observed in males only. 3 - Potential Rescue: Adult vitamin B3.

Timing of Prozac Treatment Shapes Lasting Mood, Brain Changes. Timing is everything: Fluoxetine in early life worsens long-term mood and brain function in males, but adolescent treatment improves it. Study highlights critical windows for antidepressant effects — and potential.

Timing of Prozac Treatment Shapes Lasting Mood, Brain Changes. Researchers have discovered that the effects of fluoxetine (Prozac) depend greatly on when during development it is administered. In male rodents, early postnatal treatment led to long-term increases in anxiety- and

“A meta-analytic review of child maltreatment and interoception” by Julia Ditzer et al. Nature Mental Health.

Key Facts:. 1 - Body Trust and Maltreatment: Emotional abuse and neglect are strongly associated with reduced trust in one’s own bodily signals. 2 - Mental Health Impact: Impaired body trust may contribute to anxiety, depression, eating disorders, and poor stress regulation. 3.

Emotional Neglect in Childhood Undermines Trust in One’s Own Body. Emotional abuse and neglect in childhood undermine body trust — a key factor in emotional health. New research highlights the invisible scars of maltreatment and the need to protect children’s emotional.

Emotional Neglect in Childhood Undermines Trust in One’s Own Body. A new study reveals how childhood emotional abuse and neglect shape a person’s relationship with their own body. The study analyzed 17 prior studies with 3,705 participants to examine links between child

“Striatal astrocytes modulate behavioral flexibility and whole-body metabolism in mice” by Enrica Montalban et al. Nature Communications.

Key Facts:. 1 - Astrocytes Matter: Obesity disrupts astrocyte function in the striatum, impairing brain and metabolic health. 2 - Cognition Restored: Rebalancing astrocyte calcium signaling improved learning in obese mice. 3 - Therapeutic Potential: Astrocytes emerge as targets.

Astrocytes in Obesity: Brain Cells That Control Metabolism & Cognition. Astrocytes take the spotlight: new research shows restoring their function in obesity improves both brain flexibility and metabolism, offering a promising therapeutic target.

Astrocytes in Obesity: Brain Cells That Control Metabolism & Cognition. A new study shows that astrocytes, star-shaped brain cells in the striatum, play a critical role in how obesity alters both brain function and metabolism. Researchers found that obesity changes the
