Dynamic Expression of Brain Serotonin Receptors Across the Menstrual Cycle Provides Clues About Premenstrual Dysphoric Disorder
Roughly, 3 to 8% of women suffer from premenstrual dysphoric disorder (PMDD), a disorder that causes anxiety, depression, and mood swings during the menstruation cycle. PMDD appears to increase serotonin transporter density from the preovulation phase to the premenstrual cycle phase. The findings could aid in the development of new treatments for PMDD.
Brain Structural Differences Observed in Children With Conduct Disorder With and Without Childhood Maltreatment
Children with conduct disorders who were exposed to maltreatment showed far more extensive changes in brain structure compared to children with conduct disorders who were not mistreated.
Brain levels of FAAH, an enzyme that degrades a neurotransmitter that activates the cannabinoid 1 receptor, may contribute to the maintenance of excessive drinking and susceptibility to alcohol use disorder.
Greater amygdala reactivity during the anticipation of social punishment predicted a greater risk of non-suicidal self-harm one year later in adolescents.
Recent studies have suggested there is not enough evidence to support the serotonin hypothesis for depression. However, a new study shows direct evidence of disrupted serotonin release in the brains of those with depression.
Study reveals how methylphenidate interacts with cognitive control networks and attention behaviors. Methylphenidate changes spontaneous neural activity in reward and cognitive control systems in children with ADHD. The changes result in more stable sustained attention.

Skipping Meals, Fasting and Eating Meals Too Closely Together May Be Linked to Increased Mortality Risk
A new study links daily eating to mortality risk. Those over 40 who eat one meal a day have a higher mortality risk. Those who skip breakfast are at an increased risk of cardiovascular disease-associated death, and those who eat meals less than 4.5 hours apart have increased mortality risks.
