A recent study suggests that self-perceived successful aging is more important than traditional markers of health, with optimism and social involvement being key indicators. Participants rated their own aging as successful despite high rates of physical illness and disabilities.
A study examining genetics of successful aging identified specific genetic sequences associated with reaching old age with preserved cognitive abilities. The research also found that lifestyle factors such as smoking and excessive drinking negatively impact successful aging in both men and women.
A study of young girls referred to pediatric clinics due to alleged movement disorders found that most cases were actually normal muscle contractions during masturbation. Children can be easily distracted from these episodes, and parents should not assume harm or deviancy from the behavior.
A recent study found that low-income pregnant Latinas are at risk of early-pregnancy drinking and related effects, contrary to stereotypes. The study, which analyzed drinking behavior among 100 pregnant women, suggests that cultural values and language barriers may contribute to this risk.
Researchers at Queen's University have developed a new eye movement test to identify children with Fetal Alcohol Spectrum Disorder (FASD), which affects approximately one percent of Canadian children. The test can cut across cultural barriers and provide objectivity in identifying the disorder, allowing for improved treatment.
A study published by the University of Vermont suggests that cognitive-behavioral therapy (CBT) is a more effective long-term treatment for SAD than light therapy. The study found that patients who received CBT showed comparable improvement to those who received light therapy, but with better long-term benefits.

Young adults with problem gambling diagnoses tended to exhibit negative emotions, impulsive behavior, and risk-taking tendencies, suggesting a common underlying profile.
A study using PET scans found that cognitive behavioral therapy alters brain chemistry in patients with bulimia nervosa, particularly in regions related to feeding and reward. The results suggest a relationship between opioid receptors and bulimic behavior, potentially informing more effective treatment strategies.
Researchers found that media violence exposure may be associated with alterations in brain function, particularly in the frontal cortex, which is linked to attention and self-control. High exposure to violent media was linked to reduced activity in this area, while low exposure showed increased activity.
Researchers found significant improvement in sensory avoiding behaviors and tactile sensitivity after therapy sessions for children with ADHD. The treatment helped children better attend to lessons in noisy classrooms and participate in family activities.

Research suggests individuals with autism spectrum disorders have a dysfunctional mirror neuron system, contributing to impairments in social interaction and communication. Biofeedback and mirror therapy may be potential treatments for high-functioning autistics.
A study of 900 participants aged 21-30 found that current daily smoking predicted subsequent suicidal thoughts or attempts. Rates of suicidal behavior were higher among those experiencing depression at each follow-up assessment.
Researchers found that lithium-based drugs restored normal courtship behavior in mutant fruit flies with Fragile X syndrome, suggesting a potential new approach to treating the condition. The study also identified metabotropic glutamate receptor hyperactivity as a key contributor to the disease's symptoms.
A study by UCLA neuroscientists found that pre motor mirror neuron areas of the brain can ascribe intentions to actions when presented within a context. This expansion of knowledge supports imitation-based treatments for autism and similar disorders, which may improve social interaction skills.
A study of 201 children found that hyperkinetic disorder is associated with a higher risk of family breakdown, with 18% of affected children being removed from their homes. The findings suggest that recognizing and treating hyperactivity in children could help prevent family disruption.
A new study suggests that the anterior cingulate cortex (ACC) functions as an early warning system to help recognize and avoid high-risk situations. The ACC learns to warn us of potential mistakes before difficult decisions must be made, allowing for more careful behavior.
Researchers found abnormal brain activity in individuals with autism when observing hand movements, indicating a faulty mirror-neuron system that affects social skills and empathy. This study provides insight into the neural basis of autism's social deficits.
A study of WHO database records found 93 cases of SSRIs associated with neonatal convulsions or withdrawal syndrome. Paroxetine was linked to the most cases, suggesting it may cause more severe symptoms than other SSRIs. The findings recommend careful monitoring and lower doses for paroxetine use during pregnancy.
Researchers found that shy children with high shyness-BI indexes and specific genetic variations showed smaller responses to hostile and neutral facial expressions in certain brain regions. This suggests a biased pattern of processing emotional information, which can be recognized early in life.
A researcher created a model to simulate the dynamics of heart rhythm disorders, including ventricular tachycardia and fibrillation. The model revealed that only six spiral waves are present in the heart during fibrillation, contradicting previous assumptions about its chaotic nature.
Neurology researchers have identified an area in the prefrontal cortex that controls collecting behavior, revealing a potential link to hoarding disorders. Damage to this region can lead to abnormal hoarding behavior, interfering with daily life and causing individuals to resist discarding collected items.
A recent study published at the ACNP Conference found that exposing rats to Ritalin during early development can lead to reduced ability to experience pleasure and reward, as well as depressive-like behaviors in adulthood. This raises concerns about the long-term effects of ADHD medication on normal-functioning brains.
Children and adolescents with OCD benefit from a combination of cognitive behavioral therapy (CBT) and medication, specifically sertraline. The treatment results in significant symptom reduction for 53.6% of participants. CBT alone is also effective, with 39.3% becoming nearly asymptomatic.
A Swedish study of over 700,000 young adults found that low birthweight and being born to a teenage mother are independent risk factors for increased suicide risk. The study also showed that individuals born fourth or more in sibling order and those from poor maternal socio-economic backgrounds are at higher risk of attempted suicide.
Scientists have successfully created a mouse lacking both MAO A and MAO B, revealing the combined actions of these enzymes in neurotransmitter regulation. This breakthrough may lead to new insights into anxiety- and stress-related disorders.
The study found that pediatricians are treating more children with psychiatric problems due to chronic underfunding of the public mental health system. Many pediatricians felt unprepared to diagnose and treat anxiety and depression, highlighting the need for increased training and continuing medical education.
