A new time-release stimulant has been shown to produce significant behavioral improvements in children with ADHD, regardless of dosage. The medication offers a stable therapeutic environment and symptom control into the evening, allowing for improved daily functioning.
A new study found that adolescents with ADHD symptoms are more likely to smoke, highlighting the potential for targeting tobacco control efforts towards high-risk youth. The researchers also suggest that nicotine may help manage ADHD symptoms.
A study by Brookhaven National Laboratory found that individual variation in dopamine release affects Ritalin's efficacy in treating attention/hyperactivity disorder. The study suggests that patients with low dopamine cell activity may not respond to the drug, even if it blocks dopamine transporters.
A new study published in Neurology has demonstrated that the combination of clonidine and methylphenidate (Ritalin) is an effective treatment for children with ADHD and chronic tic disorders, with minimal side effects. The treatment was found to improve 'on task' behavior and attentiveness, while reducing symptoms of crying, frustratio...
A new study found that methylphenidate (MPH) is effective in treating children with both attention deficit hyperactivity disorder (ADHD) and tic disorders like Tourette's. The treatment was previously thought to worsen tics, but the study showed no increase in tics and even eased them in some cases.
Researchers found a genetic association between IL-1 receptor antagonist and ADHD, suggesting immune system involvement in childhood susceptibility. The study suggests that altered IL-1 activity may contribute to ADHD's dopaminergic reactivity.
Research found that older girls with ADHD often internalize their feelings and exhibit social problems, anxiety, and depression. Higher verbal IQ scores were unexpectedly associated with ADHD symptoms in girls, differing from previous research on boys.
A new study at Lehigh University will introduce alternative strategies to control ADHD symptoms in preschoolers without medication. The goal is to improve behavioral, social, and educational outcomes for young children at risk of ADHD.
Researchers at Yale University have conducted a controlled study on guanfacine, finding it to be an effective treatment for children with ADHD and tic disorders. The study showed significant improvement in symptoms, including a 37% increase in total score on the ADHD Rating Scale compared to placebo.
A new study assesses the effects of therapeutic doses of oral Ritalin on dopamine levels in healthy, adult male subjects, revealing increased dopamine levels and potential improvement in attention and focus for ADHD symptoms.
Research findings suggest that depression in children is linked to increased serotonin transporter availability, while dopamine levels are less significant. A family-based study also identifies a potential link between the DRD4 gene and ADHD, highlighting progress in understanding molecular basis of childhood mental illness.
A recent survey found significant disparities in ADHD medication treatment among Maryland public school students, with minority children receiving lower rates of medication. Special education students are almost six times more likely to receive medication for ADHD than their regular education counterparts.
A new study found that non-medicated ADHD children are three times slower than their non-ADHD counterparts when making quick decisions. However, when treated with Ritalin, the ADHD children's reaction times returned to normal.
A new study finds that carefully monitored medication treatment alone can be as effective as combination therapy in reducing ADHD symptoms. The research recommends a personalized approach, combining optimal medication doses with monthly office visits and teacher input to maximize treatment effectiveness.
A study from Massachusetts General Hospital found that treated ADHD boys are one-third as likely to develop substance abuse or dependence compared to untreated peers. The research contradicts the myth that stimulant treatment could lead to future drug abuse.
A new study funded by NIDA and NIMH found that boys with ADHD treated with stimulants like Ritalin are less likely to develop substance use disorders. The study showed an 84% reduction in risk among medicated ADHD boys, compared to non-medicated ADHD boys and those without ADHD.
A new study reveals two distinct subtypes of ADHD affecting boys and girls at similar rates, contradicting traditional assumptions about the disorder's impact on males. The research also identifies genetic factors as a key contributor to ADHD risk, with identical twins showing 80% concordance rate.
A new study has found that Adderall lasts longer than Ritalin in treating ADHD symptoms, and is at least as effective. The trial involved 25 children who took part in an eight-week program and showed significant improvements in social behavior and academic performance with both medications.
Researchers identified preferential transmission of alleles at the Dopamine transporter gene (DAT1), Dopamine-b-hydroxylase (DBH), and Dopamine D5 receptor (DRD5) in affected children. The findings suggest a possible genetic contribution to the disorder, with stronger transmission of associated alleles in familial cases.
A study using genetically engineered mice suggests that Ritalin calms humans with attention deficit hyperactivity disorder (ADHD) by affecting serotonin levels, rather than dopamine. The findings provide a new understanding of the drug's mechanism of action and could lead to more effective treatments for ADHD.
Ritalin and other stimulants appear to restore balance between dopamine and serotonin, calming hyperactivity. The study suggests that targeting serotonin may be a more effective approach to treating Attention Deficit Hyperactivity Disorder (ADHD) than previously thought.
Researchers found that Ritalin reduces activation in the cerebellum and basal ganglia while increasing activation in novel areas of the brain, improving working memory in ADHD patients. This study provides new clues for developing more specific drug treatment for individuals with ADHD.
A recent study found that chronically ill children are more likely to experience poor adjustment, including hostility or withdrawal, regardless of the illness type. The researchers controlled for social and economic factors but still observed a significant difference between chronically ill and healthy children.
A population association study found a higher percentage of the 7 repeat allele and 7+ genotype in ADHD children compared to controls. The study also identified significant positive results from a family-based approach, providing additional evidence for an association between DRD4 gene and ADHD.
A newly released intelligence test can help diagnose Attention Deficit Hyperactivity Disorder (ADHD) in children by measuring their planning ability. The test, called the Cognitive Assessment System (CAS), showed that children with ADHD scored significantly lower than average on CAS in a measurement of planning ability.
Research at Emory University Health Sciences Center found that individuals with ADHD tend to integrate information in more visual and less auditory ways, which may explain their everyday difficulties. The study used PET scans to evaluate working memory in ADHD patients and normal control subjects.
Researchers discovered novel genetic associations with ADHD, including a strong link between the dopamine transporter gene and symptoms. These findings may lead to improved diagnostic tools and targeted treatments for ADHD.
Studies suggest that slow stop-signal reaction time is responsible for poor impulse control in individuals with ADHD. Researchers are developing an objective diagnostic technique to refine understanding of ADHD and improve diagnosis.
Children with FAS have behavioral and learning problems in addition to brain damage and facial abnormalities. Researchers found that children with FAS can focus on tasks but struggle with using new information and switching attention, which may explain why drugs like Ritalin are ineffective for this group.
A comprehensive brain imaging study confirms subtle structural abnormalities in the brain circuit responsible for executive functions in Attention Deficit Hyperactivity Disorder (ADHD). The study found smaller right hemisphere brain structures and abnormally symmetrical brains in boys with ADHD.
