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.
Psychostimulants increase dopamine levels, enhancing task-relevant cortical signals by acting on the striatum and the difference in dopamine synthesis capacity in the striatum explains the variability in the drugs' cognitive effects.
A new study of male guppies reveals behaviors affected by methylphenidate hydrochloride (MPH), an active ingredient in common ADHD medications, can be passed along to future generations.
Even at doses that help improve monkeys' attention, researchers observe no differences of neural activity in the prefrontal cortex after administering Ritalin.
A new neuroimaging study reveals methylphenidate, better known as Ritalin, increases the level of dopamine available in the caudate. Along with increased dopamine levels, researchers also notice greater functional connectivity between the prefrontal cortex, hippocampus and precuneus, three areas of the brain associated with memory and attention.
A new study reports those with ADHD are at an increased risk of developing Parkinson's disease. The study reveals people with ADHD are twice as likely to develop early onset Parkinson's between the ages of 21-66. Additionally, those who are prescribed stimulant medications to help reduce ADHD symptoms, including Ritalin and Adderal, are at a 6-8 times increased risk of developing Parkinson's.
Researchers report, contrary to popular belief, Adderall and other ADHD drugs do not improve cognition in healthy college students. Instead, they may impair cognitive function.
Researchers report changes in brain chemistry in people who take the medication Ritalin without it being prescribed to them. Changes impacted body weight, risk taking behaviors and locomotive activity. Additionally, women were more sensitive to the behavioral effects that men.
According to researchers, mixing high energy drinks with alcohol triggers changes in the teen brain similar to those experiences when taking cocaine.
A new study reports the a majority of Swiss students questioned were against the use of cognitive enhancement drugs.
