What is a key clinical presentation of ADHD
symptoms must interfere with functioning and development
where is the circuity mechanism in the brain
medial prefrontal cortex

methylxanthines (indirect-acting sympathomimetics
what is an example of a methyxanthine
caffeine
what receptor is antagonized by methylxanthines
adenosine receptors
are methylxanthines antagonists or agonists
antagonists
what is the result of methylxanthines on cAMP
increase cAMP, inhibit phosphodiesterases
what is the result of methylxanthines on ryanodime receptors
increase activity which increases intracellular ca2+

adenosine receptors
three effects that result from activation of adenosine receptors in the CNS
sedation, anxiolysis, anticonvulsant activity
