Neurobiology Final Module 7 Flashcards
ADHD symptoms occur d/t:
malfunctioning of the neuronal circuits of the PFC
Why do circuits malfunction with ADHD patients?
dysregulation of DA and NE
Treatment for ADHD focuses on _____ DA and NE release in the PFC
enhancing
Put the following in order of treatment:
ADHD
mood and anxiety
alcohol and substance use
nicotine dependence
alcohol and substance use
mood and anxiety
ADHD
nicotine
antagonizes transporters for both NE (NET) and DA (DAT). The result is enhanced function of both
methylphenidate
blocks the transporters both for NE and DA, competitive inhibitor and pseudosubstrate for both NET and DAT, work by inhibiting NE and DA uptake
amphetamine
list SE for stimulants (6)
increased wakefulness
increased arousal
increased BP
increased HR
irritability
appetite suppression
stimulants increase _____ and _____ activity
DA, NE
increases NE and DA in the PFC without abuse potential d/t not increasing NE and DA in the _____
SNRIs
nucleus accumbens
give an example of an SNRI
atomoxetine
side effects of SNRIs (3)
increased BP
increased HR
sedation
(sympathomimetic)
stimulate a2A receptors (autoreceptors) which mitigate NE functions in the PFC (2 examples)
a2A adrenergic agonists
guanfacine
clonidine
which drug is more selective for a2A
guanfacine
which drug is non-selective for a2A
clonidine
what is clonidine used off-label for?
ADHD (bxs linked with low levels of NE and low levels of DA in the VMPFC) argumentative, disobedient, aggressive, temper tantrums
