The core symptoms of ADHD are linked to what area of the brain? -
ANS✔✔---prefrontal cortex
)
sustained attention and problem solving linked to what area of the brain? -
ANS✔✔---DLPFC
hyperactivity is linked to what area of the brain? - ANS✔✔---prefrontal motor
cortex
what test assessing sustained attention? - ANS✔✔---N-back test
where is sustained attention modulated in brain? - ANS✔✔---CSTC loop in
the DLPFC
insufficient activation in the DLPFC can cause inattention
"sustaiNed attention- N back"
,what test assesses selective attention? - ANS✔✔---Stroop test
"Selective, Stroop, Cingulate"
where in the brain is selective attention modulated? - ANS✔✔---the CSTC
loop, Dorsal anterior cingulate cortex
Selective attention is due to what area of the PFC malfunctioning? -
ANS✔✔---dorsal ACC (anterior cingulate cortex
issues with sustained attention are: - ANS✔✔---difficulty completing tasks
disorganization
trouble sustaining mental effort
issues with selective attention are: - ANS✔✔---difficulty with detail
carless mistakes
not listening
losing things
being distracted
forgetting things
what symptoms of impulsitivity are observed? - ANS✔✔---talking
excessively
blurting things out
not waiting ones turn
interrupting
what part of the brain modulates hyperactivity? - ANS✔✔---prefrontal cortex
, what part of the brain modulates impulsitivity? - ANS✔✔---orbitofrontal
cortex
what are some key observations in the prefrontal cortex as it relates to ADHD? -
ANS✔✔---orbitofrontal cortex (OFC)-- impulsivity and hyperactivity
DLPFC/DaCC-- sustained/selective attention issues
how do NE and DA amounts manifest in relation to fatigue/anxiety? -
ANS✔✔---too little NE and DA = fatigue
too much = anxiety
what two receptors in the PRC are thought to be involved with ADHD treatment?
- ANS✔✔---alpha 2 a
D1
how does ADHD affect NE and DA levels? - ANS✔✔---NE levels low, signal
reduced
DA levels low, noise increased
results in: fidget and inattention
how should you treat NE and DA in adhd? - ANS✔✔---increase NE
Increase DA
