Thinking blocks and decision-making problems in ADHD - neurophysiological correlates


Thinking blocks and decision-making problems in ADHD - neurophysiological correlates

Thinking blocks occur equally in ADHD-HI and ADHD-I. Contrary to a view previously expressed here, they are not subtype-specific. Decision-making problems, on the other hand, appear to occur significantly more frequently in ADHD-I than in ADHD.

This suggests that the two manifestations have different neurophysiological correlates.

The extremely high levels of noradrenaline during severe stress impair the functionality of the PFC. While slightly elevated noradrenaline levels increase the ability to think, very high noradrenaline levels reduce this ability and behavioral control is transferred from the PFC to the posterior cortex.1234

The details can be found in the article Neurotransmitters during stress In the section Severe stress = strong increase in NE/DA and cortisol = reduced cognitive performance.
