explinations of OCD Flashcards
what is an example of an explanation of OCD
neuroanatomical explination
what does this explanation say OCD is caused by
maladaptive cognition
what is the neuroanatomical explination of OCD
due to dysfunction in a neuronal loop. these regions of the brain form a circuit that converts sensory info into thoughts and actions
what are the four elements of the brain involved in explination of OCD
orbital cortex
caudate nucli
thalamus
cigulate gyrius
what does the orbital frontal cortex do
cognative process of decision making
what conversion does the orbital frontal cortex do
converts sensory info into thoughts and alerts brain to potential worries in enviroment
what leads to an increase in syptoms in the brain
overactivity
what does overactivity in the orbitalfrontal cortex lead to
increase in conversion of sensory to actions
what does this increase in the conversions of sensory to actions lead to
worry
what else does overstimulation in the orbital frontal cortex lead to
compulsion and inability to stop
what does the orbital frontal cortex lead to
caudate nucli
what is the passage of thought that connects these together
message panic / worry
what does the caudate nuclei do
decide whether a message is important or not
what else does the caudate nuclei act as
filter for information into the thalumus suppressing worry signals
what does over activity in the caudate nuclei lead to
impared function
what does this improved function mean
faulty messages of worry / panic passed throughout the thalamus
what do these faulty messages of worry mean
individual is driven more to think about and take action
what does the caudate nuceli lead to
thalamus
what id the thalamus responsible for
responds to sensory and motor
what does this response mean
it carry’s out nessary action
what is the connection from the caudate nuclei to the thalumus connected by
faulty messages
panic
what does overactivity in the thalamus lead to
compulsion to engage in behaviuors
if a paiintent had a fear of contaminiation what would there orbital frontal cortex response be
touched a door knob covered in germs – [very dangerous germs make ill and die]
what does this then lead the paitent to do
process as a viable panic
worry germs unhygenic will make them very ill
what is then the belife that leads to the compulsion
wil become ill and die
what does overactivity in the thalamus make the paitent do
wash hands excessively
what does this compulsion of excessive hand washing lead to
emotional relife
