Psychiatry-Neuropsychiatry Flashcards
A patient comes in speaking without emotional modulation during speech an no appreciation for music. Which hemisphere is likely affected?
The right hemisphere is responsible for these things.
What region of the brain mediates executive functions?
Prefrontal cortex
What region of the frontal lobe is affected in people who exhibit social impropriety? Disorganization? Disinterest and only respond to external stimuli?
Social impropriety = orbitofrontal. Disorganization = dorsolateral. Disinterest = medial (cingulate)
Executive functions
Ability of the brain to plan, organize, think, abstract and problem solve.
What region of the brain is responsible for telling you that you are holding a remote control when your eyes are closed?
Parietal lobe is responsible for 3D representation. It integrates the information coming from the somatosensory cortex with the visual cortex in the occipital lobe.
Dominant parietal lobe
Language
Non-dominant parietal lobe
Creates the 3D representation of own body. This is why patients experience anosognosia, contralateral hemineglect when there are lesions in the right parietal lobe, they can see the limb, but don’t know it’s a part of their own body.
Visual association area
Parietal-Occipital junction
Part of the brain involved in hearing and decoding language?
Dominant temporal lobe
Part of the brain involved in learning from experience?
Hippocampus in the temporal lobe
Part of the brain involved in recognizing faces and reading emotions?
Temporal lobe amygdala
A patient has a stroke and now speaks with zero emotion. What region of the brain was affected?
The non-dominant equivalent of Broca’s area.
A patient has a TBI and now cannot integrate the emotion in other people’s language. What region of the brain was affected?
The non-dominant equivalent of Wernicke’s area
What region of the brain integrate visual input to determine where you are in 3D space? What region integrates visual input to determine what you are seeing?
3D space = parietal lobe. Dictionary = temporal lobe.
A patient has a TBI and can no longer understand what people are saying. He can still understand written words. Where in the brain was the damage?
Wernicke’s area
A patient has a TBI and presents with right sided paralysis, inability to speak, dementia and depression. Where in the brain is his injury?
The left hemisphere: motor cortex, Broca’s area, Wernicke’s, limbic and hippocampus damage
A patine presents with a TBI and left sided weakness, aggressive impulsive behavior and inability to plan and organize his life. Where is the likely location of brain injury?
Frontal cortex
