What does damage to parietal lobe do?
|
Damage to parietal lobe: problem identifying objects using touch (without vision) → astereognosis (disconnect b/w touch and memory)

|
What is astereognosis?
|
Damage to parietal lobe: problem identifying objects using touch (without vision) → astereognosis (disconnection between touch and memory)

|
Categories (order matters)
o Attention: always tested first, if you cannot pay attention you cannot do these other tests o Language o Memory o Visuospatial/perceptual o Executive functions |

|
Attention - always tested first, if you cannot pay attention you cannot do these other tests
|
|
How to do mental status exam for attention? (4)
|
* Observe the patient
(if person follows you with their eyes and responds to you, they are paying attention)
* Count backwards from 20 (attention problem → will lose track) * Months forward, backward * Sustained attention: holding attention for a duration of time |

|
Mental status exam, Test for language (5):
|
o Fluency: ability to produce language (mute, stutter)
o Naming common objects o Repetition (being able to repeat speech) o Prosody: tone in which you speak (damage to right side – prosody flattens out) o Comprehension: understanding (can indicate w/ words, actions → if cannot talk) o Reading o Writing o Praxis: ability to follow verbal commands into actions (tested by tool use – left hemisphere damage confuse body with object) |
|

|
inability to name things due to a brain injury
|
|
What is Praxis?
|
ability to follow verbal commands into actions (tested by tool use – left hemisphere damage confuse body with object)
|
|
What is Prosody?
|
tone in which you speak (damage to right side – prosody flattens out)
|
|
In mental status exam, how do you check for memory?
|
o Digit span, pointing span → does not require language
• average people can remember 5-9, if they cannot there is a problem o Verbal, visual object learning o Past public/personal events (must have a family member present) o Factual knowledge |
|
Where is language mostly located?
|
Left hemisphere
|
|
Where is memory located(4)?
|
Medial temporal lobes, thalamus, basal forebrain, frontal lobes
|
|
How is Visuospatial/perceptual checked in a mental status exam?
|
o Copy of geometric designs (if cannot – brains ability to interpret images is compromised)
o Judgment of line orientation o Object/face/color recognition |
|
Where is Visuospatial/perceptual located?
|
Right hemisphere
|
|
how are executive functions checked in mental status exam?
|
o Judgment: making simple decisions
o Verbal fluency: people with impairments do not categorize, are slower, produce less info o Luria 3-step: continuously doing the same steps over and over, gets stuck, understands what they are supposed to do o Coin switch task o Drawing loops, alternating patterns: get stuck on a letter or number o Oral trail making test: alternate between letters and numbers (A1B2, etc) o Perseveration: continue to do the same thing over and over again when it is no longer appropriate |
|
Where are executive functions located?
|
o Frontal lobes
