Neuro Flashcards
Sx that prompt a neuro exam
Headache
Dizziness/ Vertigo
Weakness
Loss of sensation
Seizures
Stroke like sx
Confusion
Altered mental status
Intoxication
Components of Neurological exam
Mental status exam
Cranial nerve evaluation
Motor function evaluation
Sensory function evaluation
Reflexes
What does mental status exam look for?
Level of alertness
Appropriateness of responses
Orientation to date and place
A patient is ALERT if they …. (3 things)
Speak to you in normal tone of voice
Are awake
Respond to their surroundings
What does A&O x3 indicate?
Patient alert and oriented to person, place and time
Mini-Mental Status Exam is used to screen for……
Cognitive impairment and dementia
The MMSE has questions regarding:
Level of consciousness (arousal)
Attention and concentration
Memory (immediate, recent, remote)
Language
Visual spatial perception
Executive functioning
Mood and thought content
Calculations
Cranial Nerves (I-XII) names
I- Olfactory
II- Optic
III- Occulomotor
IV- Trochlear
V- Trigeminal
VI- Abducens
VII- facial
VIII- acoustic
IX- Glassopharyngeal
X- Vagus
XI- Accessory
XII- Hypoglossal
Function of CN I
Sense of smell
Function of CN II
Vision
What CN’s are responsible for medial deviation, medial upward deviation, lateral upward and lateral downward devaition of the eyeball
CN III
What CN is responsible for medial downward deviation of the eye (SO4LR6)
CN IV (superior oblique)
What CN is responsible for lateral deviation of the eye (SO4LR6)
CN VI
Function of CN III
Pupillary constriction
Lid elevation
Most Extraocular movements
Function of CN IV
Trochlear
Downward, internal rotation of the eye
Function of CN V
Trigeminal
Motor—> temporal and mass enter muscles (jaw clenching), lateral pterygoids (lateral jaw movment)
Sensory—> facial (1)opthalmic, (2) maxillary, (3) mandibular
Function of CN VI
Abducens
Lateral deviation of the eye
Function CN VII
Facial
Motor- facial movements
- facial expression
- closing eye
- closing mouth
Sensory- taste for salty, sweet, sour bitter substances on ANTERIOR 2/3 TONGUE
- sear sensation
Function CN VIII
Acoustic
Hearing— cochlear division
Balance— vestibular division
Function CN IX
Glassopharyngeal
Motor- pharynx
Sensory- POSTERIOR eardrum and ear canal, pharynx, POSTERIOR TONGUE (including taste)
Function CN X
Vagus
Motor- palate, phayrnx, larynx
Sensory- pharynx, larynx
Function CN XI
Accessory
Motor- sternocleoidmastoid and upper traps
CN XII
Hypoglossal
Motor to tongue

Rapid, shock-like jerks
Myoclonus
Rapid, jerky twitches similar to myoclonus but MORE RANDOM in location and more likely to blend into one another
Chorea
Slow, writhing movements of limbs
Athetosis
Abrupt, stereotyped, coordinated movements OR VOCALIZATIONS
Tics
maintenance of an abnormal posture or receptive twisting motion
Dystonia
Muscle tone
Qualitatively assessed by asking the patient to relax and let you manipulate limbs passively
Increased resistance
Hypertonic
Decreased resistance (flaccid)
Hypotonia
