Week 13 NEURO Flashcards
Infant CN 1
Olfactory
Difficult to test
how to test for visual acuity in infants? CN?
CN II
Optic
look for facial response & tracking
How to test for response to light in infants? CN?
CN II & III
Optic & Oculomotor
darken room
Optic blink reflex
pupillary response
How to test for EOM in infants? CN?
CN 3, 4, 6
Oculomotor, Trochlear, Abducens
how well infant tracks smiling face & if eyes move together
How to test for the motor system in infants? CN?
CN 5 Trigeminal
rooting reflex
suckling reflex & strength of suck
How to test the infant’s face? CN?
what does an abnormal response mean?
CN 7 Facial
Observe infant crying; symmetrical?
Asymmetry = congenital facial nerve palsy from birth trauma or developmental defects
How to test acoustics with infant? which CN?
CN 8 Vestibulocochlear
Blinking of both eyes in response to loud noise
Observe tracking in response to sound
How to test swallowing with infant? CN?
CN 9 & 10
Glossopharyngeal & Vagus
observe coordination with swallowing
Gag reflex
Dysphagia in an infant indicates injury to what cranial nerves?
Injury to CN 9, 10, 12
Glossopharyngeal, Vagus, Hypoglossal
How to test spinal accessory in infant? CN?
CN 11 Spinal Accessory
symmetry of shoulders
how to test hypoglossal in infant? CN?
CN 12 Hypoglossal
coordination of sucking, swallowing and tongue thrusting
Pinch nostrils; tongue midline?
Palmar Grasp reflex
Maneuver
Age
Meaning if it goes beyond? #2
fingers in infants hand
AGE:
Birth - 4 months
PERSISTENCE:
-beyond 6 months suggests pyramidal tract dysfx
-Persistance beyond 2 months= CNS damage, especially
if fingers over lap thumb
Plantar Grasp Reflex
Maneuver
AGE
persistence meaning?
Touch base of toes; toes should curl
AGE:
Birth - 8 months
PERSISTENCE:
-Pyramidal tract dysfx (corticospinal tract)
Rooting Reflex
Maneuver
AGE
absence?
Stroke perioral corners; mouth should open and infant turn head to suck
AGE
Birth - 4 months
ABSENCE:
generalized or CNS disease
Moro reflex
Maneuver
age
persistence
assymmetry
“startle reflex”
Abruptly lower supine infant 1 foot; arms abduct, hands open, legs flex
AGE
birth - 4 months
PERSISTENCE: Neurologic disease (CP) esp if beyond 6 months
ASYMMETRY:
clavicle/humerus fracture
brachial plexus injury
Asymmetric tonic neck reflex
maneuver
age
persistence
turn head to one side, holding jaw over shoulder; opposite arm/leg will flex
AGE
Birth - 3 months
PERSISTENCE:
asymmetric CNS development
CP development
Galant Reflex
maneuver
age
absence
persistence
“Trunk Incurvation”
Prone infant & stroke 1 side of back 1cm from midline; spine should curve toward the stimulated side
AGE
Birth - 4 months
ABSENCE:
transverse SCI
PERSISTENCE:
delayed development
Landau reflex
maneuver
age
persistence
suspend infant prone; the head should lift & spine straighten
AGE
Birth - 6 months
PERSISTENCE:
delayed development
Parachute reflex
maneuver
age
DELAY
prone infant & lower head to surface; arms and legs extend
AGE:
8 months - lifetime
DELAY:
predict future delays in voluntary motor development
Positive support reflex
maneuver & what’s normal?
age
meaning if there’s no reflex?
Meaning if there is only fixed extension & adduction?
hold infant around trunk until both feet touch surface; partial weight-bearing
AGE:
birth/2mos. - 6 months
:
NO REFLEX = flaccidity or hypotonia
-Fixed extension & Adduction (SCISSORING) = spasticity/neuro disease (CP)
Placing and Stepping reflex
maneuver
age
absence
hold upright w/ one foot touch surface; alternate stepping
AGE:
Birth - varies
ABSENCE = paralysis
*breech delivery may not have this
Define lethargy
drowsy, opens eyes when spoken to in LOUD VOICE
response to questions then falls asleep
Define Obtundation
opens uses with TACTILE STIMULUS
looks at you, responds slowly & CONFUSED
define stupor
arouses with PAINFUL stimuli
unresponsive when stimulus stops
