1 THE NEUROLOGICAL EXAMINATION

2 NEUROLOGICAL EXAM MENTAL STATUS CRANIAL NERVES MOTOR EXAM REFLEXES
STRENGTH GAIT CEREBELLAR REFLEXES SENSATION

3 MENTAL STATUS

4 Level of Consciousness
Awake and alert Agitated Lethargic Arousable with Voice Gentle stimulation Painful/vigorous stimulation Comatose

5 LANGUAGE FLUENCY NAMING REPETITION READING WRITING COMPREHENSION
Aphasia vs. dysarthria

6 MEMORY IMMEDIATE REMOTE 3 OBJECTS AT 0/3/5 MINUTES HISTORICAL EVENTS
REALLY A MEASURE OF ATTENTION RATHER THAN MEMORY REMOTE 3 OBJECTS AT 0/3/5 MINUTES HISTORICAL EVENTS PERSONAL EVENTS

7 ORIENTATION PERSON NOT WHO THEY ARE BUT WHO YOU ARE PLACE TIME

8 OTHER COGNITIVE FUNCTIONS
CALCULATION ABSTRACTION SIMILARITIES/DIFFERENCES JUDGEMENT PERSONALITY/BEHAVIOR

9 CRANIAL NERVES

10 CRANIAL NERVE EXAM I - OLFACTORY II - OPTIC
DON’T USE A NOXIOUS STIMULUS COFFEE, LEMON EXTRACT II - OPTIC VISUAL ACUITY VISUAL FIELDS FUNDOSCOPIC EXAM

11 CRANIAL NERVE EXAM III/IV/VI OCULMOTOR, TROCHLEAR, ABDUCENS
PUPILLARY RESPONSE EYE MOVEMENTS 9 CARDINAL POSITIONS OBSERVE LIDS FOR PTOSIS V - TRIGEMINAL MOTOR - JAW STRENGTH SENS - ALL 3 DIVISIONS

12 CRANIAL NERVES VII - FACIAL VIII - VESTIBULAR
OBSERVE FOR FACIAL ASYMMETRY FOREHEAD WRINKLING, EYELID CLOSURE, WHISTLE/PUCKER VIII - VESTIBULAR ACUITY RINNE, WEBER

13 CRANIAL NERVES IX/X - GLOSSOPHARYNGEAL, VAGUS XI - SPINAL ACCESSORY
GAG XI - SPINAL ACCESSORY STERNOCLEIDOMASTOID M. TRAPEZIUS MUSCLE XII - HYPOGLOSSAL TONGUE STRENGTH RIGHT XII THRUSTS TONGUE TO LEFT

14 MOTOR EXAMINATION

15 STRENGTH STRENGTH GRADED 0 - 5 0 - NO MOVEMENT 1 - FLICKER
2 - MOVEMENT WITH GRAVITY REMOVED 3 - MOVEMENT AGAINST GRAVITY 4 - MOVEMENT AGAINST RESISTANCE 5 - NORMAL STRENGTH

16 STRENGTH EXAM UPPER AND LOWER EXTREMITIES DISTAL AND PROXIMAL MUSCLES
GRIP STRENGTH IS A POOR SCREENING TOOL FOR STRENGTH SUBTLE WEAKNESS TOE WALK, HEEL WALK OUT OF CHAIR DEEP KNEE BEND

17 Subtle signs of weakness on a cortical/subcortical basis
Motor exam, cont Subtle signs of weakness on a cortical/subcortical basis Pronator drift Orbiting

18 Gait evaluation Include walking and turning Examples of abnormal gait
High steppage Waddling Hemiparetic Shuffling Turns en bloc

19 MUSCLE OBSERVATION ATROPHY FASCIULATIONS

20 ABNORMAL MOVEMENTS TREMOR CHOREA ATHETOSIS ABNORMAL POSTURES REST
WITH ARMS OUTSTRETCHED INTENTION CHOREA ATHETOSIS ABNORMAL POSTURES

21 CEREBELLAR FUNCTION RAPID ALTERNATING MOVEMENTS
FINGER TO FINGER TO NOSE TESTING HEEL TO SHIN GAIT TANDEM

22 Romberg Sign Stand with feet together - assure patient stable - have them close eyes Romberg is positive if they do worse with eyes closed Measures Cerebellar function Frequently poor balance with eyes open and closed Proprioception Frequently do worse with eyes closed Vestibular system

23 REFLEXES

24 MUSCLE STRETCH REFLEXES (DEEP TENDON REFLEXES)
GRADED 0 - 5 0 - ABSENT 1 - PRESENT WITH REINFORCEMENT 2 - NORMAL 3 - ENHANCED 4 - UNSUSTAINED CLONUS 5 - SUSTAINED CLONUS

25 MSR / DTR BICEPS BRACHIORADIALIS TRICEPS KNEE ANKLE

26 OTHER REFLEXES Upper motor neuron dysfunction Frontal release signs
BABINSKI present or absent toes downgoing/ flexor plantar response HOFMAN’S JAW JERK Frontal release signs GRASP SNOUT SUCK PALMOMENTAL

27 TONE INCREASED, DECREASED, NORMAL COGWHEELING CLASP KNIFE

28 SENSORY EXAM

29 SENSORY EXAM VIBRATION JOINT POSITION SENSE PIN PRICK TEMPERATURE
128 hz tuning fork JOINT POSITION SENSE PIN PRICK TEMPERATURE Start distally and move proximally

30 HIGHER CORTICAL SENSATIONS
GRAPHESTHESIA STEREOGNOSIS DOUBLE SIMULTANEOUS STIMULATION BAROSTHESIA TEXTURES
