History Taking & Clinical Examination in neurology
During the history and clinical examination 2 points are important:
Where is the pathology?
What is the pathology?
History Taking
What is different in neurology is that the sequelae of events is
more important than the more details regarding some symptoms.
Ask the following questions or the patient will present with one of
the followings:
1) Weakness:
whether it is started from the proximal or distally i.e centrally
or peripherally.
2) Numbness and parasthesia:
numbness is the tingling sensation which is due to excitation
while the parasthesia is the loss of sensation and it is due to
inhibition.
2
3) Headache:
ask about(site, bilateral or unilateral, aggravating and relieving
factors as increase during sleep as in ICP or relief by sleep in HTN
other factors as phototherapy, any associated features as N/V and
weakness and loss of consciousness and any epileptic attack, can
be relieve by taking certain medication, is it associated with
blurred vision and any lacrimation and any hearing problems , then
the onset of headache , is it intermittent or continuous , is there any
previous attack, is it severe or not i.e can interfere with daily
activity and make the patient to stay at home and remain in bed, is
it relive by vomiting, at which time is more during the day time or
night, is there any medical disease and HTN).
4)Visual disturbance:
as blurring vision and decrease visual acuity or any double
vision.
5) Hearing disturbance:
as fluctuating deafness which is more after 50 years of age
as the patient not hear well from short distance later it will be
changed and can be found in Mienerer's disease;
6) Vertigo:
the followings are the features of true vertigo:
3
- Feeling of rotation.
-Sudden retro or propulsion
-Sinking and upward going of what is patient seeing.
7) Sphincteric disturbance:
ask about the followings:
* urinary incontinence( when the bladder is full dripping of urine
occur).
* urgent incontinence (whenever there is urine in bladder even it is
not full dripping of urine occur)
* frequency ( micturation daily more than 7 times)
* retention of urine.
8) Swallowing difficulties:
that associated with speech disturbance as nasal speech, aspiration,
nasal regurgitation.
Note :
if there is dysphagia for solid meal only mean the organic cause,
but for both solid and liquid mean neurological causes.
9) Loss of consciousness which is inhibitory.
10)Epilepsy which is excitation.
4
11)Then any other disease as (DM, HTN , cardiac disease , drugs)
Notes:
*Center of consciousness is located in reticular activating system
that we have cerebral hemisphere, thalamus, midbrain-pons-
medulla
oblongata.
* When there is sudden loss of consciousness mean brainstem
lesion.
* Almost both thalamus should be affected in order loss of
consciousness to occur and usually it is not sudden loss.
Clinical Examination
Include 2 main parts :
A) General examination
1. Consciousness.
2. orientation
3. memory
4. speech
5. GAIT.
B) Specific examination:
5
1. cranial nerve examination
2. meningeal signs
3. motor system examination
4. co-ordination
5. Sensory system examination.
Cranial nerve Examination
Remember we have 12 cranial nerves , and ( 1, 2,8 are sensory)
and (4,6,7,11,12 are motor) and (3,5,9,10 are mixed).
(1st is central and arise from the nasal mucosa, 2nd is central from
retina), (3rd and 4th from midbrain , 5th,6th,7th,8th are from pons ,
9th, 10th , 11st, 12nd are from medulla oblongata).. from 3rd to
12nd are peripheral.
Olfactory nerve
It can be examined by asking the patient to close the eyes then we
introduce certain but common and non irritable substance to each
6
nostril that should be examined separately and then we ask the
patient to name that substance.
Smell receptors are in the nasal cavity, the olfactory nerve is going
under the frontal lobe through the cribriform plate under roof of
nasal cavity and it is from the anterior part of brain . its function is
smell.
The loss of smell is called ( anosmia) as may be due to head injury
or tumor, while the perversion of smell is called paronosmia.
Optic nerve
Its function is vision. The nerve start from globe and passes
through the optic canal of sphenoid bone then join with other nerve
that form optic chiasma then optic tract that pass to geniculate
body of thalamus then to area of 17 or visual cortex in occipital
lobe.
The pupillary light reflex had efferent part by 3rd CN and the
afferent part by 2nd CN.
The defect in this nerve can cause some abnormalities as blurring
vision, hemianopia especially the homonimus hemianopia( the
right eye-defect in nasal part of left and temporal part of right eye
occur) which is loss of half of visual field in one or both eyes and
this may be due to pituitary tumour that compress the optic tract or
7
radiation or the bitemporal hemianopia due to defect in optic
chiasma.
Scotoma means the presence of blind spot that surrounded by the
normal visual field and the central scotoma is normal it is either
relative or absolute scotoma.
The component of examination are:
Visual acuity:
this can be examined by using the Snellen chart that is 6/6,6/9,
6/12, 6/18, 6/24,6/36,6/60. if this not done then counting fingers
from half meter that should be done for each eye separately by
asking the if this not response then hand movement, then light
perception as a last choice.
8
Visual field:
this can be tested by confrontation test that you as an examiner
will sit in front of the patient but both of you should be at the same
level then you cover one of your eye and ask the patient to cover
the reverse eye , then you use a subject better with red head and
then move it to right, left, up, down infront of the patient but ask
the patient to look to it only by his opened eye without using the
head then repeat it to the other eye to see the field of vision.
Light reflex:
the light reflex is carried by optic nerve and then will be
return back by the 3rd CN that causing the constriction of pupil.
This reflex is 2 types which is direct (the eye that you put the light
on it) and the indirect (or called the consensual reflex) (mean the
other eye). This test is done by using the torch from the lateral but
should be as a brisk movement on the eye but avoid putting the
9
light in 90 degree on the eye then look to the pupil whether
constricted or not.
Color vision: by using ishihara test.
Fundoscopy:
the patient and you should be at the same level and should be at 45
degree position and the patient should look to the prime
position or straight forward then putting one of your hand on the
head of patient and then using the scope laterally. The aim is to
look to the optic disc to know whether there is optic atrophy
(vessels are thin and margin is very white) or the papilledema
(which indicate the old lesion in which there is decrease or absent
margin, hyperemia and engorgement of vessels occur).
10
Oculomotor ,trochlear and abducent nerves
The rule is that SO4, LR6 and MIIS3(medial rectus, inferior
oblique, inferior rectus , superior rectus).
Defect in 3rd make unable to look up,down,medially(dysconjugate
gaze), ptosis , dilated pupil and loss of accommodation reflex and
divergent squint occur.The cause maybe DM.
Defect in 4th CN the patient can not look downward,
and defect in 6th CN there is convergent squint.
The examination is as followings:
• Ask the patient to look straight forward then by inspection look
for 3Ps( pupil to know regular,round , and then look for ptosis-
lowset upper eye lid- then the proptosis by doing the Naffziger as 11
stand from behind the patient and then tilt the head inward and
look to the eye whether outside the imaginary anterior line or not).
* Then in first eye movement as putting one of your hand on the
head of patient and then by your finger or a subject better with red
head move it to the right, left, up, down and ask the patient to look
to it only using the eyes without moving the head, at that time look
for any nystagmus or squint or diplopia but this ask the patient do
u see that subject in one or two.
*Accommodation reflex: the reflex is positive and god only if the
followings occurred and this by sitting in front of the patient and
using the same above directly between the both eyes and move it
toward the patient by looking to it:
1. if both eyes are partially ptosed.
2. constriction of both pupils.
3. converging of both eye medially.
*Light reflex.
12
Trigeminal nerve
The nerve has 2 branches motor and sensory. The motor will
supply the muscle of mastication which are (Masseter , Temporalis
muscle ,lateral and medial pterygoid muscles).
The sensory has 3 branches which are ophthalmic, maxillary and
mandibular branches and has the sensory function of pain and
temperature of scalp, face, lip, mouth, eyes and the ant.2/3rd of the
tongue.
The lesion of this nerve causing loss of sensation of the previous
areas and wasting of temporalis and masseter muscles and called
(trigeminal neuralgia- Tic Douloureux) that may be due to tumor,
vascular spasm, MS.
The examination is done as the followings:
Motor examination:(almost done before sensory branch):
- Look to the masseter and temporalis for any wasting and then ask
the patient to open the mouth for any jaw deviation.
13
- Ask the patient to clinch the teeth then palpate the masseter and
temporalis muscles.
-Then put your hand under the chin and ask the patient to open it
against the ur hand resistant as much as he or she can then move
the chin to right and left against your hand beside that side.
- Reflex Examination: which is 2 reflexes
1. Corneal reflex:
use apiece of cotton then suddenly attached it to the lateral corner
of eye. This reflex has the sensory by ophthalmic branch of 5th CN
and the motor part of 7th CN.
2. Jaw jerk:
not found normally if +ve mean Bilateral UMNL, it is done by
slight opening the mouth then put your index at the angle of jaw
14
then hit your finger by the hammer but in 45 degrees. This reflex is
supplied by C3
Sensory examination :
*Start up examination by using the special pin and move it as a
strip like line for each branch.
Facial nerve
The nerve has the function of ( expression, motor part of corneal
reflex, sensation of salivary and lacrimal gland, sensation of
anterior 2/3 of tongueand taste by chorda tympani branch).
The paralysis of the nerve called the Bell's palsy that occur as:
1-UMNL:
There is lesion above the nucleus and characterized by:
1. Hypertonia occur as Spasticity of the limb
15
2. There is very mild or no wasting of muscle.
3. Reflexes are brisk or exaggerated.
4. The upper part of face not involved because the forehead has the
dual nerve supply but the lower part will be affected.
5. plantar reflex is upgoing mean +ve Babiniski sign.
The causes may be CVA, Pyramidal system lesion.
2-LMNL:
This indicates the lesion in the anterior horn cells and the lesion
occur inside the nucleus, it is characterized by:
1. Weakness and wasting of muscles.
2. Fasciculation
3. hypotonic
4. Loss of the reflexes.
Causes may be :
*Poliomyelitis
*Warding Hoffman syndrome
*Diabetic neuropathy
*Alcohol and trauma
*Drugs as INH and vincristine and metronidazole
* Infectios as diphtheria and Leprosy.
* Guillian-Barre syndrome.
16
* Motor neuron dis.
•*Vitamin Bi and B12 deficiency.
* Amyloidosis.
The most common cause for Bell's palsy is idiopathic others may
be viral as mentioned above.
The effect of the UMNL is that the lower part of the face is more
obvious and deviation occur toward the healthy side.
The effect of the LMNL is that the upper and lower part will be
affected, there is loss of nasolabial fold on the affected side, and
deviation of mouth to the normal side occur, the patient can not
close the eyes properly, if the patient whistle there is leaking of the
air through the affected side , and there is increase the space
between the corner of mouth and the tongue of the affected side
when the patient open the mouth. Some time the patient will have
(Bell's Phenomena) in which the patient try to open the eyes but
the sclera is still appear and the eyeball go up and medially.
17
Examination of this nerve is done as the followings:
1) Ask the patient to elevate the eye brows and then look to the
creases in the forehead if lesion occur there is absence of these
creases (Frowning test).
2) Ask the patient to close both eyes firmly and then try to open
them by your hand to know the ability of closing against the
resistance.
3) Look to the nasolabial fold whether present or flat.
18
4) Ask the patient to show you his or her teeth as she or he
clinching.
5) Ask the patient to protrude the tongue then look to the angle
between the tongue and the corner of mouth whether increased or
not.
6) Ask to whistle.
7) Ask the patient to make the puffing of the mouth then touch the
cheeks for any air leaking or not.
8) Corneal reflex.
The Bell's palsy can be treated with
• prevent drying of the cornea by using artificial tear or
methylcellulose
19
• corticosteroid as prednisolone
• massaging and electrical stimulation of the nerve
• surgery as tarsorrhaphy and the facial-hypoglossal anastomosis
Vestibulo cochlear nerve
Has function of hearing and balance by cochlear and vestibular
part respectively.
Defect in vestibular part causing the vertigo, the defect in the
cochlear part causing the deafness which is 2 types:
1) conductive Deafness: as due to ear wax , fluid and
otosclerosis. The Rinne's test result ( BC>AC) , and the
Weber test result is positive on the affected side only.
2) Sensorineural deafness: as due to acoustic neuroma ,
fracture of pterygotemporal bone and injury to the nerve,
20
Rinne's test=AC>BC and Weber is +ve on the unaffected
side.
Not: Normally the AC ( Air conduction)>BC ( Bone conduction)
Examination is done as followings:
1) Roughly just by friction of the fingers near the ear bilaterally.
2) Rinne's test:
as we used the tuning fork and put it in front of the ear then put it
at the mastoid process ask the patient does it feel and hear same or
not.
3) Weber test:
as by using the tuning fork put it on the forehead ask the
patient hearing it normal and equal for both ear or not.
21
4) Calorie test: For vestibular branch
5) Rotation test: for vestibular branch
Glosso Pharyngeal nerve
Its function is elevation of larynx and supply the posterior 1/3 rd of
the tongue and supply parotid gland. It is examined with vagal
nerve.
22
Vagus nerve
It supplies the pharynx, larynx, heart, movement of palate and
viscera. The defect of these nerves make the patient to present
with:
*Nasal speech
*Nasal regurgitation
*Aspiration.
The causes may be unilateral as due to head injury and tumour or
bilateral as due to CVA ,MS, and bulbar and pseudobulbar palsy.
Examination is as followings:
1) Ask the patient to open the mouth and look whether the uvula is
deviated or not.
2) Ask the patient to say (Ahhh) then look to the soft palate
whether it is elevated or not.
3) Gag reflex: put tongue depressor on each side of tongue if
found mean it is good but may be absent in bulbar palsy.
4) Examination of posterior wall of pharynx by putting tongue
depressor on each side of tongue then pin prick of the wall ask
whether feeling is same or not.
5) Examination of posterior 1/3rd of toungue.
23
Spinal accessory nerve
The nerve supply the SCM and the Trapezius muscle.
Examination is as followings:
*Ask the patient to look to one side and then by your hand palpate
the SCM of opposite side and same for other side.
*Ask the patient to shrug the shoulders and then put both hand at
the patient's shoulder against the resistance for trapezius mescle.
Hypoglossal nerve
The nerve supply the muscles of tongue. If there is palsy of the
nerve will causing the deviation of the tongue to the opposite site
of the lesion and there is atrophy of the affected side with some
24
speech abnormalities as dysarthria and ataxia of tongue.
Examination is by asking the patient to open the mouth then look
for the symmetry, fasciculation , atrophy, abnormal movement as
ataxia or tremor.

26
Examination of Meningeal signs
These signs are important to exclude whether meningitis is found
or not.
These signs are 3 :
Neck stiffness:
Patient is lying in supine and then flex the neck feel whether there
is rigidity or not, you can put the head of the patient just beside the
bed to make the flexion easier.
Kernig's sign:
this done by flexion of hip and then extension of knee that causing
painful sensation in the Hamstring muscles.
Brudizinski's sign:
this done by flexion of the hip only that causing
27
involuntary flexion of neck or can be done by flexion of neck that
causing flexion of hip joint.
Motor system examination
Steps of the examination include the followings:
1-Inspection
Look for the followings:
1) Wasting of the muscles of both limbs:
In the upper limb especially look to the interossi muscles and
in the lower limb palpate the beside of the shaft of tibia and
then if the both sides between the tibial bone was same this
mean wasting of muscle so the bulging should be found
normally.
28
2) Fasciculation :
( it is the fibrillatory or wavy movement of group of muscles)
almost look to the axillary and deltoid region or to the medial
aspect of thigh
3) Any abnormal movements:
include the followings:
Tremor : Examine for flapping tremor also by extending the both
upper limbs then extend both wrists, close the eyes , then push the
hand of patient toward the patient for flapping.
Chorea : it is the abnormal restless involuntary movement more
at the big proximal joints as around shoulder.
Athetosis : slow sinusoidal movement in the distal joints as in the
hand.
Hemiballismus : sudden violent movement due to sub thalamic
lesion.
4) Abnormal posture which is occurring as sustained movement
what is called Dystonia or the wrist drop....
29
5) Look for any car of previous operation as for tendon
replacement.
2-Tone:
We have 3 degree of tone:
*Normal tone
*Hypotonia: as occur in cerebellar diseas and in peripheral
neuropathy.
*Hypertonia: As occur in 2 forms:
• Rigidity mean resistance will be continue through out the
movement and occur due to lesion in basal ganglia and occur due
to extra pyramidal lesion (Remember there is no special structure
or organ in body by this name only to differentiate it from the
pyramidal tract) and rigidity has 2 main forms:
A. cogwheel type-as occur at wrist joint and can be tested by
catching the hand of patient at the wrist joint then by other hand do
the circular movement of the hand it fond intermittent resistance.
Can be found in CVA.
30
B. lead pipe Type -when you put the hand or forearm in a position
it will stay at that position as found in Dementia.
• Spasticity: mean there is resistance at the start of movement but
later become normal and no resistance, occur due to cortico spinal
tract lesion. Can be found in form of clasp-knife as in CVA.
Best way to examine the tone is by ( Sudden Fast Unexpected
movement) , as you handle the forearm at the elbow then by other
hand catch the hand of patient then move it to right and left then
suddenly move it toward the patient
and do the same movement at the lower limb.
To examine the clonus which is sustained continuous movement is
by catching the ankle and then move the foot toward the patient
many times then sudden move toward the patient.
31
3-Power:
Remember the 5 degrees of the power:
G0 = there is no movement at all by asking the patient to move and
raise the hand can not do it.
G 1 = there is flicker movement, that the patient will only do some
fine movement at the fingers only
32
G 2 = movement at bed side, as the patient wi1l move the hand at
the bed to right and left without elevating it.
G3= there is movement against the gravity as the patient will raise
the hand for a while.
G 4 = there is movement against the resistance for certain limit as
the patient will raise the hand and can raise it against your pressure
on the hand of patient.
G 5 = full normal movement.
The pyramidal weakness may occur in 2 forms:
* Central = here ther is paraplegia or hemiplegia and the grade of
power not equal around the affected joints.
*Peripheral weakness = there is bilateral symmetrical
involvement in UL or LL or both, and there is equal grades of
power around the joints.
CST play very important role and may be affected in case of
stroke, SOL, hematoma.
Functions include:
A- Anti gravity movements in the Upper limb:
1) Shoulder abduction
33
2) Elbow extension
3) Wrist extention
4) Fingers extension
B- Anti gravity movements at the Lower limb:
1) Hip flexion
2) Knee flexion
3) Dorsiflexion of foot
4) Eversion of foot
So start the examination from proximal to distal because the
myopathy is almost proximal except in case of Myotonia
Dystrophica which is distal.
Upper Limb:
Tone Examination includes 6 muscle groups:
1) Deltoid= examine against the abduction of shoulder.
2) Latissimus dorsi = examine against the adduction of shoulder.
3) Biceps = examine against the flexion of the elbow joint.
4) Triceps = examine against the extension of elbow.
5) Forearm muscles = as examine against the supination and
pronation of forearm.
34
6) Hand muscles = examined by ask the patient to grip your hand
strongly, and then against the extension ,flexion, abduction and
adduction of fingers.
Lower Limb:
Examination includes:
1) Examine against the abduction, adduction, extension( both of
your hands under the thigh of patient-glutei muscles) , flexion
(both of your hands on the patella of patient- iliopsoas muscle) of
hip joint.
2) Examine against the extension( quadriceps) and
flexion( Quadriceps Femoris) of knee joint.
3) Examine against the dorsi flexion, the plantar flexion, eversion
and inversion of the ankle joint.
4) Examine against the flexion and extension of toes.
Note :
•Monoplegia =paralysis of one limb as right hand
•Hemiplegia = paralysis of half of the body as right UL and LL •.
•Quadriplegia = paralysis of all limbs.
•Paraplegia = as paralysis of both LLs.
35
36
4-Reflexes :
Before doing the reflex examination following points are
important:
*Remember the aim is to detect the mild asymmetry in reflexes
and not the gross obvious abnormalities.
*Almost start distally.
*Do complete relaxation of the patient before the examination
*Almost handle the hammer from the terminal part.
*Not hit the joint more than 2 times as the reflex will be
diminished by it self.
*Do the reflexes bilaterally and symmetrically as supinator on both
sides then the other reflexes.
*Elevate the hammer actively then let it hit the joint passively.
*Never say there is no reflex or diminished unless you do the re-
enforcement as by clinching the teeth or pulling the both hands
together.
37
*L5 not share in any reflex.
*The most powerful reflex is knee reflex.
2 main groups of reflexes:
Deep Reflexes —Monosynaptic reflexes
A- UL ( Upeer Limb): include 3 reflexes:
Supinator Reflex:
By catching the fingers of the patient then hit about one finger or
one and half from the wrist joint by the hammer. Supply by C5, 6.
38
Biceps Reflex:
Supply by C5,6 and done by flexing the elbow and put it on the
abdomen of patient then feel the biceps tendon and put your thumb
on it and hit your thumb with the hammer.
Triceps Reflex :
Supply by C7, done by flexing the elbow and put it on the
abdomen of patient then put one of your hand under the elbow
joint then hit by hammer about one finger or one and half from the
olecranon process. Muscle is triceps muscle and the nerve is radial
nerve.
39
B-LL ( Lowe Limb): include 2 reflexes:
Knee reflex :
Supply by L3,4 and done by flexing the knee then put one of your
hand under the knee and by other hit the space between the head of
tibia and the lower part of patella. Muscle is quadriceps muscle,
nerve is femoral nerve.
Ankle reflex :
Supply by S1, muscle is Gastrocnemius muscle and the nerve is
posterior tibial nerve, is done by mild flexion of foot just do it on
the bed no need put that limb on the other one then hit the Achilles
tendon and watch the calf muscle.
40
Superficial reflexes- Polysnaptict reflexes
2 main reflexes:
Abdominal reflex:
No specific supply some say it is T7,12, the muscles are rectus
abdominis muscles .
Abdominal reflex is absent in case of hemiplegia that the condition
will be confirmed by plantar up going, in case of obese and
multipara female.
Plantar Reflex :
Is done on the outer border of the foot and should be done
painfully and look to the big toe at first, the result is either:
*Big toe not move at all= pathological
*Big toe going up and down= called equivocal again is
pathological.
*Big toe is up going =severe pathological
*Big toe is down going = it is normal.
41
Note : Remember the babiniski sign is +ve but normal in (neonate
and epilepticpatient).
In male also we have cremastric reflex (L1) by scratching the inner
aspect of the thigh in the creases for example.
And also the anal reflex that may be disappear in case of conus
medullaris lesion.
Note :
Hoffman sign is done by extending the wrist then scratch the tip of
middle finger then if +ve there is flexion of thumb and other
fingers.
42
Co-ordination Examination
Also called cerebellar examination, and helpful for parkinsonism ,
include the following steps:
1) By inspection look to the eyes for the nystagmus (irregular
involuntary movements of eyes) , then test the speech of the
patient for the dysarthria, ask to protrude the tongue for the
ataxia, or intension tremor, hypotonia and decrease the
reflexes.
2) Finger-nose test :
as stand infront of the patient at first time explain for patient to put
the index finger on his or her nose and then on the examiner's
finger, then do it while the patient closed his or her eyes. The faster
touching your fingers the better the result, the result is either:
A.Intention tremor ( dysmetria) , if abnormal or irregular
touching of target found.
B.Dysnergia : total incoordination and clumsiness.
C.Post point: can not identify the target.
43
3) Rapid-alternating test:
touching the other hand by palmar and dorsal surface of the other
hand, called Dysdiadochokinesia.
4) Heel-shin test:
ask the patient to make the friction of the heel of one foot on the
tibial shaft on the other limb.
44
5) Romberg's sign:
ask the patient to stand and then do full abduction and move the
upper limb away from him self then close the eyes watch whether
falling occur or not.
6) Then examine for gait by asking the patient to move on the
straight line as if she or he measuring the distance by using the
feet.
45
Sensory Examination
Superficial sensation: half of touch, pain and temperature.
Deep sensation: Half of touch, vibration.
Examination Steps:
1) Start from the both sides of face by pin prick or using a piece
of cotton wool, then proceed to the volar surface of the upper
and lower limb and all other areas, then ask the patient do
you feel it same on both side or not?
2) For vibration use the tuning fork: by asking to close the eyes
and whether feeling same or not put it on the following areas:
*Forehead
*Patella
46
*Medial malleolus.
*Tuberosity of big toe.
3) Testing the Proprioception: this by asking to cloth eyes then
move the big toe 6 times upward and downward then ask the
patient to tell you the direction of the movement.
47
Some Definition :
AGNOSIA: The inability to recognize the significance of sensory
stimuli, due to parietal lobe lesion. We have visual and olfactory
agnosia.
APRAXIA: inability to perform the purposeful movement in
absence of paralysis.
AGRAPHIA: inability to write.
ALEXIA : inability to read.
DYSCALGUL1A: inability to perform the mathematical
procedures.
Higher cerebral function Examination
The stepwise are:
1) Level of consciousness: either:
Fully conscious.
Coma : the complete loss of awareness to the environment even
when the patient is extremely stimulated.
Drowsy : inability to sustain the wakefulness without the external
stimuli.
Stupor : aroused only by vigorous and repeated stimuli only.
48
The examination is as followings:
A- Do quick general examinations for any head trauma then say I
will take the vital signs as for high fever and type of respiration.
B- Do verbal command: ask the patient to show you 2

III. Conductive Dysphasia.: the patient have abnormality in
repetition.
IV. Global Dysphasia: include both receptive and expressive
