MAYO HOSPITAL LAHORE
• UPPER MOTOR NEURONS (UMN) start from
cerebral cortex, passes through internal capsule,
corticospinal tracts, and ends at cranial nerve nuclei
in brain stem or anterior horn cells of spinal cord at
different levels. The axons of upper motor neurons
are contained within the pyramidal system, which is
composed of the corticospinal (pyramidal) and
corticobulbar tracts.
• LOWER MOTOR NEURONS (LMN) start from nuclei
of cranial nerves or anterior horn cells of spinal cord,
extend through cranial /spinal nerves and ends at
motor end plate of concerned muscle.

UPPER MOTOR NEURONS LESION
(UMNL)
.
Pyramidal Drift Of An Upper
Limb
Normally, the outstretched upper limbs are
held symmetrically, when the eyes are closed.
With a pyramidal lesion, when both upper
limbs are held outstretched, palms
uppermost, the affected limb drifts
downwards and medially. The forearm tends
to pronate and the fingers flex slightly. This
sign is often first to emerge, sometimes
before weakness and/or reflex changes
become apparent.
Pyramidal Drift Of An Upper
Limb
Weakness And Loss Of Skilled
Movement
 A unilateral pyramidal lesion above the
decussation in the medulla causes weakness of
the opposite limbs.
 When acute and complete, this weakness will be
immediate and total, a hemiplegia, e.g.
following an internal capsule infarct.
 With slowly progressive lesions (e.g. a
hemisphere glioma) a characteristic pattern of
weakness emerges – a hemiparesis.
 There is also loss of skilled movement – fine
finger and toe control diminishes.
Changes In Tone And Tendon
Reflexes
 An acute lesion of one pyramidal tract (e.g.
internal capsule stroke) causes initially FLACCID
paralysis with loss of tendon reflexes.
 Increase in tone follows, usually within several
days due to loss of inhibitory effects of the
corticospinal pathways and an increase in
spinal reflex activity.
 SPASTICITY is characterized by sudden
changing resistance to passive movement – the
clasp-knife effect.
 Relevant TENDON REFLEXES become
exaggerated;
 CLONUS may emerge.
Changes In Superficial Reflexes
Abdominal (and cremasteric) reflexes are
abolished on the side affected.
The Babinski sign.
Patterns of UMN disorders
There are three main patterns:
 HEMIPARESIS means weakness of the limbs on
one side; it is usually caused by a lesion in
the brain and occasionally in the cord.
 PARAPARESIS means weakness of both lower
limbs and usually diagnostic of a cord lesion;
bilateral brain lesions occasionally cause
paraparesis.
 TETRAPARESIS (syn. quadriparesis) means
weakness of four limbs.
Extrapyramidal system
The extrapyramidal system is a general term for
BASAL GANGLIA motor systems, i.e. corpus striatum (caudate
nucleus + globus pallidus + putamen), subthalamic nucleus,
substantia nigra and parts of the thalamus. In basal ganglia/
extrapyramidal disorders, two features (either or both)
become apparent, in limbs and axial muscles:
 Reduction in speed (bradykinesia, meaning slow
movement) or akinesia (no movement), with muscle
rigidity
 Involuntary movements (e.g. tremor, chorea,
hemiballismus, athetosis, dystonia).
Extrapyramidal system
• Extrapyramidal disorders are classified broadly into:
Akinetic-rigid Syndromes where poverty
of movement predominates
Dyskinesias where there are involuntary
movements.
• The most common extrapyramidal disorder is
Parkinson’s disease.

Case Scenario
• An 83-year-old right-handed woman was eating
dinner when she suddenly slumped to the right and
her speech became slurred and nonfluent. Her
vascular risk factors were hypertension and
dyslipidemia, and the only other past medical
history of interest was long-term hypothyroidism
and a curative mastectomy for breast cancer. The
patient was on two antihypertensive medications
and a statin, and was not receiving any antiplatelet
medication. Her husband immediately called the
emergency medical services.
Case Scenario
On Examination Pulse is 84/min (regular), BP:
180/105 mm Hg.
Angle of mouth is deviated towards left (UMN type
Right 7th CN)
Tone is decreased in right upper and lower limb,
Power is 2/5 in right right upper and lower limb,
Reflexex are absent in right right upper and lower
limb.
Right Planter is upgoing.
Tone, power, reflexes are normal on left side with
downgoing planter
What is your Diagnosis????
STROKE
This patient has had STROKE causing
Right sided uncrossed Hemiplegia with
UMN type Facial Nerve Palsy which can
be caused by a vascular event such as
thrombosis, embolism or hemorrhage or
by neaplasm of brain (aetiology). The
patient is limited by hemiplegia
(functional status)
Stroke
DEFINITION: Stroke is defined as a
syndrome of rapid onset of cerebral
deficit (usually focal) lasting >24 h or
leading to death, with no cause
apparent other than a vascular one.
Stroke
Ischaemic stroke/infarction (80%)
 Thrombotic
 Cardio-embolic
 Large artery stenosis
 Small vessel disease
 Hypoperfusion
Haemorrhagic stroke (17%)
 Intracerebral hemorrhage (12%)
 Subarachnoid hemorrhage (5%)
Other (3%), e.g. arterial dissection, venous sinus
thrombosis, vasculitis
Types of Stroke
Depending upon the rate of developing and reversibility, stroke can be
of following types:
 Transient Ischemic Attack (TIA): means a brief episode of
neurological dysfunction due to temporary focal cerebral
or retinal ischemia without infarction, e.g. a weak limb,
aphasia or loss of vision, usually lasting seconds or
minutes with complete recovery.
 Stroke-in-Evolution: If neurological deficit increases by
step wise progression or there is slow uninterrupted
progression, it is called stroke-in-evolution. It may take 12 weeks to complete
 Complete Stroke: It means complete hemiplegia
 RIND (Reversible Ischemic Neurological Deficit): It is a term that is
not widely used anymore. It means a stroke that the patient was
able to fully recover from within a few weeks.
Types of Stroke
Depending upon the blood supply of affected area of
brain, stroke can be of following types:
 ANTERIOR CIRCULATION STROKE:
Carotid system
 POSTERIOR CIRCULATION STROKE:
Vertebrobasilar system
Risk Factor For Ischemic Stroke

SPINAL CORD.
Brown-Sequard syndrome (BSS) is a rare
neurological condition characterized by a lesion
in the spinal cord which results in weakness or
paralysis (hemiparaplegia) on one side of the
body and a loss of sensation (hemianesthesia) on
the opposite side.
Causes:
• Trauma
• Non-traumatic: Tumor (primary or metastatic),
Multiple sclerosis, Disk herniation, Epidural
hematoma, Vertebral artery dissection,
Transverse myelitis, etc

MIDDLE CEREBRAL ARTERY
• Supplies lateral surface of frontal,frontal, perital and

• Most of the motor and sensory cortex Ecxept the part
on medial side and control lower limb, internal capsule
Total Occlusion:
• Uncrossed hemiplegia
• Hemianesthesia
• Global Dysphasia
• Homonymous hemianopia
• Apraxia, Agnosia
Partial occlusion:
• Any of the above features.
• Lower limb is either not or minimally involved
ANTERIOR CEREBRAL ARTERY

control lower limb
• Soon its origin it gives a penetrating branch
(Heubner’s artery) which supply internal capsule
(containing fibers of upper limb and face)
Occlusion at the origin:
Features are similar to total occlusion of MCB
Occlusion of Heubner’s artery
:
• Weakness of upper limb and face

LATERAL MEDULLARY SYNDROME
• Also called posterior inferior cerebellar artery (PICA)
thrombosis and Wallenberg’s syndrome)
• Acommon example of brainstem infarction presenting as
acute vertigo with cerebellar and other signs. It follows
• Thromboembolism in the PICA or its branches, vertebral
artery thromboembolism or dissection.
• Features depend on the precise structures damaged.
MEDIAL MEDULLARY SYNDROME
• Characterized by a set of clinical features resulting from
occlusion of the anterior spinal artery. This results in the
infarction of medial part of the medulla oblongata.
Investigations - STROKE
The purpose of investigations in stroke is:
• To confirm the clinical diagnosis and
distinguish between hemorrhagic
and thromboembolic infarction;
• To look for underlying causes and to
direct therapy;
• To exclude other causes, e.g.
tumour.
• Sources of embolus should be
sought
Investigations of Stroke
Brain Computed Tomography (CT)
Scan
Magnetic resonance imaging (MRI)
Computed Tomography Arteriogram
and Magnetic Resonance Arteriogram:
Aneurysm, AV malformation
Carotid Ultrasound
ECG and Echocardiography
Lumber Puncture: Subarachnoid
Hemorrhage
Investigations - STROKE
 Routine bloods (for ESR, polycythaemia,
infection, vasculitis, thrombophilia, syphilitic
serology, clotting studies, autoantibodies)
 Blood Sugar Level
 Fasting Lipid profile
 Chest X-ray
 ECG and Echocardiography
 Carotid Doppler studies
 Lumber Puncture: Subarachnoid Hemorrhage
Investigations - STROKE
• Imaging in Acute Stroke.
• Non-contrast CT:
will demonstrate haemorrhage immediately but
cerebral infarction is often not detected or only
subtle changes are seen initially.
