The document summarizes the clinical manifestations of strokes. It describes the differences between thrombotic, embolic, and hemorrhagic strokes and how their symptoms vary based on the location and size of the brain lesion. It then provides details on specific types of strokes like TIAs, thromboses, embolisms, and aneurysms. Finally, it outlines the general signs and symptoms that can result from strokes like sensory and motor deficits, reflex changes, apraxia, aphasia, and cognitive impairments.

1. STROKE CLINICAL MANIFESTATION
- NITHIN NAIR

2. CLINICAL MANIFESTATION
The focal neurological deficit resulting from a
stroke, whether embolic, thrombotic, or
hemorrhagic, is a reflection of size and location of
the lesion and the amount of collateral blood
flow.
Clinical syndromes resulting from occlusion or
haemorrhage in the cerebral circulation vary from
partial to complete.
Ischemic stroke account for (80%), hemorrhagic
stroke account for (20%) of strokes.

3. Clinical picture....
THROMBOSIS TIA EMBOLISM
Uneven progression
Onset develops within
minutes or hours or days
(thrombus in evolution)
60% occur during
sleep- patient unaware of
problem, rises and falls
to floor
No headache or in
mild form
Comorbid factors –
hypertension, diabetes,
or vascular diseases.
Linked to
atherosclerotic
thrombosis.
Preceded or
accompanied by stroke
Last 2-30 minutes (less
than 24 hours)
Normal neurological
findings between attacks
If transient symptoms
persist on awakening,
may indicate future
stroke.
Occurs rapidly
There are no warnings
MCA infarct (common)
Headache
Often a manifestation of
heart diseases, including
atrial fibrillation and MI
As embolus passes
through artery, client may
have neurological defecits
that resolve as embolus
breaks and passes into
small artery

4. Clinical picture....
HYPERTENSIVE HEMORRHAGE RUPTURED SACCULAR ANEURYSM
Severe headache
Vomiting at onset
Blood pressure > 170/90 (normally
essential hypertension)
Abrupt onset
Gradually evolves over hours or
days according to speed of bleeding
No recurrence of bleeding
Rapid improvement (not usual as
hemorrhaged blood absorbs slowly.)
Asymptomatic before rupture.
With rupture, blood spills under
high pressure into sub arachnoid
space.
Excruciating headache with/without
loss of consciousness
Decerebrate rigidity with coma
If severe – persistent deep coma,
respiratory arrest, circulatory collapse
leading to death (within 5 min)
If mild – consciousness regained
within hours then confusion, amnesia,
headache, stiff neck, drowsiness.

5. GENERAL SIGNS AND SYMPTOMS
• Sensory : Tingling, numbness or decreased
sensation (cortical sensations) on the affected
side of the body.
• Crossed anesthesia (Ipsilateral facial
impairments with contralateral trunk and limb
involvement.)

6. General signs and symptoms.....

• Unable to generate force to initiate and
control movement.
• UE > LE (affection)
• Distal muscles > Proximal muscles ( strength
deficits)
• Selective loss of type II fast-twitch fibres and
increase in percentage of type I fibres.

7. General signs and symptoms.....
• Motor : Immediately after the onset of stroke, there is
a stage of cerebral shock with flaccidity and areflexia.
Gradually replaced by development of spasticity,
hyperreflexia and synergy pattern.

9. General signs and symptoms.....
• An inspection of the synergy components
reveals that following muscles do no take part
in either of the synergies.
• Latissimus dorsi
• Teres major
• Serratus anterior
• Wrist and finger extensors
• Ankle evertors

10. General signs and symptoms.....
• Reflexes : Flaccidity all reflexes are
suppressed or absent.
• Spasticity Deep tendon reflexes become
hyperactive, presence of clonus, plantar reflexes
show babinski sign positive
• Release of primitive reflexes : ATNR (most
common)
• Associated reactions : Tonic postural reactions in
muscle. For eg: Vigorous contraction of elbow flexors
(stronger UE) Flexion of hemiparetic elbow

11. General signs and symptoms.....
• Altered Co-ordination : Proprioceptive losses
sensory ataxia.
• Strokes affecting cerebellum cerebellar
ataxia.
• Basal ganglia involvement bradykinesia or
involuntary movements.

12. General signs and symptoms.....
• Potural control and Balance: Reactive postural control
and anticipatory postural control affected.
• Unable to maintain balance in sitting or standing or to
move in a weightbearing posture without loss of
balance.
• Disruptions in central sensorimotor processing.
• Sitting /standing : asymmetry (weight shifted towards
affected side)
• Postural sway in standing.
• Delays in onset of motor activity, abnormal timing and
sequencing of muscle activity and abnormal co-
contraction disorganization of postural synergies.

13. General signs and symptoms.....

anxious and have a negative attitude towards life,
cautios and insecure
• Right hemisphere lesion – euphoric, over-
confident, impulsive, over estimate their capacity,
denial of being disabled.

libido, erectile or lubrication, orgasm or
ejaculation. It could be due to depressed state
or sensorimotor dysfunction.

21. Secondary manifestations
• Psychological dysfunction : Depression, social
withdrawal, anxiety, insomnia, emotional
liability, aggressiveness, verbal abusing, over
dependancy)
• Deep Vein Thrombosis : ( occurs in hemiplegia
due to immobilization)
• Cardiac and Respiratory deconditioning:
occurs due to decreased physical activity.
Endurance level is drastically reduced.

22. Secondary manifestations
