Stroke (Cerebrovascular Accident) Introduction
Stroke
is a focal neurological deficit due to a vascular lesion resulting from
intracerebral hemorrhage (20%) and ischemic diseases (thrombosis, embolism, or
vascular insufficiency), which is most common reason (80%).
Thrombosis is the most common cause of stroke in middle-aged and elderly,
among whom there is a higher incidence of atherosclerosis, diabetes, and
hypertension. Thrombosis causes
ischemia in brain tissue supplied by the affected vessel as well as congestion
and edema. Hemorrhage results from
chronic hypertension or aneurysms, which cause sudden rupture of a cerebral
artery. The rupture diminishes
blood supply to the area served by this artery and the hematoma further
compresses neural tissue. Thrombosis
the onset usually occurs more gradually -- over minutes to hours; on rare
occasions it progresses over days to weeks. The symptoms for an ischemic stroke
are extremely variable depending on the area of the brain that has been
affected. The most common symptom is weakness or paralysis of one side of the
body or the other. There may be partial or complete loss of voluntary movement
of and/or sensation in a leg and/or arm. A stroke can result in speech problems
and weak muscles of the face, which can cause drooling. Numbness or tingling is
very common. Other symptoms include dizziness, vomiting, loss of muscle tone,
major seizures, and possibly coma. Hemorrhage typically begin very suddenly and
evolve over several hours and include headache, nausea and vomiting, and altered
mental states. When the hemorrhage is a subarachnoid type, warning signs (abrupt
headaches, nausea and vomiting, sensitivity to light, and various neurologic
abnormalities) can occur from the leaky blood vessel a few days to a month
before the aneurysm fully develops and ruptures. When the aneurysm ruptures, the
stroke victim may experience a terrible headache, neck stiffness, vomiting,
confusion, and altered states of consciousness. The eyes may become fixed in one
direction or lose vision. Stupor, rigidity, and coma can result. Diagnosis of
stroke is based on observation of clinical features, a history of risk factors,
and results of diagnostic test, such as CT, MRI and lumber puncture, etc. TCM etiology and Pathology In TCM, both of hemorrhage and ischemic
diseases is diagnosed as Zhong Feng (Wind stroking) and the treatments are
similar, therefore they are discussed together. In the acute stage, based on the symptoms, it can be divided
two types: Zhong Zang Fu (wind attacking visceral) and Zhong Jing Luo (wind
attacking channels and collaterals), the former is severe, often loss
consciousness, the later is not serious, perhaps hemiplegia but not loss
consciousness. 1. Emotion changes 2. Diet disorders 3. Deficient constitutions 4. Weather changes In the acute or middle-aged patients,
the illness often is excessive and in the chronic or senior often is deficient
with excessive syndromes. The
excessive may be fire, internal wind that is hyperactivity liver yang, phlegm or
blood stasis. The deficient may be
qi or yin deficiency. Blood stasis
is basic pathological change in the late stage, because any reason finally
causes blood circulation disorder. TCM
differentiation and treatment 1. Acute stage 1. 1. Wind-stroke attacking the visceral 1.1.1. Obstructive

collaterals Compared with wind attacking the organs, this
type is mild. The main symptoms are
hemiplegia, or limbs numbness and weak, or slurring speaking, etc, but not loss
consciousness, most is thrombosis, some hemorrhage. 1.2.1 Hyperactivity yang with yin deficiency Clinical manifestation: Often headache, or

the clinic, those two stages diagnosis and treatment are similar. The
pathological changes mainly are two: long term illness leading qi deficiency,
showed as body weak and fatigue, and blood stasis in the channels, manifested as
hemiplegia and other function disability, also might be phlegm blocking or liver
yang hyperactivity or kidney deficiency. 2.1
Hemiplegia Clinical
manifestation: Hemiplegia, numbness or weak of limbs, deviated tongue, slurring
