Transitory ischemic attacks (TIAs), commonly referred to as mini-strokes, are brief episodes of neurological dysfunction resulting from a temporary disruption in the blood supply to parts of the brain, spinal cord, or retina. Unlike strokes, the symptoms of TIAs are temporary and usually resolve within 24 hours without causing permanent brain damage. However, TIAs are important warning signs of potential future strokes and thus require immediate medical evaluation to prevent more serious cerebrovascular events.
Traditional Chinese Medicine (TCM) approaches transitory ischemic attacks as indicators of underlying imbalances in the body's vital energies, particularly the flow of Qi and Blood. TCM theory suggests that TIAs result from obstructions or stagnations within the meridians that supply the brain. Identifying the specific disharmony—be it due to Blood Stasis, Qi Stagnation, or internal Wind—is crucial for effective treatment. TCM treatments aim to restore harmony and improve circulation, addressing both the symptoms and the root causes of TIAs.

Diagnostic signs
Wiry (Xian), Fine (Xi), Rapid (Shu)
The tongue body is red, reflecting Yin Deficiency with Heat. The most diagnostically significant features are stiffness, trembling, or deviation of the tongue body, all of which directly reflect Internal Wind agitating the channels. The tongue may deviate to one side, especially in more severe presentations approaching wind-stroke. The coating is often thin and yellow, or may be scanty or peeled in areas where Yin Deficiency is pronounced. In cases where Phlegm complicates the picture, the coating may become greasy or sticky. The sides of the tongue may appear redder than the centre, reflecting Liver Heat.
