Background The symptom of tongue deviation is observed in a stroke or transient ischemic attack. Nevertheless, there is much room for the interpretation of the tongue deviation test. The crucial factor is the lack of an effective quantification method of tongue deviation. If we can quantify the features of the tongue deviation and scientifically verify the relationship between the deviation angle and a stroke, the information provided by the tongue will be helpful in recognizing a warning of a stroke.

Methods In this study, a quantification method of the tongue deviation angle was proposed for the first time to characterize stroke patients. We captured the tongue images of stroke patients (15 males and 10 females, ranging between 55 and 82 years of age); transient ischemic attack (TIA) patients (16 males and 9 females, ranging between 53 and 79 years of age); and normal subjects (14 males and 11 females, ranging between 52 and 80 years of age) to analyze whether the method is effective.
In addition, we used the receiver operating characteristic curve (ROC) for the sensitivity analysis, and determined the threshold value of the tongue deviation angle for the warning sign of a stroke. Results The means and standard deviations of the tongue deviation angles of the stroke, TIA, and normal groups were: 6.9 ± 3.1, 4.9 ± 2.1 and 1.4 ± 0.8 degrees, respectively. Analyzed by the unpaired Student’s t-test, the p-value between the stroke group and the TIA group was 0.015 (>0.01), indicating no significant difference in the tongue deviation angle. The p-values between the stroke group and the normal group, as well as between the TIA group and the normal group were both less than 0.01. These results show the significant differences in the tongue deviation angle between the patient groups (stroke and TIA patients) and the normal group. These results also imply that the tongue deviation angle can effectively identify the patient group (stroke and TIA patients) and the normal group.
With respect to the visual examination, 40% and 32% of stroke patients, 24% and 16% of TIA patients, and 4% and 0% of normal subjects were found to have tongue deviations when physicians “A” and “B” examined them. The variation showed the essentiality of the quantification method in a clinical setting. In the receiver operating characteristic curve (ROC), the Area Under Curve (AUC, = 0.96) indicates good discrimination. The tongue deviation angle more than the optimum threshold value (= 3.2°) predicts a risk of stroke. Introduction Stroke, a cerebral vascular incident, is mainly caused by abnormal blood vessels in the brain. According to the statistical results of the World Health Organization (WHO), stroke remains the worldwide second leading cause of death.
It is estimated that one in five stroke survivors will have the chance of a second stroke within five years. Thus, it has a high recurrence rate, and recurrence can bring about disability and dementia, often leading to a heavy burden for an individual household, a community, and ultimately society in general. This reminds us how important it is to prevent, recognize and monitor the stroke subject. A stroke, often occurring suddenly, happens for two main reasons. Firstly, a hemorrhagic stroke results from a weakened vessel that ruptures and bleeds into the surrounding brain. About 20% of strokes are hemorrhagic. Secondly, and more commonly, an ischemic stroke occurs when an artery in the brain becomes blocked.
Throughout the centuries, surnames in every country have continued to 'develop' often leading to astonishing variants of the original spelling. Premium leecher. The musical composer James Leach (1762 - 1798), was a member of the King's Band and was known for his compositions for stringed instruments, whilst another notable namebearer was William Leighton Leitch (1804 - 1883). He was drawing master to Queen Victoria and the royal family for over twenty years. This was dated 1279, in the 'Hundred Rolls of Oxfordshire', during the reign of King Edward 1st of England, 1272 - 1307. The first recorded spelling of the family name is believed to be that of Edmund le Leche.
About 80% of strokes are ischemic strokes. If a major artery to the brain is blocked, part of the brain tissue can die from lack of oxygen carried in the blood. When brain tissue dies, the effects on the body will depend on which body functions that part of the brain controls. Some of the effects on the body are quite well known and are commonly recognized as the result of a stroke.
A stroke will produce changes in the body and affect various functions, including the sensory function, action function, language ability, the swallowing function, etc. For instance, paralysis of the right side of the body (right-sided stroke) will be caused by damage to the left half of the brain. In most patients, inability to speak will also be due to damage to the left side of the brain, because the left side of the brain controls speech. A “mini-stroke,” also called a “transient ischemic attack” (TIA), causes a reversible neurologic deficit. The damaged area can be so small that the blood supply to other parts of the brain can compensate, and a full recovery takes place.
