Abstract
Stress is a response in which an individual wants to have more control over a situation. A constant state of stress is called anxiety. Some patients deny symptoms. An instrument can help arrive at a diagnosis.Objective:Using TQ-7 QEEG, this study aimed to evaluate the association of symptoms of anxiety, insecurity, fear, panic and phobia with hot temporals defined as Beta (15-23 Hz) >17% and High-Beta waves (23-38 Hz) >10% at T3 and T4.Methods:Five hundred and forty-three patients of both genders with ages ranging from 16-59 years were evaluated, divided into two groups: Control (without hot temporals: n=274) and Case Group (with hot temporals: n=269). The Chi-square test was used (p-values ≤0.05).Results:There was a significant association (p-value <0.001) between the symptoms related to amygdala activation, expressed in the temporals (Beta >17% and High-Beta >10%). (Anxiety, T3=89.6% - T4=88.8%; T3=92.6% - T4=93.3%), (Fear, T3=80.7% - T4=84.4%; T3=82.9% - T4=95.9%), (Insecurity, T3=82.2% - T4=81.4%; T3=69.5% - T4=97.8%), (Panic, T3=52.4 - T4=72.5%; T3=90.3% - T4=74.0%), (Phobia, T3=17.5% - T4=22.7%; T3=19.7% - T4=27.1%), when compared to the respective controls (Beta control, T3=8.4%, 10.2%, 21.2%, 1.1%, 0.4% and T4=11.3%, 4.4%, 23.0%, 2.6%, 1.1%) (High-Beta control, T3=4.0%, 6.9%, 6.2%, 0.4%, 0.0% and T4=17.5%, 6.2%, 3.3%, 4.0%, 0.7%).Conclusion:Anxiety, insecurity, fear, panic and phobia are observed by QEEG when the levels of total Beta >17% and High-Beta waves >10% at T3 and T4.

The TQ-7 is an evaluation method called Trainers’ quantitative electroencephalography (QEEG), which is in version 7,19 a component of The Learning Curve (TLC) technique, based on a protocol of 6 categories
Summary
Some factors have been listed as having relevant roles in the etiology of pathological anxiety. These include dissatisfaction at work,[5] a feeling of restlessness and stressful environments at home or work[6] and, above all, repetitive thoughts such as the habit of complaining (in the sense of lamentation),[7] over-analyzing, criticizing excessively, continuously judging and always thinking about the future and the past.[8,9]. When one thinks of measuring anxiety from the physiological point of view, some professionals do so by adrenal response controlled by the autonomic nervous system (sympathetic and parasympathetic). This study aimed to demonstrate that there is an expected pattern that identifies anxiety through brain electrical activity using quantitative electroencephalography (QEEG), which can help physicians and other healthcare professionals diagnose subjects and, to choose the best treatment
