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.

OBJETIVO: Utilizando o QEEG TQ-7, este estudo objetivou avaliar a associação dos sintomas de ansiedade, insegurança, medo, pânico e/ou fobia com a categoria de temporais quentes definidos como Beta (15-23 Hz) >17% e Beta-Alta (23-38 Hz) >10% em T3 e T4.

MéTODOS: Foram avaliados 543 pacientes de ambos os gêneros na faixa etária de 16-59 anos, divididos: Controle (sem temporais quentes: n=274) Grupo estudado (com temporais quentes: n=269). Foi utilizado o teste qui-quadrado (p-valor ≤0.05).

RESULTADOS: Houve associação significativa (p-valor <0.001) entre os sintomas relacionados à ativação da amigdala, expressos nos temporais (Beta >17% e Beta-Alta >10%). (Ansiedade, T3=89,6% - T4=88,8%; T3=92,6% - T4=93,3%), (Medo, T3=80,7% - T4=84,4%; T3=82,9% - T4=95,9%), (Insegurança, T3=82,2% - T4=81,4%; T3=69,5% - T4=97,8%), (Pânico, T3=52.4% - T4=72.5%; T3=90.3% - T4=74.0%), (Fobia, T3=17,5% - T4=22,7%; T3=19,7% - T4=27,1%), quando comparados aos respectivos controles (Beta controle, T3=8,4%, 10,2%, 21,2%, 1,1%, 0,4% e T4=11,3%, 4,4%, 23,0%, 2,6%, 1,1%) e (Beta-Alta Controle, T3=4,0%, 6,9%, 6,2%, 0,4%, 0,0%; T4=17,5%, 6,2%, 3,3%, 4,0%, 0,7%).

CONCLUSãO: Ansiedade, insegurança, medo, pânico e fobia são observados no QEEG, quando Beta >17% e Beta-Alta >10% em T3 e T4.
