Electroclinical Correlation of Anxiety

The Penn State Worry Questionnaire (PSWQ) is widely used in research and clinical practice to measure the tendency to worry in general. it includes 16 items assessing the general tendency to worry in adults. Patients are asked to respond spontaneously to 16 proposals by selecting the mention that best suits them

the variation of power spectrum value or each frequency band (delta : [0.5 - 3] Hz, thêta : ]3 - 8] Hz, alpha : ]8 - 12] Hz, beta : ]12 - 25] Hz, gamma > 25 Hz) induced by exposure to an anxiety-inducing scenario will be compared between relevant epochs (anxiety-induced scenario and baseline) in patients suffering from GAD and controls, for each of the regions monitored.

Test designed to measure the intellectual quotien (IQ) in terms of "verbal" and "performance". It is composed of 10 main mandatory subtests and 5 optional complementary subtests. These subtests are divided into four indices (verbal understanding, perceptual reasoning, working memory and processing speed). Scores ranged from 50 (minimum) to 150 (maximum).

Normal values depend on its calibration according to the age of the subject and its level of education) is a test designed and validated to evaluate the learning and auditory and visual memory of a subject. They test different aspects of memory, including immediate recall, delayed recall, and recognition of visual and verbal stimuli.

QOLI-E 31 containt 7 subtests evaluating the different health concepts (emotional well-being, social functioning, energy/fatigue, cognitive functioning, crisis anxiety, drug effects and overall quality of life).

Self-questionnaire of depressive disorder testing validated for epilepsy. Scores ranged from 0 (minimum) to 24(maximum). It consists of six items assessing depressive symptoms. Each item is rated on a 4-point Likert scale (1: never 2: rarely; 3: sometimes; 4: always or often, over the last two weeks). The total score is obtained by adding the score obtained for each item. A total score strictly higher than 15 must be suspected depressive syndrome. This questionnaire is also validated and has excellent psychometric properties (sensitivity and specificity) in the clinical population with epilepsy.

Self-test for anxiety disorders, including Generalized Anxiety Disorder. It consists of seven items assessing psychological and somatic anxiety symptoms. Each item is rated on a 4-point Likert scale (0: never; 1: several days; 2: more than half the time; 3: almost every day, over the last two weeks). The total score is obtained by adding the score obtained for each item (score ranging from 0 to 21). A total score strictly higher than 7 must make suspect a generalized anxiety disorder. If the score is higher than 7, it is advisable to have the diagnosis of TAG confirmed by a clinical psychiatric evaluation. This questionnaire is also validated and has excellent psychometric properties (sensitivity and specificity) in the clinical population with epilepsy.

Scores ranged from 0 to 63. Self-assessment tool containing twenty-one elements that each describe one of the specific symptoms of depression. It can screen for recent depressive symptoms that have occurred in the past two weeks, and assess their severity. It can be used in subjects suffering from epilepsy. Each item is rated according to its intensity on a 4-point scale ranging from 0 (light intensity) to 3 (severe intensity). The maximum BDI score is 63 and the threshold for defining the presence of depression varies from 10 to 17, depending on the studies

Hetero-questionnaire of mood assessment. It is rated by a trained clinician in its passing and consists of 10 items that each have a general definition and six degrees of severity of a symptom, with degrees 0, 2, 4 and 6 being themselves defined. The overall score (0 - 60) results from the addition of item scores.

STAI is a two-part self-assessment questionnaire that independently assesses anxiety-trait and anxiety-state. They each include 20 items graduated in 4 degrees depending on their intensity or frequency. In the line-anxiety scale, the subject must indicate the point that best corresponds to the frequency of what he feels according to 4 degrees: 1 = almost never; 2 = sometimes; 3 = often; 4 = almost always. In the anxiety-state scale, the subject must indicate the point that best corresponds to the intensity of what he feels, also according to 4 degrees: 1 = no, 2 = rather no, 3 = rather yes, 4 = yes. The trait-anxiety scale is primarily used to assess the subject's usual anxiety temperament, while the state-anxiety scale is used to independently quantify current anxiety at the time of passing.

utoquestionnaire that allows a quantitative estimate of the intensity of the anxiety feeling. It consists of 21 items of symptoms and attitudes resulting from panic and generalized anxiety disorders, evaluated over the last 7 days, graduated from 0 to 3 according to a Lickert scale

Hetero-questionnaire intended to measure the severity of anxiety. It consists of 14 items corresponding to psychic and somatic anxiety symptoms noted on a 5-point Likert scale (0 - 4, in the increasing sense of severity). The overall score (0 - 56) results from the addition of the scores of items Hamilton et al. 1959. This is a classic trans-nosographic measure of the severity of anxiety. Its usefulness in this study consists of its evaluation by one. e clinician, while all other measures of anxiety are informed by patients
