A critical and descriptive approach to interictal behavior with the Neurobehavior Inventory (NBI)

Abstract

Depression influences NBI scoring, mainly emotionality and hyposexuality traits. Neurobehavior Inventory subscales can be better interpreted with an appropriate evaluation of comorbid mood and anxiety disorders. Compromise in left temporal mesial structures is associated with increased tendency toward sad affect, whereas right temporal pathology is associated with increased beliefs in personal destiny.

Revisiting personality in epilepsy: Differentiation of personality in two epilepsies starting in adolescence

“…A total score of 20 or more affirmative statements and three or more positive answers in each subscale determine the existence of the characteristic [11]. Neurobehavior Inventory traits will be classified according to de Oliveira et al [7], which are included in Table 1 showing NEO-PI-R and NBI contents.…”

“…The sense of personal destiny, seriousness, religious conviction, writing tendency, and cosmic interest were significantly elevated in MTLE/HS while in JME, higher scores were found in anger and temper, dependency, emotion, and somatic complaints. De Oliveira et al [7] identified three main components in NBI corresponding to features related to Gastaut-Geschwind syndrome: emotions (Factor 1), hyposexuality (Factor 2), and unusual ideas (Factor 3). In our JME group, higher scores were observed in traits of Factor 1 while in MTLE/HS, traits of Factor 3 were more elevated.…”

“…The controversial relationship between epilepsy and personality characteristics has been recognized for centuries, with important studies emphasizing this association [1][2][3][4]. In contrast, the findings and evidence of some studies for the existence of an epileptic personality are inconsistent [5][6][7][8].…”

“…After an initial precipitating injury, this condition initiates mainly during adolescence, has a consistent etiology, with unquestionable Magnetic Ressonance Imaging (MRI) examination of the brain and histopathological findings showing the involvement of limbic system structures, particularly the hippocampus and the amygdala, related to emotion and behavioral responses [9,10]. Traits of personality in TLE according to Bear and Fedio [3] comprises 18 characteristics, later increased to 20 [11], even though since then, all traits have not been found together in the literature report [7,8,[12][13][14]. Some of the most cited are represented by religiosity and philosophical interest, sense of personal destiny, hypergraphia, hypermoralism, ethical arouse, tendency to be orderly, dependence, circumstantiality, irritability, increased emotionality, sadness, obsessionalism, altered sexuality, and other features related to interictal personality disorder of epilepsy, referred to as "Gastaut-Geschwind syndrome" [2,4].…”

“…The NEO Revised Personality Inventory (NEO-PI-R) is one of the inventories based on the Big Five Model and validated to Brazil [29]. Based on "Gastaut-Geschwind" records, another important instrument used to assess TLE interictal features is the Neurobehavior Inventory (NBI) developed by Blumer [11], according to Bear and Fedio's previous report [3]; this instrument has a Brazilian-Portuguese adaptation with evaluation of its psychometric properties [7].…”
