Analytic information processing style in epilepsy patients.

Relevant to the study of epileptogenesis is learning processing, given the pivotal role that neuroplasticity assumes in both mechanisms. Recently, evoked potential analyses showed a link between analytic cognitive style and altered neural excitability in both migraine and healthy subjects, regardless of cognitive impairment or psychological disorders. In this study we evaluated analytic/global and visual/auditory perceptual dimensions of cognitive style in patients with epilepsy. Twenty-five cryptogenic temporal lobe epilepsy (TLE) patients matched with 25 idiopathic generalized epilepsy (IGE) sufferers and 25 healthy volunteers were recruited and participated in three cognitive style tests: "Sternberg-Wagner Self-Assessment Inventory", the C. Cornoldi test series called AMOS, and the Mariani Learning style Questionnaire. Our results demonstrate a significant association between analytic cognitive style and both IGE and TLE and respectively a predominant auditory and visual analytic style (ANOVA: p values <0,0001). These findings should encourage further research to investigate information processing style and its neurophysiological correlates in epilepsy.

Familial mesial temporal lobe epilepsies: clinical and genetic features.

Familial mesial temporal lobe epilepsy (FMTLE) was first described as a benign syndrome with prominent psychic and autonomic seizures and no association with hippocampal sclerosis (HS) or febrile seizures (FS). Better definition of the syndrome allowed identification of more heterogeneous phenotypes with mild to severe epileptic disorders, and a variable association with HS and FS. The genetics of these conditions is largely unknown and the hope for the future is that the identification of FMTLE genes will lead to more appropriate approaches for the diagnosis and treatment of TLE.

Depression, hopelessness and suicide risk among patients suffering from epilepsy.

Suicide risk, as well as psychiatric disorder, has been repeatedly reported in the international literature as an important issue in the care of individuals suffering from epilepsy. In this pilot study a sample comprising 103 patients with a diagnosis of temporal lobe epilepsy, were collected from three clinics. The patients were administered the Beck hopelessness scale (BHS), the Beck depression inventory (BDI) and the Zung self-rating anxiety scale (SAS). Hopelessness has been identified as a construct linked to the prediction and the prevention of suicide. Twenty-six percent of the epileptic patients had scores>or=9 on the BHS, suggesting that they should be evaluated for suicidal inclinations. These patients were significantly older by about 9 years and had higher levels of depression and anxiety, but they did not differ in sex, age of onset of epilepsy or in their responsiveness to medication. In the logistic regression analysis, a hopelessness score>or=9 was predicted by BDI depression scores and SAS anxiety scores taking into account sex, age and response to epileptic medications. Despite a number of limitations, this pilot study adds support for the need for screening for suicide risk in patients with epilepsy. Both clinical and psychometric data should be part of the evaluation of the epileptic patient for psychiatric and suicidality assessment.

Validation Study of Italian Version of Inventory for Déjà Vu Experiences Assessment (I-IDEA): A Screening Tool to Detect Déjà Vu Phenomenon in Italian Healthy Individuals.

The Inventory Déjà Vu Experiences Assessment (IDEA) is the only screening instrument proposed to evaluate the Déjà vu (DV) experience. Here, we intended to validate the Italian version of IDEA (I-IDEA) and at the same time to investigate the incidence and subjective qualities of the DV phenomenon in healthy Italian adult individuals on basis of an Italian multicentre observational study. In this study, we report normative data on the I-IDEA, collected on a sample of 542 Italian healthy subjects aging between 18-70 years (average age: 40) with a formal educational from 1-19 years. From September 2013 to March 2016, we recruited 542 healthy volunteers from 10 outpatient neurological clinics in Italy. All participants (i.e., family members of neurological patients enrolled, medical students, physicians) had no neurological or psychiatric illness and gave their informed consent to participate in the study. All subjects enrolled self-administered the questionnaire and they were able to complete I-IDEA test without any support. In total, 396 (73%) of the 542 healthy controls experienced the DV phenomenon. The frequency of DV was inversely related to age as well as to derealisation, jamais vu, precognitive dreams, depersonalization, paranormal activity, remembering dreams, travel frequency, and daydreams (all p < 0.012). The Italian version of IDEA maintains good properties, thus confirming that this instrument is reliable for detecting and characterising the DV phenomenon.
