“…To address the methodological weaknesses of the study by Cole and Bakan [51], Parker et al [52]replicated it using the TAS in addition to the SSPS, otherwise using the exact same methodology. Subjects were 60 right-handed university students.…”

“…These findings support the RH underactivation hypothesis of alexithymia and suggest that the finding by Cole and Bakan [51]may be due to the low reliability of the SSPS. Nonetheless, as Parker et al [52]point out, the validity of CLEMs as an index of hemisphericity is questionable, as results tend to vary with subtle differences in methodology. In addition to the variable task-specific effects, CLEM studies have also been criticized for failing to report consistent individual differences [54].…”

Background: One neural model of alexithymia relates the condition to poor interhemispheric transfer, while another model associates it with a disturbance in right hemisphere activity. Methods: The available empirical evidence directly relating alexithymia to a deficit in interhemispheric transfer and/or in right hemisphere activity is critically reviewed. Results: The interhemispheric transfer studies have related alexithymia to a deficit in transfer, but the nature and directionality of the transfer deficit have yet to be determined. Many of the hemispheric specialization studies do not relate alexithymia to a right hemisphere dysfunction. Shortcomings of these studies are reviewed. Conclusions: The hypothesis that alexithymia is related to a deficit in the right-to-left transfer of emotional information and to a right hemisphere impairment in emotion processing remains to be tested directly and definitively. Suggestions for future research are made.

“…Studies investigating conjugate lateral eye movements found conflicting results on the right hemisphere activity in alexithymia [19, 20]. In a PET study, Lane et al [21]found reduced activation of the right anterior cingulate cortex in subjects with a low level of emotional awareness during an emotional stimulation paradigm.…”

Objective: This study investigates the hypothesis that alexithymia is associated with an interhemispheric transfer deficit via the corpus callosum (CC). Method: The transcallosal inhibition paradigm was used to assess interhemispheric transfer. Transcranial magnetic stimulation (TMS) and peripheral electromyographic recordings were performed in 10 right-handed male and 10 female students with Toronto Alexithymia Scale (TAS-20) scores of ≧61 and controls (TAS-20 scores of <61). The transcallosal conduction time (TCT) reflects the TMS-induced inhibitory cortical activity that is mediated via the CC. Results: There was a significant interaction between gender and alexithymia (Wilks λ = 0.89; F = 3.4; d.f. = 2, 57; p = 0.04) indicating that alexithymic males had shorter bidirectional TCTs than controls and a significantly shorter left to right TCT than controls (p = 0.002). However, the left to right TCT was not significantly different from the right to left TCT in alexithymic males (p = 0.39). Alexithymic females were not different from controls. Conclusion: Our results clearly stand in contrast to the hypothesis of a transfer deficit due to a dysfunction of the CC in alexithymia. Facilitated, bidirectional transcallosal inhibition of the contralateral motor activity is associated with alexithymia in males. Facilitated cortical inhibition may be a neurobiological correlate of alexithymia.

ОБЗОРЫИзвестно, что ряд психосоматических патологиче-ских состояний оказывает влияние на течение сопутству-ющих заболеваний, в связи с чем зачастую приходится менять терапевтическую тактику. Одним из факторов, способных вызывать психосоматические проблемы, явля-ется алекситимия (АТ). Под АТ понимается неспособ-ность индивидуума адекватно понимать и выражать соб-ственные чувства и телесные ощущения, а также воспри-нимать чужие эмоции. Считается, что люди с разной сте-пенью выраженности АТ имеют достаточно скудную фан-тазию, у них, как правило, слабо или весьма умеренно развито воображение [1,2].Первым проблему АТ обозначил П. Сифнеос [1]. Дальнейшие исследования в данной области проводи лись и проводятся весьма интенсивно, и на сегодняшний день АТ является одной из значимых проблем неврологии и нейропсихологии. В течение последних двух десятилетий проблемы АТ широко и подробно освещаются в медицин-ской литературе. Основные результаты этих исследований обсуждаются в представленном обзоре.В настоящее время проводятся исследования, в кото-рых выясняют, является ли АТ специфическим свойством личности или же она может лишь предрасполагать к пси-хосоматическим заболеваниям, являясь их предиктором. Некоторые исследователи полагают, что АТ сама по себе не является заболеванием и представляет собой ряд харак- В обзоре рассматриваются современные представления о формировании алекситимии. Анализируется возможность ее возникновения при различных соматических и психосоматических заболеваниях, а также роль в развитии ряда психоневрологических заболеваний. Приведены данные о связи алекситимии и нарушений поведения, расстройств межличностных отношений. Рассматриваются способы диагностики алекситимии в условиях клинической практики при различных поражениях центральной нервной системы.Ключевые слова : алекситимия, когнитивные функции, нейролингвистический анализ, психосоматические заболевания, нейрофизиологический подход, боль. In this review, we considered current conceptions on the development of alexithymia. We analyzed the possibility of its development in different somatic and psychosomatic diseases as well as a role in the development of some psychoneurological diseases. The data on the relationship between alexithymia and behavioral disorders, disorders interpersonal relations are presented. Methods of diagnosis of alexithymia in clinical practice in patients with different lesions of the central nervous system are considered.
