Alexithymia is widely viewed as an impairment in emotion processing that includes difficulty identifying and describing emotions. While there is a significant understanding of primary alexithymia, which is thought to be the result of developmental genetic and familial factors, secondary and organic alexithymia are beginning to be focus of research. Method and results: The present review of the literature suggests the importance of differentiating between primary and secondary alexithymia, and the organic subtype of secondary alexithymia. Secondary alexithymia is thought to be a consequence of psychological stress, chronic disease, or organic processes (e.g. brain trauma or stroke) that occur after childhood (whereas primary alexithymia is a developmental phenomenon). Organic insults to the brain may bring about the organic form of alexithymia by altering cerebral structures involved in emotional processing (e.g. anterior cingulate cortex, frontostriatal networks, callosum corpus, right hemisphere cortex and amygdala). The usefulness of differentiating among alexithymia categories and their relationships with brain structures known to subserve emotional processing is discussed. Conclusion: We propose that differentiating between primary, secondary and organic alexithymia may potentially serve to develop better treatments for alexithymia.

Eighty-five participants (MCI = 30, AD = 21, HC = 34) underwent a comprehensive neuropsychological examination and completed the 20-item Toronto Alexithymia Scale (TAS-20). Relative to HC, MCI and AD reported greater alexithymia total scores and higher scores on the TAS factor difficulty in identifying feelings (DIF). The remaining two factors, difficulty in describing feelings (DDF) and externally oriented thinking showed no significant group differences. In MCI, TAS-20 and DIF were negatively correlated with working and long-term verbal memory. In AD, TAS-20 was negatively correlated with general cognition, attention, memory, and visual spatial constructive and executive abilities. Also in AD, DIF was negatively correl...

Older persons show changes in emotion processing and have higher alexithymia scores. Because the anterior cingulate cortex (ACC) is one of the regions showing earlier decline in late-life, and alexithymia seems to be related to a dysfunction in right hemisphere regions including the ACC subserving affective processes, the present study sought to test the hypothesis that reduced ACC volume accounts for the association between older age and alexithymia.

The aim of this study was to examine the incidence of neglect among patient groups with right or left insular infarction. Methods —We examined neglect in 9 right-handed subjects with insular stroke as evidenced by CT and/or MRI scans (4 with right insular and 5 with left insular cerebrovascular accident) between 4 and 8 weeks after acute stroke with tests of visual, tactile, and auditory perception. Results —Compared with patients with left insular lesions, patients with right insular lesions showed significant neglect in the tactile, auditory, and visual modalities. Conclusions —The right insular cortex seems to have a role in awareness of external stimuli, and infarction in this area may lead to neglect in multisensory modalities.
