ABSTRACT
Over the past 20 years, the advent of advanced techniques has significantly enhanced our knowledge on the brain. Yet, our understanding of the physiological and pathological functioning of the mind is still far from being exhaustive. Both the localizationist and the reductionist neuroscientific approaches to psychiatric disorders have proven to be largely unsatisfactory and are outdated. Accruing evidence suggests that psychoanalysis can engage the neurosciences in a productive and mutually enriching dialogue that may further our understanding of psychiatric disorders. In particular, advances in brain connectivity research have provided evidence supporting the convergence of neuroscientific findings and psychoanalysis and helped characterize the circuitry and mechanisms that underlie higher brain functions. In the present paper we discuss how knowledge on brain connectivity can impact neuropsychoanalysis, with a particular focus on schizophrenia. Brain connectivity studies in schizophrenic patients indicate complex alterations in brain functioning and circuitry, with particular emphasis on the role of cortical midline structures (CMS) and the default mode network (DMN). These networks seem to represent neural correlates of psychodynamic concepts central to the understanding of schizophrenia and of core psychopathological alterations of this disorder (i.e., ego disturbances and impaired primary process thinking).
ABSTRACT
BACKGROUND: The association between alexithymia and post-traumatic stress disorder (PTSD) symptoms has been demonstrated in several studies, but never in victims of a collective trauma such as a natural disaster, which has an impact on an entire community. AIMS: The aim was to assess the relationship between alexithymia and post-traumatic symptoms in a group of people who lived in L'Aquila exposed to the earthquake that hit the town in 2009. METHODS: Eighty-seven participants were included and assessed for alexithymia, PTSD symptoms, depression, anxiety, and psychiatric symptoms. Linear regression models were used to test the hypothesis. RESULTS: The main finding was an association between "Difficulty-Describing-Feelings" and the intensity of post-traumatic symptoms in the worst month after trauma. Depression, anxiety and psychiatric comorbidity also showed a significant association with PTSD symptoms. CONCLUSIONS: In the present study of a collectively shared trauma, the alexithymic factor "difficulty-describing-feelings" was significantly associated with the intensity of post-traumatic symptoms.
