We are not all the same. In fact we are often blind to the people we live with, to their personality and character traits, because we live within our own personality biases. Without psychotherapeutic work, we are often not aware of the fact that we see and feel the world differently from the people around us. That we also have a tendency to assume that the other person understands us and vice versa.
Alexithymia is not uncommon. It is assumed that about 10% of the population is alexithymic. With awareness through psychotherapy, one may get to realize that one is or had been living with persons who are unable to identify and describe emotions in the self. This condition is seen as dysfunctional because it leaves the person un-empathic, and the people around the sufferers often get hurt.
Alexithyma proves to be prominent in a number of clinical disorders (e.g., somatoform disorders, panic disorders, depression with dominance of vital and somatic symptoms, posttraumatic stress disorder [PTSD], and eating disorders). Extent of Alexithymia is also significant to outcome in the treatment of these disorders.
Psychological questionnaires used to measure Alexithymia include: Observer Alexithymia Scale (Haviland et.al, 2001) and the the Bermond-Vorst Alexithymia Questionnaire (Vorst et.al, 2001).
