Alexithymia: Characteristics, Diagnostic Procedures, and Associated Disorders
In the realm of mental health, a relatively lesser-known yet significant phenomenon is gaining attention: alexithymia. This construct, first described by psychiatrist Peter Sifneos in the 1970s, relates to a difficulty in experiencing, identifying, and expressing emotions [1].
Although the exact cause of alexithymia remains elusive, some studies suggest it may stem from genetics, environmental factors, or brain injury [2]. What is clear, however, is its prevalence and impact across various mental health conditions.
Alexithymia is commonly associated with conditions such as depression, anxiety, psychosomatic disorders, sleep disturbances, aggression, and autism spectrum disorder (ASD) [1][2][3][4]. For instance, individuals with depression often struggle with emotional processing, which can exacerbate depressive symptoms and negatively affect treatment outcomes [1][2][3].
Anxiety and alexithymia also share a strong bond, with the difficulty in identifying and describing emotions heightening anxiety symptoms [1]. Similarly, in populations with trauma or childhood maltreatment, alexithymia is associated with increased aggression due to impaired emotion regulation [3].
The link between alexithymia and ASD is particularly noteworthy, with approximately half of autistic people likely experiencing alexithymia, especially those with complex ASD [4]. The social and emotional difficulties experienced by those with ASD may not be a feature of autism itself, but rather of co-occurring alexithymia.
Research also suggests an association between alexithymia and eating disorders, where people often report problems identifying or describing their emotions [5]. Moreover, higher levels of alexithymia are linked with less favorable treatment outcomes for eating disorders [6].
People with PTSD may also exhibit alexithymic traits at a higher rate than those without PTSD, particularly in males and veterans with PTSD [7]. Symptoms of alexithymia include difficulties identifying feelings and emotions, problems distinguishing between emotions and bodily sensations, limited ability to communicate feelings to others, and more [8].
Despite its prevalence and impact, alexithymia is not a mental health disorder. Instead, it is a phenomenon that mental health professionals do not formally diagnose [9]. However, there are questionnaires and scales, such as the Twenty-Item Toronto Alexithymia Scale (TAS-20) and the Bermond-Vorst Alexithymia Questionnaire (BVAQ), that professionals can use to check for signs of alexithymia [10].
While there are no official treatment guidelines for managing alexithymia, people can seek treatment for conditions that co-occur with alexithymia, such as depression or ASD [9]. A 2022 review of research notes that around 10% of the population experience alexithymia, and it may be more common in males than females [11].
In conclusion, alexithymia is a complex and multifaceted phenomenon that commonly co-occurs with various mental health conditions. Its impact on emotional processing and regulation underscores the importance of continued research and understanding in this area.

- Alexithymia, a construct related to struggling with emotional experiences, identification, and expression, may be linked to multiple mental health conditions such as depression, anxiety, psychosomatic disorders, and autism spectrum disorder (ASD).
- Individuals with depression often battle emotional processing issues, which can worsen depressive symptoms and affect treatment outcomes.
- Anxiety and alexithymia share a strong bond, with the difficulty in identifying and describing emotions heightening anxiety symptoms.
- In populations with trauma or childhood maltreatment, alexithymia is associated with increased aggression due to impaired emotion regulation.
- The link between alexithymia and ASD is significant, with approximately half of autistic people susceptible to alexithymia.
- Research suggests an association between alexithymia and eating disorders, where people often report difficulties identifying or describing their emotions, leading to less favorable treatment outcomes.
- People with PTSD may exhibit alexithymic traits at higher rates, particularly in males and veterans with PTSD, resulting in difficulties identifying feelings and emotions, problems distinguishing between emotions and bodily sensations, limited ability to communicate feelings to others, and more.
- Although alexithymia is not a mental health disorder, it is crucial to increase research and understanding of this phenomenon, given its prevalence and impact on various health-and-wellness and mental-health aspects like depression, ASD, and psoriatic arthritis as per predictive science.
