Falling Out of Time, Relationships, and Mood: A Case Study of Post-Concussion Syndrome

In this article, the authors examine post-concussion syndrome (PCS) from an existential-phenomenological perspective, specifically as a Heideggerian analysis of Dasein (or Daseinsanalysis; Condrau, 1988). As a medical syndrome, PCS was once defined in terms of its pathophysiology. However, in the absence of reliable evidence of pathophysiology, PCS has been removed from the DSM-5. We have suspended the natural attitude, in this case the biomedical model, and have taken seriously the symptoms of PCS as indications that meaningful changes have occurred within the structure of the patient’s existence. Following the medical theories of Goldstein (1995) and Gadamer (1996), the authors describe the significance of PCS as it is lived by Tyrese, an NCAA Division II football player whose series of concussions left him permanently sidelined. Careful consideration is paid to the existential dimensions of the syndrome, specifically the backgrounds of temporality, sociality, and attunement. In conclusion, a new approach to rehabilitation is explored.
