mTBI can lead to a wide array of cognitive, emotional, and somatic symptoms ( Bergersen, Halvorsen, Tryti, Taylor, & Olsen, 2017). In addition, patient-level characteristics such as age, sex, premorbid headaches, and psychiatric conditions likely influence resilience and vulnerability to mTBI sequelae, as well as the persistence of postconcussive symptoms. mTBI is a remarkably heterogeneous condition with varying degrees of clinical manifestations and severity. Of the annual cases of traumatic brain injury, the World Health Organization estimates that 70%–90% of those are mild TBI ( Cassidy et al., 2004). In patients with typical mTBI, standard acute structural imaging studies such as head computed tomography scans do not show hemorrhage or other overt structural abnormalities, although specialized imaging techniques may show evidence of diffuse axonal injury ( Amyot et al., 2015). While different definitions exist, mild TBI (mTBI) is often characterized by GCS of 13–15, brief AOC or LOC, and PTA for less than 1 h. Injury severity is traditionally based on Glasgow Coma Scale (GCS), duration of loss of consciousness (LOC) or alteration of consciousness (AOC), posttraumatic amnesia (PTA), and brain imaging results. Based on factors assessed at the time of injury, as well as findings on neuroimaging, TBIs are classified as mild (mTBI or concussion), moderate, or severe ( Bryan, 2013). TBI is an alteration in brain function or other brain pathology due to the impact of contact forces, including rapid acceleration, deceleration, or collision, manifesting as an altered state of consciousness, neurological deficits, and/or amnesia ( Katz, Cohen, & Alexander, 2015).
ALTERED CONSCIOUSNESS HOW TO
Henry Orff, in Adapting Cognitive Behavioral Therapy for Insomnia, 2022 How to recognize and diagnose TBI While more, and especially more systematic research is needed, we identify a general trend, suggesting that factors that induce ASC are likely to alter the metacontrol state by biasing it toward either persistence, which is beneficial for convergent thinking and other persistence-heavy operations, or flexibility, which is beneficial for divergent thinking and other flexibility-heavy operations.Įrin A. We discuss behavioral and neuronal findings from three areas that reflect strong connections between ASC and the underlying effects on metacontrol on the one hand and components of creativity on the other hand: drug-induced ASC, meditation-induced ASC, and hallucinations. We provide a metacontrol framework that allows characterizing factors that induce ASC in terms of their general impact on the information processing style of problem solvers. Increasing evidence suggests that altered states of consciousness (ASC) are associated with both positive and negative effects on components of creative performance, and convergent and divergent thinking in particular.
