Depression as a Disorder of Consciousness

First-person reports of major depressive disorder reveal that when an individual be- comes depressed a profound change or ‘shift’ to one’s conscious experience occurs. The depressed person reports that something fundamental to their experience has been disturbed or shifted, a change associated with the common but elusive claim that when depressed one finds oneself in a ‘different world’ detached from reality and other peo- ple. Existing attempts to utilize these phenomenological observations in a psychiatric context are challenged by the fact that this experiential ‘shift’ characteristic of depres- sion appears mysterious and resists analysis in scientific terms. This article offers a way out of this predicament. The hypothesis proposed is that when an individual be- comes depressed, the individual departs from a state of ordinary wakeful consciousness and enters a distinctive global state of consciousness akin to dreaming and the psyche- delic state. After unpacking and motivating this hypothesis in the context of research in consciousness science, I outline two of its important implications for the neurobiol- ogy of depression and psychedelic psychiatry. The upshot is a promising and concep- tually well-motivated hypothesis about depression that is apt for empirical uptake and development.
