Abstract
The aim of this chapter is to provide an overview of ASC arising from varied origins. This chapter includes case studies of altered conscious states which aid in linking theory to clinical practice. In the first section we introduce the concept of consciousness and elaborate further on altered states of consciousness. In the second section physiologically induced ASC will be outlined and discussed with reference to situations that nurses may frequently encounter. The third section will focus on psychosis, hallucinations and delusions. These are considered exemplars of ASC, here we explore and evaluate cognitive psychology’s contribution to accounting for the complex phenomenology of the unusual experiences of psychosis. The final section focuses of ASC that result from intention, i.e. as a consequence of alcohol or drug use. Psychological theories, associated psychological issues, and supportive evidence based interventions will be discussed.
