In this chapter, we analyze fundamental concepts of psychiatry: attention disorders and disturbances of consciousness. A patient's ability to orient themselves in place, time, and their own identity is the baseline from which any psychiatric examination and assessment of disease severity begins.
The section consists of three key blocks: general disturbances of consciousness (quantitative changes ranging from obtundation to coma), qualitative clouded states of consciousness (delirium, oneiric syndrome, amnesia, twilight state), and attention disorders (exhaustibility, distractibility, inertia).
In classes and exams, you are most often asked to list Jaspers' criteria for impaired consciousness and to differentiate clouded states of consciousness from one another. Pay special attention to the clinical presentation of delirium and oneiric syndrome—these are absolute classics for both exam tasks and real-life on-call shifts in the emergency admission department.
