ICU psychosis is a disorder in which patients in an intensive care unit (ICU) or a similar setting experience anxiety, hear voices, see things that are not there, and become paranoid, severely disoriented in time and place, very agitated, or even violent, etc. In short, patients become temporarily psychotic..
The difference between a continent and a island is that continents sit on their own continental lithosphere and islands do not. Greenland is the largest island and Austral â¦ ia is the smallest continent.
An island is a land mass surrounded by water on all sides. As for continents:  'Continents are understood to be large, continuous, discrete masses of land, ideally separated by expanses of water.'[1] However many of the seven most commonly recognized continents are identified by convention rather than adherence to the ideal criterion that each be a discrete landmass, separated by water from others.
