What is pseudo psychosis?
It is a condition resembling psychosis.
NOTE that it only resembles Psychosis (which is a severe mental disorder in which thought and emotions are so impaired that contact is lost with external reality).
BUT It may be a factitious (artificially created or developed). It can be caused by factors like a frontal lobe injury or damage, trauma, strokes, etc.
OR malingering disorder (exaggerate or feign illness in order to escape duty or work). (Seriously in my life, I never met real people do this).
Hope this helps ^_^.
