Psychosis is a loss of contact with reality. Psychosis often involves delusions and seeing or hearing things that others can not see or hear (hallucinations.) People with psychosis often feel fearfulness or suspiciousness (paranoid). Psychosis may develop suddenly or gradually. Psychosis may occur as part of other mental health disorders. Some people with depression develop psychosis and some older people with dementia have psychosis. Drugs called anti psychotic can be effective in reducing the symptoms of psychosis.
People who drink too much coffee are in danger of having illusions and seeing ghosts during the day according to a new research. Our body releases a hormone called cortisol whose production is triggered by caffeine. This hormone actually leads to illusions and hallucinations. This research is directly linked to the intake of caffeine which is major content of coffeine. However, caffeine is also present in tea and chocolate. So research has also linked caffeine to miscarriages of birth problems about women.
