Brief psychotic disorder ⁠— according to the classifications of mental disorders DSM-IV-TR and DSM-5 ⁠— is a psychotic condition involving the sudden onset of at least one psychotic symptom (such as disorganized thought/speech, delusions, hallucinations, or grossly disorganized or catatonic behavior) lasting 1 day to 1 month, often accompanied by emotional turmoil. Remission of all symptoms is complete with patients returning to the previous level of functioning. It may follow a period of extreme stress including the loss of a loved one. Most patients with this condition under DSM-5 would be classified as having acute and transient psychotic disorders under ICD-10. Prior to DSM-IV, this condition was called "brief reactive psychosis." This condition may or may not be recurrent, and it should not be caused by another condition. The term bouffée délirante describes an acute non-affective and non-schizophrenic psychotic disorder, which is largely similar to DSM-III-R and DSM-IV brief psychotic and schizophreniform disorders. Presentation
BPD is characterized by a sudden onset of psychotic symptoms, which may include delusions, hallucinations, disorganized speech or behavior, or catatonic behavior.Symptoms generally last at least a day, but not more than a month, and there is an eventual return to full baseline functioning. BPD may occur in response to a significant stressor in ones life, or in other situations where a stressor is not apparent, including in the weeks following birth.In diagnosis, a careful distinction is considered for culturally appropriate behaviors, such as religious beliefs and activities.
Stereotypic movement might also result in self harm. Behavioral abnormalities can also hinder social relations effectively. Affected individuals tend to become apathetic and withdrawn. Antisocial behavior might manifest as lying or stealing. Disrupted social functions related to a lack of socialization and integration can lead to further isolation. Hygiene and appearance may also be negatively impacted. Consequences and complication
The consequences of hospitalism can be detrimental for the people affected and reveal themselves in different ways. It is noteworthy that the symptoms can vary across different individuals, and several factors, such as age, play a significant role.Patients are also at higher risk for various mental disorders and anti-social behaviors:
anxiety disorders
depression
borderline-personality disorder
suicidal tendencies
apathy  
low self-esteem  
autoaggressive behaviour
attachment anxiety  
adjustment and communication disorders
tendencies towards aggressive behaviour
lack of personal hygieneIndividuals suffering from hospitalism are also at risk for sensory perception problems:
altered or delayed pain perception  
fear of touch  
hypersensitivity   Other common consequences relate to cognitive disorders, such as:
learning disabilities
rarely memory lapses or even loss of long- or short-term memory  
motor disorders such as monotonous and sterotyped movements (for example, banging the head against the wall) or a severely reduced ability to reactLong-term consequences, which is causally related to traumatic experiences, can be expressed in different ways. People showing signs of hospitalism might express an extreme aversion towards showing or accepting emotional or physical affection, effectively shutting themselves off from others. A different response could be promiscuity, whereas people strive for love and affection.
