Abreaction is episode of emotional release associated 
with bringing previously repressed emotional experiences 
(e.g., physical, sexual, and/or emotional abuse or trauma) 
into conscious recollection. The term is often used by 
those who practice psychoanalysis, a branch of 
psychotherapy begun by the famous neurologist, Sigmund 
Freud. Abreact means a) to show strong emotion while 
reliving a prior experience that was traumatic and b) 
release of emotions that had been repressed. 
 
Abreaction is considered a form of catharsis (emotional release). The purpose of 
abreaction is to purge the body of emotional excess. While Freud was a proponent of 
abreaction, another famous psychoanalysis (Carl Jung) believed that the skill, 
enthusiasm, and confidence of the therapist (known as an analyst in psychoanalytic 
circles) were more important than abreaction.
Abreaction is still used in modern psychotherapy and psychology as a way to treat  
posttraumatic stress disorder (PTSD), in which a person develops certain signs and  
symptoms after being exposed to an extreme traumatic stressor, causing clinically  
significant impairment in social, occupational, or other important areas of functioning. 
 
The traumatic experiences are sometimes brought 
to the surface in abreaction therapy via hypnosis. 
Hypnosis is a technique in which a person is 
placed in a mental state that resembles sleep and 
is given suggestions that the person will accept. 
When the emotions are brought to the surface, it 
occurs in a controlled environment. The technique 
is conceived as akin to popping pimple, in which 
releasing the pus (analogy for negative emotions) 
allows for healing to take place. However, the 
experience can be very distressing for the patient 
and does not always work.
