Disease in which people avoid social activities, as well as third-party interactions constantly. Schizoid personality disorder's prevalence is low, at an estimated 3% amongst the general population.
Even though its exact cause is still unknown, it is believed to be a combination of genetic and environmental factors.
Schizoid personality disorder symptoms include a lack of interest in social relationships, emotional restriction, apathy, emotional coldness and indifference to being judged or the others' approval. Symptoms tend to appear during the teenage years or at the start of young adulthood and can be associated to other mental disorders such as schizophrenia.
Schizoid personality disorder's diagnosis is reached through clinical observation and psychological testing.
Treatment tends to include cognitive-behavioural therapy, group therapy and support therapy.
