Effect of social exclusion on dopamine function in the human brain. A SPECT study in young adults with serious hearing impairment.

According to the social defeat hypothesis the long-term experience of social exclusion or social defeat leads to enhanced baseline activity and/or sensitization of the mesolimbic dopamine (DA) system and puts the individual at increased risk for psychotic disorder and/or schizophrenia. This pilot study tests the hypothesis by comparing DAergic function in two groups who are expected to differ greatly:
(1) young adults with a serious hearing impairment (HI) who cannot participate in group conversations and are therefore socially excluded;
(2) normal hearing peers.
