Schizoid personality disorder (SPD) is a personality disorder characterized by a lack of interest in social relationships, a tendency towards a solitary lifestyle, secretiveness, emotional coldness and apathy. Affected individuals may simultaneously demonstrate a rich, elaborate and exclusively internal fantasy world, although this is often more suggestive of schizotypal personality disorder.
SPD is not the same as schizophrenia, although they share such similar characteristics as detachment or blunted affect. There is, however, increased prevalence of the disorder in families with schizophrenia.

Famous quotes containing the words personality and/or disorder:
“Talent alone can not make a writer. There must be a man behind the book; a personality which by birth and quality is pledged to the doctrines there set forth, and which exists to see and state things so, and not otherwise; holding things because they are things.”
—Ralph Waldo Emerson (1803–1882)
“Both of us felt more anxiety about the South—about the colored people especially—than about anything else sinister in the result. My hope of a sound currency will somehow be realized; civil service reform will be delayed; but the great injury is in the South. There the Amendments will be nullified, disorder will continue, prosperity to both whites and colored people will be pushed off for years.”
—Rutherford Birchard Hayes (1822–1893)
