Psychiatry 1999 Jun;45(11):1393-402 PMID: 10356620 Abstract BACKGROUND: Structural MRI data indicate schizophrenics have reduced left-sided temporal lobe gray matter volumes, especially in… read more →
Farmer CM, O’Donnell BF, Niznikiewicz MA, Voglmaier MM, McCarley RW, Shenton ME Am J Psychiatry 2000 May;157(5):781-8 PMID: 10784472 Abstract OBJECTIVE: Patients affected by schizophrenia show deficits in both visual perception and working memory. The authors tested early-stage vision and working memory in subjects with schizotypal personality disorder, which has… read more →
Dickey CC, Shenton ME, Hirayasu Y, Fischer I, Voglmaier MM, Niznikiewicz MA, Seidman LJ, Fraone S, McCarley RW Am J Psychiatry 2000 Jan;157(1):48-54 PMID: 10618012 Abstract OBJECTIVE: The purpose of this study was to determine whether schizotypal personality disorder, which has the same genetic diathesis as schizophrenia, manifests abnormalities in… read more →
Niznikiewicz MA, Voglmaier MM, Shenton ME, Dickey CC, Seidman LJ, Teh E, Van Rhoads R, McCarley RW Biol. Psychiatry 2000 Oct;48(7):702-5 PMID: 11032982 Abstract BACKGROUND: Reduced, left-lateralized P3 amplitude has been reported in several studies focusing on electrophysiologic function in schizophrenia. Also, several lines of evidence suggest a similarity between… read more →
Voglmaier MM, Seidman LJ, Niznikiewicz MA, Dickey CC, Shenton ME, McCarley RW Am J Psychiatry 2000 May;157(5):787-93 PMID: 10784473 Abstract OBJECTIVE: The authors contrasted verbal and nonverbal measures of attention and memory in patients with DSM-IV-defined schizotypal personality disorder in order to expand on their previous findings of verbal learning… read more →
Levitt JJ, McCarley RW, Dickey CC, Voglmaier MM, Niznikiewicz MA, Seidman LJ, Hirayasu Y, Ciszewski AA, Kikinis R, Jolesz FA, Shenton ME Am J Psychiatry 2002 Jul;159(7):1190-7 PMID: 12091198 Abstract OBJECTIVE: “Cognitive” circuits anatomically link the frontal lobe to subcortical structures; therefore, pathology in any of the core components of… read more →
Dickey CC, McCarley RW, Shenton ME Harv Rev Psychiatry 2002 Jan-Feb;10(1):1-15 PMID: 11751641 Abstract Studies of schizotypal personality disorder (SPD) are important because the condition is genetically related to schizophrenia and because data accumulating to confirm its biological underpinnings are challenging some traditional views about the nature of per-sonality disorders.… read more →
Dickey CC, McCarley RW, Voglmaier MM, Frumin M, Niznikiewicz MA, Hirayasu Y, Fraone S, Seidman LJ, Shenton ME Am J Psychiatry 2002 Sep;159(9):1521-7 PMID: 12202272 Abstract OBJECTIVE: Individuals with schizophrenia spectrum disorders evince similar genetic, neurotransmitter, neuropsychological, electrophysiological, and structural abnormalities. Magnetic resonance imaging (MRI) studies have shown smaller gray… read more →
Dickey CC, McCarley RW, Voglmaier MM, Niznikiewicz MA, Seidman LJ, Frumin M, Toner S, Demeo S, Shenton ME Schizophr. Res. 2003 Nov;64(1):35-9 PMID: 14511799 Abstract The fusiform gyrus is important for face and object recognition, is abnormal in schizophrenia, but has not been studied in schizotypal personality disorder (SPD). Thin-slice… read more →
