Gerrit I. Schalkwyk, Carla E. Marin, Mayra Ortiz, Max Rolison, more

Journal of Autism and Developmental Disorders > 2017 > 47 > 9 > 2805-2813

Social media holds promise as a technology to facilitate social engagement, but may displace offline social activities. Adolescents with ASD are well suited to capitalize on the unique features of social media, which requires less decoding of complex social information. In this cross-sectional study, we assessed social media use, anxiety and friendship quality in 44 adolescents with ASD, and 56 clinical...

Gerrit I. Schalkwyk, Fred R. Volkmar, Philip R. Corlett

Journal of Autism and Developmental Disorders > 2017 > 47 > 5 > 1323-1340

The co-occurrence of psychotic and autism spectrum disorder (ASD) symptoms represents an important clinical challenge. Here we consider this problem in the context of a computational psychiatry approach that has been applied to both conditions—predictive coding. Some symptoms of schizophrenia have been explained in terms of a failure of top–down predictions or an enhanced weighting of bottom–up prediction...

Effective Research Mentorship for Residents: Meeting the Needs of Early Career Physicians

Gerrit I. Schalkwyk, Rachel B. Katz, Joseph Resignato, Susan C. Schalkwyk, more

Academic Psychiatry > 2017 > 41 > 3 > 326-332

Objective Challenges in pursuing research during residency may contribute to the shortage of clinician-scientists. Although the importance of mentorship in facilitating academic research careers has been described, little is understood about early career research mentorship for residents. The aim of this study was to better understand the mentorship process in the context of psychiatry residency....

The Formation of Marijuana Risk Perception in a Population of Substance Abusing Patients

Samuel T. Wilkinson, Gerrit I. Schalkwyk, Larry Davidson, Deepak C. D’Souza

Psychiatric Quarterly > 2016 > 87 > 1 > 177-187

Risk perception has been shown to be protective with regard to marijuana use. Notably, the risk perception of marijuana in individuals with substance abuse problems varies significantly from that of the general public. Understanding how risk perception is formed in substance users could explain these differences and help predict the consequences of policy changes. Using this framework, we explored...

Varieties of Misdiagnosis in ASD: An Illustrative Case Series

Gerrit I. Schalkwyk, Francesco Peluso, Zheala Qayyum, James C. McPartland, more

Journal of Autism and Developmental Disorders > 2015 > 45 > 4 > 911-918

The relationship between autism spectrum disorders (ASD) and psychotic disorders (PD) is a focus of continued interest. There are substantial conceptual and clinical difficulties associated with diagnosing comorbid PD in individuals who have ASD. In this case series, we report on five cases where adolescents with previously diagnosed ASD were also diagnosed as psychotic. In each case, we found that...

Reduction of Aggressive Episodes After Repeated Transdermal Nicotine Administration in a Hospitalized Adolescent with Autism Spectrum Disorder

Gerrit I. Schalkwyk, Alan S. Lewis, Zheala Qayyum, Kourtney Koslosky, more

Journal of Autism and Developmental Disorders > 2015 > 45 > 9 > 3061-3066

Aggression remains a major cause of morbidity in patients with autism spectrum disorder (ASD). Current pharmacotherapy for aggression is not always effective and is often associated with morbidity. Nicotinic acetylcholinergic neurotransmission may play a prominent role in ASD pathophysiology based on human and animal studies, and preclinical studies show nicotine administration can reduce aggression-related...
