Asperger syndrome information and therapy, changed to DMDD

A specific overlap between Asperger syndrome (AS) and nonverbal learning difficulties (NLD) has been proposed, based on the observation that, as a group, people with AS tend to have significantly higher verbal IQ (VIQ) than performance IQ (PIQ), one of the core features of NLD.

Upon awakening, there is normally a surge in cortisol, a steroid hormone produced by the adrenal gland and released in response to stress. This response is absent in adolescent boys with Asperger syndrome, which may explain some of the symptoms of the condition, such as the need for routine and resistance to change. Among other functions, the ability to adapt to change is controlled by the hypothalamic-pituitary-adrenal axis, which controls the dramatic increase in cortisol upon awakening, referred to as "the cortisol awakening response." The cortisol awakening response is a robust and reproducible neuroendocrine phenomenon which has been positively correlated with psychological and physical well-being. Dr. Mark Brosnan from University of Bath and colleagues say their research points to a lack of response in the hypothalamic-pituitary-adrenal axis in individuals with Asperger syndrome, which may help explain why these individuals have difficulties if there are minor changes in their routine or environment. In the study, the investigators measured the cortisol in saliva of 20 adolescent males with Asperger syndrome and 18 age-matched controls at the time of awakening and 30 minutes later. While a significant cortisol awakening response was clearly evident in the control group, this was not the case in the Asperger group. Psychoneuroendocrinology 2009.

J Autism Dev Disorders. 2016. Asperger Syndrome and Schizophrenia: A Comparative Neuropsychological Study. There has been an increasing interest in possible connections between autism spectrum disorder (ASD) and schizophrenia in the last decade. Neuropsychological comparison studies have, however, been few. The present study examined similarities and differences in intellectual and executive functioning between adults with Asperger syndrome (AS) and adults with schizophrenic psychosis (SP). A group with AS and a group with SP were assessed neuropsychologically with WAIS-III and D-KEFS. Similarities were found between groups, as displayed by an uneven cognitive profile, limitations in working memory, processing speed and some aspects of executive functioning. Full Scale IQ was higher in the AS group. These results add to the current research illuminating similarities and differences between ASD and schizophrenia on a cognitive level.
