Autism spectrum disorder (ASD) is a serious neurodevelopmental disorder, associated with autonomic dysregulation. However, the pathomechanism leading to autonomic abnormalities is still unclear. The aim of this study was to assess autonomic nervous system (ANS) activity during baseline in homogenous group of autistic children using electrodermal activity (EDA), as an index of sympathetic activity and short-term heart rate variability (HRV) reflecting predominantly cardiac vagal control. Fifteen ASD boys and 15 healthy age-matched boys at the age of 7-15 years were examined. The continuous EDA and ECG were recorded during resting phase in a supine position. Evaluated parameters: EDA amplitude (microS), RR interval, spectral power, peak frequency and power spectral density in low (LF-HRV: 0.04-0.15 Hz) and high-frequency (HF-HRV: 0.15-0.4 Hz) bands of HRV spectral analysis. In ASD group we found significantly shortened RR intervals (729+/-20 ms vs. 843+/-30 ms, p=0.005), lower mean EDA (0.66+/-0.13 microS vs. 1.66+/-0.42 microS, p=0.033), reduced spectral activity and power spectral density in HF-HRV compared to controls (2.93+/-0.12 ms(2) vs. 3.38+/-0.10 ms(2), p=0.01; 4.12+/-0.10 ms(2)/Hz vs. 4.56+/-0.11 ms(2)/Hz, p=0.008, respectively). We suggest that impairment in resting autonomic regulation associated with ASD could represent an important pathomechanism leading to potential cardiovascular complications in ASD.

The present study examined the effects of a culturally adapted intervention, ¡Iniciando! la Adultez, on sleep and health-related quality of life (HRQoL) in Latino young adults with autism spectrum disorder (ASD) and their Spanish-speaking parents. The intervention targeted the transition to adulthood, a period associated with increased challenges in sleep and HRQoL, particularly for underserved Latino populations. Participants included 26 young adults and 38 parents who completed assessments at baseline and post-treatment.

Repetitive behaviors are the hallmark of many neuropsychiatric disorders, including Tourette syndrome (TS), obsessive-compulsive disorder (OCD), and autism spectrum disorder (ASD). Tics, compulsions, and stereotypies may appear similar and can be difficult to disentangle. This review addresses similarities and differences between these behaviors including clinical presentations, neuroimaging, genetics, and treatment paradigms in order to clarify the relationship between these disorders.

Extensive researches illuminate a potential interplay between immune traits and psychiatric disorders. However, whether there is the causal relationship between the two remains an unresolved question. We conducted a two-sample bidirectional mendelian randomization by utilizing summary data of 731 immune cell traits from genome-wide association studies (GCST90001391-GCST90002121)) and 11 psychiatric disorders including attention deficit/hyperactivity disorder (ADHD), anxiety disorder, autism spectrum disorder (ASD), bipolar disorder (BIP), anorexia nervosa (AN), major depressive disorder (MDD), obsessive-compulsive disorder (OCD), Tourette syndrome (TS), post-traumatic stress disorder (PTSD), schizophrenia (SCZ), and substance use disorders (cannabis) (SUD) from the Psychiatric Genomics Consortium (PGC).

Neurodiversity, encompassing conditions such as autism spectrum disorder, attention-deficit/hyperactivity disorder, and dyslexia, represents a significant and often under-recognized segment of the population, including within science, technology, engineering, mathematics, and medicine fields like medicine. Neurodiverse individuals possess unique skills, including enhanced creativity, analytical thinking, and meticulous attention to detail, which are valuable in health care professions. However, failure to recognize and support these individuals can result in missed opportunities, social isolation, and mental health challenges.

Cell fate decisions during cortical development sculpt the identity of long-range connections that subserve complex behaviors. These decisions are largely dictated by mutually exclusive transcription factors, including CTIP2/Bcl11b for subcerebral projection neurons and BRN1/Pou3f3 for intra-telencephalic projection neurons. We have recently reported that the balance of cortical CTIP2-expressing neurons is altered in a mouse model of DDX3X syndrome, a female-biased neurodevelopmental disorder associated with intellectual disability, autism spectrum disorder, and significant motor challenges.
