Autism spectrum disorder (ASD) comprises alterations in brain anatomy and physiology that ultimately affect information processing and behavior. In most cases, autism is considered idiopathic, involving alterations in numerous genes whose functions are not extensively documented. We evaluated the C58/J mouse strain as an idiopathic model of ASD, emphasizing synaptic transmission as the basis of information processing.

Local protein synthesis (LPS) in axons is now recognized as a physiological process, participating both in the maintenance of axonal function and diverse plastic phenomena. In the last decades of the 20th century, the existence and function of axonal LPS were topics of significant debate. Very early, axonal LPS was thought not to occur at all and was later accepted to play roles only during development or in response to specific conditions.

Exposure to psychosocial stress during pregnancy has been associated with the emergence of neurodevelopmental and neuropsychiatric disorders in offspring. The placenta is known to orchestrate various functions that are essential for normal fetal development, including the brain. It has therefore been postulated that alterations in such functions, and downstream signaling, have the potential to dramatically affect brain developmental trajectories and contribute to adverse neurodevelopmental outcomes.

The Aberrant Behavior Checklist (ABC) was originally developed to evaluate interventions, and is a well-established assessment tool for challenging behaviours in people with intellectual disabilities and autistic people. However, whether the ABC displays longitudinal measurement invariance (i.e.

There are differing opinions in the literature regarding the cardiovascular safety of long-term methylphenidate use. Studies suggest that the drug may increase the risk of hypertension, myocardial infarction, ventricular arrhythmia, sudden cardiac death, cardiomyopathy, heart failure (HF), pulmonary hypertension, and stroke.
