Autism female

Megan M Wickens, Debra A Bangasser, Lisa A Briand
Alterations in glutamate, the primary excitatory neurotransmitter in the brain, are implicated in several psychiatric diseases. Many of these psychiatric diseases display epidemiological sex differences, with either males or females exhibiting different symptoms or disease prevalence. However, little work has considered the interaction of disrupted glutamatergic transmission and sex on disease states. This review describes the clinical and preclinical evidence for these sex differences with a focus on two conditions that are more prevalent in women: Alzheimer's disease and major depressive disorder, and three conditions that are more prevalent in men: schizophrenia, autism spectrum disorder, and attention deficit hyperactivity disorder...

Prenatal exposure to citalopram (CTM), an antidepressant drug, has been associated with altered behavior, including autism-like symptoms in both human and rodent offspring. However, the neurological basis underlying these abnormal behaviors is not well understood. Here, we examined behavioral, morphological, and biochemical alterations in the male and female offspring of C57BL/6 mouse mothers that had been exposed to CTM during the last trimester of gestation. We observed abnormal behavior such as anxiety, altered locomotion and disordered social interactions in 2-5 month old offspring with prenatal CTM exposure...

It is suggested that testosterone may play a part in the higher prevalence of Autism Spectrum Disorder (ASD) in males compared to females. Previous studies have reported elevated postnatal testosterone levels in children and women with ASD but not in men. We compared levels of salivary testosterone across 67 undergraduate males (Mage 19.5 yrs, SD 1.92) selected for low, mid-range and high levels of autistic traits assessed using the Autism-spectrum Quotient. Analyses revealed no significant differences in testosterone concentrations across the three groups...

The transcriptome sequencing data of valproic acid (VPA) model of autism and control rats are presented. VPA model of autism was induced by a single intraperitoneal injection of 600 mg/kg sodium valproic acid to female rats at day 12.5 post-conception, and the control rats were injected with saline. Male offspring of VPA- or saline-injected dams from different litters were sacrificed on PND 35 ( n = three rats/three litters/group). Prefrontal cortex was dissected from both hemispheres, and RNA was isolated...

BACKGROUND- Children with Autism Spectrum Disorder (ASD) demonstrate a physiological imbalance between free radicals, resultant from oxidative stress, and antioxidants. Oxidative stress is linked to the pathogenesis of this neurocognitive disorder. The aim of this pilot feasibility study was to examine the effect of consumption of high concentration antioxidant cacao on behavior of children with ASD. METHODS- This was a 4-week pre-test post-test experimental pilot study of high antioxidant cacao and children with ASD...

OBJECTIVE: In different cohorts, 5%-30% of individuals with autism spectrum disorder (ASD) also have epilepsy. The high co-occurrence of these disorders suggests that a common mechanistic link may exist. The underlying pathophysiology of this comorbidity remains unknown. To investigate the mechanism(s) involved in the pathogenesis of ASD and epilepsy, we developed and validated a novel mouse model that concurrently exhibits hallmark features of both disorders. METHODS: We utilized inbred BTBR T+ Itpr3tf/J (BTBR) mice that exhibit the core behavioral characteristics of ASD (ie, impaired sociability, altered vocalizations, and restricted interests)...

Background: Autism is a challenging neurodevelopmental disorder. Previous clinical observations suggest altered sedation requirements for autistic children. Our study aimed to test this observation experimentally with an animal model and, to explore its possible mechanisms. Methods: Eight adult pregnant female Sprague Dawley rats were randomly selected into two groups. Four were injected with intraperitoneal sodium valproate on the gestational day 12 and four were injected with normal saline...

Purpose: The ability to repair breakdowns in communication is an important pragmatic language skill that helps to maintain clear and meaningful interactions. Examining this ability in genetically based neurodevelopmental disabilities in which pragmatics are affected can provide important information about the precise pragmatic skills impacted across different populations and also help to identify core mechanisms underlying pragmatic impairment that may inform tailored interventions. Method: Individuals with idiopathic autism spectrum disorder (ASD-O; n = 40), fragile X syndrome with comorbid autism spectrum disorder (FXS-ASD; n = 62), FXS without ASD (FXS-O; n = 38), Down syndrome (DS; n = 43), and typical development (TD; n = 42) completed a picture description task in which an examiner prompted for clarification repeatedly to elicit communication repair attempts...

Background: Sex differences in autistic symptomatology are believed to contribute to the mis- and missed diagnosis of many girls and women with an autism spectrum condition (ASC). Whilst recent years have seen the emergence of clinical and empirical reports delineating the profile of young autistic girls, recognition of sex differences in symptomatology in adulthood is far more limited. Methods: We chose here to focus on symptomatology as reported using a screening instrument, the Ritvo Autism Asperger Diagnostic Scale-Revised (RAADS-R)...

Recent studies have determined that the microbiome has direct effects on behavior, and may be dysregulated in neurodevelopmental conditions. Considering that neurodevelopmental conditions, such as autism, have a strong genetic etiology, it is necessary to understand if genes associated with neurodevelopmental disorders, such as Shank3, can influence the gut microbiome, and if probiotics can be a therapeutic tool. In this study, we have identified dysregulation of several genera and species of bacteria in the gut and colon of both male and female Shank3 KO mice...

Recent studies suggest that circumscribed interests (CI) in females with Autism Spectrum Disorder (ASD) may align more closely with interests reported in typical female development than those typically reported for ASD males. We used eye-tracking to quantify attention to arrays containing combinations of male, female and neutral images in elementary-aged males and females with and without ASD. A number of condition × sex effects emerged, with both groups attending to images that corresponded with interests typically associated with their biological sex...

Stimulation of the immune system during pregnancy, known as maternal immune activation (MIA), can cause long-lasting neurobiological and behavioral changes in the offspring. This phenomenon has been implicated in the etiology of developmental psychiatric disorders, such as autism and schizophrenia. Much of this evidence is predicated on animal models using bacterial agents such as LPS and/or viral mimics such as Poly I:C, both of which act through toll-like receptors. However, fewer studies have examined the role of direct activation of maternal T-cells during pregnancy using microbial agents...

Background: Motor impairments are amongst the earliest and most consistent signs of autism spectrum disorders (ASD) but are not used as diagnostic criteria. In addition, the relationship between motor and cognitive impairments and their respective neural substrates remain unknown. Methods: Here, we aimed at determining whether a well-acknowledged animal model of ASD, the valproic acid (VPA) model, displays motor impairments and whether they may correlate with social deficits and neuronal loss within motor brain areas...

Cytoplasmic FMRP interacting proteins 1 and 2 (CYFIP1/2) have been previously shown to be associated with central nervous system (CNS) disorders such as autism spectrum disorder (ASD). Moreover, dysregulation of their expression levels results in disturbances in CNS maturation and neuronal interconnections. In the present study, we compared expression levels of CYFIP1/2 in peripheral blood of 30 ASD patients and 41 healthy subjects by means of real time PCR. Expression analysis showed significant over-expression of CYFIP1/2 in ASD patients compared with healthy subjects (Fold change = 3...
