Sustained attention in the face of distractors: a study of children with Rett syndrome - Rose SA, Wass S, Jankowski JJ, Feldman JF, Djukic A.

OBJECTIVE: The object of the present study is to advance our understanding of the cognitive profile of Rett syndrome (RTT), an X-linked neurodevelopmental disorder caused by mutations in the MECP2 gene. We focus on sustained attention, which plays a critic...

AbstractMeCP2 is an X-linked gene; its mutation causes Rett Syndrome (RTT), a severe neurodevelopmental disability that affects mainly girls. Acting as a transcription factor, the MeCP2 protein is able to regulate several hormone-related genes, such as the thyroid hormones (TH), which are known to play an important role in the development of the central nervous system (CNS). Although only a few studies have associated RTT and TH, TH deficit can lead to neurological deregulation by triggering functional deficiencies during adulthood. Here, we used human-induced pluripotent stem cell (iPSC) to generate MeCP2-knockout neurona...

Abstract Genes and environmental stimuli cooperate in the regulation of brain development and formation of the adult neuronal architecture. Genetic alterations or exposure to perturbing environmental conditions, therefore, can lead to altered neural processes associated with neurodevelopmental disorders and brain disabilities. In this context, environmental enrichment emerged as a promising and noninvasive experimental treatment for favoring recovery of cognitive and sensory functions in different neurodevelopmental disorders. The aim of this review is to depict, mainly through the much explicative examples of amb...

AbstractPurpose of ReviewTo summarize findings about the emergence and characteristics of canonical babbling in children with late detected developmental disorders (LDDDs), such as autism spectrum disorder, Rett syndrome, and fragile X syndrome. In particular, we ask whether infants ’ vocal development in the first year of life contains any markers that may contribute to earlier detection of these disorders.Recent FindingsOnly a handful studies have investigated canonical babbling in infants with LDDDs. With divergent research paradigms and definitions applied, findings on the onset and characteristics of canonical b...

Objective: We reviewed medical records and conducted a nationwide survey to characterize the clinical features and determine the prevalence of biliary tract disease in girls and women with Rett syndrome (RTT). Methods: Sixty-two individuals with RTT and biliary tract disease were identified from the membership of Rett Syndrome Organization and patient files of the principal investigator. Medical records of 46 individuals were reviewed for presenting features, diagnostic tests, and treatment outcomes of biliary tract disease. We designed a questionnaire that probed the frequency of risk factors and treatment outcomes o...

Inputs from the ventral hippocampus (vHIP) to the medial prefrontal cortex (mPFC) are implicated in several neuropsychiatric disorders. Here, we show that the vHIP-mPFC projection is hyperactive in theMecp2knockout mouse model of the autism spectrum disorder Rett syndrome, which has deficits in social memory. Long-term excitation of mPFC-projecting vHIP neurons in wild-type mice impaired social memory, whereas their long-term inhibition in Rett mice rescued social memory deficits. The extent of social memory improvement was negatively correlated with vHIP-evoked responses in mPFC slices, on a mouse-per-mouse basis. Acute m...

Conclusions: These preliminary results reveal decreased uptake of [11C]UCB-J in the Rett syndrome mouse model are consistent with the hypothesis that the loss of Mecp2 gene may result in decreased synaptic density in the cerebral cortex. Studies are ongoing to increase the sample size that may inform future investigation into whether [11C]UCB-J imaging can serve as a valid biomarker in individuals with Rett syndrome.

Publication date: Available online 18 May 2019Source: Neuroscience &Biobehavioral ReviewsAuthor(s): Livia Cosentino, Daniele Vigli, Francesca Franchi, Giovanni Laviola, Bianca De FilippisAbstractRett syndrome (RTT) is a rare neurological disorder primarily affecting females, causing severe cognitive, social, motor and physiological impairments for which no cure currently exists. RTT clinical diagnosis is based on the peculiar progression of the disease, since patients show an apparently normal initial development with a subsequent sudden regression at around 2 years of age. Accumulating evidences are rising doubts rega...
