Enlarged perivascular spaces in infant brains linked to autism risk
Infants with enlarged perivascular spaces have a more than two-fold greater chance of developing autism compared with infants with normal perivascular spaces, according to researchers from the University of North Carolina in Chapel Hill."These results suggest that perivascular spaces could serve as an early marker for autism," said study lead author Dea Garic, PhD, in a statement released January 2 by the university.Every six hours, the brain expels a wave of cerebrospinal fluid (CSF) that flows through perivascular spaces; this fluid mitigates the buildup of neuroinflammatory proteins, such as amyloid beta. The cleansing ...

A review of the use of psychotropic medication to address challenging behaviour in neurodevelopmental disorders - Valdovinos MG, Epperson C, Johnson C.
Engagement in challenging behaviour (e.g., aggression, self-injury) is reported to occur in neurodevelopmental disorders such as intellectual disabilities (ID), autism spectrum disorder (ASD), and fragile X syndrome (FXS). Common interventions to address t... (Source: SafetyLit)

Why Does He Rock His Body?
Discussion
Stereotypies are “…patterned, repetitive, purposeless, involuntary movements that are also rhythmic and continual and tend to change little over time.” They occur at all times of the day, and can get worse with stress or heightened emotions including happiness. Stereotypies more often occur in children with developmental disabilities (up to 61%), sensory impairments (e.g. blindness) or social deprivation. They can be present more often in patients with autism (up to 88%). They can be seen in ~7% of normally developing children too. Their onset is before age 3 years and tend to improve over year...

Upstate researcher makes discovery in the Fragile X syndrome, receives funding to research genomic defects
Fragile X syndrome is a genetic disorder that occurs when mutations in the FMR1 gene cause the absence or loss of function of FMRP, a protein needed for brain development. (Source: SUNY Upstate Medical)

What Are Some Etiologies for Intellectual Disability?
Discussion
“Intellectual disability (ID) is a neurodevelopmental disorder that is characterized by deficits in both intellectual functioning and adaptive function whose onset is in the development period.” Global developmental delay (GDD) is used to describe children from 0-5 years old with significant delays in 2 or more developmental areas. These delays may be transient but up to 2/3 of children with GDD will have ID. Overall 1-3% of the general population has ID which makes it very common.
Most children with GDD/ID are identified because of delays in meeting milestones or general academic achievement. ID pat...

Genome-editing tool TALEN outperforms CRISPR-Cas9 in tightly packed DNA
(University of Illinois at Urbana-Champaign, News Bureau) Researchers used single-molecule imaging to compare the genome-editing tools CRISPR-Cas9 and TALEN. Their experiments revealed that TALEN is up to five times more efficient than CRISPR-Cas9 in parts of the genome, called heterochromatin, that are densely packed. Fragile X syndrome, sickle cell anemia, beta-thalassemia and other diseases are the result of genetic defects in the heterochromatin. (Source: EurekAlert! - Medicine and Health)

Zynerba provides progress report on its potential Fragile X syndrome therapy
Zynerba Pharmaceuticals, a developer of synthetic and transdermal cannabinoid therapies for rare neuropsychiatric disorders, said Thursday it expects to begin a "pivotal" late-stage clinical trial of its experimental Fragile X syndrome therapy Zygel late next year.
The leaders of the 13-year-old Devon company said they believe positive results from the trial, to confirm previous study results, would be sufficient to support the submission of a new drug application for Zygel to treat Fragile X.
