Autism News and Research

RSS

Autism (sometimes called “classical autism”) is the most common condition in a group of developmental disorders known as the autism spectrum disorders (ASDs). Autism is characterized by impaired social interaction, problems with verbal and nonverbal communication, and unusual, repetitive, or severely limited activities and interests. Other ASDs include Asperger syndrome, Rett syndrome, childhood disintegrative disorder, and pervasive developmental disorder not otherwise specified (usually referred to as PDD-NOS). Experts estimate that three to six children out of every 1,000 will have autism. Males are four times more likely to have autism than females.

Study shows autism spectrum disorder is related to changes in the gut microbiome

According to a new study, autism spectrum disorder is associated with changes in the gut microbiome.

Unique mini-microscope enables imaging of brain activity in freely moving mice

Researchers from the University of Minnesota Twin Cities College of Science and Engineering and Medical School have developed a unique head-mounted mini-microscope device that allows them to image complex brain functions of freely moving mice in real time over a period of more than 300 days.

Innovative computational model of cells could help better understand neurodevelopmental disorders

For a long time, researchers have attempted to gain better insights into the development of the cerebral cortex and its layers, since pathologies are associated with this process.

Scientists provide a complete phenotypic landscape of SCN2A-related disorders

Researchers from Children's Hospital of Philadelphia (CHOP) affiliated with the CHOP Epilepsy Neurogenetics Initiative (ENGIN) have compiled a complete genetic and clinical analysis of more than 400 individuals with SCN2A-related disorder, which has been linked to a variety of neurodevelopmental disorders, including epilepsy and autism.

Enzyme in fruit fly larvae plays key role in waking up brain stem cells

Researchers studying an enzyme in fruit fly larvae have found that it plays an important role in waking up brain stem cells from their dormant 'quiescent' state, enabling them to proliferate and generate new neurons.

Light-activated protein can be used to study single synapses of neurons

Neurons are the primary cells of the nervous system, and the signals that are transmitted between them are responsible for all our actions and our cognitive ability.

Scientists implicate disruption in prenatal neurogenesis in the development of autism

A new study of autism risk genes by UC San Francisco and UC Berkeley scientists implicates disruption in prenatal neurogenesis - a process in which specialized "progenitor" cells give rise to new brain cells - in the development of autism spectrum disorders (ASDs).

Study shows strong link between genetic changes and cerebral palsy

Scientists have identified a strong connection between genetic modifications known to cause cerebral palsy and neurodevelopmental disabilities.

KAIST researchers identify mechanism underlying plasticity in adult brains

Developing brains constantly sprout new neuronal connections called synapses as they learn and remember. Important connections — the ones that are repeatedly introduced, such as how to avoid danger — are nurtured and reinforced, while connections deemed unnecessary are pruned away.

Researchers create 3D miniature organs that precisely mimic human tissues

Organoids are tissues that look like organs and are extracted from stem cells cultured in laboratories. They are usually known as miniature organs.

Researchers test effects of weedkiller on wildlife

Prolonged exposure to environmentally relevant concentrations of the weedkiller Roundup causes significant harm to keystone species according to new research at the University of Birmingham.

Microglia surveillance helps prevent seizure activity in the brain

An important part of the brain's immune system, cells called microglia constantly extend and retract "branches" from their cell body to survey their environment.

Researchers develop new tool to study genes associated with autism spectrum disorder

Researchers have developed technology to analyze the function of different types of genes found in many types of cells in a living organism, at the same time.

Scientists identify key source of sensory perception

The brain encodes information collected by our senses. However, to perceive our environment and to constructively interact with it, these sensory signals need to be interpreted in the context of our previous experiences and current aims.

Bacterial microbes in the human gut could help diagnose and treat autism spectrum disorder

Every year, 1 out of 54 children in the United States is diagnosed with autism spectrum disorder, and the count has been increasing, reports the Centers for Disease Research.

Astrocytes regulate inhibitory synapses by binding to neurons

In the orchestra of the brain, the firing of each neuron is controlled by two notes--excitatory and inhibitory-- that come from two distinct forms of a cellular structure called synapses.

Researchers identify genes associated with autism spectrum disorder

The lack of some genes in the BEC/TCEAL cluster could be related to some alterations associated with the autism spectrum disorder, according to a preclinical study published in the journal Genome Biology, and led by Professor Jordi Garcia Fernàndez, from the Faculty of Biology and the Institute of Biomedicine of the University of Barcelona (IBUB), and researcher Jaime Carvajal, from the Andalusian Centre for Developmental Biology - University Pablo de Olavide (CSIC-UPO).

High folic acid levels during pregnancy affect brain development of mouse embryos

A UC Davis MIND Institute study of pregnant mice found that high amounts of folic acid during pregnancy harmed the brain development of embryos.

Mouse model reveals neurons responsible for guiding adaptive behavior

Humans, like other animals, have the ability to constantly adapt to new situations. Researchers at the Brain Research Institute of the University of Zurich have utilized a mouse model to reveal which neurons in the brain are in command in guiding adaptive behavior.

Study shows how neural circuits are refined in response to sensory cues

According to a study published in the Neuron journal in September 2020, immune cells play a surprising role in fine-tuning the neural circuits of the brain.
