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.

Microbiome differences in autism reflect dietary preferences, says study

Earlier studies suggest that autism spectrum disorder (ASD) might be partly due to differences in the gut microbiota composition.

Novel algorithm pinpoints genes associated with related genetic diseases

Scientists recently discovered almost two dozen genes that contribute to heart defects while analyzing genetic data from individuals.

Genetic liability to mental health conditions may affect a person's choice of residence

Living in cities has been highlighted as an environmental risk factor for schizophrenia and, to a lesser extent, other mental health conditions. However, few studies have explored genetic effects on the choice of residence.

New insight into how neurons and astrocytes work together to form healthy synapses

Brain cells called astrocytes play a key role in helping neurons develop and function properly, but there's still a lot scientists don't understand about how astrocytes perform these important jobs.

Study analyzes walking movements to detect nervous system disorders

Scientists from Rutgers University linked the genetic disorders Fragile X and SHANK3 deletion syndrome to walking patterns.

Study finds greater facial asymmetry in parents of autistic individuals

Recent research in Western Australia employs high-tech 3D facial scans to provide better knowledge of the genetic causes of autism.

UMSOM study suggests a genetic basis behind instantaneous human compatibility

Have you ever met someone you instantly liked, or at other times, someone who you knew immediately that you did not want to be friends with, although you did not know why?

New research identifies a master timekeeper for the brain's circadian clock

A gene called Npas4, already known to play a key role in balancing excitatory and inhibitory inputs in brain cells, appears to also be a master timekeeper for the brain's circadian clock, new research led by UT Southwestern scientists suggests.

Study describes a new method for identifying sperm mutations that can cause disease in children

Throughout development, life and the processes of aging, all human cells accumulate mutations, resulting in what is called mosaicism, a condition in which different cells in the same person have different DNA sequences or genetic makeup.

Study identifies rare inherited variants that implicate new autism candidate risk genes

Scientists have found a rare class of genetic differences that are transmitted from parents without autism to their children affected with autism.

Study identifies a signaling protein that controls the assembly of mitochondria

Scientists from the University of Freiburg have identified a signaling protein that regulates the assembly of human cellular “power plants.”

Study shows astrocytes induce sex differences during brain development

Scientists have found that when brain cells develop, they may find various ways to link with each other based on sex.

Study reveals neurotransmitter releases impairments in schizophrenia patients

A research team revealed that neurotransmitter release in the brain is impaired in patients with schizophrenia who possess a rare, single-gene mutation.

Study reveals causal gene in autism model mice with copy number variation

A new study has unraveled a causal gene (Necdin, NDN) in autism model mice that exhibit the chromosomal abnormality known as copy number variation.

Scientists reveal key role of glial protein in building the brain

When we think of the brain, we think of neurons. But much of the brain is made of non-neuronal cells called glial cells, which help regulate brain development and function.

Study reveals a preliminary genetic link to dyspraxia

Researchers from Oxford Brookes University have found certain genes that can potentially reveal critical information about the biology of developmental coordination disorder (DCD), also called dyspraxia.

Nutritional supplement can help bolster key functions for people with brain disorders

An international subject pool was studied to confirm the effectiveness of a whole food complete vitamin and meal replacement product, IQed. The article, co-authored by Lisa Geng; Francine Hamel, EdD, SLP-CCC; Doreen Lewis, Ph.D., appeared in the peer-reviewed journal, Alternative Therapies (Altern Ther Health Med 2021 Mar;27(2):11-20).
