Several new genetic variants associated with schizophrenia lie in regions important for immune function and associated with autism. This suggests that both disorders stem partly from abnormal activation of the immune system, say some researchers.

A common variant of a gene called CACNA1G — which makes a channel that helps regulate calcium flow between cells — may increase the risk of developing autism, according to research published in Molecular Psychiatry.

Applying an emerging technique that combines genetic data and brain scans, researchers have identified two new genes involved in schizophrenia. The method, called ‘imaging genetics’, holds promise for linking genes to brain function in complex psychiatric disorders, including autism.

A new slow-release form of the drug risperidone ― an antipsychotic given to people with schizophrenia, autism and other psychiatric conditions ― lasts in the blood days instead of hours, according to research presented today at the Society for Neuroscience meeting.

The molecular mechanisms underlying synaptic plasticity ― the ability of neurons to change the strength of their connections ― can vary across different inhibitory neural circuits as much as they can vary across excitatory neural circuits, according to research presented this morning at the Society for Neuroscience meeting.

Targeting epigenetic mechanisms may offer potential new therapies for people with developmental disorders including autism, researchers said today at the Society for Neuroscience meeting.

Schizophrenia may be a consequence of neuronal birth gone awry, according to unpublished research presented today at the Society for Neuroscience conference.

Even as I type this, thousands of neuroscientists are descending on Washington D.C. for an annual event that is almost beyond description. An estimated 36,000 people are expected to attend Neuroscience 2008, this yearʼs meeting of the Society for Neuroscience, hobnob, listen to lectures, present posters and down drinks at the many social events.

Rare, spontaneous mutations could account for at least ten percent of cases of schizophrenia, according a study published online last week.

Are older fathers more likely to have children with autism? A series of epidemiological studies is giving credence to the idea, suggesting that, with age, sperm may accumulate damage that increases risk in the next generation.
