Depression Genetics Suffer Major Setback
Jul 6th
A 2003, a paper by Caspi and colleagues offered tantalizing clues about the genetics of depression, in what was widely-acclaimed as a breakthrough paper for psychiatric genetics as a whole. Now, new research by Katleeen Merikangas at the National Institute of Mental Health queries the results taking us, according to Science magazine, back to the drawing board.
What was so important about Caspi et al.? The original Caspi paper of 2003 looked at a sample of 847 New Zealanders, and examined whether gene-environment interactions might lead to depression. The research team were particularly interested in genes involved in serotonin transportation and reception - serotonin has More >
Psychosis – New Study Links Gene Variant to Brain Structures
May 12th
A study published in last week’s Science magazine shows how genomic science and neuroimaging can be combined to deliver insights into cognitive disorders. As well as providing an intriguing look into the neurobiology of psychosis, the study reflects a growing trend toward inter-disciplinary research in the neurosciences,
What did the study show?
Psychosis is a disordered cognitive state that can include disorganized thoughts, delusions, or hallucinations. It is a common symptom of schizophrenia and has been linked to a number of brain areas, including the the dorsolateral prefrontal cortex (DLPFC) and the hippocampus. Schizophrenia is also strongly associated with a number of genes, and More >
