Genomind, a personalized medicine company, has released a statement in response to the National Institute of Mental Health’s (NIMH) announcement by Director Dr. Thomas Insel that the organization will be re-orienting its research away from DSM categories, supporting the move and its potential to influence improved treatment of patients with mental disorders.

Magnetic resonance imaging (MRI) measurements of atrophy in an important area of the brain are an accurate predictor of multiple sclerosis (MS), according to a new study published online in the journal Radiology. According to the researchers, these atrophy measurements offer an improvement over current methods for evaluating patients at risk for MS.

Scientists at Washington University School of Medicine in St. Louis have helped identify many of the biomarkers for Alzheimer's disease that could potentially predict which patients will develop the disorder later in life. Now, studying spinal fluid samples and health data from 201 research participants at the Charles F. and Joanne Knight Alzheimer's Disease Research Center, the researchers have shown the markers are accurate predictors of Alzheimer's years before symptoms develop.

The Parkinson's Progression Markers Initiative (PPMI), a landmark biomarker clinical study, has completed enrollment of its initial 600-member cohort of Parkinson's patients and controls, and will launch additional study cohorts to leverage the existing PPMI infrastructure and evaluate multiple potential biomarkers for Parkinson's disease (PD). The first of these new cohorts launches today and will investigate risk factors for PD that may enable diagnosis before the onset of motor symptoms.

Eli Lilly and Company (NYSE: LLY) recently announced it has acquired two investigational positron emission tomography (PET) tracers from Siemens Medical Solutions USA, Inc. The tracers are intended to image tau (or neurofibrillary) tangles in the brain, one of two known hallmarks of Alzheimer's disease. Based on studies of samples obtained at autopsy, the amount and location of tau tangles in an Alzheimer's disease patient's brain is thought to correlate with the severity of the disease.

Dr. Tom Hudson, President and Scientific Director of the Ontario Institute for Cancer Research (OICR) recently announced a collaboration with Janssen Inc. to find and test new biomarkers to identify patients with hormone resistant prostate cancer at high risk for disease progression and biomarkers of response to therapy. These biomarkers could lead to more personalized treatments and fewer side effects for prostate cancer patients.
