Researchers have discovered and validated a blood test that can predict with greater than 90 percent accuracy if a healthy person will develop mild cognitive impairment or Alzheimer’s disease within three years. It is the first known published report of blood-based biomarkers for preclinical Alzheimer’s disease.
Google Glass could potentially save lives, especially in isolated or far-flung locations, say...
A DNA test of a pregnant woman's blood is more accurate than current methods of screening for...
Substance P and calcitonin gene-related peptide are the main neuropeptides in peripheral nerve ganglia, which can anterogradely transmit nociceptive information to the central nervous system. Findings published in Neural Regeneration Research suggest that these neuropeptides may possibly serve as an index for evaluating early peripheral nerve injury.
For the first time, researchers have confirmed an association between a common magnetic resonance imaging (MRI) contrast agent and abnormalities on brain MRI, according to a new study.
A simple blood test will soon be able to catch the vast majority of a group of chronic blood cancers, a new study reveals. The scientists also identified a new gene, CALR, which is altered in 40 percent of blood disorders.
A new microchip-based device may greatly simplify the monitoring of patients’ response to treatment for ovarian cancer— the most lethal form of gynecologic cancer— and certain other malignancies.
As you step outdoors into the bright sunshine, your pupils automatically contract. Scientists are making use of how this "pupil reflex" is connected to the brain as a potential new way of testing the severity of multiple sclerosis (MS).
Using a special MRI technique designed for studies of sleeping infants, researchers have found that infants who carry a gene associated with an increased risk for Alzheimer’s disease tend to have differences in brain development compared to infants who do not carry the gene.
Women who are members of families with BRCA2 mutations but who test negative for the family-specific BRCA2 mutations are still at greater risk for developing breast cancer compared with women in the general population, according to a new study.
The U.S. Food and Drug Administration allowed marketing of four diagnostic devices that can be used for high throughput gene sequencing, often referred to as “next generation sequencing” (NGS). These instruments, reagents and test systems allow labs to sequence a patient’s DNA.
A new blood biomarker correctly predicted which concussion victims went on to have white matter tract structural damage and persistent cognitive dysfunction following a mild traumatic brain injury (mTBI).
Scientists have discovered that the presence of a specific protein can distinguish between prostate cancers that are aggressive and need further treatment from those that may never seriously harm the patient.
Washington University School of Medicine in St. Louis now offers genetic testing to help diagnose and treat patients with heart disorders that can lead to sudden death.
Using scores obtained from cognitive tests, researchers think they have developed a model that could help determine whether memory loss in older adults is benign or a stop on the way to Alzheimer’s disease.
To better understand and one day provide improved treatments for depression, addiction and anxiety, researchers are using tiny, electronic devices to identify and map neural circuits in the brain.
For the first time, scientists have used new technology which analyses the whole genome to find the cause of a genetic disease in what was previously referred to as “junk DNA.”
With almost no experience, newly graduated medical students enter teaching hospitals around the country every July, beginning their careers as interns, while last year’s interns and junior residents take a step up and assume new responsibilities. Some experienced physicians share a joke about this changing of the guard: Don’t get sick in July.
Eye contact during early infancy may be a key to early identification of autism, according to a new study, which revealed the earliest sign of developing autism ever observed- a steady decline in attention to others’ eyes within the first two to six months of life.
Researcher Finds Way to Reduce Unnecessary Lab Tests, Decrease Patient Costs by Modifying Software DesignNovember 5, 2013 12:36 pm | News | Comments
When patients undergo diagnostic lab tests as part of the inpatient admission process, they may wonder why or how physicians choose particular tests. Now, a researcher and her colleagues have studied how to modify these lists to ensure health professionals order relevant tests and omit unnecessary lab tests.
Researchers have found a more accurate method to screen for bacterial meningococcal infection in its early stages, when it's hardest to detect.
A new study questions previous suggestions that attention deficit hyperactivity disorder (ADHD) is the result of fundamental abnormalities in dopamine transmission, and suggests that the main cause of the disorder may lie instead in structural differences in the grey matter in the brain.
Borrowing a tactic used to identify lung infections, researchers have discovered a potential method to identify traumatic brain injuries that uses positron emission tomography scans and the body’s immune response to a brain injury.
According to a new study, a novel mammography procedure could generate substantial added-value for the diagnosis of breast cancer in medical practice.
A new breast cancer risk gene has been discovered which explains the early-onset breast cancer in some multiple-case breast cancer families.
In a small preliminary study, researchers say a blood test based on detection of epigenetic alterations may reveal the earliest signs of pancreatic cancer, a disease that is nearly always fatal because of its late diagnosis.
New research indicates that brain scans show signs of autism that could eventually support behavior-based diagnosis of autism and effective early intervention therapies.
