Get a whiff of this: Smell test could sniff out serious health problems

... of Cincinnati researchers may sniff out olfactory disorders that could be an early warning of Alzheimer’s disease, Parkinson’s disease and other problems outside the typical sensory loss associated with aging. The Sniff Magnitude Test (SMT), an invention of UC Psychology Professor Robert Frank and Professor E...

Rare cell prevents rampant brain activity

... the mechanism is essential to understanding brain disorders like epilepsy. "A characteristic feature of epilepsy is the hyperactivation of cortical pyramid cells, which is exactly what this mechanism inhibits. It is possible that epilepsy is related to a deficit of Martinotti cells or a deficiency of Marti...

MIT model helps researchers 'see' brain development

...cal indicator, for early diagnosis of neurological disorders such as autism. The researchers describe their model and analysis in the April issue of IEEE Transactions on Medical Imaging. Peng Yu, a graduate student in the Harvard-MIT Division of Health Sciences and Technology (HST), is first author on t...

Horse genome assembled

...nditions in horses that are genetically similar to disorders seen in humans, including musculoskeletal, neuromuscular, cardiovascular and respiratory diseases. The SNPs are available at the Broad Institute web site ( www.broad.mit.edu/mammals/horse/snp ) and will be available shortly from NCBI's Single Nucleot...

When your brain talks, your muscles don't always listen

... quality in older adults, as well as patients with disorders such as cerebral palsy or multiple sclerosis, or who are recovering from strokes. Every move you make is made possible through a miraculous communications network involving the brain at the command center, the spinal cord, billions upon billions o...

New recommendations against a major opportunistic infection -- cryptococcosis

... HIV, but who also suffer from other immunological disorders or who are receiving immunosuppressive treatments. Most often, the fungus causes meningoencephalitis, but the infection can also be localised in the lungs. The incidence of cryptococcosis in France has decreased by half with the availability of antir...

Anxiety disorders surprisingly common yet often untreated

...mptoms, especially pain, and their links to mental disorders including anxiety and depression. Dr. Kroenke a...GAD-7 flagged those patients with possible anxiety disorders for physician follow-up. These questions ask the patient if he or she has felt nervous or has been u...

Scientists clone mice from adult skin stem cells

...s, such as liver, pancreatic and neurodegenerative disorders where researchers are only able to obtain affected tissue from autopsies," says Fuchs. If on the other hand, scientists are able to generate embryonic stem cells from the skin of a patient, for example an Alzheimer's patient, these embryonic stem...

'Night owls' report more insomnia-related symptoms

...insomniacs.? Insomnia, a classification of sleep disorders defined by difficulty falling asleep or staying asleep, waking up too early, or poor quality sleep, is the most common sleep complaint at any age. About 30 percent of adults have symptoms of insomnia. The amount of sleep a person gets affects his...

Researchers discover gene crucial for nerve cell insulation

... The discovery has implications for understanding disorders of myelin production. These disorders can affect the peripheral nervous system—the nerves outside the brain and spine. These disorders ar...

Putting an old drug to a new use

... the consequence of one of the most common genetic disorders in Europe, hereditary hemochromatosis, which affects about one in 300 Europeans. Excess iron also accumulates after repeated blood transfusions and can cause organ failure over time. Günter Weiss, a clinician from the Innsbruck Medical University, an...

Using brain scans, researchers find evidence for a two-stage model of human perceptual learning

... These findings might be helpful in understanding disorders that involve differences in the interaction of bottom-up and top-down information in the brain, such as autism or schizophrenia, Riesenhuber said. It also suggests how the learning of visual skills can be enhanced by directly monitoring neuronal acti...

FSU researchers determine a critical factor in workings of proteins

...ould lead to more effective treatments for genetic disorders and other life-threatening conditions. Now, a pair of Florida State University researchers' new theory has been proven to accurately predict the association rate for proteins. Their theory is outlined in the February issue of the scientific journal ...

Racing neurons control whether we stop or go

... children with attention deficit and hyperactivity disorders than in other children," he said. The model has been widely accepted and has also been used to explain cognitive problems in people with obsessive-compulsive disorder, schizophrenia and Parkinson’s disease. "We think of people who are impulsive...

How genetic malfunction causes a form of retardation

...en in NS, or perhaps even in more commonly studied disorders such as Rett Syndrome, might first perturb cell genesis, and then this might in turn alter many later aspects of neural development, ultimately resulting in impaired circuitry and cognitive dysfunction.? ...

Long-term narcotics use for back pain may be ineffective and lead to abuse
