Stress Affects People with Schizophrenia Differently
A new study reveals people with schizophrenia have a disrupted stress response. Researchers report those with schizophrenia have an increase in dopamine release in the striatum, but not in the prefrontal cortex, in response to stress.... Read More...
Pathway for Alzheimer’s Degeneration Discovered
Researchers have developed a new neuroimaging method to track neurodegeneration in Alzheimer's disease. The method helped uncover a new pathway for how degeneration spreads from one brain region to another.... Read More...
Neural Implants Modulate Microstructures in the Brain with Pinpoint Accuracy
Researchers have developed new neural implants that enable targeted delivery of drugs deep into brain structures.... Read More...
People with Family History of Alcoholism Release More Dopamine in Expectation of Alcohol
A new study reports people who have a family history of alcohol use disorder release more dopamine in the ventral striatum as a response to the expectation of receiving an alcoholic drink than those without a family history of alcoholism.... Read More...
Vascular Risk Interacts with Amyloid Levels to Increase Age Related Cognitive Decline
Vascular risk factors appear to have a negative synergistic effect with amyloid beta levels in the brain, researchers report. The study suggests a combination of increased vascular risk and higher amyloid levels in the brain can predict more rapid cognitive decline during aging.... Read More...
Neuroinflammation Seen in Spinal Cord and Nerve Roots of Patients With Chronic Sciatica
A new study reveals a link between chronic sciatica and inflammation in key areas of the nervous system. Researchers say the location of the inflammation could help to determine which patients will feel relief from steroid injections to curb the pain.... Read More...
Lack of Sleep May Be Linked to Risk Factor for Alzheimer’s
A new study reveals sleep deprivation can lead to an immediate increase in amyloid beta. ... Read More...
New Blood Test Useful to Detect Those at Risk of Developing Alzheimer’s
Researchers have developed a new blood test capable of detecting biomarkers of Alzheimer's disease long before the first symptoms appear.... Read More...
Novel PET Imaging Agent Could Help Guide Therapy for Brain Diseases
Researchers have developed a new imaging agent, which uses PET scans to target receptors neurons implicated in memory and learning.... Read More...
Looking Deeper into Brain Function
Researchers propose a new approach to neuroimaging studies. They suggest, rather than beginning with predefined behavioral functions and trying to assign associated brain regions, new studies should focus on selecting brain areas first and screen for potential behavioral associations....
