A majority of Parkinson’s patients report a diminished sense of smell, which starts to occur a number of years before the onset of other symptoms. Researchers are exploring whether scent-processing neurons which connect the nose to the brain may play a…
A new study reveals the mechanisms by which neurons and astrocytes work together to form synapses.
Bach1, a protein that blocks the expression of genes associated with neuroprotection, has been implicated in Parkison’s disease. Researchers say blocking Bach1 slows the deterioration of brain cells in preclinical models of Parkinson’s disease.
Reducing tau can prevent abnormal brain activity associated with Alzheimer’s disease, autism, and epilepsy.
While the positive impact of breastfeeding on babies is well known, little is known about the positive benefits for the mother. A new study reveals women who breastfed their children performed better on cognitive tests at age 50 than those who fed thei…
While a low-protein diet can accelerate neurodegeneration, consuming Amino LP7, a combination of essential amino acids, could slow the progression or inhibit the development of dementia.
Cold exposure therapies could help alleviate symptoms of multiple sclerosis by depriving the immune system of its energy.
Mirtazapine, an antidepressant commonly prescribed to treat dementia-associated agitation, is no more effective than a placebo and may increase mortality risks, researchers report.
A new study reveals how adipocytes, or fat cells, play a role in cognitive decline and increased neurodegeneration risks. Using genetically modified mouse models, researchers found oxidative stress through exposure to a Western diet increased the produ…
Glial cells coordinate immune responses in the gut following infection. Researchers report glial cells could be targets for therapeutics to treat inflammatory bowel disorders.
When dysfunctional, somatostatin interneurons drive brain activity and provoke seizures.
Too much or too little sleep were both linked to increased risk of cognitive decline, researchers report.
Fenofibrate, an FDA-approved drug commonly used to treat high cholesterol, activated support cells around sensory neurons in mouse models of spinal cord injury, helping them regrow twice as fast as a placebo.
Some viral infections could increase intercellular spreading of protein aggregates associated with neurodegenerative disorders, increasing the risk for developing Alzheimer’s, Parkinson’s, and other neurodegenerative diseases.
A new rodent study uncovers a neural circuit in the brain that appears to govern pain-induced anhedonia. Altering the activity of this circuit restored motivation in pre-clinical models of pain.
Variations in the TSPO neuroinflammation-associated protein’s structure correlates with worse survival outcomes for male glioblastoma brain cancer patients than females.
Study reveals a causal mechanism for pain reduction may be due to an antibiotic-induced shift in the gut’s amino acid concentrations.
Study reveals microglia play an important role in the maintenance of blood delivery to the brain. The findings may prove important to the study and treatment of cognitive decline, dementia, and stroke.
Each person has a specific brain “fingerprint”, and that fingerprint changes over the course of our lives, a new study reports.
Those with a genetic predisposition to clinical depression are more likely to exhibit physical symptoms including migraines, chronic pain, and fatigue, researchers report.
