“Findings from a 2017 study suggest that plasma levels of BDNF are a marker for suicidality. BDNF is a protein that plays critical roles in the creation and functioning of neurons and the ability of synapses to strengthen or weaken over time.”

“BDNF is a protein that acts on neurons in the central and peripheral nervous systems. A single-nucleotide polymorphism (SNP) in the gene that encodes BDNF causes a substitution of the amino acid valine (Val) by methionine (Met) in the BDNF protein.”

“Tau is a protein that clumps together and forms tangles inside neurons in the brains of people with Alzheimer's disease. When tau tangles form, the system for transporting mitochondria, lipids, and cellular metabolites is disrupted.”

“People who are infected with a virus commonly report having aches and pains. Most people who are infected with SARS-CoV-2, the virus that causes COVID-19, exhibit symptoms such as fever, cough, and difficulty breathing, but not pain.”

“A recent study in mice found that C. albicans triggers a dual-pronged defense system involving both the brain and the immune system; however, when elements of this system fail, the fungi can impair the blood-brain barrier and drive amyloid plaque formation.”

“The brain loses about 5 percent of its volume every decade after the age of 40 years, likely due to the death of neurons in the gray matter. These losses contribute to age-related cognitive decline and loss of neuroplasticity, the brain's ability to change and adapt to new exposures.”

“However, if high AGE levels accumulate in the tissues and blood, they can become pathogenic, driving many chronic diseases, including diabetes, atherosclerosis, Alzheimer's disease, macular degeneration, and kidney failure.”

“These effects have been attributed to less reactive oxygen species production, greater immune system clearance of amyloid beta proteins, and an increase in glial cell line-derived neurotrophic factor or GDNF—a brain protein that helps neurons survive and regenerate.”

“The patients provided blood samples for genetic analysis and completed self-assessment questionnaires about depression, hopelessness, impulsivity, and the severity of their alcohol use. The authors followed up with participants for approximately one year to assess whether they had relapsed.”

“Findings from a new study suggest that N-acetylglucosamine, a sugar present in breast milk and widely available as a dietary supplement, promotes remyelination in people who have multiple sclerosis.”
