Boosting omega-3 fatty acid intake helps to preserve brain health and improve cognition in middle age, a new study reports. For those with the Alzheimer's associated APOE4 gene, omega-3 fatty acid intake was associated with greater hippocampal volume and less small vessel disease.
Brain cells exposed to blood taken from COVID-19 patients with delirium showed a decrease in neurogenesis and an increase in cell death. The findings also indicate a key role for cytokines produced in the immune system during infection and shed light on the molecular mechanisms of COVID-19 related delirium.
Researchers discovered personal odors can alter in people with Parkinson's disease. Based on this, they identified specific markers for Parkinson's in sebum, an oily substance secreted from the skin. They developed a new, non-invasive swab test that can identify Parkinson's with 95% accuracy.
Higher levels of the inflammatory C-reactive protein were discovered in older breast cancer survivors who experienced cognitive issues. The study is one of the first long-term assessments linking chronic inflammation to cognitive decline in breast cancer survivors.
SARS_CoV_2, the virus responsible for COVID-19 infects and replicates in astrocytes, reducing neural viability.
Researchers document traumatic brain injury as a global health problem that affects 55 million people worldwide and is the leading cause of injury-related death and disability.
Oxytocin, a hormone connected with bonding and love, could help to heal damage following a heart attack. Researchers found oxytocin stimulates stem cells from the heart's outer layer and migrates into the middle layer where it develops into muscle cells that generate heart contractions. This could be used to promote the regeneration of heart cells following a heart attack.
Diets high in guar gum, a dietary fiber and common food additive extracted from guar beans, limit inflammation and delay the onset of multiple sclerosis in mouse models.
Two short cycles of a low-calorie diet that mimics fasting reduced inflammation and delayed cognitive decline in mouse models of Alzheimer's disease. Researchers report the diet is safe for humans and could help reduce signs of Alzheimer's.
