“FTA: > Using a songbird as a model, scientists have described a brain pathway that replaces cells that have been lost naturally and not because of injury. If scientists can further tap into the process, it might lead to ways to encourage replacement of cells in human brains that have lost neurons naturally because of aging or Alzheimer's disease.”

“>Then he linked the neurons found in the brain to the rest-activity behavior data collected in that person's final year of life. He found that the fewer neurons one had, the more sleep fragmentation that person experienced in the last year of life.”

“The authors of the study screened 2,000 bioactive compounds to gauge their ability to protect rodent and human neurons from apoptosis and identified five compounds, including 7,8-dihydroxyflavone, that showed potential in protecting the cells.”

“But exercise also helps manage its symptoms once the disease develops. Exercise activates pathways that are involved in maintaining connections between neurons, making them stronger and repairing damage.”

“The researchers also observed a drop in the resting brain connections among neurons managing actions, beginning around middle age. This drop in connections became even more pronounced when the mice were doing tasks, suggesting that the brain's ability to retain thoughts might weaken with age.”

“Blood-brain barrier - Another membranous barrier in the body that loses its integrity with age. Increased microbial toxins in the blood because of increased intestinal permeability may stress the blood-brain barrier, injuring neurons and promoting disease.”

“The authors examined the brains of 45 study subjects (median age at death, 89.2), identifying ventrolateral preoptic neurons by staining the brains for the neurotransmitter galanin.”

“Poor cerebral blood flow is commonly observed in mice and humans and may contribute to impaired amyloid-beta clearance, thereby accelerating the progression of Alzheimer's disease. In addition, heat exposure increases the production of BDNF to promote neurogenesis – the growth of new neurons in the brain (as described above).”

“When they boosted the activity of an enzyme called glycogen phosphorylase, which breaks down glycogen, symptoms of tauopathy improved dramatically: The fruit flies showed fewer signs of neurodegeneration, and human neurons became healthier.”

“Skin cells that are reprogrammed into neurons that produce dopamine will be transplanted into the brains of people with Parkinson’s disease in a new trial in Japan. People with Parkinson's lose dopamine-producing neurons which are involved in motor skills. Last year this technique was shown to improve disease severity in monkeys with a disease that is similar to Parkinson's disease.”
