Treating dementia with stem cells

Scientists invented an injection of cells to repair the damage parts of the brain & restore lost memory. This invention is a step closer towards treating Alzheimer disease with stem cells. It is the first time that neural stem cells have been used to restore memory in late stage Alzheimer's disease. They took the trial on mice & results were very much positive.

They believe the same technique might one day work on humans. Some scientists believe it could one day be treated with transplants of stem cells. That the master cells that can turn into different types of tissue. They injected mouse stem cells into the brains of mice genetically engineered to have Alzheimer's disease. After a month, the animals did far better in memory tests than Alzheimer's mice that were not treated.

The researchers found that stem cells restored memory by secreting a protein called brain-derived neurotrophic factor, or BDNF, which strengthens connections between neurons - the brain cells that process and transmit messages. Stem cells or a product from them, such as BDNF, will be a useful treatment for Alzheimer's.

The neural stem cells were helping the brain form new synapses & nursing the injured neurons back to health. It is interesting & novel studies which will help researchers develop a better understanding of how stem cell therapy might help in the fight against dementia. It suggests this type of research may produce effective treatments in the future but it is still very early days & much more research is needed
