For efficiency, the human brain often takes snapshots. But with age, inflamed brain cells can lead to memory loss or dementia. Enter a US-based research team and its nasal spray which can stop or even reverse the process. Made using bio-molecules (microRNAs) developed from neural stem cells, it is delivered via the nose into the wall of the hippocampus....

Saliva provides information about possible heart failure. Alzheimer’s, meanwhile, is often diagnosed through an analysis of the cerebrospinal fluid after changes in cognitive capabilities. But loss of smell can be an initial warning sign. Enter an American research team and its new nasal swab aimed at early detection. In a 22-person study, different immune and nerve cells were removed...

Music-lovers can create tracks with increasing ease. Now, a study at Northeastern University has shown that music can stimulate the brain’s nerve pathways, having a positive impact on cognitive illnesses and dementia. This is particularly true for music we choose ourselves, and which we listened to as teenagers. In a recent test, cognitively healthy older adults were asked to...

Cancer residue caused by treatment could be removed. Alzheimer’s disease, accounting for 60-70% of dementia cases, is caused by degenerative nerve cells in the brain. The body’s energy to remove them comes from mitochondria. If these become damaged, however, the whole cell dies. Making the clean-up process increasingly problematic as we age. Now, an international research team spearheaded by...
