Millions of people across the world suffer from Alzheimer’s disease, where sufferers experience memory impairment. Researchers from Tohoku University and the University of California, Irvine have recently identified dopamine dysfunction as a previously unrecognized mechanism underlying memory impairment. The discovery potentially opens the door to new therapeutic means that could reverse cognitive decline in Alzheimer’s patients across the globe.

- DGIST Prof. Lee Kwang and team propose new neural law of dopamine that differs from existing theory - Developed original technology that simultaneously monitors electrical and chemical brain signals, redefining the correlation between changes in dopamine signaling within physiological range and neural signal processing in the brain - Findings are published in Nature Neuroscience

As our brains develop, cells within it ‘eat’ neuronal elements to clear out debris, pathogens and help improve efficiency. A recent study showed that motor learning in mice helped enhance the engulfing of synapses by Bergmann glial cells. The discovery could have possible implications for explaining why synaptic shrinkage and loss occur in depression, schizophrenia, and Alzheimer’s disease.

Despite great investments, an effective drug-based treatment for Alzheimer’s disease, the most common form of dementia among the elderly, remains elusive. Scientists led by Duke-NUS Medical School, in collaboration with Monash University, have published an online atlas of gene expressions at single-cell level in Alzheimer’s disease brains, aiming to boost to efforts to identify gene targets for drug development.
