Your brain resets at ages 9, 32, 66 and 83: Study maps life's neural shifts
A new Nature Communications study finds brain ageing isn't linear, with key network 'turning points' at 9, 32, 66 and 83 that mark distinct phases from childhood to late life

How heavy metals in polluted air trigger fatigue, headaches and brain fog
Beyond PM2.5 and PM10, polluted air carries neurotoxic metals like lead, arsenic and cadmium that inflame the brain, disrupt energy pathways and trigger fatigue and fogginess on high-AQI days

Scientists find special cells in brain that can stop Alzheimer's: Study
In a study published in Nature, the team found that microglia with lower levels of a transcription factor called PU.1 and higher expression of a receptor known as CD28 help reduce brain inflammation

Boosting anti-viral immune response could slow down aging, says study
Scientists have uncovered details regarding an immune response to a virus present in all human tissues, that kicks in in the elderly and eliminates senescent, or aging, cells in the skin. Senescent cells are those that stop dividing but do not die, accumulating in the body over time, fuelling chronic inflammation and contributing to conditions such as cancer and degenerative disorders. Eliminating senescent cells from aging tissues has been found to restore tissue balance in mice, leading to an increased healthy lifespan. When a team of scientists, led by Massachusetts General Hospital (MGH), US, found that the number of senescent cells in samples from old individuals did not increase as the individuals got older, they realised that there is some mechanism kicking in to keep the aging in check. The scientists have described their findings in the journal Cell. Experiments have proved that in the elderly, certain immune cells called killer CD4+ T cells keep senescent cells from ...

Degeneration of neurons makes Alzheimer's patients drowsy: Study
According to a recent study, the drowsiness that many Alzheimer's patients experience are caused not by a lack of sleep, but rather by the degeneration of a type of neuron that keeps us awake
