Short-term reactivation of brain between encoding of memories enhances recall, study finds

Past neuroscience and psychology studies have shown that after the human brain encodes specific events or information, it can periodically reactivate them to facilitate their retention, via a process known as memory consolidation. The reactivation of memories has been specifically studied in the context of sleep or rest, with findings suggesting that during periods of inactivity, the brain reactivates specific memories, allowing people to remember them in the long term.

AFib diagnosed in midlife linked to 21% increased risk of dementia at any age, 36% higher risk of early-onset dementia

New research presented at the EHRA 2025, a scientific congress of the European Society of Cardiology, shows that the presence of atrial fibrillation (AFib) increases the risk of future dementia by 21% in patients diagnosed with AFib under 70 and the risk of early-onset dementia (diagnosed before age 65 years) by 36%.
