Emerging evidence suggests that poor oral health is associated with Alzheimer’s disease (AD), but there is a lack of large-scale clinical studies demonstrating this link. The increased risk of dementia is potentially due to the spread of bacteria and inflammatory molecules from the mouth to the brain.

A review paper published Thursday in the journal Genomic Psychiatry suggests… Continue reading →
Modifiable risk factors for dementia include smoking, lack of exercise, hearing loss, obesity, and high blood pressure, among others listed by the Lancet Commission on Dementia Prevention, Intervention, and Care. One of the more recent additions to their list is visual impairment, which one study (Varadaraj et al., 2021) concluded as having possibly led to… Continue reading →
Many older adults take numerous medications. This practice, called polypharmacy, has been linked to lower memory function.

Some affect short-term memory, which refers to anything that happened within the last 30 seconds. Examples of this are forgetting what you… Continue reading →
In recent research, the emphasis on sleep duration as a key factor for health has shifted towards the consistency of sleep schedules. A groundbreaking study involving over 60,000 participants from the UK Biobank has revealed that sleep regularity is a more significant predictor of mortality risk than sleep duration. This study, which utilized more than… Continue reading →
Everyone has experienced the power of aromas to evoke recollections of past experiences. You may walk into a room and smell something cooking, or the scent of a perfume or cologne a loved one wore years ago, and memories just suddenly surface. This happens because the olfactory system is the only sensory system that has… Continue reading →
