Lab mouse
Molecular Psychiatry has recently published a report from the University of Cambridge detailing how the brain’s extracellular matrix (ECM) changes with age, negatively impacting memory, and how modifying the components of the brain ECM can revitalize memory in mice [1]. What is neuroplasticity? Neuroplasticity is the ability of neurons to form new connections. This ability...
Rat in maze
Researchers from Hebei Medical University in China have found that testosterone supplementation ameliorates age-related brain dysfunction in male rats. A focus on mitochondria Why we Age: Mitochondrial DysfunctionAs they age, the mitochondria in our cells lose their ability to provide cellular energy and release reactive oxygen species that harm cells and cause increasing levels of...
Blood cells in an artery
A mouse study published in Aging Cell has outlined the similarities between artificially restricted cerebral blood flow and the reduced blood flow associated with aging. Aiming to understand vascular dementia Prior research has shown that reduced cerebral blood flow, known as hypoperfusion, results in vascular dementia and brain atrophy through multiple mechanisms, including neuroinflammation and...
Elderly woman sleeping
Quality sleep is one of the foundations of health, and a new study suggests that poor sleep quality is a major risk factor for developing Alzheimer’s disease and other dementias. Dementia is a rising global problem Worldwide, close to fifty million people currently live with Alzheimer's disease or other forms of dementia. According to the...
Blood-brain barrier
Research suggests that the degradation of the blood-brain barrier over time is a factor in the development of brain diseases. An organ we don't want to age As our brains age, we experience memory loss, a decreased ability to multitask, a lower attention span, and slower information processing [1, 2]. Severe diseases can occur as...
Qigong practice
Researchers from the University of Hong Kong have found that qigong, an ancient Chinese mind-body practice, improves cognitive abilities, lowers inflammation, and increases the size of the hippocampus in elderly subjects [1]. A value to tradition Scientists agree that if we want to live longer, exercise is still one of our best options. It has...
