Depression and Anxiety Linked to Accelerated Biological Aging in Adults

Adults with advanced biological age are at a higher risk of depression and anxiety, according to a study that found participants with older biological age were 6% more likely to develop these mental health conditions at the 8.7-year follow-up compared to those who tested younger biologically.

Prioritizing Brain Health: Blood Pressure Control Reduces Alzheimer’s Risk and Minimizes Brain Aging

A recent study suggests that intensive blood pressure treatment with a target of less than 120 mm Hg can reduce the risk of adverse cerebrovascular events and improve overall brain health in adults over 50. Patients who more intensely managed their hypertension had fewer white matter lesions in the brain. White matter lesions are associated with an increased risk of Alzheimer's disease, cognitive decline, and accelerated brain aging.

Stress Rapidly Increases Biological Age, but Recovery Turns Back the Clock

Stress can cause rapid and transient increases in biological age, which can be reversed upon recovery, according to a new study. Using DNA methylation clocks, researchers found that stress triggers short-term fluctuations in biological age in humans and mice. The findings challenge the idea that biological age has a unidirectional upward trajectory over the life course, and highlights the importance of reducing biological age to improve longevity.

Brain Drain: Common Infections Tied to Cognitive Decline

CCommon infections, including the chickenpox virus and herpes simplex virus type 1, can worsen cognitive performance and increase the risk of developing Alzheimer's disease in middle-aged and older adults, a new study reports. The findings add to the growing body of evidence linking common infections to poor brain health associated with aging.

Strong Sense of Purpose in Life Promotes Cognitive Resilience Among Middle-Aged Adults

A stronger sense of purpose enhances cognitive resilience in middle-aged adults, a new study reports. Those who report greater purpose in life have greater functional connectivity between the default mode network and other brain areas, which represents a neuroprotective mechanism that could improve cognitive function in old age.

How Diet Can Impact the Brain

Scientists have called for a consensus on which cognitive tests to use when assessing the impact of nutrition on brain function They recommend reducing the number of tests and standardizing reporting guidelines, which could enable researchers to pool data and make more confident decisions about how diet affects cognition over the life course.

High Blood Pressure in Your 30s Is Associated With Worse Brain Health in Your 70s

High blood pressure during your 30s increases the risk of dementia and cognitive decline later in life. Treating hypertension early can help to prevent dementia and Alzheimer's disease in your 70s.

The Cold Truth: Frequent Common Colds Linked to Alzheimer’s Risk

Suffering from frequent colds and flu may impact brain aging, accelerate cognitive decline, and could increase the risk of developing Alzheimer's disease. In mice, intermittent experiences of moderate inflammation, such as that caused by the flu or common cold, caused impaired cognition and disrupted neural communication.
