Researchers at the Beckman Institute for Advanced Science and Technology demonstrated that emotion enhances memory for contextual details, challenging the view that emotion impairs the ability to remember such information. The report was led by doctoral student Paul Bogdan, currently a postdoc…
Heavy Metal Cadmium May Be Tied to Memory Issues for Some
The heavy metal cadmium, which is found in the air, water, food and soil, is known to cause health problems. A new study published in the September 4, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology, examined if thinking and memory skills were associated with cadmium exposure. They found no association when they looked at the group as a whole.
Living with Grief
Grief forever changes us. The journey that we walk through changes who we are and how we perceive the world around us. Those who are unfamiliar or uncomfortable with grief may prompt us to move on. When they try this, we often plant our heels into the ground and resist. This may come as a surprise to them.

In a new study, a molecule identified and synthesized by UCLA Health researchers was shown to restore cognitive functions in mice with symptoms of Alzheimer’s disease by effectively jumpstarting the brain’s memory circuitry.
New research identifies biomarkers that link alcohol use disorder and Alzheimer disease
Researchers agree that alcohol use can produce global and regional tissue volume changes in the brain, and that excessive alcohol use is associated with dementia and cognitive decline. A new study has examined the relationship between Alzheimer disease – the most common type of dementia – and alcohol use disorder (AUD), discovering biomarkers that link the two.
People with Severe Alcohol Use Disorder May Form and Recall Social Memories Differently
People with severe alcohol use disorder tended to have greater difficulty forming new social memories. And, while they had better immediate recall of positive than negative social cues, for longer-term memories, they tended to remember more negative experiences than positive ones.
Alcohol-related blackouts during youth are markers of future neurocognitive risk
Alcohol-related blackouts (ARBs) are fairly common among younger, social drinkers – even considered a rite of passage by some. Yet new research has found that blacking out predicts unique, underlying brain changes involved with learning, memory, and the processing of visual information.

Addressing disparities in Alzheimer’s disease research
Age-related cognitive decline and the escalating prevalence of Alzheimer’s disease are pressing social challenges as the population of those 65 and older continues to expand. Age is the primary risk factor, but research has shown that social and structural determinants of health play significant roles in the higher incidence of Alzheimer’s among marginalized communities.
Fluctuating Levels of Cholesterol and Triglycerides Linked to Increased Risk of Dementia
Older people who have fluctuating levels of cholesterol and triglycerides may have a higher risk of Alzheimer’s disease and related dementias compared to people who have steady levels, according to new research published in the July 5, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. While the study found a link, it does not prove that fluctuating levels of cholesterol and triglycerides cause dementia.

A new study provides novel insight into the benefits of exercise, which should motivate adults to keep moving throughout their lifetime, especially during middle age. Long-term exercise profoundly benefits the aging brain and may prevent aging-related memory function decline by increasing the survival and modifying the network of the adult-born neurons born during early adulthood, and thereby facilitating their participation in cognitive processes.

Events Serve as “Stepping Stones” en Route to Retrieved Memories
Lost your keys again? One way to retrace your steps involves scanning your memory to find them, such as reaching back to the last moment you clearly remember having them—say, as you walked in the door—before skipping ahead to a “phone call” event and then a “watching TV” event, at which point you might recall placing the keys next to the remote.
