Abnormal hyperactivation in the brain may be an early sign of Alzheimer's

Fri, 01/22/2021 - 02:08
A psychology and neuroscience professor has just targeted an early biomarker of the disease.

'Aging well' greatly affected by hopes and fears for later life

Fri, 01/22/2021 - 01:39
If you believe you are capable of becoming the healthy, engaged person you want to be in old age, you are much more likely to experience that outcome, a recent study shows.

Age provides a buffer to pandemic's mental health impact, researchers say

Thu, 01/21/2021 - 23:50
Older adults are managing the stress of the coronavirus pandemic better than younger adults, reporting less depression and anxiety despite also experiencing greater general concern about COVID-19, according to a recent study.

See how they run: 'Exercise protein' doubles running capacity, restores function and extends healthy lifespans in older mice

Thu, 01/21/2021 - 23:49
A new study shows that humans express a powerful hormone during exercise and that treating mice with the hormone improves physical performance, capacity and fitness. Researchers say the findings present new possibilities for addressing age-related physical decline.

Strange colon discovery explains racial disparities in colorectal cancer

Thu, 01/21/2021 - 23:46
The colons of African-Americans and people of European descent age differently, new research reveals, helping explain racial disparities in colorectal cancer.

'Attitude of gratitude' keeps older people in Japan feeling hopeful as they age

Thu, 01/21/2021 - 23:46
Older people in Japan have an 'attitude of gratitude' which keeps them feeling hopeful despite the challenges of aging, a new study says.

Immune driver of brain aging identified

Wed, 01/20/2021 - 22:18
Stanford scientists have identified a key factor in mental aging and shown that it might be prevented or reversed by fixing a glitch in the immune system's frontline soldiers.

NAD+ can restore age-related muscle deterioration, research finds

Tue, 01/19/2021 - 22:14
Scientists have discovered that Alzheimer's-like protein aggregates underly the muscle deterioration seen in aging. But the aggregates can be reversed by boosting the levels of nicotinamide adenine dinucleotide (NAD+), which turns on the defense systems of mitochondria in cells and restores muscle function.

Eye tests predict Parkinson's-linked cognitive decline 18 months ahead

Tue, 01/19/2021 - 20:58
Simple vision tests can predict which people with Parkinson's disease will develop cognitive impairment and possible dementia 18 months later, according to a new study. In a related study, the researchers also found that structural and functional connections of brain regions become decoupled throughout the entire brain in people with Parkinson's disease, particularly among people with vision problems.

Increased risk of Parkinson's disease in patients with schizophrenia

Fri, 01/15/2021 - 21:33
A new study shows that patients with a schizophrenia spectrum disorder have an increased risk of Parkinson's disease later in life. The increased risk may be due to alterations in the brain's dopamine system caused by dopamine receptor antagonists or neurobiological effects of schizophrenia.

Even skin shielded from the sun accumulates genomic DNA changes from UV light

Fri, 01/15/2021 - 03:09
For the first time, scientists have measured the different types of genomic DNA changes that occur in skin cells, finding that mutations from ultraviolet (UV) light is especially common, but Black individuals have lower levels of UV damage compared to white people.

Physical frailty syndrome: A cacophony of multisystem dysfunction

Thu, 01/14/2021 - 23:31
Aging experts synthesize converging evidence that the aging-related pathophysiology underpinning the clinical presentation of phenotypic frailty is a state of lower functioning due to severe dysregulation of the complex dynamics in our bodies that maintains health and resilience. When severity passes a threshold, the clinical syndrome and its phenotype are diagnosable. This paper summarizes evidence meeting criteria for physical frailty as a product of complex system dysregulation distinct from the cumulative-deficit-based frailty index of multimorbiditys.

Memory may be preserved in condition with brain changes similar to Alzheimer's disease

Thu, 01/14/2021 - 02:42
Primary progressive aphasia is a rare neurodegenerative condition characterized by prominent language problems that worsen over time. About 40% of people with the condition have underlying Alzheimer's disease. But a new study has found that people with the condition may not develop the memory problems associated with Alzheimer's disease.

MIND and Mediterranean diets associated with later onset of Parkinson's disease

Thu, 01/14/2021 - 01:15
A new study suggests a strong correlation between following the MIND and Mediterranean diets and later onset of Parkinson's disease (PD). While researchers have long known of neuroprotective effects of the MIND diet for diseases like Alzheimer's and dementia, this study is the first to suggest a link between this diet and brain health for Parkinson's disease (PD).

Approximately half of AD dementia cases are mild, one-fifth are severe

Wed, 01/13/2021 - 22:37
What percent of patients with Alzheimer's Disease (AD) currently have severe dementia? Do more people have mild disease? Or are the majority suffering with moderate dementia? A new study using data from the Framingham Heart Study (FHS) sheds light on these trends.

New studies support blood test for early detection of Alzheimer's disease

Wed, 01/13/2021 - 20:38
Researchers provide convincing evidence that an in-house developed blood test for Alzheimer's disease can detect the disease early and track its course, which has major implications for a potential use in clinical practice and treatment trials.

Rotten egg gas could guard against Alzheimer's disease

Tue, 01/12/2021 - 21:31
Typically characterized as poisonous, corrosive and smelling of rotten eggs, hydrogen sulfide's reputation may soon get a face-lift thanks to researchers. In experiments in mice, researchers have shown the foul-smelling gas may help protect aging brain cells against Alzheimer's disease.

Study links severe COVID-19 disease to short telomeres

Mon, 01/11/2021 - 22:27
Patients with severe COVID-19 disease have significantly shorter telomeres, according to a new study. Researchers postulate that telomere shortening as a consequence of the viral infection impedes tissue regeneration and that this is why a significant number of patients suffer prolonged sequelae.

Including unhealthy foods may diminish positive effects of an otherwise healthy diet

Sun, 01/10/2021 - 01:54
Researchers have reported diminished benefits of a Mediterranean diet among those with high frequency of eating unhealthy foods.

Journal article reviews century of data showing COVID-19 likely to impact the brain

Thu, 01/07/2021 - 03:43
Decades of data paint a compelling case for why COVID-19 survivors, even those with few symptoms, could experience long-term effects on the brain and central nervous system.
