Alzheimer's & Dementia

Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills. Alzheimer’s is the most common cause of dementia among older adults. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities to such an extent that it interferes with a person’s daily life and activities.

Alzheimer’s Disease | Definition, Causes, Diagnosis & Treatment

Alzheimer’s Disease (AD) is the most common form of dementia worldwide (60-70% of all dementia cases) and is a progressive neurodegenerative disorder.

Study uncovers alcohol's damaging effects on brain cells through oxidative stress

Alcohol exposure leads to accumulation of oxidatively damaged proteins in neuronal cells. Differentiated cells are more susceptible to alcohol-induced oxidative protein damage despite higher resistance to cytotoxicity.

Superagers' brains resist age-related decline, study finds

Researchers explored brain white matter integrity in superagers, older adults with exceptional cognitive abilities, finding that while overall white matter health showed no significant differences, superagers displayed superior microstructure in frontal regions, potentially explaining their resistance to cognitive decline.

Youth-onset diabetes linked to higher Alzheimer's risk

Young people with diabetes may have a significantly higher risk of developing Alzheimer's disease later in life, according to a new study by researchers in the Lifecourse Epidemiology of Adiposity and Diabetes (LEAD) Center at the University of Colorado Anschutz Medical Campus.

Higher cardiorespiratory fitness levels linked to dramatically lower mortality and disease risks, study finds

A study in the British Journal of Sports Medicine, aggregating over 20.9 million observations, shows cardiorespiratory fitness (CRF) as a consistent predictor of reduced morbidity and mortality across various health outcomes in adults.

APOE4 gene linked to early onset Alzheimer's, target for therapeutic intervention

A study published in Nature Medicine delineates how APOE4 homozygosity distinctly accelerates Alzheimer's disease pathology and biomarkers from the age of 55, suggesting a unique form of the disease and a potential focus for targeted therapies.

Olive oil – 7 grams per day may keep the dementia away!

A large-scale study published in JAMA Network Open shows that daily consumption of seven or more grams of olive oil can reduce dementia-related mortality by 28% among American adults, underscoring the role of dietary habits in managing age-related cognitive decline.

Study identifies APOE4 homozygotes as high-risk group for Alzheimer's disease

Researchers from the Research Area on Neurological Diseases, Neuroscience, and Mental Health at the Sant Pau Research Institute, led by Dr. Juan Fortea, Director of the Memory Unit of the Neurology Service at the same hospital, have found that over 95% of individuals over 65 years old who have two copies of the APOE4 gene -APOE4 homozygotes- show biological characteristics of Alzheimer's pathology in the brain or biomarkers of this disease in cerebrospinal fluid and PET scans.

Global research offers insights about health burden disparities between genders

Globally, there are substantial differences between females and males (aged 10 and older) when it comes to health, with limited progress in bridging these health gaps over the past 30 years, according to a new study examining the disparities in the 20 leading causes of disease burden between females and males, across ages and regions, published in The Lancet Public Health journal.
