In patients with mild cognitive impairment, apathy can be a predictor of Alzheimer’s disease
The presence of apathy in patients with mild cognitive impairment is strongly linked to a progression to Alzheimer’s disease, giving physicians a possible early diagnosis tool, according to UTHealth Houston research published recently in the Journal of Alzheimer’s Disease.

Do Sleep Medications Increase Your Chances of Dementia?
A new study shows that sleep medications increase the risk of dementia in whites. But the type and quantity of the medication may be factors in explaining the higher risk. It follows previous work that shows Blacks have a higher likelihood than whites of developing Alzheimer’s, the most common type of dementia, and that they have different risk factors and disease manifestation.

Study finds obesity-related neurodegeneration mimics Alzheimer’s disease
A new study led by scientists at The Neuro (Montreal Neurological Institute-Hospital) of McGill University finds a correlation between neurodegeneration in obese people and Alzheimer’s disease (AD) patients. Previous research has shown that obesity is linked with Alzheimer’s disease (AD)-related changes, such as cerebrovascular damage and amyloid-β accumulation. However, to date no research has made a direct comparison between brain atrophy patterns in AD and obesity.

Exposure to World Trade Center Dust Exacerbates Cognitive Impairment in an Animal Model of Alzheimer’s
Mice exposed to World Trade Center dust exhibit a significant impairment in spatial recognition and short- and long-term memory, as well as changes in genes related to immune-inflammatory responses and blood-brain barrier disruption, according to a study conducted by researchers from the Icahn School of Medicine at Mount Sinai and published January 17 in the Journal of Alzheimer’s Disease.

Smoking increases chances of mid-life memory loss, confusion
Middle-aged smokers are far more likely to report having memory loss and confusion than nonsmokers, and the likelihood of cognitive decline is lower for those who have quit, even recently, a new study has found. The research from The Ohio State University is the first to examine the relationship between smoking and cognitive decline using a one-question self-assessment asking people if they’ve experienced worsening or more frequent memory loss and/or confusion.

Why a healthy lifestyle is not enough to prevent dementia
Dementia is on the rise in Germany. In the absence of treatment options, the focus is shifting to preventing dementia. In particular, a healthy lifestyle is considered beneficial for brain health. A study by the Faculty of Medicine now shows that opportunities for a healthy lifestyle are unequally distributed: being socially disadvantaged is associated with a higher risk of dementia. The current findings have been published in the Journal of Alzheimer’s Disease.

Dementia Was Associated with COVID-19 Mortality, but the Association Was Weaker Than in Previously Published Studies
Since December 2019, more than 60 million people have been diagnosed with coronavirus disease 2019 (COVID-19) worldwide, while approximately six million individuals have died as a result of the disease. Hospital treatment was required in about 10%–20% of COVID-19 patients, with this proportion decreasing over time. Several studies have shown the impact of dementia on mortality in COVID-19 patients, however, most studies were conducted during the first months of the COVID-19 pandemic.

PNI Study Links Muscular Strength and Mobility to Brain Health
Results from a clinical research study co-authored by physicians and scientists at the Pacific Neuroscience Institute (PNI) at Providence Saint John’s Health Center indicate a correlation between two modifiable risk factors – muscular strength and mobility – and brain atrophy among persons with Alzheimer’s disease.

Previous brain injury may be associated with higher risk of FTD
A recent study from the University of Eastern Finland shows that previous traumatic brain injury may potentially affect the risk of frontotemporal dementia (FTD), especially in patients who did not carry a causal genetic mutation. In addition, patients who had suffered a head injury appeared, on average, to develop FTD earlier than others. The researchers compared Finnish FTD patients with patients with Alzheimer’s disease, and with healthy controls.

Controversial Alzheimer’s Drug Approval Sparks Surprising Impact
When the U.S. Food and Drug Administration gave controversial accelerated approval to the first Alzheimer’s drug in nearly 20 years, it had a surprising impact on attitudes about research into the disease. A survey by University of California, Irvine neuroscientists has found news coverage of the FDA’s decision made the public less willing to volunteer for Alzheimer’s pharmaceutical trials. The study was conducted by the UCI Institute for Memory Impairments and Neurological Disorders, known as UCI MIND.
