Study helps understand why some people have persistent smell loss after COVID-19 infection

The reason some people fail to recover their sense of smell after COVID-19 is linked to an ongoing immune assault on olfactory nerve cells and an associated decline in the number of those cells, a team of scientists led by Duke Health report.

Research links mutation that causes Huntington's disease to developmental deficits in the brain's oligodendrocyte cells

A research team led by the University of California, Irvine has linked the mutation that causes Huntington's disease to developmental deficits in the brain's oligodendrocyte cells that are caused by changes in metabolism.

Study explores cellular alterations in six distinct neurodegenerative diseases

A perplexing range of neurodegenerative diseases are known to attack distinct regions of the brain, causing severe cognitive and motor deficit.

Study provides insights into the coordinated dance of nerve and vascular cells

Nerve cells need a lot of energy and oxygen. They receive both through the blood. This is why nerve tissue is usually crisscrossed by a large number of blood vessels.

Probiotic bacterium prevents neurodegeneration in animal model of ALS

A probiotic bacterium called Lacticaseibacillus rhamnosus HA-114 prevents neurodegeneration in the C. elegans worm, an animal model used to study amyotrophic lateral sclerosis (ALS).

Newly discovered mechanism could explain memory impairment in epilepsy

People with chronic epilepsy often experience impaired memory. Researchers at the University of Bonn have now found a mechanism in mice that could explain these deficits.

Study uncovers genetic cause of a novel developmental epilepsy syndrome

Neurodevelopmental disorders (NDD) encompass highly prevalent conditions such as autism and epilepsy, with cognitive disabilities alone affecting 1-3% of the global population.

Study provides deeper insights into skeletal muscle aging

A new research paper was published on the cover of Aging (listed as "Aging (Albany NY)" by Medline/PubMed and "Aging-US" by Web of Science) Volume 14, Issue 23, entitled, "Single nuclei profiling identifies cell specific markers of skeletal muscle aging, frailty, and senescence."

New support for a serotonin deficit in depression

Since the 1960s, researchers have postulated that major depression stems from disruptions in the serotonin neurotransmitter system, but the evidence for that idea, though plentiful, was indirect.

Study provides new insights into the pathology of LATE

Limbic predominate age-related TDP-43 encephalopathy or LATE is a recently recognized form of dementia that affects memory, thinking and social skills. It mimics Alzheimer's disease or AD (and sometimes co-exists with it), but LATE is a different condition, with its own risks and causes.

New clue may explain why women are at greater risk for Alzheimer's disease

Scientists at Scripps Research and Massachusetts Institute of Technology (MIT) have found a clue to the molecular cause of Alzheimer's - a clue that may also explain why women are at greater risk for the disease.

Study lays the groundwork for developing new technologies to detect neurodegenerative diseases

Researchers from the Neurobiology of miRNA team coordinated by Davide De Pietri Tonelli at the Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology) has discovered the correlation between a class of small RNA molecules, piRNAs, and brain inflammation.

Study uncovers previously unknown genetic cause of late-onset cerebellar ataxia

A new study published on Dec. 14, 2022 in the New England Journal of Medicine reports the identification of a previously unknown genetic cause of a late-onset cerebellar ataxia, a discovery that will improve diagnosis and open new treatment avenues for this progressive condition.

Flexible assemblies of nerve cells appear to be key to successful episodic memory

For the first time, scientists have recorded human nerve cells firing together in flexible assemblies, a process that appears necessary to successfully encode long-term memories, a study led by UT Southwestern researchers reports.

CRISPR/Cas9-engineered avatar mouse model of rare disease paves the way for targeted therapy

An international research team led by Dr Ana Guadaño at the Alberto Sols Biomedical Research Institute (IIBM, a combined CSIC-UAM center) and involving the Complutense University of Madrid (UCM), used CRISPR gene editing techniques to incorporate into the mice a mutation of the MCT8 protein responsible for transporting thyroid hormones to the interior of the cell.

Signaling pathway within brain cells regulates sleep

A good night's sleep can work wonders for both mind and body. But what is it that determines how much we need to sleep, and what can cause us to sleep more deeply?

New method uses light to change long-term behavior of neurons

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and MIT have developed a new method to target diseased neurons in the brain and change their long-term behavior using light, paving the way for potential new treatments for neurological conditions such as epilepsy and autism.
