Hypertension Drugs Could Prevent Memory Loss in Lupus Patients, Study Suggests

Researchers from The Feinstein Institute for Medical Research have discovered that the activation of brain cells called microglia likely contributes to the memory loss and other cognitive impairments suffered by many patients with systemic lupus erythematosus (SLE). The study, which will be published September 5 in the Journal of Experimental Medicine, shows that ACE inhibitors—a class of drugs commonly used to treat hypertension—can block this process in mice and might therefore

Non-Invasive Brain Stimulation May Help Treat Symptoms of Rare Movement Disorders

Electrical stimulation of the brain and spinal cord may help treat the symptoms of rare movement disorders called neurodegenerative ataxias, according to a study published in the August 22, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology. There are several types of these disorders, which can be hereditary or occur randomly, including spinocerebellar ataxia, multiple system atrophy and Friedreich’s ataxia. Symptoms of ataxias include a lack

Cleveland Clinic Researchers Discover Novel Subtype of Multiple Sclerosis

New findings published in The Lancet Neurology  Cleveland Clinic researchers have discovered a new subtype of multiple sclerosis (MS), providing a better understanding of the individualized nature of the disease. MS has long been characterized as a disease of the brain’s white matter, where immune cells destroy myelin – the fatty protective covering on nerve cells. The destruction of myelin (called demyelination) was believed to be responsible for nerve cell (neuron)

Defect in Debilitating Neurodegenerative Disease Reversed in Mouse Nerves

Scientists have developed a new drug compound that shows promise as a future treatment for Charcot-Marie-Tooth disease, an inherited, often painful neurodegenerative condition that affects nerves in the hands, arms, feet and legs. The researchers used the compound to treat the nerves of mice harboring the genetic defects that cause the disease. The new study, from Washington University School of Medicine in St. Louis, challenges some conventional wisdom regarding how

Preliminary Study Suggests Drug May Help Babies with Spinal Muscular Atrophy

A preliminary study suggests that an investigational drug may help increase protein levels in babies with spinal muscular atrophy. The open-label study is released today and will be presented at the American Academy of Neurology’s 70th Annual Meeting in Los Angeles, April 21 to 27, 2018. Spinal muscular atrophy (SMA) is an inherited disease that leads to loss of motor function. It is the leading genetic cause of death in

A Single Concussion May Increase Risk of Parkinson’s Disease

People who have been diagnosed with a mild concussion, or mild traumatic brain injury, may have a 56 percent increased risk of developing Parkinson’s disease, according to a study published in the April 18, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology. “Previous research has shown a strong link between moderate to severe traumatic brain injury and an increased risk of developing Parkinson’s disease

Novel Mechanism Found In a Severe Childhood Neurodegeneration

Neurology researchers investigating a rare but devastating neurological regression in infants have discovered the cause: gene mutations that severely disrupt crucial functions in mitochondria, the energy-producing structures within cells. The specific disease mechanism, in which mutations disrupt a critical mitochondrial enzyme, has not previously been implicated in a human disease. “We uncovered the cause of this mysterious neurodegenerative disease, and now we understand better what happens in the brains of

FDA authorizes marketing of first blood test to aid in the evaluation of concussion in adults

The U.S. Food and Drug Administration today permitted marketing of the first blood test to evaluate mild traumatic brain injury (mTBI), commonly referred to as concussion, in adults. The FDA reviewed and authorized for marketing the Banyan Brain Trauma Indicator in fewer than 6 months as part of its Breakthrough Devices Program. Most patients with a suspected head injury are examined using a neurological scale, called the 15-point Glasgow Coma

Potential New Autism Drug Shows Promise in Mice

Scientists have performed a successful test of a possible new drug in a mouse model of an autism disorder. The candidate drug, called NitroSynapsin, largely corrected electrical, behavioral and brain abnormalities in the mice. NitroSynapsin is intended to restore an electrical signaling imbalance in the brain found in virtually all forms of autism spectrum disorder (ASD). “This drug candidate is poised to go into clinical trials, and we think it

Newly described process in Parkinson’s protein as a potential new therapy route

An international group of researchers led by Professor Wim Versées (VIB-VUB) has unraveled the workings of an essential mechanism in 'Parkinson's protein' LRRK2. Their study demonstrates a direct link between the protein's 'dimerization' - two copies that are bound together -and mutations that lead to Parkinson's disease. This process could eventually lead to a promising therapy route. This research has been published in the leading academic journal Nature Communications. Approximately 4

Better ‘Mini Brains’ Could Help Scientists Identify Treatments for Zika-Related Brain Damage

UCLA researchers develop improved technique for creating brain tissue from stem cells UCLA researchers have developed an improved technique for creating simplified human brain tissue from stem cells. Because these so-called “mini brain organoids” mimic human brains in how they grow and develop, they’re vital to studying complex neurological diseases. In a study published in the journal Cell Reports, the researchers used the organoids to better understand how Zika infects and

Gene Identified That May Provide Potential Therapy for Cerebral Cavernous Malformations

Researchers at University of California San Diego School of Medicine, with national collaborators, have identified a series of molecular clues to understanding the formation of cerebral cavernous malformations (CCMs). The study offers the first genome-wide analysis of the transcriptome of brain microvascular endothelial cells after KRIT1 inactivation. Findings were published September 28 in the Journal of Experimental Medicine. “These mouse studies reveal a critical mechanism in the pathogenesis of cerebral

Biologists Find New Source for Brain’s Development

A team of biologists has found an unexpected source for the brain’s development, a finding that offers new insights into the building of the nervous system. The research, which appears in the journal Science, discovered that glia, a collection of non-neuronal cells that had long been regarded as passive support cells, in fact are vital to nerve-cell development in the brain. “The results lead us to revise the often neuro-centric

Stabilizing TREM2 — a potential strategy to combat Alzheimer’s disease

A gene called triggering receptor expressed on myeloid cells 2, or TREM2, has been associated with numerous neurodegenerative diseases, such as Alzheimer's disease, Frontotemporal lobar degeneration, Parkinson's disease, and Nasu-Hakola disease. Recently, a rare mutation in the gene has been shown to increase the risk for developing Alzheimer's disease. Independently from each other, two research groups have now revealed the molecular mechanism behind this mutation. Their research, published today in EMBO
