Nanoscale coordination polymers show promise for efficient dopamine delivery in Parkinson's treatment

Parkinson's disease (PD) is a common neurodegenerative disorder caused by the death of dopaminergic neurons in a part of the brain (known as substantia nigra pars compacta), which leads to a deficit of dopamine (DA), one of the main neurotransmitters active in the central nervous system.

UTokyo researchers study worms to understand the neuroplasticity of learning

As anyone who has ever procrastinated knows, remembering that you need to do something and acting on that knowledge are two different things. To understand how learning changes nerve cells and leads to different behaviors, researchers studied the much simpler nervous system of worms.

Little-known illnesses turning up in Covid long-haulers

The day Dr. Elizabeth Dawson was diagnosed with covid-19 in October, she awoke feeling as if she had a bad hangover. Four months later she tested negative for the virus, but her symptoms have only worsened.

Cognitive reappraisal may reduce compulsive drug-seeking behavior in cocaine-addicted individuals

An emotion regulation strategy known as cognitive reappraisal helped reduce the typically heightened and habitual attention to drug-related cues and contexts in cocaine-addicted individuals, a study by Mount Sinai researchers has found.

Researchers discover a new and unique form of ALS

In a study of 11 medical-mystery patients, an international team of researchers led by scientists at the National Institutes of Health and the Uniformed Services University discovered a new and unique form of amyotrophic lateral sclerosis (ALS).

Inflammatory brain injury higher in men with acute COVID-19, finds study

The COVID-19 pandemic has been associated with both short- and long-term neurologic complications, including stroke, brain fog and persistent tiredness. A new study concludes that the effects of SARS-CoV-2 on the central nervous system (CNS) are due to the endothelial injury and inflammation that this produces in the brain.

UVA researchers shed new light on brain development

University of Virginia School of Medicine researchers have shed new light on how our brains develop, revealing that the very last step in cell division is crucial for the brain to reach its proper size and function.

Neuropathology of COVID-19 patients caused by infection of brain pericytes

Recently, researchers from the UK and Sweden used highly sensitive multiplexed immunohistochemistry to study the brain tissue of COVID-19 patients and controls to analyze ACE2 expression in brain pericytes of patients with neurological symptoms. They also used spatial immunophenotyping to assess inflammation in brain tissue of COVID-19 patients.

Vagus nerve stimulation may be a potential adjunct therapy for COVID-19

COVID-19 was initially described as lung inflammation, or pneumonia, in older adults. However, we now know that SARS-CoV-2 infections can cause a wide range of symptoms in people of all ages, ranging from no symptoms at all to systemic inflammation and even death.

Neurocognitive symptoms persist 6 months post-infection with long COVID

According to the World Health Organization (WHO), COVID-19 long-haulers are people who experience symptoms such as body ache, fatigue, shortness of breath, headache, difficulty concentrating, loss of taste or smell, or other health issues long after they test negative for the virus. It can be defined as having serious and prolonged symptoms three months after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Researchers to conduct Phase 1 gene therapy trial to treat Alzheimer's disease

The National Institute on Aging (NIA), part of the National Institutes of Health, has awarded a $5 million grant to researchers at University of California San Diego School of Medicine to conduct a first-in-human Phase 1 clinical trial of a gene therapy for treating Alzheimer's disease (AD) or Mild Cognitive Impairment (MCI), a condition that often precedes full-blown dementia.

University of Freiburg professor honored for groundbreaking results on the brain’s immune system

The blood-brain barrier is an impenetrable barrier between the circulating blood and the brain established before birth that prevents immune cells from entering the brain from the body's immune system. Thus, the brain has its own immune system with a key actor called microglia.
