Study suggests prenatal origin for ‘young’ Parkinson’s disease

A new study published in the journal Nature Medicine on January 2020 suggests that Parkinson’s disease developing before the age of 50 years could be due to an abnormality in certain brain cells that remains dormant until the age of onset of the disease. It also indicates the potential usefulness of a specific drug to prevent this by correcting the brain cell disorder.

Parkinson's disease may affect brain cells before birth

People who develop Parkinson's disease before age 50 may have been born with disordered brain cells that went undetected for decades, according to new Cedars-Sinai research. The research points to a drug that potentially might help correct these disease processes.

Potential Parkinson's treatment effectively targets a specific group of brain cells

Scientists have discovered that a non-invasive technique which could one day be used to treat Parkinson's disease, can successfully target a highly specific group of brain cells which play a key role in development of the condition.

Gut microbiome linked to behavioral problems in children

Children with behavioral problems may have different compositions in their gut microbiome, with parents playing a major role in how pronounced the differences were, other than the food they provide, a new study suggests.

New analysis method shows how the brain regulates its signals using glutamate

Researchers at Chalmers University of Technology and Gothenburg University in Sweden have achieved something long thought almost impossible - counting the molecules of the neurotransmitter glutamate released when a signal is transferred between two brain cells. With a new analysis method, they showed that the brain regulates its signals using glutamate in more ways than previously realised.

Researchers identify how certain areas of the brain respond to ADHD drug

Attention-deficit hyperactivity disorder is a neurobiological disorder characterized by symptoms of hyperactivity, inattention and impulsivity.

Researchers find potential new target for treating drug addiction

New University of Minnesota Medical School research discovers a novel potential target for treating drug addiction through "the hidden stars of the brain."

Parkinson’s disease could be prevented by gut microbes

One common gut organism that helps us digest food better could also be a powerful instrument in preventing or reversing the symptoms of Parkinson’s disease (PD), according to a recent study. The changes are due to the ability of this bacterium to delay the build-up of a toxic protein involved in this in the disease condition, or even to eliminate the toxin altogether.

Sugar intake influences brain reward circuitry

The idea of food addiction is a very controversial topic among scientists. Researchers from Aarhus University have delved into this topic and examined what happens in the brains of pigs when they drink sugar water. The conclusion is clear: sugar influences brain reward circuitry in ways similar to those observed when addictive drugs are consumed.

Gut bacteria could protect against Parkinson’s, research suggests

A common bacteria that boosts digestive health can slow – and even reverse – build-up of a protein associated with Parkinson’s, new research suggests.

New study sheds light on storage and retrieval of hardwired long-term memory

Storing and retrieving memories is among the most important tasks our intricate brains must perform, yet how that happens at a molecular level remains incompletely understood.

Study shows dopamine signaling, biological clock connection in overconsumption and obesity

During the years 1976 through 1980, 15% of U.S. adults were obese. Today, about 40% of adults are obese. Another 33% are overweight.

GB Sciences announces preclinical results of promising formulations for Parkinson's disease

GB Sciences, Inc. announced significant preclinical results for their Parkinson's disease ("PD") formulations from the midterm report for their preclinical study being performed by Dr. Lee Ellis of the National Research Council in Halifax, Nova Scotia, CANADA.

Forgetful? Look at the time

An interesting new paper describes the discovery of a gene in mice that affects the degree of memory recall at various times of day. They found that this gene makes mice most forgetful at the time immediately before they wake.

Researchers identify first gene in mice specific to memory retrieval

Can't remember something? Try waiting until later in the day. Researchers identified a gene in mice that seems to influence memory recall at different times of day and tracked how it causes mice to be more forgetful just before they normally wake up.

Cancer drug shows promise in battling Parkinson’s disease

Parkinson’s disease (PD) is a lifelong condition that affects the nerve cells in the brain that produce dopamine. As a result, people with this neurodegenerative disease experience tremors, changes in speech, gait issues, and muscle rigidity. Though it has no cure, a new drug used to treat cancer shows promise in treating Parkinson’s.

Study shows nilotinib drug is safe and well tolerated in patients with Parkinson's disease

A clinical trial investigating the repurposed cancer drug nilotinib in people with Parkinson's disease finds that it is reasonably safe and well tolerated.

Neuroscientists develop new method for uniquely targeted gene therapy

Neuroscientists at Lund University in Sweden have developed a new technology that engineers the shell of a virus to deliver gene therapy to the exact cell type in the body that needs to be treated. The researchers believe that the new technology can be likened to dramatically accelerating evolution from millions of years to weeks.

Research reveals how skeletal muscle communicates with the brain regarding feeding behavior

The brain determines when it is time to feed - but how does it know? Findings from St. Jude Children's Research Hospital provide new understanding of how the brain orchestrates this process.
