Advanced use of MRI aids in accurate identification of rare, atypical parkinsonian disorders

by

An international study led by researchers from the Sant Pau Research Institute (IR Sant Pau) shows that advanced use of magnetic resonance imaging (MRI) allows much more accurate identification of patients with progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD). These are two rare and clearly underdiagnosed atypical parkinsonian disorders. The study, published in The Journal … Read more

New roadmap integrates aging into Parkinson disease models

by

Even though aging is the largest risk factor for Parkinson’s disease, the majority of research aimed at taming the able neurodegenerativeincur motor disease has largely left aging out of the mix. A group of researchers from around the globe seek to change that. “Unraveling the intersection of aging and Parkinson’s disease: a collaborative road map … Read more

Stem cell implants aim to restore dopamine in Parkinson’s disease

by

Parkinson’s disease is a progressive neurodegenerative disorder that affects more than one million people in the United States, with approximately 90,000 new cases diagnosed each year. Although available treatments can help manage symptoms, there is currently no cure or therapy proven to slow the progression of the disease.  Parkinson’s disease is associated with reduced dopamine release in the brain. Dopamine is a … Read more

Brain network discovery opens new path for Parkinson’s treatment

by

Parkinson’s disease, a progressive neurological disorder affecting more than 1 million people in the U.S. and more than 10 million globally, is characterized by debilitating symptoms such as tremors, movement difficulties, sleep disturbances and cognitive impairments. While current treatments, including long-term medication and invasive deep brain stimulation (DBS), can alleviate symptoms, they cannot halt progression … Read more

Study identifies brain region driving one-shot visual learning

by

Despite decades of research, the mechanisms behind fast flashes of insight that change how a person perceives their world, termed “one-shot learning,” have remained unknown. A mysterious type of one-shot learning is perceptual learning, in which seeing something once dramatically alters our ability to recognize it again. A new study, led by researchers at NYU … Read more

Regulating microglial phagocytosis through immunotherapy could slow Parkinson’s disease progression

by

By analyzing tissue from patients with Parkinson’s disease, and animal and cellular models of the disease, a research team from the Institut de Neurociències of the UAB has shown that the main immune cells of the brain become reactive and overexpress certain receptors that promote the elimination of dopaminergic neurons, even when these neurons are … Read more

Sleep disorders predict dementia risk years before diagnosis, study shows

by

New research reveals that sleep disorders can signal future risk of Alzheimer’s, Parkinson’s, and other dementias years before symptoms appear, offering hope for early intervention and prevention. Study: Sleep disturbances as risk factors for neurodegeneration later in life.

Ghrelin receptor identified as key to easing constipation in Parkinson’s patients

by

Considered the natural “hunger hormone”, Ghrelin could be the key to preventing debilitating chronic constipation experienced by people living with Parkinson’s disease, University of Queensland researchers have found. Associate Professor Sebastian Furness from the UQ School of Biomedical Sciences said the team discovered the body’s receptor for Ghrelin had a critical role in the normal … Read more

How deep brain stimulation alleviates symptoms of Parkinson’s

by
