Norton Neuroscience Institute Expands Parkinson’s Care, Research

Due in large part to a $15 million Norton Healthcare Foundation investment, the Norton Neuroscience Institute (NNI) has expanded to offer state-of-the-art technologies and enhanced amenities for people with Parkinson’s and other neurological diseases. The newly opened center at the Louisville, Kentucky-based nonprofit institute, which serves its regional community,…

How Nerve Cells Damaged at Disease Onset Goal of EU Project

An almost €2 million (about $2.3 million) EU-funded project is advancing the understanding of how damaged or abnormal cell parts are removed at the synapses, a process known as synapse-specific autophagy, and how defects in this mechanism contribute to neurodegenerative disorders such as Parkinson’s disease and Alzheimer’s. Synapses,…

Uric Acid May Help to Protect Neurons, Ease Non-motor Symptoms

Among people with Parkinson’s disease, those with low blood levels of uric acid — a natural antioxidant — tend to have more severe non-motor symptoms like anxiety, depression, and cognitive dysfunction, a study indicates. It also showed a link between uric acid levels and gray matter volume in the…

Non-invasive ‘Smell’ Test May Speed Diagnosis

A non-invasive test that measures signals from the olfactory bulb — the part of the brain responsible for scent-perception — may aid in the early diagnosis of Parkinson’s disease, according to a recent study. The test, called an electrobulbogram, also also can inform about disease duration, severity, and the…

Electrical Stimulation of Brain via Scalp May Ease Bradykinesia

Electrical stimulation given through the scalp to a brain region called the supplementary motor area may ease certain aspects of upper limb bradykinesia in people with Parkinson’s disease, a small study suggests. The study, “Transcranial direct current stimulation of supplementary motor area improves upper limb kinematics…

Excess Alpha-synuclein Directly Linked to Mitochondrial Problems

Higher-than-normal levels of alpha-synuclein — the protein that accumulates in toxic clumps in Parkinson’s disease — affect the shape, dynamics, and health of mitochondria, which are the powerhouses of the body’s cells, according to a study in a fruit fly model. “When fruit fly larvae expressed alpha-synuclein at elevated…
