Signs of frozen gait are most noticeable when people with Parkinson’s disease  are turning or walking in a circle, and more noticeable when they are walking backward rather than forward, a small study reported. Three distinct characteristics of walking — step length, walking speed, and range of joint motion —…

A surgery-like brain procedure called gamma knife thalamotomy may help to ease tremor in people with Parkinson’s disease, a new study highlights. The study, “Gamma Knife stereotactic radiosurgery as a treatment for essential and parkinsonian tremor: long-term experience,” was published in Neurología. Tremor is one of…

A gene called Fer2 in fruit flies is essential for maintaining the health of dopamine-producing nerve cells and does so by supporting the cells’ mitochondria, which provide them with energy, a study reports. The human equivalent of this gene — a mammalian equivalent, called Nato3, was identified in mice — may…

SQZ Biotechnologies has received a $2 million grant to work out a way to turn a patient’s own immune cells into nerve cells (neurons) capable of producing dopamine, offering a new approach to treat Parkinson’s disease. Valid for two years, the Phase II grant for Small Business Innovation…

A real-time, home-monitoring system allowed for remote detection and management of orthostatic hypotension — a sudden drop in blood pressure when changing positions — in people with Parkinson’s disease during the COVID-19 pandemic, a pilot study shows. Notably, the eight patients involved reported these episodes profoundly affect daily life…

Some people with Parkinson’s disease have a characteristic genetic signature in a type of immune cell called memory T-cells, a new study suggests. “Parkinson’s disease is not usually seen as an autoimmune disease, but all of our work points toward T cells having a role in the disease,” Cecilia…

A form of the alpha-synuclein protein that can build up in the skin could help distinguish Parkinson’s disease from other neurodegenerative disorders, a study has found. Skin biopsy samples taken from Parkinson’s disease patients all showed a buildup of phosphorylated alpha-synuclein (p-syn), which is alpha-synuclein with an added phosphate…

A positron emission tomography (PET) tracer for the alpha-synuclein protein, whose damaging clumps mark Parkinson’s, captured its toxic aggregates in a living brain for a first time — instead of in post-mortem tissue as is done to date, scientists reported. The tracer, called ACI-12589, is a diagnostic tool designed to…

Combining a 12-week program of virtual reality (VR) training and motor imagery exercises with standard physical therapy (PT) significantly lessened motor symptoms — including tremors, slow movements (bradykinesia), and postural instability — among people with Parkinson’s disease, according to a recent study. “To the best of our knowledge, this…
