Reaction: neuroprosthesis helps Parkinson's patient to walk

A neuroprosthesis that electrically stimulates an area of the spinal cord of a man with Parkinson's disease improved his mobility and balance, according to results presented in Nature Medicine. The 62-year-old patient had severe difficulties walking and frequent falls, despite trying other treatments. After trials in non-human primates, this is the first time this technology has been tested in a human being, who has now been using the neuroprosthesis about eight hours a day for two years.

Reaction: Study finds tai chi may slow progression of Parkinson's disease

Research by researchers in Shanghai, China, suggests that continued practice of tai chi can slow the progression of Parkinson's disease symptoms and delay the need for increased doses of medication. The study compared 143 people who underwent tai chi training with 187 non-trainees who served as a control group. The results are published in the Journal of Neurology Neurosurgery & Psychiatry.

Reactions to the analysis linking certain gastrointestinal diagnoses with Parkinson's disease

Certain intestinal issues, such as constipation, difficulty swallowing, and irritable bowel syndrome, could be early warning signs of Parkinson's disease, according to a study published in the journal Gut. The study compared tens of thousands of patients from a network of medical records in the United States.

Reactions: movement data can predict Parkinson's risk years before diagnosis

Parkinson's disease is usually diagnosed when there is already extensive neuronal damage and symptoms are evident. Now, researchers at Cardiff University in the UK have used movement and sleep quality data from wearable accelerometers and concluded that they can help identify the disease early, years before clinical diagnosis. Although there is no effective preventive treatment, the authors propose that the tool can determine people at risk of developing Parkinson's disease and identify participants for clinical trials of neuroprotective treatments. The results are published in the journal Nature Medicine.

Reactions to clinical trial of Parkinson's drug to slow down ALS

A research team in Japan has published a small clinical trial in 20 people with amyotrophic lateral sclerosis (ALS) of a drug called ropinirole, which is commonly used in patients with Parkinson's disease. The authors, whose study is published in Cell Stem Cell, say the treatment is safe and slowed the progression of ALS - an incurable neurodegenerative disease - by an average of 27.9 weeks.

Reactions: New technique tested to improve gene therapy for Parkinson's disease

A study led by Spanish researchers and published in Science Advances has tested a new technique to improve gene therapy treatments for Parkinson's disease. Using ultrasound, they have managed to open the blood-brain barrier in specific areas, allowing the viruses used in the therapy to pass through and better reach the desired brain areas. After testing it on monkeys and three patients -patients were not given gene therapy, but the efficacy of the technique was tested using a radiotracer that does not normally cross the blood-brain barrier-, their conclusions are that the technique is safe and feasible and "could allow early and frequent interventions to treat neurodegenerative diseases".
