Botulinum Toxin a Shot in the Arm for Preventing MS Tremor

03.07.2012
Botulinum toxin may help prevent shaking or tremor in the arms and hands of people with multiple sclerosis (MS), according to new research published in the July 3, 2012, print issue of Neurology®, the medical journal of the American Academy of Neurology.

“Treatments in use for tremor in MS are not sufficiently effective and new alternatives are needed,” said study author Anneke van der Walt, MD, consultant neurologist at The Royal Melbourne Hospital and research fellow with the University of Melbourne in Australia.

For the study 23 people with MS were given botulinum toxin type A injections or a saline placebo for three months. Then they received the opposite treatment for the next three months. Scientists measured the tremor severity and their ability to write and draw before, during and after receiving the treatments. Video assessments were also taken every six weeks for six months.

The study found that people saw significant improvement in tremor severity, writing and drawing at six weeks and three months after the botulinum toxin treatment compared to after placebo. In tremor severity, the participants improved an average of two points on a 10-point scale, bringing their tremor from moderate to mild. In writing and drawing, participants improved by an average of one point on a 10-point scale.

“Our study suggests a new way to approach arm tremor related to MS where there are currently major treatment challenges and it also sets the framework for larger studies,” said van der Walt.

Muscle weakness developed in 42 percent of people after treatment with botulinum toxin compared to six percent after placebo. The weakness was generally mild and went away within two weeks.

The study was supported by the Box Hill MS Research Fund and The Royal Melbourne Hospital Neuroscience Foundation.

The American Academy of Neurology, an association of more than 25,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer’s disease, stroke, migraine, multiple sclerosis, brain injury, Parkinson’s disease and epilepsy.

Im Focus: Strathclyde-led research develops world's highest gain high-power laser amplifier

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.

The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
