Australian scientists are confident magnenetic pulse brain stimulation research will help long-term stroke and Parkinson’s disease patients speak again. The approach, being pioneered by Professor Bruce Murdoch, Director of the Centre for Neurogenic Communication Disorders Research from the University of Queensland, uses magnetic pulses to stimulate damaged areas of the brain.
The technique, known as Transcranial Magnetc Stimulation – TMS – was previously used to treat depression and pain management. It’s the first time the therapy has been looked at for language or communication loss due to neurological damage.
The treatment is literally an on off switch for the brain, switching on brain function in Parkinson and off in stroke victims suffering from aphasia. TMS is a non-invasive method to cause depolarization or hyperpolarization in the neurons of the brain. TMS uses electromagnetic induction to induce weak electric currents using a rapidly changing magnetic field, causing activity in specific or general parts of the brain with minimal discomfort.
Aphasia in stroke victims is a condition where suffers have impaired language abilities, the range of the disorder includes memory difficulties for words, all the way through to a complete inability to speak
This isn’t a first for TMS use in Parkinsons or stroke, in 2009 Dr Jean-Pascal Le faucheur of Physiology department at Hospital Henri Mondor in France successfully used the therapy with pain management and Parkinsons :: Read the full article »»»»

Australian scientists have developed a new technique using stem cells, in the hope to replace damaged cells in Parkinson’s disease. The technique could be developed for application in other degenerative conditions.
Researchers at the University of Melbourne have made a breakthrough in the use of stem cells to treat Parkinson’s disease.Stem cells can be used to allow the body to produce dopamine, which prevents Parkinson’s.Until now, treatment has been too risky because some of the stem cells can become carcinogenic. Scientists have now found a way to identify and separate the therapeutic cells from the dangerous ones.
“We have made some recent progress in that area by identifying novel molecules on the therapeutic cells that allow us to target them and essentially pull them out and purify them,” said Dr Lachlan Thompson of the University of Melbourne. ”I think that will really potentially be an important breakthrough on the road to clinical translation.
