Early Promise For Stroke Patients GivenSeptember 05, 2001A preliminary study published in this week’s issue of THE LANCET suggests that the neurotransmitter precursor levodopa used in combination with physiotherapy could improve motor recovery for patients after stroke. Hemiplegia (paralysis to one side of the body) causes functional disability after stroke. Physiotherapy used to be the only way of improving motor function in such patients. However, administration of amphetamines in addition to exercise has been found to improve motor recovery in animals, probably by increasing the concentration of the neurotransmitter norepinephrine in the central nervous system. Klaus Scheidtmann and colleagues from Bad Aibling Neurological Hospital, Germany, investigated whether levodopa could enhance the efficacy of physiotherapy after hemiplegia. 53 primary stroke patients were assessed in a prospective, randomised study. For the first 3 weeks patients received single doses of 100 mg levodopa or placebo daily in combination with physiotherapy. For the second 3 weeks patients had only physiotherapy. Motor function was assessed every week by Rivermead motor assessment (RMA). Motor recovery was substantially improved after 3 weeks of drug intervention in patients given levodopa (RMA improved by 6.4 points) compared with placebo (4.1), and the result was independent of initial degree of impairment. The advantage of the levodopa group was maintained 3 weeks after levodopa was stopped. At the end of the study the total RMA score gain for the levodopa group was 8.2 points compared with 5.7 in the placebo group. Friedemann Müller (one of the investigators) comments: “A single dose of levodopa was well tolerated and, when given in combination with physiotherapy, was found to enhance motor recovery in patients with hemiplegia. This trend should be confirmed, and we need to establish long-term ceiling effects, which our short observation period did not allow us to judge. We should also ascertain to what extent the lesion size and amount of levodopa affect enhanced functional recovery. In view of its minimal side-effects, levodopa will be a possible add- on during stroke rehabilitation.” Lancet |

New discovery about the formation of new brain cells The generation of new nerve cells in the brain is regulated by a peptide known as C3a, which directly affects the stem cells' maturation into nerve cells and is also important for the migration of new nerve cells through the brain tissue, reveals new research from the Sahlgrenska Academy published in the journal Stem Cells. Multiple health concerns surface as winter, vitamin D deficiences arrive A string of recent discoveries about the multiple health benefits of vitamin D has renewed interest in this multi-purpose nutrient, increased awareness of the huge numbers of people who are deficient in it, spurred research and even led to an appreciation of it as "nature's antibiotic." New understanding about mechanism for cell death after stroke leads to possible therapy Scientists at the Brain Research Centre, a partnership of the University of British Columbia Faculty of Medicine and Vancouver Coastal Health Research Institute, have uncovered new information about the mechanism by which brain cells die following a stroke, as well as a possible way to mitigate that damage. Surgery not linked to memory problems in older patients For years, it has been widely assumed that older adults may experience memory loss and other cognitive problems following surgery. But a new study from researchers at Washington University School of Medicine in St. Louis questions those assumptions. Pushing the brain to find new pathways Until recently, scientists believed that, following a stroke, a patient had about six months to regain any lost function. After that, patients would be forced to compensate for the lost function by focusing on their remaining abilities.
