Covert and recurrent strokes increase during aging, emphasizing the importance of using aged rodent models of recurrent stroke. In experiment 1, 25 young and 16 middle-aged Sprague Dawley rats underwent medial prefrontal cortex (mPFC) or sham ischemia. There was no overt motor effect of mPFC ischemia, making it a valid model of covert stroke. Notably, middle-aged rats showed decreased overall performance in the staircase reaching test, relative to younger rats. In experiment 2, 34 young and 33 middle-aged rats underwent middle cerebral artery occlusion (MCAo) +/- mPFC ischemia. Unlike experiment 1, there was no effect of age on baseline performance. The middle-aged group, however, had less motor impairments and significantly smaller striatal infarcts, suggesting the MCAo strokes were suboptimal. These results highligh important age-related differences in post-stroke performance. Behavioural outcome measures, motivation level and the ischemic model must be carefully considered in developing older animal models of stroke.

In view of the numerous failures of clinical trials aimed at improving stroke therapy, the role and potential benefit of experimentally modeling focal cerebral ischemia in rodents has been debated. When methods of systematic review and metaanalyis are applied, however, it turns out that experimental models actually faithfully predicted the negative outcomes of clinical trials. In addition, thrombolysis and neuroprotection by hypothermia, first described in animal models, are key examples of treatment modalities that have made it successfully into clinical practice. In Rodent Models of Stroke, an international consortium of authors aims at critically addressing the issues on a very practical level, from choosing the model and outcome measures, designing the experiment, conducting and analyzing it, to reporting it in a scientific publication. The structure and content of the book reflect both the authors’ longstanding expertise in experimental and clinical stroke research and their roles in training the scientific community in the tools of the trade. As a volume in the successful Neuromethods series, the chapters provide authoritative reviews of the most commonly used, well-honed approaches in the field today. Stimulating and easy-to-use, Rodent Models of Stroke will help its readers understand the limitations and the opportunities of modeling stroke in rodents and enable them to conduct experiments which will not only improve our understanding of the pathophysiology of this devastating disorder but also serve as the basis for developing new highly effective treatments.

This open access book focuses on practical clinical problems that are frequently encountered in stroke rehabilitation. Consequences of diseases, e.g. impairments and activity limitations, are addressed in rehabilitation with the overall goal to reduce disability and promote participation. Based on the available best external evidence, clinical pathways are described for stroke rehabilitation bridging the gap between clinical evidence and clinical decision-making. The clinical pathways answer the questions which rehabilitation treatment options are beneficial to overcome specific impairment constellations and activity limitations and are well acceptable to stroke survivors, as well as when and in which settings to provide rehabilitation over the course of recovery post stroke. Each chapter starts with a description of the clinical problem encountered. This is followed by a systematic, but concise review of the evidence (RCTs, systematic reviews and meta-analyses) that is relevant for clinical decision-making, and comments on assessment, therapy (training, technology, medication), and the use of technical aids as appropriate. Based on these summaries, clinical algorithms / pathways are provided and the main clinical-decision situations are portrayed. The book is invaluable for all neurorehabilitation team members, clinicians, nurses, and therapists in neurology, physical medicine and rehabilitation, and related fields. It is a World Federation for NeuroRehabilitation (WFNR) educational initiative, bridging the gap between the rapidly expanding clinical research in stroke rehabilitation and clinical practice across societies and continents. It can be used for both clinical decision-making for individuals and as well as clinical background knowledge for stroke rehabilitation service development initiatives.

Subcortical Stroke is a new and fully revised edition of Lacunar and Other Subcortical Infarctions (OUP, 1995). Stroke is one of the most common causes of death and subcortical stroke accounts for 20-30% of all cerebrovascular infarctions. Our understanding of stroke processes in general, and subcortical stroke in particular, has advanced considerably in recent years. Research findings from the fields of neurochemistry, imaging and genetics have provided insight and input to our understanding of this condition, and this new edition provides an opportunity to describe these advances, and to relate the findings to the clinical expression, neural mechanism, prognosis and treatment of subcortical stroke. In addition, new subcortical syndromes such as CADASIL are covered, as is subcortical haemorrhage. This book presents a comprehensive and authoritative review of the field with contributions from the leading international experts. Subcortical Stroke is for stroke physicians, neurologists and those researching cerebrovascular diseases.

Increasing evidence identifies the possibility of restoring function to the damaged brain via exogenous therapies. One major target for these advances is stroke, where most patients can be left with significant disability. Treatments have the potential to improve the victim's quality of life significantly and reduce the time and expense of rehabilitation. Brain Repair After Stroke reviews the biology of spontaneous brain repair after stroke in animal models and in humans. Detailed chapters cover the many forms of therapy being explored to promote brain repair and consider clinical trial issues in this context. This book provides a summary of the neurobiology of innate and treatment-induced repair mechanisms after hypoxia and reviews the state of the art for human therapeutics in relation to promoting behavioral recovery after stroke. Essential reading for stroke physicians, neurologists, rehabilitation physicians and neuropsychologists.
