A neurological disorder refers to a type of disorder that affects the nervous system. These disorders include multiple sclerosis, Alzheimer's disease and other dementias, Parkinson's disease, brain tumors, epilepsy, neuroinfections, and cerebrovascular diseases. There are several signs and symptoms of these disorders, such as muscle weakness, seizures, loss of sensation, paralysis and poor coordination. Neurological disorders are diagnosed using a variety of medical techniques, including positron emission tomography (PET), electroencephalography (EEG), single-photon emission computed tomography (SPECT), computerized tomography (CT scan) and magnetic resonance imaging (MRI scan). These medical technologies generate massive amounts of complex and high-dimensional data, which is a crucial source for planning therapies and treatments. Various advances in clinical practice and medical technologies are being developed, such as therapies with the potential to detect and treat Alzheimer's disease before its symptoms manifest, usage of stem cells for replacement therapy, and development of implantable wireless brain devices. This book unravels the recent studies on neurological disorders. It elucidates the advances in medical technology and clinical practice with respect to these disorders. Those in search of information to further their knowledge will be greatly assisted by this book.
