EEG Biomarker for Alzheimer’s Disease
Alzheimer’s disease (AD) is a neurodegenerative disorder that accounts for nearly 70% of the more than 50 million dementia cases estimated worldwide. There is no cure for AD. Currently, AD diagnosis is carried out using neuropsychological tests, neuroimaging scans, and laboratory tests. In the early stages of AD, brain computed tomography (CT) and magnetic resonance imaging (MRI) findings may be normal, but in late periods, diffuse cortical atrophy can be detected more prominently in the temporal and frontal regions. Electroencephalogram (EEG) is a test that records the electrical signals of the brain by using electrodes that directly reflects cortical neuronal functioning. In addition, EEG is noninvasive and widely available at low cost, has high resolution, and provides access to neuronal signals, unlike functional MR or PET which indirectly detects metabolic signals. Accurate, specific, and cost-effective biomarkers are needed to track the early diagnosis, progression, and treatment response of AD. The findings of EEG in AD are now identified as biomarkers. In this chapter, we reviewed studies that used EEG or event-related potential (ERP) indices as a biomarker of AD

Effects of Lacosamide in Cerebral Tuberculoma-Induced Nonconvulsive Status Epilepticus: Case Report
Nonconvulsive status epilepticus (NCSE) is characterized by unexplained changes in behavior and mental status accompanied with continuous seizure activity seen on electroencephalography (EEG). Treatment is similar to treatment of status epilepticus. Lacosamide is one of the newer antiepileptic drugs (AEDs) that slow inactivation of voltage-dependent sodium channels. It has high oral bioavailability, is low protein binding and is primarily metabolized by the liver enzyme CYP2C19. Central nervous system (CNS) tuberculosis may present with signs of parenchymal lesions instead of meningitis. Presently described is a patient who was diagnosed as CNS tuberculosis a year ago with nonconvulsive status epilepticus. Status could be not be controlled with levetiracetam; however, use of lacosamide successfully resolved nonconvulsive status epilepticus
