The differential diagnosis of meningitis and encephalitis includes bacterial, viral, fungal, and autoimmune etiologies. Comparisons may be useful for a differential diagnosis: Focal cortical dysplasia in the motor region refers to lesions near the motor-sensory cortex that can provoke EPC which is similar to RE. Lower costs and increasing accessibility of these technologies will facilitate larger studies of these patients. Diagnosis During the first phase of the disease, the most common laboratory abnormalities are a low white blood cell count (leukopenia) and a low platelet count (thrombocytopenia). In the California Encephalitis Project, an underlying cause of encephalitis was not identified in 208 (62%) of 334 patients during 1998–2000, despite extensive testing and evaluation ; of note, ∼10% of patients initially thought to have an infectious cause of their encephalitis ultimately received a diagnosis of a noninfectious condition.
