Description: Scientists say mice genetically altered to develop an Alzheimer's-like illness undergo "silent" brain seizures. According to researchers at the Baylor College of Medicine and the Gladstone Institute of Neurological Disease, the seizures may explain why some people with advanced Alzheimer's have "spells" of increased confusion. The seizures observed in the mice would not be recognizable in the same way a convulsion or epileptic seizure can be noticed.
