Varicella zoster virus primary infection (chickenpox), the virus goes dormant in the nerves, including the cranial nerve ganglia, dorsal root ganglia, and autonomic ganglia. Many years after the person has recovered from chickenpox, VZV can reactivate to cause neurologic conditions. Primary varicella zoster virus infection results in chickenpox (varicella), which may result in complications including encephalitis, pneumonia (either direct viral pneumonia or secondary bacterial pneumonia), or bronchitis (either viral bronchitis or secondary bacterial bronchitis). Even when clinical symptoms of chickenpox have resolved, VZV remains dormant in the nervous system of the infected person (virus latency), in the trigeminal and dorsal root ganglia. VZV
Short-term memory study which compiled normative French data for three short-term memory tasks (Verbal, visual and spatial). They found impairments present in participants between the ages of 55 and 85 years of age. Memory distortion in Alzheimer's disease is a very common disorder found in older adults. Performance of patients with mild to moderate Alzheimer's disease was compared with the performance of age matched healthy adults. Researchers concluded the study with findings that showed reduced short-term memory recall for Alzheimer's patients. Episodic memory and semantic abilities deteriorate early in Alzheimer's disease. Since the cognitive system includes interconnected and reciprocally influenced neuronal networks,
