Varicella vaccine seen in children. The incidence of herpes zoster in vaccinated adults is 0.9/1000 person-years, and is 0.33/1000 person-years in vaccinated children; this is lower than the overall incidence of 3.2–4.2/1000 person-years. Adult shingles cases may increase after introduction of varicella vaccine, but evidence is unclear. While research using computer models has tended to support the hypothesis that vaccination programs would increase incidence of zoster in the short term, the evidence from epidemiological studies is mixed, and increases observed in zoster incidence in some studies may not be related to vaccination programs, as the incidence increases prior to the varicella vaccine
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,
