Researchers from University of California - Los Angeles have found that drug Aricept, used to treat Alzheimer's symptoms, can help in mild memory loss also. They recruited a small sample of adults with mild age-related memory loss and randomly assigned them a daily placebo or Aricept.
Both groups underwent Positron emission technology (PET) brain scans before and after 18 months of treatment.
The research team found that people, who were given Aricept showed an increased rate of metabolism and looked more normal than the brains of those who took the placebo.
Moreover, both the groups scored the same on memory tests, however, implying that PET scans may be more sensitive than neuropsychological tests in detecting drugs' effects.
The researchers suggest that the treatment of early symptoms of memory loss may protect the brain and help people with mild age-related memory impairment.
The finding also shows how PET offers researchers a tool for tracking the effectiveness of drugs prescribed to treat age-related cognitive decline.
