SCAN Trial Summary

This trial will test whether stimulating certain brain regions with a non-invasive method can help reduce fluctuations in alertness for people with Lewy body dementias, which are a major source of disability.

Eligible Conditions
  • Lewy Body Disease
  • Lewy Body Dementia

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Does this research endeavor extend to individuals who possess an age of sixty-five or above?

"To be considered for this investigation, applicants must fall within the range of 50 to 90 years old. Alternatively, there are 93 trials available for those younger than 18 and 813 studies suitable for aged individuals over 65."

Answered by AI

Do I qualify to join this scientific experiment?

"This trial seeks 18 participants between the age of 50 and 90 diagnosed with Lewy Body Disease. Additionally, these individuals must be on a stable dosage of cholinesterase inhibitors for at least 4 weeks prior to enrollment and meet either DLB or PDD criteria as defined by Emre et al. Specifically, those seeking inclusion in this study should demonstrate cognitive deficits in two out of four domains (attention, executive functions, visuo-spatial functions, free recall memory) plus one behavioral symptom such as apathy; however lack of behavioural symptoms does not bar them from participating. Other exclusionary conditions include coexistence of any abnorm"
