CT Radiation Study

Full study title: Low Dose Ionizing Radiation Using CT Scans as a Potential Therapy for Dementia (LDIR-CT-Dementia) Trial: A Pilot Study

 

What is the study about?

This study is a randomized control trial that is trying to find out whether the radiation from repeated CT scans can temporarily improve the functioning, memory, thinking, and/or behaviour in people with advanced dementia. A CT scan sends out a low dose of radiation. In this study, depending on the group a participant is placed in and how long they participate, a participant could receive up to eight CT scans over several weeks.

 

Eligibility- Who can participate?

Participants must:

• Be in advanced stage of dementia (the study team will do a short assessment to determine eligibility)
• Have a study partner who can also participate; the study partner will play an important role and must be someone who regularly spends time with the participant—at least several times a week
• Have been clinically stable for the last 3 months

 

Time requirement

• There are two phases that are 13 weeks each. If you choose to participate in both phases, it is 26 weeks in total. Study visits are approximately once a week (but there are some breaks with no activity for three weeks). In addition to CT scans, participants will also undergo cognitive testing, blood draws, and electroencephalography (EEG).
