Reversible Brain Sagging Dementia: A Two Case Report

Although rare, BSD should be considered as a differential diagnosis when a bvFTD is suspected. Headache should be considered a red flag for BSD; however, it can be absent. CT-M appears superior to spine MRI for locating CSF leaks. In BSD, identifying the site of the CSF leak and performing a TBP seems to have better outcomes. Our results suggest that a shorter period of time between symptom onset and treatment results in better outcomes. In BSD, as a reversible cause of dementia, efforts must be made towards the correct diagnosis and timely treatment.
