Additional Study Information: Columbia Medical Center is recruiting for a study to test whether the drug oxytocin can improve symptoms of emotion and behavior (e.g. apathy) in people with frontotemporal dementia. The study will last for up to 24 weeks (6 months). This is a crossover study, which means that each participant will receive both oxytocin and placebo (medically inactive substance). Over the course of three months, the participant will come in five times with a study partner, who may be a family member or friend, for medical, behavioral and cognitive assessment. There will be a blood draw at each visit, and an optional lumbar puncture (spinal tap) at two visits. Each visit will last 3-5 hours. Participation and transportation costs will be reimbursed.
