Brief summary
This study will evaluate the effects on emotions and neural activity of a one time dose of intranasal oxytocin vs. placebo in patients with FTD and healthy controls.
Detailed description
Frontotemporal dementia (FTD) and Pick's disease cause changes in personality, behaviour, and emotional responses. The usual treatments for Frontotemporal dementia focus on reducing agitation and aggressive behaviours. However, these drugs do not help all patients who experience blunting of emotion and loss of empathy. This study will evaluate the effects on emotions and neural activity of a one time dose of intranasal oxytocin vs. placebo in patients with FTD and healthy controls.
Interventions
Oxytocin can be given intravenously (with a needle) or intranasally (a spray into the nose). The intravenous form of drug is approved by Health Canada for use in pregnancy. The intranasal formulation is not currently approved for use by Health Canada, but is used in Europe to induce labour in pregnant women or aid lactation (breastfeeding). Participants will be randomized to receive 72 IU intranasal oxytocin on either study visit 2 or 3.
Participants will be randomized to receive placebo on either study visit 2 or 3.
