This only tested one person who acquired prosopagnosia following a brain injury.

Prosopagnosia (face blindness) may be temporarily improved following inhalation of the hormone oxytocin.
This is the finding of research led by Dr Sarah Bate and Dr Rachel
Bennetts of the Centre for Face Processing Disorders at Bournemouth
University that will be presented today, Friday 6 September, at the
British Psychological Society’s Joint Cognitive and Developmental
annual conference at the University of Reading.
Dr Bate explained: “Prosopagnosia is characterised by a severe
impairment in face recognition, whereby a person cannot identify the
faces of their family or friends, or even their own face”
The researchers tested twenty adults (10 with prosopagnosia and 10
control participants). Each participant visited the laboratory on two
occasions, approximately two weeks apart. On one visit they inhaled
the oxytocin nasal spray, and on the other visit they inhaled the
placebo spray. The two sprays were prepared by an external
pharmaceutical company in identical bottles, and neither the
participants nor the researchers knew the identity of the sprays until
the data had been analysed.
Regardless of which spray the person inhaled, the testing sessions
had an identical format. Participants inhaled the spray, then sat
quietly for 45 minutes to allow the spray to take effect. They then
participated in two face processing tests: one testing their ability to
remember faces and the other testing their ability to match faces of
the same identity.
The researchers found that the participants with prosopagnosia
achieved higher scores on both face processing tests in the oxytocin
condition. Interestingly, no improvement was observed in the control
participants, suggesting the hormone may be more effective in those
with impaired face recognition systems.
The initial ten participants with prosopagnosia had a developmental
form of the condition. Individuals with developmental prosopagnosia
have never experienced brain damage, and this form of face blindness is
thought to be very common, affecting one in 50 people. Much more
rarely, people can acquire prosopagnosia following a brain injury. At a
later date, the researchers had the opportunity to test one person
with acquired prosopagnosia, and also observed a large improvement
following oxytocin inhalation in this individual.
Dr Bate said: “This study provides the first evidence that oxytocin
may be used to temporarily improve face recognition in people with
either developmental or acquired prosopagnosia. The effects of the
hormone are thought to last 2-3 hours, and it may be that the nasal
spray can be used to improve face recognition on a special occasion.
However, much more research needs to be carried out, as we don’t
currently know whether there are benefits or risks associated with
longer-term inhalation of the hormone.”
Use the labels in the right column to find what you want. Or you can go thru them one by one, there are only 29,116 posts. Searching is done in the search box in upper left corner. I blog on anything to do with stroke.DO NOT DO ANYTHING SUGGESTED HERE AS I AM NOT MEDICALLY TRAINED, YOUR DOCTOR IS, LISTEN TO THEM. BUT I BET THEY DON'T KNOW HOW TO GET YOU 100% RECOVERED. I DON'T EITHER, BUT HAVE PLENTY OF QUESTIONS FOR YOUR DOCTOR TO ANSWER.
Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.
What this blog is for:
My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.
