A woman with an exceptionally rare brain condition feels an overwhelming sense of familiarity with every person she encounters, including complete strangers. Jenny Parry, 54, from Scarborough, North Yorkshire, lives with hyperfamiliarity for faces (HFF), a neurological disorder that makes unknown individuals appear strikingly familiar. She is believed to be one of only a handful of people in Britain with the condition.
How the condition began
Jenny's symptoms first emerged seven years ago in autumn 2019, following a severe migraine while walking with her daughter at Painswick Rococo Garden in Gloucestershire. Immediately afterward, she felt she recognised the next person she saw. The zookeeper describes her brain as generating fake memories, making strangers seem like close friends she might have worked with, dined with, or even holidayed with.
She said: 'I had begun suffering a strong migraine on my usual right side, but then it spread to the left. And I haven't been the same since. After the headache, the next person I saw I thought I recognised them and I smiled, when really I had never met them before.'
Embarrassing encounters
The condition has led to awkward moments. Jenny recalled: 'This one time I was convinced I knew this woman from my old business as a circus choreographer. I had memories that we had spent a lot of time together and that I had been training her for years. I crossed the road and tapped her on the shoulder but she just looked at me bluntly. I apologised and went into my friend's nearby cafe and burst into tears as I was so embarrassed.'
She often feels overwhelmed in crowds and has struggled with self-esteem. 'Now my brain fires off these fake memories when I look at people's faces. My brain tells me I have been to the pub, to a concert, or on holiday when I see them, as if we had spent quality time together. But it can also feel very lonely at times because when I'm in a big crowd of people, I feel like I'm the only one there.'
Scientific research
Neuroscientists at the University of York, working with Dartmouth University in the USA, studied Jenny's brain using neuroimaging. They showed her clips from Game of Thrones, which she had never watched, and compared her brain activity to fans and those unfamiliar with the show. Results revealed that her hippocampus, a memory region, responded as if she recognised the characters, despite never having seen them.
Professor Tim Andrews from the University of York explained: 'Our findings show that Jenny's basic face-processing system is perfectly intact. The problem arises because the communication between her visual system and her memory system has become exaggerated. Her brain is essentially sending a powerful signal that she knows a person when it should be silent.'
Coping strategies
Jenny has learned to manage the condition by avoiding direct eye contact and focusing on cues like rings, hair length, or dogs. She trains friends to wear bright clothing or wave so she can identify them in public. At work as a zookeeper at Filey Zoo, colleagues are supportive, and she views her condition as a superpower that helps her deliver talks with confidence.
She said: 'Now I just take one quick glance around and it is as if I am talking to my friends. If you could bottle up my condition, it could cure social anxiety.' Despite the challenges, she remains positive: 'I have learnt to take control and try my best to live as normally as possible.'
