I can’t recognise my own children’s faces because of this impossibly cruel condition. There is no cure or treatment and it’s far more common than you’d think: LYNN MARTIN

As the children pour out of school, I start to scan their feet. ‘Look for the shoes with the grey sparkly wings on the side,’ I remind myself silently.

Were I to say this out loud, I suspect I’d get a few odd stares. But I’d chosen my seven-year-old son Titus’s distinctive footwear on purpose. This is the best way, sometimes the only way, that I can distinguish him from his classmates at home time.

As I scan children’s feet, I’m quietly hoping none of the other parents strike up a conversation. I could have met them hundreds of times. But chances are I would have absolutely no idea who they were.

This is the reality of living with prosopagnosia, also known as face blindness. This is a neurological condition where the part of the brain that allows us to recognise those we’ve seen before doesn’t work properly.

It affects around one in 50 people in some form, though this rises to one in 10,000 for cases as severe as mine. While some develop the condition after sustaining brain damage – be it from a stroke or head injury – it most commonly occurs, as in my case, when the ability to recognise faces never develops, which may run in families.

At 45, I have spent my life unable to recognise the people I know, including my own parents, husband and children. So extreme is the condition that if you showed me a photograph of myself, I wouldn’t even recognise my own face.

It’s nothing to do with eyesight or memory – it’s not that I’ve forgotten the people I’ve met, like dementia sufferers – just that my brain can’t process their faces properly.

Sadly, there is no cure or treatment. Sufferers just have to develop coping mechanisms to allow them to recognise people by other means – like my sons’ distinctive shoes: wings for Titus, waves for his brother Valentin, 12.

For those who don’t have the condition, I know it may seem baffling. When I look at a face, I can see the individual features – eyes, nose, hair – but they don’t come together to create a person I recognise. So I’m always desperately looking for clues, like a scar, a mole or a bold pair of glasses or handbag. Once someone starts talking, I can also recognise them from their voice.

However, over the years many people – including friends I’ve known for years but have blanked in the street, or men I’m dating but walk past in restaurants – have called me a liar, unable to believe I simply can’t recognise anyone.

I was five when I first realised I was different. At school, the other children had no problem recognising each other, their parents and our teacher, while for me it was a constant struggle – though then I didn’t have the words to express my confusion. Aged seven I was briefly separated from my dad in the supermarket, before spotting him and going up to chat to him. It was only when my actual dad came over a few minutes later that I realised I’d been speaking to a perfect stranger.

I was too embarrassed to tell my parents the truth, and they assumed I was just particularly social. But as time went on, these incidents brought on waves of shame and fear as I became convinced there was something really wrong with me. Yet still, I felt unable to confide in anyone. As a teenager I coped by constantly jumping between one friendship group to the next, so it seemed more understandable if I sometimes mixed people up.

But it was exhausting. Every time I saw someone, I’d think, ‘Do I know you?’, my brain whirring as I scanned them for anything that would help me identify who they were, while also maintaining a conversation and trying to appear ‘normal’.

Yet inevitably there were times I couldn’t place someone, and would have to ask them who they were, leading to, at best, bemusement and, at worst, outright hostility. Many friends accused me of being two-faced – discussing our most intimate secrets one day and ignoring them the next.

When I did eventually try to explain why, even members of my own family suggested I was making it up, which was devastating.

Then in 2000, when I was 20, I met John, a colleague at my new job in a pet shop.

For most people, physical appearance plays a big part in attraction. But of course for me, that isn’t the case. Instead I’m drawn to how someone treats others. And it was obvious to me what a kind, caring person John was. He was also incredibly observant, immediately seeing that I struggled to recognise people and quietly stepping in to help.

When I’d fail to recognise him, he was totally unfazed. He never suggested I was making it up but accepted me for who I was, and we soon fell in love.

A year after we married in 2002, I was listening to the radio when an interview came on with neurologist Oliver Sacks about his book, The Man Who Mistook His Wife For A Hat. In it he writes about a patient who, following a brain tumour, struggled to recognise faces, including his wife’s. His condition was called prosopagnosia.

It was a lightbulb moment. Realising that I wasn’t alone was incredible. It wasn’t my fault – my brain just wasn’t set up the same way as other people’s. A visit to my doctor later confirmed that I have the condition.

While there is a genetic component to prosopagnosia, no one else in my family has it. However, there is a correlation between conditions such as dyslexia and dyscalculia – both of which concern pattern recognition – and face blindness, and like me my mother is dyslexic.

Becoming pregnant in 2012 brought with it new challenges. The wave of love I felt when I first held Valentin was amazing, and I was sure our bond would overcome my face blindness. So it was a huge emotional struggle to be forced to accept that the second he was out of my sight, I wouldn’t recognise him.

I knew his smell, but if he was across the room with another baby, and I didn’t know which onesie he was wearing, I wouldn’t know which child he was.

I still remember the awful conversation the first time I dropped him at nursery after going back to work and tried to explain to staff why I wouldn’t recognise him when I came to pick him up. I could see them judging me.

My face blindness was the reason we chose the unique name Valentin – and later Titus for our second-born. Having a husband with such a common name was a nightmare; if we were separated in a crowd and I called ‘John’, scores of men would turn around. I didn’t want that with my children.

I first told Valentin about my face blindness when he was five. I wanted to reassure him that if I didn’t recognise him, it wasn’t because he’d done anything wrong. He did his best to help me, but it’s a lot for a small child to understand.

And a further blow was to come. In January 2023, John passed away suddenly at 42. He’d been more than just a wonderful husband and father, but my champion, too. Without him by my side to point out who people were, I wondered how I’d cope, and it has been very hard at times.

It was after John’s death that I started talking about my prosopagnosia on TikTok. Since opening up to my friends about my condition I found our relationships deepened and I wanted to give other people the confidence to speak out, too. The response has been incredible, and it’s been wonderful to help spread awareness.

While my children do their best to accept my condition, I know it’s hard for them sometimes. I suspect they’d love to have a mum who actually recognises her own sons at pick-up time.

I’d love that, too.
