I'm a dementia professor, but the solution to my brain fog surprised me

I'm a dementia professor, but the solution to my brain fog surprised me

Telegraph4 days ago
Aimee Spector, 50, is professor of clinical psychology of ageing and director of the Menopause Mind Lab at University College London (UCL). She has two children of 18 and 20 and lives with her husband, Nick, 52, in Hertfordshire.
I'd always prided myself on being a 'names person'. My job as a professor at University College London involves chairing meetings, introducing people, giving lectures and leading teams – I'd remember everyone. But in 2017, aged 42, that changed quite suddenly.
I'd recently taken a new consultancy role and was being shown around. Just as I went to introduce a very senior colleague, someone I'd worked with for 15 years and talked to daily, his name just… vanished. Gone. Awkwardly, feeling my face redden, I ended up helplessly pointing at the name on his door. I went home confused, shocked and frightened about what was happening.
More mortifying still was only last month, when I was working with the World Health Organisation updating dementia guidelines. During a high-level meeting about HRT and dementia risk, I forgot the word 'oestrogen'. I paused, tried to joke, 'it's my morning brain fog ' and people smiled sympathetically, but I felt paranoid they thought I was losing it.
A scary black fog had overtaken me
After that first time forgetting my colleague's name and dreading it happening again, I'd walk into meetings feeling panicked about forgetting names, which of course made it even more likely to happen.
It wasn't just at work. At home I'd ask my children – then both in their early teens – questions about a party for example. They'd eye-roll, 'Mum, you just asked that and we told you already.'
I'd watch a film with my husband, Nick, and have no recollection the next morning. I don't mean I couldn't recall the name of the movie, I couldn't remember the entire storyline, or even the genre. It was like a scary black fog had erased my memories. Another time I drove off with my handbag still on top of the car, scattering its contents over the road.
My fear of dementia was real – and informed
Until then, I'd been a successful psychologist specialising in dementia research, developing cognitive stimulation therapy, to help people with dementia improve their memory and thinking skills, which is now used across the NHS and in 42 countries worldwide.
As my career had been dedicated to studying dementia, my memory loss took on a sinister edge. In my early 40s, mine was now failing me and fearing I had early-onset dementia felt like my whole world unravelling.
I told my GP about these frightening memory blanks. She reassured me it probably wasn't dementia, because I was still able to work with numbers efficiently (essential as a scientist) and neither did I get lost in familiar places, or struggle recognising familiar objects. I had no problem dressing or feeding myself or parenting my teens. I never forgot faces. It was just that my ability to recall stories and my verbal skills seemed to be replaced with blackness.
The GP never suggested menopause as a possibility, and because I still had regular periods and no hot flushes, it never crossed my mind, either.
Back then, brain fog wasn't discussed as a menopause symptom. She and I agreed to keep an eye on it and over the next two years we spoke several times. Blessedly, my symptoms didn't worsen, which would not have been the case with a disease.
Talking myself out of a career
I spoke to my husband, parents and close friends about my fears. 'Don't worry,' they said. 'You're still functioning at a high level at work – no one else notices.' Classically, with early-stage dementia it's not just the person suffering symptoms who realises it, it's other people who notice it.
'You're fine,' everyone reassured. But inside, I seriously considered quietly leaving my job. I'd tell myself: 'You've had a good career, made a difference. Maybe it's time to slip away before everyone notices you're losing it.'
Brain fog destroyed my confidence, my sense of competence and my identity. I've since learnt that around one in 10 women in menopause quit work because they feel embarrassed about their abilities. Even more step back from important meetings (the kind necessary to further careers) or they reduce hours or pass up promotions. Careers women have grafted for, over decades, go up in smoke. It's frustrating to witness yet completely understandable – I was nearly one of them.
Finding the real cause
It wasn't until 2021, at the age of 47, nearly five years after my first symptoms, when a friend asked me 'could it be hormonal?'. So I paid to see a private menopause specialist. Hormonal blood tests are notoriously unreliable, yet mine indeed showed rock-bottom oestrogen levels, far lower than expected at any point in the menstrual cycle.
My progesterone and testosterone were also low and the specialist put me on HRT: oestrogen gel combined with progesterone tablets. Within six weeks, it was as if someone had flicked a light switch in my brain. My memory returned, as did my confidence. Finally I had confirmation my brain fog was hormonal, not degenerative like Alzheimer's.
When my health took a step back
But just nine months later I had to give it up when, in 2022, I was diagnosed with stage one breast cancer. I'd found a lump and it was caught early so I needed surgery but no chemotherapy. I didn't blame HRT, I hadn't been on it long enough, and had a strong family history of breast cancer.
However, because my cancer was hormone-receptive (meaning oestrogen was feeding the cancer cells) I had to immediately stop using it. That devastated me as much as the diagnosis itself, as I dreaded the return of brain fog.
But interestingly, it didn't come back as badly as before, and I believe that's because now I understood it wasn't dementia – that fear had gone and it was easier to manage.
Why perimenopause can cause brain fog
I wanted to investigate why perimenopause causes these cognitive changes – and what can be done. Especially for women who don't want, or can't take, HRT.
I found it helpful to acknowledge what was happening in my brain, understanding that my drop in oestrogen was likely to be affecting the neurotransmitters which affected memory and words. It's this fluctuation of hormones during perimenopause when things like brain fog, or hot flushes or poor sleep, are triggered. The good news is that once the hormones re-stabilise post-menopause, these symptoms go away.
Putting my experience to good use
After what happened to me I wanted to see what the research said, and discovered there was little out there. That had to change. I wanted other women to feel more supported. So in 2023, alongside my work in dementia, I established UCL's Menopause Mind Lab, a research hub focusing on the impact of menopause on cognition and mental health.
I'm proud of what we've achieved so far. But there is more to do. Campaign group Menopause Mandate's survey last year (of nearly 20,000 people) identified brain fog as the single most troubling and prevalent symptom for 76 per cent of women – not hot flushes, which surprised many.
That's why we're joining forces for this year's survey; we're determined to find better treatments. This is why this year we want more women – 30,000 – to take part, from as many different backgrounds and ethnicities as possible, including those with no symptoms at all: it's all helpful. These results will inform academic research on menopause and brain health and power lobbying efforts for better workplace policies. We will present our findings to MPs later this year.
Currently at UCL we're developing a non-drug-based treatment including attention training, cognitive strategies and CBT (cognitive behaviour therapy) to support women who cannot take HRT.
The strategies I use to help me
At 50 now, I still have regular periods, and I still forget words, but I no longer spiral into panic now I've developed strategies to cope (see below).
I want other women to know they're not losing their mind. Brain fog is a manageable symptom of menopause transition. With understanding, support and the right strategies, we can continue to thrive at work and at home. I almost gave up on myself – and I'm so glad I didn't. Please don't lose hope.

What is chikungunya? Symptoms and travel advice as cases rise in France

Health authorities are warning travellers of a mosquito-borne virus that can cause debilitating joint pain, after cases emerged in areas of France. While the virus known as chikungunya is more commonly found in tropical areas of the world, cases have now appeared in France, a popular holiday destination for Brits, especially during the summer months. The World Health Organisation has now raised its concern about the virus, giving new guidelines to healthcare providers on how to help those who have contracted chikungunya. Diana Rojas Alvarez, a medical officer at the WHO, told reporters in Geneva that an estimated 5.6 billion people live in areas across 119 countries at risk from the virus. This year so far, France has reported 30 cases of chikungunya virus on the mainland and the French island of Corsica. Italy has reported one. While Europe is not currently experiencing a severe outbreak, health officials on the continent are making travellers aware of the virus as well as the rollout of a new vaccine in the UK. We have rounded up what travellers need to know about the virus, plus advice from a specialist travel doctor on how to best prepare for travelling overseas. What is chikungunya and how is it spread? Chikungunya virus disease is a mosquito-borne disease that is found across tropical and sub-tropical regions. It is spread to humans by a bite from an infected mosquito. It cannot be passed from human to human. Most cases have been found in the Americas, Africa and Asia. Brazil has the most cases, with over 141,000, followed by Argentina with over 2,500 so far in 2025. In total, there have been approximately 220,000 chikungunya cases and 80 related deaths across 14 countries/territories since the beginning of the year. La Réunion and Mayotte, two French islands off the east coast of Africa, have ongoing outbreaks of chikungunya, with the former recording 51,000 cases as of May 2025. The transmission of dengue and chikungunya virus in mainland Europe has been linked by the European Centre for Disease Prevention and Control (ECDC) to travellers who have caught the virus outside the region, then gone to countries within Europe with mosquitoes that are able to carry the virus after biting the person. 'The risk of locally acquired chikungunya and dengue virus transmissions is therefore increasing,' the ECDC said. What are the symptoms? 'Chikungunya' comes from a word used by the Makonde people in Tanzania, where the disease was first discovered in the 1950s, which means 'that which bends up'. This describes the contorted posture of infected people who experience severe joint pain. Alongside joint pain, people can also experience an abrupt onset of fever, joint swelling, muscle pain, headaches, nausea, fatigue and rashes. The joint pain can be debilitating and usually lasts for a few days, but it has been known to last for weeks, months or even years. If an infected person does not experience joint pain, the symptoms will be mild and can go unrecognised as chikungunya. Most people will recover fully from the infection. There have been some occasional cases of eye, heart, and neurological complications, while newborns and older people with underlying medical conditions are at a higher risk of severe disease. Patients with severe disease should be hospitalised because of the risk of organ damage or death. Once someone has recovered from chikungunya, they are likely to be immune to future chikungunya infections. Is there a vaccine? The UK government has approved vaccines against chikungunya disease, containing a form of the virus that has been weakened so it cannot multiply. The vaccine works by training the immune system to recognise the virus, which will then produce specific antibodies to attack it. It can only be obtained via a prescription and given to those who plan to travel abroad where the virus is present. Last month, the government released a further announcement to say that the Commission on Human Medicines has temporarily restricted the use of the vaccine in people aged 65 and over as a precautionary measure. To prevent getting bitten by mosquitoes, the World Health Organisation advises using insecticides; wearing clothing that minimises skin exposure; using window and door screens, and insecticide-treated mosquito nets; and applying certain repellants to skin and clothing. A travel doctor's guide on being prepared Dr Richard Dawood, a travel medical specialist at Fleet Street Clinic, explained to The Independent how the vaccination can help travellers prevent getting sick from the chikungunya virus. He said: 'This is a new situation for us. Until a very short time ago, we had no vaccine, and the only approach to prevention was to make careful use of insect repellents and insect precautions. 'So now we've got this extra tool in the armoury, and because the vaccine gives long-lasting protection, it's something that could be considered if you are planning to travel over a period of time. 'It's a fairly expensive vaccine, but if you're going to be travelling over a period of years to Southern Europe and beyond, it may be something that could be considered.' When asked about getting the vaccination for a trip to France, Mr Dawood advised to look at the decision in terms of where you will be travelling over the next few years rather than in the context of a single trip. 'The risk from a one-off short trip to France is probably very small,' he said. 'There's been only a very small number of cases so far. So statistically, you're not very likely to, but over time, as somebody who loves to travel and loves going to hot countries, then I would probably want to be protected against it in the long term.' Wherever you are travelling, Mr Dawood advised holidaymakers to 'do your homework'. He said: 'If there's an actual outbreak at your destination, then I would say no hesitation, definitely have the vaccine. 'Taking a bit of time and getting some really focused travel health advice for your particular trip is very worthwhile because it can save you from getting a vaccine that you don't need or that may not be sensible for you, and it can help prioritise the really important things for your trip.

Hospitals in Syria's Sweida struggling after sectarian clashes, WHO says

GENEVA, July 25 (Reuters) - The main hospital in the southern Syrian city of Sweida is overwhelmed with trauma patients and working without adequate power or water after the local Druze minority clashed almost two weeks ago with Bedouin and government forces. "Inside of Sweida, it's a grim picture, with the health facilities under immense strain," the World Health Organization's Christina Bethke told reporters in Geneva via video link from Damascus. "Electricity and water are cut off, and essential medicine supplies are running out." Many medical staff cannot reach their workplace safely, and the main hospital's morgue was full at one point this week as it dealt with a surge of trauma cases. At least 903 people were killed in the sectarian bloodshed, according to the Syrian Network for Human Rights, after clashes between Druze militias and Bedouin tribes spilled into ferocious fighting between the Druze and government forces sent to quell the unrest. The Network's head, Fadel Abdulghany, has said the toll is not final, and that his group documented field executions by Syrian troops, Bedouin tribal fighters and Druze factions. Though the WHO has managed to deliver two convoys of aid in the last week, access remains difficult because tensions remain between the groups controlling various parts of Sweida governorate, it said. More than 145,000 people have been displaced by the recent fighting, the WHO said, with many sheltering in makeshift reception centres in Daraa and Damascus.

Poor regulation causing hundreds of deaths from contaminated medicines globally, says WHO report

Weak regulation has allowed children's medicines like cough syrup and paracetamol to be laced with toxic industrial chemicals leading to hundreds of deaths, according to a report by the World Health Organization. Since 2022, at least 300 people – mainly children in Africa and Asia – have died from cough and paracetamol syrups containing diethylene glycol (DEG) and ethylene glycol (EG): industrial chemicals that are used to make products like brake fluid and antifreeze. The chemicals – a cheap replacement for medicinal glycol – are toxic in even small amounts and cause acute kidney damage that often proves fatal. The WHO report, released jointly with the United Nations Office on Drugs and Crime, said 'criminal networks' were exploiting 'market volatility and regulatory gaps' to introduce these and other toxins into the supply chain in order to make quick profits. 'Most of the recent cases involve inexpensive oral liquid medicines that can be bought without a prescription,' said the report. 'In most cases these medicines were marketed specifically for children and are … available in pharmacies, medicine stores or informal street markets.' In 2022, more than 150 children died in Indonesia from consuming locally produced cough syrups that had been laced with EG. The manufacturer had marked 60,000 bottles of the lethal medication with fake labels showing only safe ingredients, the report said. In the same year, at least 66 children, mostly under the age of two, died in the Gambia from acute kidney failure after consuming cough syrup containing DEG and EG, imported from India. The medicines were produced by the Indian manufacturer, Maiden Pharmaceuticals, which was later discovered to have breached numerous regulations. Two of the owners of the company received prison sentences, the report said. Over the last three years, at least five batches of lethal cough syrups have been traced back to Indian manufacturers from countries including Uzbekistan, Cameroon, and Iraq. Some were found to contain over 20 times the safe level of EG . Each contaminated medicine was produced by a different manufacturer, raising questions about the regulation of India's pharmaceutical industry. Overall, the World Health Organization said at least 1,300 people have died as a direct cause of ingesting contaminated medicines over the last 90 years, and thousands more have suffered 'life changing injuries' – mostly in the developing world. 'In many cases, contaminated medicines are the result of intentional criminal conduct. Addressing this threat requires coordinated efforts by ... law enforcement agencies, customs officials, prosecutors and anti-corruption bodies,' the report said.
