Most people return from a holiday with photos, souvenirs and happy memories. Few imagine that an infection picked up abroad could remain hidden for years before causing serious health problems.
According to PA Real Life, as reported by LADbible, one Welsh woman's experience highlights just how unexpected that journey can be.
A rare diagnosis
Doctors eventually diagnosed Lowri Denman with neurocysticercosis, a rare condition caused when the larvae of the pork tapeworm spread to the brain.
Although the disease is uncommon in countries with modern sanitation, it remains one of the most serious complications of a tapeworm infection.

Brain scans revealed 38 parasites in Denman's brain. The diagnosis came several years after a two-month trip to India in 2007, where doctors believe she most likely contracted the infection.
Ironically, she had chosen to follow a vegetarian diet throughout her travels in an effort to reduce the risk of food-borne illness.
Years of health challenges
Before doctors identified the cause, Denman began suffering from severe headaches followed by epileptic seizures. Treating the infection proved difficult, as the parasites did not respond to medication as quickly as specialists had expected.
The illness gradually affected every aspect of her life. She lost her driving licence because of the risk of seizures, had to leave her job and later required hospital treatment after developing significant mental health problems.

Doctors were unable to determine whether those symptoms resulted directly from the infection, the prolonged treatment or the emotional strain of living with a serious illness for years.
Rebuilding her life
Following years of medical care, Denman's condition slowly improved. Her seizures are now controlled with medication, and she has remained seizure-free for around a decade. She was able to return to work in 2022 after spending much of her thirties focused on recovery.
Health experts say neurocysticercosis can remain undetected for years before symptoms appear, making diagnosis particularly challenging.
While the condition is rare in Europe, Denman's story serves as a reminder that persistent neurological symptoms following international travel should always be thoroughly investigated to ensure timely treatment and the best possible outcome.
