Lowri Denman, a 42-year-old Cardiff woman, discovered she had 38 brain parasites after contracting a tapeworm during a 2007 trip to India, according to reports from multiple outlets. The infection, which led to seizures, psychosis, and long-term health struggles, highlights the risks of parasitic diseases in travelers.
The Parasitic Discovery and Initial Symptoms
Denman first noticed the tapeworm in 2010, passing a metre-long specimen in a restaurant toilet. She described it as “absolutely disgusting, like Sellotape with like little ridges in it,” according to gbnews.com. At the time, she had no symptoms and dismissed it as a one-off incident. However, four years after her trip, she began experiencing “really bad headaches,” which escalated into a 2011 seizure that led to her diagnosis with neurocysticercosis, a brain infection caused by pork tapeworm larvae.

"The World Health Organisation notes that tapeworms can be contracted through contaminated water or poor hygiene," he explained. "Even with precautions, the risk remains."
The Diagnosis and Medical Response
After her 2011 seizure, Denman underwent brain scans that revealed 38 parasites in her brain. “The doctor sat me down and said: ‘Right, okay, we’ve looked at your scans and we’ve found 38 parasites on your brain,'” she recalled, as reported by walesonline.co.uk. Initial treatments included steroids and albendazole, an anti-parasitic drug, but her condition fluctuated. She experienced recurring seizures, anxiety, and paranoia, which led to a six-week stay in a neuropsychiatric facility.

“This paranoia and psychosis started kicking in there was severe anxiety, panic attacks,” Denman said, per gbnews.com. Her friend Nicola Brown described a harrowing encounter where Denman “was essentially behaving like a child,” crawling on the floor and hiding behind curtains. The ordeal forced Denman to move in with her father and abandon her career.
The Long-Term Impact and Recovery
Despite periods of stability, Denman’s health remained unpredictable. She spent two weeks in hospital after collapsing at work, with scans showing brain swelling linked to the parasites. “At that point there’s so many questions because you just don’t know what’s ahead of you with your health,” she said, as cited by bbc.co.uk. The uncertainty included concerns about medication, work, and her future.
Denman’s recovery was marked by resilience. She completed an art foundation course and gradually regained strength, though her life was forever altered. “What I want to do now is progress in my life and spread awareness of this disease and do something positive with it,” she told walesonline.co.uk.
Public Health Implications and Awareness
Neurocysticercosis is rare in the UK, with only a handful of cases reported annually. The disease underscores the importance of hygiene and food safety, particularly in regions where tapeworms are endemic. "Contaminated water and undercooked meat remain key vectors."

Denman’s case has sparked discussions about the long-term effects of parasitic infections. While treatments can manage symptoms, the psychological and social toll—such as loss of independence and strained relationships—remains underexplored. “Her story is a reminder of the hidden dangers of travel and the need for better public health education,” said a public health official, per walesonline.co.uk.
As Denman continues her journey, her experience highlights the intersection of personal resilience and global health challenges. For travelers, her story serves as both a cautionary tale and a call to prioritize health awareness in unfamiliar environments.
“The panic of what’s next, what am I going to have to deal with, what medication am I going to go on, can I go back to work?” she asked, reflecting on the ongoing uncertainty. “It’s a constant battle, but I’m determined to move forward.”
