Big Brother star Jon Tickle diagnosed with MND

Big Brother star Jon Tickle has been diagnosed with Motor Neurone Disease (MND), a life-limiting degenerative condition, as his series four co-stars held an emotional reunion in London.

Reunion tinged with sadness

Tickle first appeared on the fourth series of the reality show 23 years ago and was ejected on day 29. He later returned to the house after being chosen by the public to come back, a first for the then Channel 4 show.

Last night, Tickle and other series four housemates gathered in London, with co-star Ray Shah sharing pictures of the get-together. After the link-up, Shah revealed the occasion was tinged with sadness due to Tickle's diagnosis.

Shah wrote: "It has taken us 23 years but we finally got to have a big brother reunion with most of the gang."

He added: "For those that don't know, we were Big Brother 4…one of the OG's. What a great laugh we had meeting up last night in London."

Co-stars share heartfelt messages

Shah continued: "There's a touch of sadness to it though as Jon Tickle was diagnosed with Motor Neurone Disease a few months ago but fair play to Sissy, she helped get us all together."

He added: "Planning the next meet up already and we will get EVERYONE back this time. Until the next time legends."

The reunion pictures have been shared on social media as fans reminisced about how time has flown since the fourth series. Co-star Justine Sellman commented: "Omg it was such a magical night seeing everyone again! Big hugs and love to our very special friends group xxx."

A fan added: "This is so nice bet some laughs were had and god how life moves so quick I watch all big brothers but those first few years were the best."

What is Motor Neurone Disease?

Motor neurone disease is a condition that causes muscle weakness which gets worse over a few months or years. It is usually life-shortening and there is currently no cure, but treatment can help manage the symptoms.

The NHS states: "Motor neurone disease (MND) affects nerves in your brain and spinal cord called motor neurones. Motor neurones tell your muscles what to do."

In those with MND, motor neurones stop working properly, as it is thought to be caused by a combination of certain genes and other factors, though it is not completely clear why this happens.

The NHS added: "About 1 in 10 people with MND have a family history of the condition. But if someone in your family has MND it does not necessarily mean you will also get it."
