Reports from Canada suggest that two-year Keegan Mclellan may be one of the youngest people ever to be diagnosed with Parkinson’s disease

A two-year-old toddler may be the world’s youngest ever person to be diagnosed with ‘juvenile Parkinson’s disease with dystonia’. In a report by Canada’s CTV claim, Keegan Mclellan’s family say, “his hands shake when he tries to concentrate on tasks and his legs jiggle when he tries to stand still.”

The Mclellan family didn’t know what was wrong, but after travelling across Canada visiting different doctors and trying to find the cause of the problems, Keegan was finally diagnosed.

Keegan’s mother, Cortney Shyla Mclellan, said: “I’ve heard of Parkinson’s, but never in a child.”

Keegan is on medication that helps his symptoms, but his mother is hoping that a trip to the Hospital for Sick Children in Toronto will provide more answers.

The family has been told that keeping Keegan active will also help his symptoms.

“They say if he tries to slow down, it makes his brain work more, so he gets more muscle spasms,” Cortney said. “If he takes off running, it’s easier on him.”

Is the age of diagnosis getting younger?

Eros Bresolin, freelance graphic artist and finalist in the World Parkinson’s Congress 2016 Video Competition, was diagnosed with the condition 10 years ago when he was 34-years-old.

He told magazine This is local London: “The age at which people get diagnosed with Parkinson’s seems to be getting younger and younger all the time.”

Lizzie Graham, director of the European Parkinson’s Disease Association, said: “Unfortunately the full extent of the daily impact on people with Parkinson’s and their families – not to mention the burden of the disease on public health and care systems – is not understood as well as it should be or given the priority needed by policymakers and decision makers.

“Despite this fact, Parkinson’s represents a serious challenge to all people affected by it – particularly so for the numbers of younger people being diagnosed with this progressive, chronic and complex disease. Parkinson’s can affect anyone, and these increasing young-onset instances reinforce our view that more should be done to increase the awareness of Parkinson’s (and related conditions) across all sections of society.”

Parkinson’s isn’t just an ‘old person’s disease’

Meet these ‘young-onset’ patients who experienced Parkinson’s symptoms or were diagnosed early in life.

Matt Eagles – began experiencing symptoms at just 7

“Perhaps my most vivid memory of that time is being chastised by my mum for not being able to stand on one leg when she was cutting my toenails.”

After successful deep brain stimulation surgery in 2006, Matt leads an active life as a sports photographer now that he’s in his early 40s.

Elisa Rovelli – loss of balance started when she was 10

“I was still at primary school in a village of the region called Brianza, in the north of Italy, when I first started feeling weak. I soon lost my balance as my centre of gravity was beginning to shift ahead.”

Having lived with the condition for 20 years she has managed to complete university and found a job in a large bookshop, where she loves her work.

Jordan Webb – Parkinson’s motor symptoms at 17

“My writing was getting smaller, and I seemed to have a slight tremor in my right hand that increased when I was nervous. I also noticed that people were misunderstanding what I was saying.”

Twenty-one-year-old Jordan has now graduated form the University of Manchester with a BSc in psychology. He hopes to continue his studies in neurorehabilitation of movement disorders and traumatic brain injury on a Master’s course.

Shaun Slicker – diagnosed at the age of 23

“I would have to crawl from my living room to my bedroom – I became housebound and put on six stone.”

Now 30, the dad of three’s body is almost completely covered in tattoos and he poses for tattoo magazines, where half of the money he earns goes to Parkinson’s causes.

      sorry but Fluoridated water does not lead to PD.

    Too many poisons in our drinking water and food. We’ve poisoning the developing brains of infants in the womb. Fluoridated water and pesticide drenched foods consumed by the mother has an impact on brain development. Causes misfolding.

    If you develop Parkinson’s and live in France you will be compensated if you were exposed to pesticides. We have dramatically increased this in our food-

    My PWP struggled during his younger years with walking, the doctors just said he was pigeon toed plus in jr high he had difficulties with his penmanship, he was often scolded by teachers as his writing was small and cramped. They just did not know to look for PD in younger children in past times, they thought it was an old persons diseases.

  • Susan

    My late father died at the age 0f 77 years, after battling PD for the better part of ten years. I feel it’s important to note in his case, he may have suffered from Parkinsonian Syndrome. He took various prescribed psychiatric medications in his adult life. One of his specialists attributed his symptoms of shaking, dystonia, mask-like facial expressions as being more likely caused by the older class of meds he had taken than actual Parkinsons Disease. There was no history of the disease in his family. I now have a brother in middle age who to me shows slight signs of PD. He too has a long history of taking psychiatric meds.
