Rare Disease Day: David Cameron Opens Up About What He Learned From Son's Rare Epilepsy Condition

'We were all devoted to Ivan and as a family.'

David Cameron has shared what he has learned as the father of a son who was born with a rare condition to mark Rare Disease Day.

The former Prime Minister, 51, explained how his eldest son, Ivan, was born with what the family later found out to be Ohtahara syndrome, a neurological disorder he said was “so rare that there was barely a diagnosis, let alone a cure”. Ivan died in 2009, when he was six years old. 

Babies with Ohtahara syndrome, a rare epilepsy syndrome, have an underlying structural brain abnormality. This may be genetic in origin (passed on through the genes), or happen because of brain damage before or around the time of birth.

“I will never forget the moment of being told that he was likely to be severely disabled,” Cameron wrote in a piece for The Times. “Sitting in the doctor’s room, trying to understand the immensity of what is being explained to you; all your hopes and dreams about the life your child is going to have and the realisation that it’s not going to be like that.”

Cameron, who is also dad to Florence, seven, Arthur, 12, and Nancy, 14, with his wife Samantha, continued: “It’s a shock and takes a huge amount of time to get over it — but we did. We were all devoted to Ivan and as a family we still talk about him all the time today.

“We were bowled over by the heroic attempts of doctors and nurses to treat and care for Ivan, but we were also reminded of how little we know about conditions such as epilepsy and some of its rare syndromes.”

Cameron went on to say he believes we need to focus on what happens after a person gets a rare disease diagnosis, adding that currently only 5% of rare diseases have approved treatment. He called in “important” and “urgent” to continue to seize scientific developments related to rare diseases.

This isn’t the first time Cameron has opened up about his son Ivan. Interviewed on the Alan Titchmarsh show just a few months after his son died, he revealed that he and Samantha had received around 11,000 letters since their loss.

“We always knew that Ivan would not live forever, and he had been incredibly ill during his short life, but we never expected him to die so young and so suddenly,” he said at the time, according to The Telegraph. “We just miss him. What was very touching was the amount of people who had children like Ivan.

“That was sort of helpful in a way - we sat down and read them together. We’re going through what they have gone through.”

The dad spoke again at length in a candid interview in 2014, venting his frustration at those who told him “some good” could come out of the tragedy.

“Even though Ivan was very disabled and very ill, it was all just a total shock,” he told the Mail on Sunday. “But the person who says to you, ‘There’s a silver lining to all this,’ or ‘Some good will come of all this,’ you actually want to thump.

“It’s the most annoying thing anybody can possibly say.”

21 Rare Diseases
Stiff Person Syndrome(01 of20)
Open Image Modal
People who suffer from this acquired neurological disorder experience repeated, often painful, muscle spasms as well as muscular rigidity and stiffness. According to the National Organization of Rare Diseases, spasms can occur at random or they can be caused by something as seemingly benign as light physical contact or an unexpected noise. The cause of Stiff Person Syndrome isn't yet known, but symptoms can be stabilized with medication. Left untreated, however, a person can lose the ability to walk.
Gigantism(02 of20)
Open Image Modal
This disease, which according to the NIH is most often caused by a begnin tumor in the pituitary gland, results in an excess of GH, or growth hormone. This causes sufferers to grow abnormally large, not just in terms of height, weight but also organ size. It results in complications like delayed puberty, increased sweating, and secretion of breast milk.
Pica(03 of20)
Open Image Modal
Characterized as an eating disorder, Pica causes people to eat what the National Organization for Rare Disorders describes as "non-nutritive" things. That umbrella term can include (but isn't limited to) dirt, clay, paper, and paint. Interestingly, it's not unusual for young kids to experience transient pica as a kind of phase, and pregnant women are also known to develop temporary pica cravings. The cause? Unknown. But in order to be diagnosed with full-blown Pica, a person's symptoms must last for more than a month.
Maple Syrup Urine Disease(04 of20)
Open Image Modal
MSUD, which is passed down through families, is a life-threatening metabolic disorder passed down through families that stems from the body's inability to process certain amino acids, leading to a build-up of them in the body. According to the NIH, symptoms usually surface in early infancy and can include vomiting, lack of energy, seizures, and developmental delays. MSUD takes its name from another symptom -- the urine in affected infants smells like caramel or maple syrup.
Situs Inversus(05 of20)
Open Image Modal
Situs Inversus is a congential condition in which internal organs of stomach and chest lie in mirror image of their normal body position -- something many sufferers aren't aware of until they seek medical help for an unrelated problem. People with Situs Inversus typically wear some form of identification to help doctors in the case of a medical emergency.
Trigger Thumb(06 of20)
Open Image Modal
Trigger thumb, or trigger finger as it's sometimes known, causes a person's finger or thumb to get caught in a locked position. According to the Mayo Clinic, it can then stay stuck or straighten with a painful "snap." The cause? It depends. Trigger Thumb is the result of a narrowing of the sheath around the tendon in the problem figure, but that can be caused by a lot of things, including any activity that requires people to grip things frequently. Trigger Thumb is also more frequent in women.
Scurvy(07 of20)

Once the disease of sailors and pirates, scurvy does still exist in the United States, though predominantly in older, malnourished adults. It usually stems from a Vitamin C deficiency, which can result in gum disease, skin leisons, and swelling of the joints. (credit:Getty )
Wilson's Disease(08 of20)
Open Image Modal
This progressive genetic disorder causes sufferers to store excess copper in tissues, including the brain and liver. Though the Mayo Clinic says that the body depends on copper in order to use iron and sugar, too much of it in the body can have real consequences. Which is why sufferers of Wilson's Disease are prone to liver failure.
Foreign Accent Syndrome(09 of20)
Open Image Modal
According to researchers at the University of Texas at Dallas, this speech disorder causes people to experience a sudden shift in their accents and though it is known to be caused by things like brain trauma, conversion disorder, or multiple sclerosis, an exact reason behind the syndrome is unknown. Sufferers of FAS dramatically shift their speech in terms of timing and intonation, which often causes them to sound foreign, but they remain totally comprehensible. Documented accent shifts include from American English to British and from British to French.
Carcinoid Syndrome(10 of20)
Open Image Modal
According to the National Organization of Rare Diseases, about 10 percent of people with carcinoid tumors -- which the Mayo Clinic says are slow growing tumors that produce excess serotonin and usually appear in the gastrointestinal tract or lungs -- get this syndrome. It occurs only in patients whose tumors have metastasized to the liver. The symptoms? Wheezing, hotness, and extreme facial blushing.
Cyclic Vomiting Syndrome(11 of20)
Open Image Modal
Children and adults afflicted with CVS experience recurrent episodes of severe vomiting, which can last for days, followed by sudden periods of no vomiting. While kids are likely to experience more frequent attacks, adults's often last longer. To date, the cause of CVS is unknown.
Peeling Skin Syndrome(12 of20)
Open Image Modal
This obscure, genetic skin disorder does exactly what its name implies: causes sufferers to experience constant shedding of their skin. (In some patients, peeling is limited to the feet and hands.) Along with that, sufferers often feel itching and redness -- symptoms that can appear from birth or develop later in life. Although the exact cause is unknown, a mutation in the TGM5 gene has been identified in many sufferers.
Platelet Storage Pool Deficiency(13 of20)
Open Image Modal
This is a blanket designation for several rare platelet abnormalities, most of which lead to mild or moderate bleeding disorders. According to the NIH, the problem stems having limited granules -- the parts of platelets that, among other things, store ADP -- the energy released when a molecular bond is broken. That reduction in storage space inhibits the platelets' ability to secrete ADP in a speedy fashion, which is thought to be what causes the bleeding. Classic symptoms of a Platelet Storage Pool Deficiency are nosebleeds, excessive bruising, and profuse bleeding in surgery.·
ACDC(14 of20)
Open Image Modal
Only nine people in the United States are known to have this disease, which was just given a name in a recent study in the New England Journal of Medicine. ACDC, or arterial calcification due to CD73 deficiency, results in calcium build-ups in the arteries below the waist of sufferers and in the joints of their hands and feet. According to the NIH, the breakthrough discovery found that the disease is related to a variant in the NT5E gene.3
Conversion Disorder(15 of20)
Open Image Modal
This condition, which typically occurs after an extremely stressful emotional event, causes a person to experience sudden blindness or paralysis that can't be otherwise explained. People with mental illlnesses are at particularly high risk and psychological treatment can help lessen the symptoms.·
Ochronosis(16 of20)
Open Image Modal
Ochronosis results in black or blue external tissues, often the ear cartilage or eye, though it can occur throughout the body. It affects people who suffer from certain metabolic disorders, but it can also be caused by exposure, though scientists aren't exactly sure to what. Not just a cosmetic issue, the affected areas can become brittle and degenerate over time.
VLCAD Deficiency(17 of20)
Open Image Modal
This condition, which is caused by genetic mutations in the so-called ACADVL gene, keeps people from converting certain fats to energy. According to the NIH, the deficiency often presents during infancy in symptoms including low blood sugar, weakness, and lethargy.
Hairy Tongue(18 of20)
Open Image Modal
As the name suggests, Hairy Tongue is a condition in which the tongue develops a black, hairy texture. According to the Mayo Clinic, the disease is "harmless" and is caused by an overgrowth of bacteria in the mouth, which can be treated with antibiotics. The NIH reports that hairy Tongue can also present as brown, yellow, or green discoloration. ·
Ochoa (Urofacial) Syndrome, or, Peculiar Facial Expression(19 of20)
Open Image Modal
This obscure, inherited disorder presents at birth and causes infants to grimace when, in fact, they are attempting to smile. The disorder also includes an extreme urinary abnormality: an obstruction that interrupts the connection between nerve signals in the spinal cord and bladder, leading to incontinence. Though treatment does exist in the form of antibiotics and bladder re-education, some patients can develop renal failure in their teens and 20's, which can be life-threatening.
Progeria(20 of20)
Open Image Modal
According to the Mayo Clinic, only around 130 cases of this devastating genetic disorder have been documented since it was discovered in 1886. Affected babies normally appear normal at birth, but within 12 months begin to have symptoms like hair loss and wrinkles. According to the Mayo Clinic, progeria is caused by a genetic mutation, but not one that's passed down through families; it's a chance event that affects only one egg or sperm. The average life expectancy for sufferers is 13.
