Batten disease, or Neuronal Ceroid Lipofuscinosis (NCL), is a group of rare, fatal, genetic disorders causing progressive neurological decline, leading to vision loss, seizures, cognitive impairment, and loss of motor skills, often starting in childhood and resulting in early death. It's a lysosomal storage disorder where cells can't remove waste, causing harmful buildup (ceroid lipofuscin) in brain cells, leading to neuron death and dementia. There are multiple types (CLN1, CLN2, etc.), classified by the affected gene, with varying onset ages, but all are progressive and fatal.
The life expectancy of a child born with Batten disease can vary, depending on the form of the disease and the age of onset. Some children die in early childhood, while others may be able to live into their teens or twenties. Worldwide, roughly 14,000 children are known to have Batten disease.
What medications treat Batten disease? Currently, there's one FDA-approved treatment for children with CLN2. Children receive infusions of a medicine called cerliponase alfa (Brineura®) every two weeks. Providers inject the medicine directly into the fluid surrounding your child's brain.
It's incredibly rare and according to the Batten Disease Support and Research Association about 35 children have some form of Batten disease in Australia — eight of which have CLN2.
The buildup of those substances can induce symptoms such as seizures, vision loss, motor (movement) problems, and cognitive (thinking and reasoning) problems. Batten disease is also often referred to as neuronal ceroid lipofuscinosis or NCL.
Five significant signs your brain might be in trouble include memory loss (especially recent events), difficulty with familiar tasks or language, confusion about time/place, significant personality/behavior changes, and problems with judgment, focus, or coordinating movement, often indicating conditions like dementia, brain injury, or other neurological issues, requiring a doctor's visit.
What are common genetic disorders? Down syndrome (Trisomy 21). Fragile X syndrome. Klinefelter syndrome.
Dementia has overtaken heart disease as the leading cause of death across Australia, according to the Australian Bureau of Statistics (ABS). There were more than 17,500 deaths from dementia, including Alzheimer's disease, in 2024 — making it the cause of 9.4 per cent of deaths nationwide.
Use the three C's campaign (Calm, Cushion, Call) to ensure everyone knows what to do if they see someone having a seizure. Stay CALM and stay with the person who is having a seizure. CUSHION their head with a coat or cardigan to stop them from injuring themselves.
Adults of any age can get motor neurone disease (MND), but it usually affects people over the age of 50. Symptoms you may have at first include: stiff or weak hands – you may have problems holding or gripping things.
Cystic fibrosis (CF) is the most common fatal genetic disease in the United States today. It causes the body to produce a thick, sticky mucus that clogs the lungs, leading to infection, and blocks the pancreas, stopping digestive enzymes from reaching the intestines where they are required to digest food.
Over time, affected children suffer mental impairment, worsening seizures, and progressive loss of sight and motor skills. Eventually, children with Juvenile Batten Disease become blind, bedridden, and unable to communicate. Juvenile Batten Disease is always fatal by the late teens or twenties.
Epilepsy is a chronic brain disorder in which groups of nerve cells, or neurons, in the brain sometimes send the wrong signals and cause seizures.
Tragically, the disease is fatal. There are some treatments which can help with some of the symptoms of juvenile Batten disease, such as seizures. But there is no treatment that can slow the progression of the disease, which is caused by problems with a specific gene and is an inherited neurodegenerative condition.
Neurodegenerative disorders gradually damage nerve cells, leading to problems with movement, memory, or behavior. Common symptoms include memory loss, tremors, difficulty walking, mood changes, and personality shifts.
Batten Disease and Gene Therapy
Gene therapy delivers a functional version of the faulty gene into cells, giving it instructions to produce the proteins needed to restore lysosomal function. To deliver this working gene, a vector is used, which is like an envelope carrying a message.
Status epilepticus can happen with any type of seizure, but convulsive (tonic-clonic) status epilepticus is the most dangerous. Convulsive status epilepticus is when a tonic-clonic seizure lasts for five minutes or longer, or when one tonic-clonic seizure follows another without regaining consciousness in between.
When administering seizure first aid, follow the three S's: Stay, Safe, Side. The procedure remains the same when helping people of any age who are experiencing a seizure.
Possible seizure triggers include:
Dementia is one of the most feared conditions among Australian health service consumers, second only to cancer.
Medical conditions that still remain incurable
Most deaths in Australia, like other developed countries, occur among older people (Figure 2.1). Sixty-eight per cent of deaths registered in Australia in 2023 were among people aged 75 or over (63% for males and 74% for females). The median age at death was 79.6 years for males and 84.6 years for females (Table S2.
