In a new study, researchers have identified a potential treatment for Sandhoff and Tay-Sachs diseases—two rare, often fatal lysosomal storage disorders that cause progressive damage to nerve cells in the brain and spinal cord.
After years of investigating the diseases' underlying mechanisms, the research team has identified an existing FDA-approved drug that could significantly improve quality of life for affected patients and their families.
"Sandhoff and Tay-Sachs are devastating diseases," says Suleiman Igdoura, a professor of biology and pathology who has been researching these conditions for years. "They're marked by progressive loss of motor functions—from sitting, standing, and swallowing to even breathing—as neurons in the nervous system die. Watching someone go through this is heartbreaking."
"Patients often require intensive hospital care as symptoms worsen, and our current treatment options are severely limited," explains Igdoura.
By studying late-onset cases, Igdoura and his team uncovered that these diseases begin in the spinal cord, where chronic stress on a cellular component called the endoplasmic reticulum triggers programmed cell death. Observing the decline in spinal cord neurons in late-onset patients provided crucial insights into how the disease progresses throughout the body.
This breakthrough led to the identification of a potential therapeutic compound: 4-phenylbutyric acid (4-PBA), an FDA-approved drug initially developed for another condition. Testing in a mouse model of the disease showed that 4-PBA significantly improved motor function, extended lifespan, and increased the number of healthy motor neurons.
Igdoura and his team are optimistic that this discovery could be transformative.
Further research is underway to identify the optimal human dosage of 4-PBA.
The insights gained from studying Sandhoff and Tay-Sachs may also have broader implications, potentially informing research into other neurodegenerative diseases such as Alzheimer's and ALS.
"There may be lessons here that apply to a range of neurodegenerative conditions," Igdoura says.

I suspect there is a lot more of this neurodegenerative phenomenon than anybody realizes.
