Batten disease is one of approximately 50 diseases called lysosomal storage disorders (LSD), meaning that genetic mutations disrupt the cells ability to dispose of wastes. With Batten disease, cells are thrown out of balance with the build-up of proteins and lipids (fats).
Because of these damaged cells, patients with Batten disease suffer progressive neurological impairment, which includes:
- Visual impairment/blindness
- Personality and behavior changes
- Loss of motor skills and the ability to walk, talk and communicate
The arc of the disease can vary tremendously for each person.
