Batten disease is a genetic, progressive neurodegenerative disorder that typically begins in childhood and is fatal. It is inherited (often autosomal recessive) and involves the buildup of harmful substances in neurons, leading to a cascade of problems: vision loss, seizures, cognitive decline, and motor difficulties as the disease advances. Because the condition stems from genetic mutations and affects the nervous system as a whole, the vision changes occur within a broader decline rather than as a simple eye problem.

This description fits Batten disease while the other statements don’t: it isn’t contagious or self-resolving, it isn’t a mild vision issue with no neurological impact, and it isn’t caused by a vitamin deficiency. In a vision impairment context, it’s important to emphasize that vision loss is part of widespread neurodegeneration, not the sole or primary condition.
