What it is
Neuronal Ceroid Lipofuscinosis 4A (NCL-A) is an inherited metabolic disorder that affects the nervous system, particularly the brain. It occurs when a genetic mutation prevents cells from breaking down cellular waste products called lipofuscins, leading to a harmful buildup of these fatty pigments. Over time, this accumulation causes progressive damage and destruction of brain cells.
How it presents
Owners typically first notice symptoms like clumsiness, loss of balance, and a stiff gait between 3 and 5 years of age. These coordination problems gradually worsen over time, leading to severe difficulty walking.
Treatment
There is no cure for this condition, and care is focused entirely on managing symptoms to maintain comfort. Palliative and supportive care over the dog's remaining life typically costs between 1,000 and 3,500 EUR.
