Degenerative Encephalopathy (DEN)
Degenerative Encephalopathy with Sleep Disorders and Caudate Necrosis or simply Degenerative Encephalopathy (DEN) is a neurological condition that affects the nervous system and leads to progressive degeneration or complete destruction of neurons in the brain, specifically in the region of the brain that is important in controlling movement and some aspects of behaviour.
This neurodegenerative disease has an autosomal recessive inheritance and is observed in the Nova Scotia Duck Tolling Retriever (NSDTR, Toller).
