Spongy Degeneration with Cerebellar Ataxia 2

Brain and Spinal Cord

This is a neurodegenerative condition similar to the human multisystemic SeSAME/EAST syndrome. However, unlike SeSAME/EAST syndrome, affected dogs do not show signs of kidney disease or deafness.

  • Signs and symptoms

    Affected dogs show signs of cerebellar dysfunction at a young age (1 to 2 months old) including a lack of coordination walking, tremors, and poor balance. Seizures can also develop.

    Signs are often first apparent at 1-2 months of age.
