Progressive cerebellar abiotrophy (CA) has been described in several different breeds. The disorder is due to loss of neurons in the cortex of the cerebellum.
This disorder causes affected dogs to have difficulty keeping balance and controlling their movements. They become clumsy, have difficulty walking and can have consistent tremors.
The University of Helsinki is currently studying CA in the Lagotto Romagnolo
