Details
Alexander disease is a rare neurodegenerative disorder. Symptoms can include: generalized tremor, general stiffness, spasms and increased spinal reflexes. Age of onset is suspected to be juvenile - under 12 months, but can appear very young 6-8 weeks.
Details 2
Affected Labrador retrievers start to show symptoms by 4 to 6 weeks of age. Symptoms include severe tetraplegia, spastic forelimbs, and mild vestibular signs. Histopathological examination reveals numerous intra-astrocytic Rosenthal fibers in the brain and spinal cord with large GFAP accumulation. Due to the severity of the neurological symptoms, affected puppies usually need to be euthanized.
