Symptoms include slow movement, stiffness, and loss of balance. Parkinson's can affect young dogs or pups. Symptoms include tremors, stiff muscles or movement, and difficulty with balancing and walking. Symptoms include amnesia, anxiety, depression, headache, sleepiness, staring spells, or temporary paralysis after a seizure.Ĭaused by a loss of a neurotransmitter, dopamine, in nerve cells. It has varied causes and is common in many dogs.

This is an inherited condition that manifests as constant seizures. Muscle wasting (shrinking and weakness) in the legs. Muscle weakness (especially in the feet and legs). Inherited polyneuropathy has a genetic component. Do note that if your pet is being medicated for cancer, polyneuropathy may be a side effect of the medication. The degeneration of myeline can result in spatial nerve disorders (inability to negotiate space), sensory nerve disorders (weakness or paralysis), and a malfunctioning thyroid gland. Signals in the nerves are lost, impeding function, and causing a lack of orientation and improper motor coordination. Myeline, a fatty liquid that acts as an insulator, is lost through a process called demyelination. This term covers a group of disorders that affect the nerves in any combination. Your pet may will not be able to walk properly-exhibiting incoordination, balancing problems, and an abnormal gait. Occasionally, other cells in the brain are affected as well. The cerebellum controls movement, and when functioning normally in puppyhood, specific cells known as the Purkinje cells, deteriorate after birth. He or she may be easily fatigued.ĭeterioration of the cerebellum or the brain causes premature aging. Once this happens, the adjacent muscles cannot be controlled.Ī dog may experience muscular weakness of the eyes, face, and esophagus. The body’s immune system turns on itself, attacking junctions where neurons and muscles interconnect. Acquired myasthenia gravis interrupts communication between the nerves and muscles.
