Dog seizure & brain

Brain tumors in dogs are abnormal growths of cells within the brain.

Hydrocephalus in dogs is the condition of too much fluid inside the head, often resulting in pressure on the brain.

Meningitis is an uncommon, potentially life threatening condition that refers to inflammation of the meninges. Meninges are membranes that cover the brain and spinal cord. 

Atlantoaxial instability (AAI) in dogs affects the first two neck bones in the spine: the atlas (vertebra C1) and axis (vertebra C2), which give the head and neck stability. Changes to the bone(s) or ligaments in these joints can cause instability, resulting in dislocation and spinal cord compression. 

Narcolepsy is a sleep disorder affecting the brain characterized by excessive daytime sleepiness and spontaneous or emotion-triggered collapse (cataplexy). This is an uncommon condition in dogs, and can be caused by a genetic predisposition or in rare cases, a brain disorder or nerve disease.

Polyradiculoneuritis (PRN), also known as coonhound paralysis, is a condition in dogs where the immune system attacks the nervous system resulting in inflammation of nerves, primarily in the legs. The cause of most forms of PRN is unknown, but coonhound paralysis is linked to a reaction to raccoon saliva.

Dropped jaw (trigeminal neuropathy) is a disorder of the cranial nerve that controls the movement and sensitivity of the jaw in dogs.  The characteristic symptom is the inability to close the mouth.

Facial nerve paralysis describes the inability of a dog to move the muscles in its face because of a dysfunction in the nerves. This appears as ‘droopiness’ or sagging of the facial muscles, lips, ears, and eyelids.

Canine epilepsy is a disorder where abnormal, uncontrolled electrical activity in the brain causes seizures.

Motion sickness (also known as car sickness) is when a dog shows signs of nausea and/or vomiting as a result of being in motion outside of their control.

Dementia, or Cognitive Dysfunction Syndrome (CDS), is an age-related degenerative disease which affects memory and learning in dogs. Dogs with CDS present with a wide variety of progressive symptoms, including disorientation, anxiety, abnormal interactions, disturbances in  sleep/wake cycle, learning or memory changes, house soiling, and changes in activity levels.
