Chiari-like malformation (CM) the most common cause of foramen magnum obstruction and syringomyelia in dogs. Syringomyelia (SM) is a disease of the spinal cord typified by fluid filled cavities, or syrinxes, within the spinal cord substance but it can cause pain by disrupting the cerebrospinal fluid (CSF), in the brain [1] CM is a condition characterized by the mismatch of size between the ...
Cognitive dysfunction syndrome in dogs is an established diagnosis, but there has been limited research for cats and treatment options are limited. [13] Drugs used for treatment of the disease have been approved for use in dogs. However, they are used off-label in treatment of cats. [1] Early diagnosis improves results of long-term treatment.

Domestic cat showing signs of aggression: Symptoms: Frantic scratching, biting or grooming of tail and lower back; aggression towards other animals, humans and itself; and a rippling or rolling of the dorsal lumbar skin. Usual onset: Around 9–12 months, or when the cat reaches maturity. Duration
Radionuclide cisternography may be used to diagnose a spinal cerebrospinal fluid leak. CSF pressure is measured and imaged over 24 hours. [2] A radionuclide (radioisotope) is injected by lumbar puncture (spinal tap) into the cerebral spinal fluid to determine if there is abnormal CSF flow within the brain and spinal canal which can be altered by hydrocephalus, Arnold–Chiari malformation ...
Affected cats may also display poor judgement of distance, and some cats may develop a rapid, crouching, hypermetric gait. Some affected cats may exhibit an abnormal head tilt, tremors, a vacant stare, excessive salivation, decreased grooming behaviors, polyphagia , and dilated pupils. [ 3 ]
Cerebrospinal fluid (CSF) is a clear, colorless transcellular body fluid found within the meningeal tissue that surrounds the vertebrate brain and spinal cord, and in the ventricles of the brain. CSF is mostly produced by specialized ependymal cells in the choroid plexuses of the ventricles of the brain, and absorbed in the arachnoid granulations .
Intracranial pressure (ICP) is the pressure exerted by fluids such as cerebrospinal fluid (CSF) inside the skull and on the brain tissue. ICP is measured in millimeters of mercury and at rest, is normally 7–15 mmHg for a supine adult. This equals to 9–20 cmH 2 O, which is a common scale used in lumbar punctures. [1]
The CSF tap test, sometimes lumbar tap test or Miller Fisher Test, is a medical test that is used to decide whether shunting of cerebrospinal fluid (CSF) would be helpful in a patient with suspected normal pressure hydrocephalus (NPH).
