Cats can have reactive, primary or secondary seizures. Idiopathic seizures are not as common in cats as in dogs; however, a 2008 study conducted showed that of 91 feline seizures, 25% were suspected to have had idiopathic epilepsy. [11] In the same group of 91 cats, 50% were secondary seizures and 20% reactive. [11]
Hyponatremia or hyponatraemia is a low concentration of sodium in the blood. [4] It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L), with severe hyponatremia being below 120 mEq/L. [3] [8] Symptoms can be absent, mild or severe.
It is important to note that sudden restoration of blood volume to normal will turn off the stimulus for continued ADH secretion. Hence, a prompt water diuresis will occur. This can cause a sudden and dramatic increase in the serum sodium concentration and place the patient at risk for so-called "central pontine myelinolysis" (CPM). CPM is a ...
Hypernatremia (high blood sodium level, above 145 mEq/L) causes thirst, and due to brain cell shrinkage may cause confusion, muscle twitching, or spasms. With severe elevation, seizures and comas may occur. [11] [12] Death can be caused by ingestion of large amounts of salt at a time (about 1 g per kg of body weight). [13]
Examples of causes of provoked seizures that can be corrected include low blood sugar, low blood sodium, febrile seizures in children, and substance/medication use. Starting anti-seizure medications is usually for those with medium to high risk of seizures re-occurring.
Cats are carnivores. The kidney is a vital organ with a variety of tasks. It plays an important role in maintaining the water, electrolyte and acid-base balance, in the excretion of toxic metabolic degradation products such as urea and in the recovery of valuable substances such as glucose, amino acids, peptides and minerals initially filtered out of the blood during ultrafiltration in the ...
Antiepileptic drugs will be used if the cause is suspected to be seizure related. Phenobarbital is the most effective of these drugs but does not work on every cat. Gabapentin may be used for both its analgesic and antiepileptic properties. It must, however, be xylitol free, as xylitol is toxic substance for several animals. [1] [2] [3] [4]
Common causes in pediatric patients may be diarrheal illness, frequent feedings with dilute formula, water intoxication via excessive consumption, and enemas. [3] Pseudohyponatremia is a false low sodium reading that can be caused by high levels of fats or proteins in the blood.
