Causes and Prevention of Seizures in Dogs Causes and Prevention of Seizures in Dogs. Causes of Seizures in Dogs. Seizures are the most common neurological abnormality in companion dogs. In the broadest of terms, seizures are caused by abnormally large bursts of electrical activity inside the brain. Seizures happen because of conditions, events or defects that originate either inside of the skull (intracranially) or outside of the skull (extracranially).

Overview Causes. Grand mal seizures occur when the electrical activity over the whole surface of the brain becomes abnormally synchronized. The brain's nerve cells normally communicate with each other by sending electrical and chemical signals across the synapses that connect the cells. In people who have seizures, the brain's usual electrical activity is altered.

Opiate Withdrawal and Seizures Seizures are symptoms of a brain problem. They happen because of sudden, abnormal electrical activity in the brain. When people think of seizures, they often think of convulsions in which a person's body shakes rapidly and uncontrollably. Not all seizures cause convulsions. There are many types of seizures and some have mild symptoms. Seizures fall into two main groups. Focal seizures, also called partial seizures, happen in just one part of the brain.

Seizures A seizure (also called a fit, spell, convulsion, or attack) is the visible sign of a problem in the electrical system that controls your brain. A single seizure can have many causes, such as a high fever, lack of oxygen, poisoning, trauma, a tumor, infection, or after brain surgery. Most seizures are controlled with medication. If your seizures occur repeatedly, then you may have the chronic disorder called epilepsy.
