can environmental factors cause seizures?
448001
Certain genes may make a person more sensitive to environmental conditions that trigger seizures. Head trauma. Head trauma as a result of a car accident or other traumatic injury can cause epilepsy.

Anything that interrupts the normal connections between nerve cells in the brain can cause a seizure. This includes a high fever, high or low blood sugar, alcohol or drug withdrawal, or a brain concussion. But when a person has 2 or more seizures with no known cause, this is diagnosed as epilepsy.

Sleep disorders include obstructive sleep apnoea, restless legs syndrome, narcolepsy and night terrors. Sleep disorders or disturbances can affect seizures because broken sleep can trigger seizures. So sleep disorders, including the conditions mentioned above can make seizures more likely, as they interfere with sleep.

The electrical activity in the brain during a seizure can also change our pulse and usually causes an increase in heart rate. However, during some seizures, the heart can slow or even stop temporarily, which is referred to as ictal asystole.

RESULTS: Seizures arise in renal failure due to toxins accumulation and to complications like sepsis, hemorrhage, malignant hypertension, pH and hydroelectrolytic disturbances. Hemodialysis leads to acute dysequilibrium syndrome and to dementia. Peritoneal dialysis may cause hyperosmolar non-ketotic coma.

The greatest risk is to brain development, where irreversible damage can occur. Higher levels can damage the kidneys and nervous system in both children and adults. Very high lead levels may cause seizures, unconsciousness and death.

The sudden onslaught of seizures in adult ducks and geese is most commonly the result of some kind of poisoning (see our June 2013 Newsletter for detailed information), but other causes may include: injury, tumors, cancer, malnutrition, heatstroke, organ failure and contagious disease.

Focal seizures take place when abnormal electrical brain function occurs in one or more areas of one side of the brain. Before a focal seizure, your child may have an aura, or signs that a seizure is about to occur. This is more common with a complex focal seizure.

The exact cause of juvenile myoclonic epilepsy remains unknown. It is not associated with conditions such as head trauma, brain tumor , or encephalitis. Family history and genetic factors play a strong role in the risk for juvenile myoclonic epilepsy.
855216
Concussion, traumatic brain injury and seizures. Head trauma is one of the most commonly identified reasons that patients develop epilepsy. Most studies suggest that approximately 6% of patients with epilepsy have TBI as the cause. The more severe the head trauma, the higher the risk of developing epilepsy.

Cannabidiol, or CBD, which does not cause psychoactive effects but has shown some positive effects on certain body systems. This is the part that has been effective in reducing seizures in some people with epilepsy.
584377
The onset of epilepsy is most common in children and older adults, but the condition can occur at any age. Family history. If you have a family history of epilepsy, you may be at an increased risk of developing a seizure disorder. Head injuries.

A stroke occurs due to a disruption of blood circulation in the brain. A seizure occurs due to a surge of electrical activity in the brain. In addition, a stroke can permanently affect your thinking and muscle control. The effects of a seizure are usually temporary.
1090695
Focal seizures take place when abnormal electrical brain function occurs in one or more areas of one side of the brain. Before a focal seizure, your child may have an aura, or signs that a seizure is about to occur.

We know that idiopathic epilepsy is passed down from the dog's parents, but its cause is still unknown. Other causes of dog seizures while sleeping are kidney failure, brain tumors, brain trauma, liver disease, toxins, neoplastic growths, metabolic disorders, and more.

Many children appear to have a genetic predisposition to absence seizures. In general, seizures are caused by abnormal electrical impulses from nerve cells (neurons) in the brain.
