Non-epileptic seizures are episodes that briefly affect brain function and look like epileptic seizures. The brain is not sending abnormal signals as it does during an epileptic seizure. Instead, non-epileptic seizures are a physical manifestation of psychological distress. Non-epileptic seizures are also known as psychogenic non-epileptic seizures (PNES).
Causes[edit]
Non-epileptic seizures are caused by psychological conditions, such as mental stress and mental health disorders, including post-traumatic stress disorder (PTSD), depression, and anxiety. They are not caused by epilepsy or other physical or neurological conditions.
Symptoms[edit]
Symptoms of non-epileptic seizures can resemble those of epileptic seizures, such as:
- Convulsions
- Loss of consciousness
- Falling
- Shaking or jerking movements
- Temporary paralysis
- Emotional distress or anxiety before the seizure
Diagnosis[edit]
Non-epileptic seizures are diagnosed through a combination of medical history, physical examination, and tests. The most common test is an electroencephalogram (EEG), which measures electrical activity in the brain. During a non-epileptic seizure, the EEG does not show the abnormal brain activity that is seen in an epileptic seizure.
Treatment[edit]
Treatment for non-epileptic seizures involves addressing the underlying psychological issue. This may involve psychotherapy, cognitive behavioral therapy (CBT), and medication for any mental health disorders.
Prognosis[edit]
With appropriate treatment, many people with non-epileptic seizures can reduce or eliminate their seizures. However, the underlying psychological issues need to be addressed to prevent the seizures from returning.
