National Epilepsy Awareness Month

November is observed as National Epilepsy Awareness Month. Epilepsy is a neurological disorder characterized by recurrent seizures. It affects people of all ages and can greatly impact daily life.  

Epilepsy is a lot more common than people realize, as approximately one in 26 people will develop epilepsy at some point in their lives. Additionally, 470,000 children in the U.S. live with epilepsy, with approximately one in 150 children diagnosed with epilepsy.  

Epilepsy can manifest in various forms. The disorder is classified based on seizure type and underlying cause: 

  • Generalized epilepsy affects both hemispheres of the brain, resulting in widespread symptoms, such as convulsions or absence seizures 
  • Focal epilepsy is limited to one area of the brain, which often causes localized symptoms, such as sensory changes or motor disruptions 
  • Unknown or idiopathic epilepsy is when the underlying cause of seizures can’t be determined  

Terms like seizures and epilepsy are often used interchangeably. However, these terms are distinct concepts with unique characteristics and implications.  

When a person has had two or more seizures more than twenty-four hours apart that haven’t been brought on by specific events, such as a stroke, brain injury, infection, fever, or fluctuations in blood sugar, they are considered to have epilepsy. A person can also be diagnosed with epilepsy if they have one or more unprovoked seizures and a probability of future seizures. 

A seizure is a single event. It is an electrical disturbance in the brain that interferes with its normal function. Scientists and clinicians compare it to an “electrical storm in the brain” in which brain cells hyper-synchronize in an abnormal pattern, disrupting the brain signal balance.  

Seizures vary from person to person depending on which type of seizures they experience. This is due to epilepsy being a spectrum disorder, which means the causes, type, and severity can differ greatly for those affected by it. 

Common types of seizures include: 

  • Tonic-clonic seizures 
  • Absence seizures 
  • Focal seizures 
  • Febrile seizures 

The exact causes of epilepsy vary and aren’t entirely known. Typically, epilepsy and seizures result from abnormal signals from neurons in the brain. It can be genetic or acquired through events, such as physical injury or infection. What’s more, the cause of up to 50% of epilepsy cases worldwide is idiopathic, which means unknown. 

Some underlying causes of acquired epilepsy include: 

  • Head trauma 
  • Brain structure abnormalities 
  • Infectious disease 
  • Stroke 
  • Tumor 

 Healthcare providers diagnose epilepsy by conducting tests to detect abnormalities in a patient’s brainwaves. Tests can also detect seizure activity, including where a seizure starts in the brain.  

The most common diagnostic test for epilepsy is the EEG. However, other brain scans, such as MRI or PET, can be used depending on the patient’s seizure, epilepsy type, or both. To determine whether a patient has epilepsy, a healthcare provider compares their test results to the guidelines and criteria established by the International League Against Epilepsy (ILAE). 

To treat epilepsy, healthcare providers prescribe a patient’s treatment based on the type or types of seizures they are experiencing.  

Epilepsy treatments available include: 

  • Medications 
  • Dietary changes 
  • Medical devices 
  • Surgery  

It is important to note that finding the right treatment plan may require trial and error. 

Living with epilepsy requires careful management of triggers, following medication regimens, and awareness of safety precautions. Staying informed about epilepsy and building a strong support system can help individuals lead fulfilling lives despite the difficulties the disorder creates. 

If you are experiencing any symptoms of epilepsy, you can consult with a neurologist at Jamaica Hospital Medical Center. To schedule an appointment, please call (718) 206-7246.

World Epilepsy Awareness Day (Purple Day)

World Epilepsy Awareness Day, or Purple Day, is observed on March 26th, a global initiative to raise awareness of epilepsy and support the millions of people living with it worldwide. 

Approximately 65 million people are living with epilepsy across the world, and one in 26 people in the U.S. will be diagnosed with epilepsy during their lifetime.  

Epilepsy is a brain condition that causes recurring seizures. Most people who suffer from epilepsy generally have the same type of seizure each time, and symptoms are usually similar from episode to episode. The symptoms of seizures can vary depending on the type of seizure, and because epilepsy is caused by certain activity in the brain, seizures can affect any brain process. Seizure symptoms may include: 

  • Short-term confusion. 
  • A staring spell. 
  • Stiff muscles. 
  • Jerking movements of the arms and legs. 
  • Loss of consciousness. 
  • Psychological symptoms such as fear, anxiety, or déjà vu. 

Sometimes people with epilepsy may have changes in their behavior and may also experience psychosis. 

Seizures can be categorized as either focal or generalized, based on where in the brain the brain activity that causes the seizure originates. 

Focal seizures are the result of brain activity in just one area of the brain. Focal seizures can fall into two categories: focal seizures with preserved consciousness or focal seizures with impaired consciousness.  

Types of focal seizures include: 

  • Temporal lobe seizures 
  • Frontal lobe seizures 
  • Occipital lobe seizures 

Focal seizures may have warning signs called auras in the moments before a seizure begins. Auras might include a feeling in the stomach, emotions such as fear, or the feeling of déjà vu. They can also be a taste, a smell, or a visual, such as a steady or flashing light, a color, or a shape. Some people may even experience dizziness and loss of balance, or hallucinations.  

Generalized seizures are seizures that involve all areas of the brain. Types of generalized seizures include: 

  • Absence seizures 
  • Tonic seizures 
  • Atonic seizures 
  • Clonic seizures 
  • Myoclonic seizures 
  • Tonic-clonic seizures 

There is no identifiable cause of epilepsy in about half of the people with the condition. In the other half, the condition may be traced to various factors, including: 

  • Family history of epilepsy 
  • Head trauma 
  • Brain tumors 
  • Infections, such as meningitis, HIV, viral encephalitis, and some parasitic infections 
  • Abnormal blood vessel formation or bleeding in the brain 
  • Alzheimer’s disease 
  • Strokes, heart attacks, and other conditions that deprive the brain of oxygen 
  • Brain inflammation or swelling  
  • Alcoholism or alcohol withdrawal 
  • Injury before birth 
  • Developmental conditions 

Seizures can be caused by environmental triggers. These seizure triggers don’t cause epilepsy, but they may trigger seizures in people who suffer from epilepsy. Most people with epilepsy don’t have reliable triggers that always cause seizures. However, there are often factors that make it easier to have a seizure, including: 

  • Flashing lights  
  • Alcohol 
  • Illicit drug use 
  • Lack of sleep 
  • Stress 
  • Dehydration 
  • Skipping doses of anti-seizure medicines or taking more than prescribed 
  • Skipped meals 
  • Illness  

Epilepsy is diagnosed when a healthcare provider reviews your symptoms and medical history. They may perform several tests to diagnose epilepsy and to detect the cause of seizures. These tests include: 

  • A neurological exam 
  • Blood tests 
  • Genetic testing 

A healthcare provider may also request brain-imaging tests and scans that detect brain changes, including: 

  • Electroencephalogram (EEG) 
  • High-density EEG 
  • CT scan 
  • MRI 
  • Functional MRI (fMRI) 
  • PET scan 
  • Single-photon emission computerized tomography (SPECT) 
  • Neuropsychological tests 

Along with the test results of these brain-imaging tests, a combination of other techniques may be used to help pinpoint where the seizures start in the brain. They include: 

  • Statistical parametric mapping (SPM) 
  • Electrical source imaging (ESI) 
  • Magnetoencephalography (MEG) 

Treatment can help people who have been diagnosed with epilepsy have fewer seizures or even completely stop having seizures. These treatments include: 

  • Medicines 
  • Therapies that include devices that stimulate the brain 
  • Surgery 
  • A ketogenic diet
