What does it mean when an EEG is abnormal?

An abnormal EEG means that there is a problem in an area of brain activity. This can offer a clue in diagnosing various neurological conditions. Read 10 Conditions Diagnosed With an EEG to learn more. EEG testing is one part of making a diagnosis.

What is abnormal brain activity?

Abnormal electrical activity in the brain can cause seizures. When a person has repeated seizures, this condition is called epilepsy. Diagnosis and treatment of these disorders often requires consultation with a neurologist.

Can an abnormal EEG become normal?

If you aren’t having a seizure at that time, there may not be any unusual brain waves for the test to record. During a seizure, the electrical activity is abnormal. Once the seizure is over, the brain rapidly returns to normal in most individuals.

What disorders Can an EEG detect?

An EEG might also be helpful for diagnosing or treating the following disorders:

• Brain tumor.
• Brain damage from head injury.
• Brain dysfunction that can have a variety of causes (encephalopathy)
• Inflammation of the brain (encephalitis)
• Stroke.
• Sleep disorders.

What can cause abnormal brain activity?

What Abnormal Results Mean

• Abnormal bleeding (hemorrhage)
• An abnormal structure in the brain (such as a brain tumor)
• Tissue death due to a blockage in blood flow (cerebral infarction)
• Drug or alcohol abuse.
• Head injury.
• Migraines (in some cases)
• Seizure disorder (such as epilepsy)
• Sleep disorder (such as narcolepsy)

Can EEG show mental illness?

Electroencephalography, or EEG, technology that measures brain function could encourage earlier diagnoses of common mental and neurological disorders, including autism, ADHD and dementia, according to findings published in The Neurodiagnostic Journal.

What does it mean to have an abnormal EEG?

Abnormal Eeg (Definition) Abnormal EEG (electro-encephalogram) is a test result in which the EEG recording of the brain’s electrical activity shows patterns that are not normal, or that are known to be signs of conditions such as seizures (convulsions, epilepsy ) or sleep disorders.

What are possible results of an EEG?

EEG brain activity An EEG records the electrical activity of your brain via electrodes affixed to your scalp. EEG results show changes in brain activity that may be useful in diagnosing brain conditions, especially epilepsy and other seizure disorders .

What is the normal result of EEG?

Normal results. Electrical activity in the brain appears in an EEG as a pattern of waves. Different levels of consciousness, like sleeping and waking, have a specific range of frequencies of waves per second that are considered normal. For example, the wave patterns move faster when you’re awake than when you’re asleep.

What causes abnormalities in an EKG report?

An imbalance in electrolyte minerals such as potassium, sodium, calcium, or magnesium may cause an abnormal EKG reading. Taking certain medications may cause abnormal EKG results. Some medications may cause an abnormal EKG reading.
