Panic attacks can occur without a trigger whereas anxiety usually occurs in response to a perceived stressor or threat. What’s the difference between a panic attack and an anxiety attack? Many conditions have symptoms similar to epilepsy, including first seizures, febrile seizures, nonepileptic events, eclampsia, meningitis, encephalitis, and migraine headaches.First Seizures. What are the symptoms of an anxiety attack?Īnxiety and PanicSudden overwhelming .Shortness of breath.Sense of choking.Chest pain.Nausea.

Some people with epilepsy are told they are having panic attacks, when they are actually experiencing seizures. This means that both conditions can be misdiagnosed. The symptoms of anxiety – particularly panic attacks – can look and feel a lot like the symptoms of some types of epileptic seizure. To date, no QEEG methods have been accepted as reliable independent markers for psychiatric disorders or treatment response. Quantitative frequency analysis of EEG data (QEEG) is useful in research and exceptionally as a supplement to diagnosis in clinical settings. However, if your tremors also affect your daily activities, you may want to see a neurologist. You may want to see a neurologist if these movement problems interrupt your daily life, though something like a tremor can be a side effect of medication or anxiety. The condition is highly responsive to brainwave training. The condition is often quite obvious in the EEG. We see anxiety as one manifestation of diminished self-regulation by the brain. These waves may or may not show evidence of seizure activity. The EEG generally records brain waves between seizures, called interictal brain waves. A major contributor to the misdiagnosis of epi- lepsy is the tendency to over-read normal tracings as abnormal. (weak) EEG abnormality is a common cause of inappropriate diagnoses of seizures…” The misdiagnosis of epilepsy is common and has very serious consequences. What are the possible causes for an abnormal EEG?Ībnormal results on an EEG test may be due to: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) Can you have a false abnormal EEG? EEG testing is one part of making a diagnosis. Read 10 Conditions Diagnosed With an EEG to learn more. This can offer a clue in diagnosing various neurological conditions. What happens if EEG is abnormal?Īn abnormal EEG means that there is a problem in an area of brain activity. They’re sometimes used to evaluate brain activity after a severe head injury or before a heart transplant or liver transplant. EEGs also can identify causes of other problems, such as sleep disorders and changes in behavior. Why It’s Done Most EEGs are done to diagnose and monitor seizure disorders. In fact, since the EEG records only a 30-minute snapshot of the brain’s activity, many EEGs are normal. A normal EEG does not rule out the possibility of epilepsy.

Your neurologist reads the EEG to look for clues in the brain’s activity that may help define the cause or type of seizure.
It can also be used to confirm brain death. The test is used to help diagnose conditions such as seizures, epilepsy, head injuries, dizziness, headaches, brain tumors and sleeping problems. What problems can an EEG detect?Īn electroencephalogram (EEG) is a noninvasive test that records electrical patterns in your brain. An electroencephalogram (EEG) is a test that detects electrical activity in your brain using small, metal discs (electrodes) attached to your scalp. EEG results show changes in brain activity that may be useful in diagnosing brain conditions, especially epilepsy and other seizure disorders.
