   • Epilepsy. Epilepsy is a neurological seizure condition that occurs in one of several parts of the brain. The main symptom of epilepsy is recurrent seizures due to unusual electrical brain activity.
   • Sleep disorders. Sleep disorders include problems with the amount or quality of sleep a person has, often due to an underlying physical or emotional cause.
   • Traumatic brain injuries. Head injuries, or traumatic brain injuries (TBIs), occur when a strong force to the head causes damage to the brain, resulting in temporary or permanent impairment of cognitive, physical, and psychosocial functions.
   • Brain infection or inflammation. Brain inflammation, or encephalitis, primarily occurs after a viral infection. Other causes may involve the immune system mistakenly attacking brain tissue.

   If brain waves look irregular, they may indicate a physical or psychological condition. EEGs, short for electroencephalograms, are painless, non-invasive tests that track electrical activity produced when neurons in the brain transmit messages to each other.

   May 1, 2023 · This activity reviews the abnormal waveforms in EEG recordings to help review these abnormalities for the clinical provider and improve patient outcomes. Objectives: Identify various epileptiform abnormalities noted on EEG recordings. Outline the specific electrographic features of epileptiform abnormalities noted on EEG recordings.

   What is abnormal spontaneous activity?

   • Long Davalos; Kapil Arya; Hani Kushlaf. Last Update: July 15, 2023. The muscle is normally electrically silent outside the end-plate zone. Therefore, abnormal spontaneous activity is considered when there is the persistence of spontaneous activity outside of the end-plate zone, usually defined as lasting more than 3 seconds on an EMG recording.

   What are abnormal waveforms seen in an EEG recording?

   • Abnormal waveforms seen in an EEG recording include epileptiform and non-epileptiform abnormalities. In order to identify abnormal waveforms in EEG, the reader should have a basic understanding of the normal EEG pattern in various physiological states in children and adults.

   What causes focal brain dysfunction without structural abnormalities?

   • Focal brain dysfunction without structural abnormalities has been observed in transient ischemic attacks (TIA), migraine, and postictal states. Polymorphic delta activity in these cases may be indistinguishable from that caused by a structural lesion, except that it is short-lived (ie, it disappears over time).

   Is focal slowing an abnormal etiology?

   • To be interpreted as abnormal, these usually require the coexistence of a more definite abnormality such as slowing or epileptiform discharges. As already outlined, focal slowing is nonspecific as to etiology, and in the era of neuroimaging the EEG has no role in diagnosing the nature of a lesion.
