Focal unaware cognitive seizures in elderly maybe be blamed on dementia, and ictal or interictal psychosis in frontal and temporal lobe epilepsies may be mistaken for a primary psychiatric disorder.

The brain consists of nerve cells that communicate with each other through electrical activity. It affects children and adults of all races and ethnic backgrounds. is one of the most common disorders of the nervous system. Frontal lobe hypermotor seizures may be misdiagnosed as psychogenic events. Epilepsy is a brain condition that causes a child to have seizures. The diagnosis of epilepsy can be challenging, and some seizure types may be underdiagnosed. Tests (including EEG) should not be overemphasized over clinical judgment. The lack of mandatory training in neurology residency programs is one of the main reasons for normal EEGs being over-read as abnormal. Reversing the diagnosis of epilepsy is challenging and requires reviewing the 'abnormal' EEG, which can be difficult. Reasons for reading a normal EEG as an abnormal one include over-reading normal variants or simple fluctuations of background rhythms. Most patients misdiagnosed with epilepsy turn out to have either psychogenic nonepileptic attacks or syncope. Twenty-five to 30% of patients previously diagnosed with epilepsy who did not respond to initial antiepileptic drug treatment do not have epilepsy. An erroneous diagnosis of epilepsy is often the result of weak history and an 'abnormal' EEG. Epilepsy is more commonly overdiagnosed than underdiagnosed. The diagnosis of epilepsy in general is a clinical one and is typically based on history. These signals tell other parts of the brain and body. Neurons normally create tiny electrical signals in a regular rhythm. Epilepsy is a type of seizure disorder in which clusters of nerve cells in the brain (neurons) behave abnormally. Errors in neurology are often because of the overemphasis on 'tests' over the clinical picture. Epilepsy is a neurological (brain) disease that causes people to have seizures. The consequences can be serious for both patients and physicians. Errors in diagnosis are relatively common in medicine and occur in all specialties.
