Our findings show that in a real-life clinical scenario, TEA is frequent but often overlooked. In the group with TGA, the only imaging alteration found was diffusion weighted imaging (DWI) hippocampal hyperintensity. Finally, structural abnormalities were more frequent in patients with TEA (26.6%). Transient and persistent amnesia may be the sole or main manifestation of stroke. 1 This definition usefully eliminates the 24-h time limit, but is highly dependent on timely access to diagnostic tes. On the contrary, 24-h EEG showed IEAs in all patients with epilepsy, mostly during sleep, suggesting an essential diagnostic role of long-lasting EEG recording for TEA. More recently, the American Heart Association recommended a ‘tissue-based’ definition of TIA: a transient episode of neurological dysfunction caused by a focal brain, spinal cord, or retinal ischaemia, without acute infarction. The analysis of st-EEG results evidenced low sensitivity for interictal epileptiform abnormalities (IEAs) detection (52.3%), with not conclusive data in distinguishing TEA from TGA. This result could be related with a prolonged postictal state in these patients. In our sample, duration of the episodes did not significantly differ between TGA and TEA, even though it is usually described as shorter for TEA. 001) and atypical symptoms such as confusion or language disorder (TGA plus manifestations), appear to be key elements in order to discriminate between TEA and TGA (80% of patients with TEA vs 7.8% of patients with TGA p <. From a clinical point of view recurrence (p <. Clinical features, neurophysiological, and neuroimaging data were analyzed and compared in the two groups (TEA and TGA).ĭiagnosis of TEA, according to Zeman's criteria, was made in 15 patients (18%). Question Are there physiological, environmental, or other factors that increase risk for recurrence of transient global amnesia. Moreover, patients with borderline epileptiform abnormalities on st-EEG or with normal st-EEG but high clinical suspicion for TEA underwent a 16-channel 24-hour ambulatory EEG (24-h EEG). All patients underwent neurological evaluation, magnetic resonance imaging (MRI) scan, and standard 21-channel scalp electroencephalography (EEG) recording (standard EEG ). We retrospectively collected clinical data of 83 patients who accessed our emergency ward for an abrupt onset of amnesic disorder, initially interpreted as TGA. We designed this study to evaluate the actual frequency of TEA in a real-life scenario and to highlight the features that can help clinicians distinguishing it from TGA. If you have a treatable cause of amnesia, then treatment might allow you to regain your memory.īut if you have ongoing amnesia, then apart from treating whatever is causing it, you will need to developing strategies to improve your memory.Transient epileptic amnesia (TEA) is an underestimated condition in emergency clinical setting, where most of transient amnesic episodes tend to be classified as transient global amnesia (TGA). take images of your brain to look for damage.take a blood test to check for infection or vitamin deficiencies.Your doctor will talk to you and examine you. If you or someone you know are struggling to remember things like close family members' names, or if you can't retain new information, it's important to see your doctor.Īnd if you have any memory loss at all after a head injury or a suspected concussion, you should see your doctor. Transient global amnesia is a sudden, temporary loss of memory for events during, after, and sometimes before the event that caused the amnesia. after losing the supply of oxygen to the brain, such as with a heart attack or heart surgery.a type of epilepsy (transient epileptic amnesia).psychological conditions, such as anxiety or depression.tumours in the area of the brain that control memoryĪmnesia can also be caused by issues that affect the whole brain, such as:.It can be caused by damage to the parts of the brain that are important for memory. There is a long list of conditions that can cause amnesia. ![]() It is usually temporary, but can be permanent in some situations. It is often a symptom of another condition. People who have amnesia might also be confused and have trouble learning anything new.īut most people with amnesia still remember who they are, and can often remember events from their childhood.Īmnesia is not a medical condition on its own, but a description of an experience. People with amnesia can struggle to form new memories or remember recent events or experiences. ![]()
