Transient global amnesia uptodate

UpToDate , electronic clinical resource tool for physicians. Since the first reports of transient global amnesia (TGA). Conflict of interest policy.

During an episode of TGA, a person is not able to make new memories. Although the etiology is unknown, the prognosis usually benign, and no particular treatment is require it is important. Transient global amnesia (TGA) is a benign, temporary loss of anterograde memory with sparing of immediate recall and remote memories. Worldwide, its incidence is approximately 2. Lauria G, Gentile M, Fassetta G, et al. Lee HY, Kim JH, Weon YC, et al.

Diffusion-weighted imaging in transient global amnesia exposes the CAregion of the hippocampus. The incidence is higher in people years of age and older. Objective: Our main objective is to analyze the epidemiological features of the event and its complementary studies, searching for factors of recurrence. Clinically, it manifests with a paroxysmal, transient loss of memory function. What are normal symptoms after transient global amnesia?

How is transient global amnesia (tga) treated? What is the mechanism of transient global amnesia? How long does transient global amnesia last? This includes the inability to form new memories and recall events that happened.

The etiology of this form of amnesia remains unclear, but certain triggers have been identified (e.g., strenuous physical exercise, psychological stress). The diagnosis of the condition is based on the exclusion of more severe disorders, such as head injury, seizure or stroke that can lead to some form of memory loss. For example, you may not know where you are or how you got there. Although patients may be disoriente not know where they are or be confused about time, they are otherwise alert, attentive and have normal thinking abilities.

The history was entirely consistent with proposed diagnostic criteria for transient global amnesia (TGA). The patient was informed that the episodes were benign, unlikely to recur, required no further investigation or treatment and that there was no restriction to driving imposed by the Driver and Vehicle Licensing Agency (DVLA) guidelines. The precise pathophysiology of transient global amnesia is not clear. The findings reported with positron emission tomography (PET), diffusion-weighted MRI (DWI), single photon emission computed. When this happens you cannot remember events from your recent past or make new memories.

Migraine is associated with a higher risk of transient global amnesia : a nationwide cohort study. Global means that the loss of memory is severe and often total. You may even ask the same question many times.

Amnesia means a loss of memory. What causes many cases of transient global amnesia is not known, but one type is caused by drinking too much alcohol or taking certain drugs. Patient finds it difficult to recollect events before, during, and sometimes after a stressful event that trigger amnesia. Here is a video that briefly explains what transient global amnesia is and what happens to the patient.

We present the case of an elderly male who was diagnosed with transient global amnesia (TGA), only to be diagnosed with B-cell lymphoma with central nervous system involvement a few weeks later. This is the first ever case reported in literature with lymphoma presenting as TGA. Literature review and pertinent points regarding high-yield imaging protocol for presumed TGA patients are discussed.
