Transient global amnesia is anterograde and usually retrograde amnesia that begins suddenly and lasts up to 24 hours. Diagnosis is primarily clinical but includes laboratory tests and CT, MRI, or both. The amnesia typically remits spontaneously but may recur. There is no specific treatment, but underlying abnormalities are corrected.

A few minutes after completion of the procedure, the patient developed symptoms suggestive for transient global amnesia. The brain MRI performed 22 hours after the onset of symptoms demonstrated increased signal within the lateral part of the right hippocampus on the diffusion-weighted imaging (DWI) sequences, associated with a corresponding reduction in the apparent diffusion coefficient (ADC) and increased signal on the fluid-attenuated inversion recovery (FLAIR) sequences, consistent with Transient global amnesia (TGA) is a temporary loss of short-term memory without other signs of impaired cognition and with absent focal neurological signs. The diagnostic criteria include that the attack should have been witnessed, there was no seizure or head injury, and the symptoms resolve within 24 hours. All patients underwent neurological evaluation, magnetic resonance imaging (MRI) scan, and standard 21-channel scalp electroencephalography (EEG) recording (standard EEG [st-EEG]). 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).

Transient global amnesia (TGA) is a reversible, benign, mostly nonrecurrent clinical syndrome of anterograde amnesia lasting up to 24 hours in the absence of other neurologic symptoms. Se hela listan på mayoclinic.org When transient global amnesia first occurs, MRI does not show specific abnormalities. However, after a few days, MRI may show tiny dots in an area of the brain that is important in forming and retrieving memories (the hippocampus). The spots may represent small areas where blood flow is decreased, suggesting a possible cause of the amnesia. Despite transient global amnesia is considered unusual in Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) and causal relation is still unclear, this report suggests to consider CADASIL in those patients with recurrent transient global amnesia, especially when MRI shows multifocal hyperintensities affecting the cerebral white matter or when it is followed by cognitive decline.

Although fi rst described at least 60 years ago,1 the etiology and pathophysiology of TGA remain unclear and have Transient global amnesia is a disorder characterized by an attack of temporary anterograde amnesia with no other focal neurological symptoms. Recent studies showed that the characteristic MRI findings of this disorder are small punctuate diffusion restricted lesions in the CA1 area of the hippocampal formation.

Magnetic resonance imaging (MRI) of the brain performed 48 h after the onset of symptoms demonstrated focal dot-like diffusion restriction in the right and left hippocampi (Figure 1). With this clinical history and characteristic MRI findings, a diagnosis of transient global amnesia (TGA) was made. Figure 1 Open in new tabDownload slide MRI Findings in Transient Global Amnesia T ransient global amnesia (TGA) is a disorder characterized by a sudden attack of severe anterograde amnesia, where patients are unable to learn and recall novel information during the event. Although fi rst described at least 60 years ago,1 the etiology and pathophysiology of TGA remain unclear and have Diagnosis of transient global amnesia rests on excluding more-serious conditions — stroke, seizure or head injury, for example — that can cause the same type of memory loss. When transient global amnesia first occurs, MRI does not show specific abnormalities. However, after a few days, MRI may show tiny dots in an area of the brain that is important in forming and retrieving memories (the hippocampus). The spots may represent small areas where blood flow is decreased, suggesting a possible cause of the amnesia.

A 12-lead ECG and haematological investigations were normal. We made a clinical diagnosis of transient global amnesia (TGA). Brain diffusion-weighted MRI at 48 h postevent showed focal bilateral medial temporal lobe high signal with restricted diffusion . Other sequences were normal.

More global amnesia … 2008-08-01 Transient global amnesia Prevention No standard preventive approaches for TGA tend to exist as the cause of the disease is unknown and its rate of recurrence is low. In case an episode of TGA occurs after a specific activity like swimming in very cold waters or working out severely, it is better to consult a doctor about what can be done. 2010-02-01 Introduction: Aim of this study is to identify and describe the MRI findings in patients with Transient Global Amnesia (TGA), specifically on Diffusion Weighted Imaging (DWI) sequence.
