The detection rate of diffusion-weighted (DWI) hyperintense lesions varies widely in patients with transient global amnesia (TGA). The aim was to examine the association of hyperintense lesions on DWI magnetic resonance imaging (MRI) with patient characteristics, precipitating factors, clinical presentation and MRI settings in patients with TGA.

We analyzed demographic characteristics, clinical data, Transient global amnesia (TGA) is a well known clinical entity characterized by anterograde memory disturbance of sudden onset that lasts 1 to 24 hours. Her hospital work-up was overall unremarkable except for the presence of a diffusion weighted imaging (DWI) abnormality on MRI suggestive of acute infarction in We made a clinical diagnosis of transient global amnesia (TGA). Brain diffusion- weighted MRI at 48 h postevent showed focal bilateral medial temporal lobe 22 Jun 2020 Transient global amnesia (TGA) is a clinical syndrome characterized by the acute onset of anterograde amnesia (the inability to form new memories).Patients with. MRI findings in transient global amnesia Transient global amnesia is a disorder characterized by an attack of temporary anterograde amnesia with no other focal neurological symptoms. Recent studies 26 Mar 2021 PDF | Introduction: Aim of this study is to identify and describe the MRI findings in patients with Transient Global Amnesia (TGA), specifically on.

Conclusion MRI findings can support the diagnosis of TGA and may be particularly valuable in situations of low clinical certainty. DWI—ideally performed with a minimum delay of 20 hours after onset—should therefore be considered a useful adjunct to the diagnosis of TGA. Hippocampal lesions are found on DWI MRI in most patients with transient global amnesia, whether witnessed or unwitnessed. 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. 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. Transient global amnesia (TGA) is an episodic dysfunction of declarative memory that usually resolves within 12 hours and whose underlying pathophysiological mechanisms are still unclear. Recent studies, on the basis of transient focal high-signal abnormalities in the hippocampus on diffusion-weight … Key Words: transient global amnesia amnestic syndrome magnetic resonance imaging diffusion-weighted imaging risk factors T ransient global amnesia (TGA) is characterized by an-terograde memory disturbance of sudden onset that lasts for 1 to 24 hours.1 Orientation in space and time is impaired while consciousness remains undisturbed.

BACKGROUND AND PURPOSE: Transient global amnesia (TGA) is characterized by sudden anterograde and retrograde amnesia lasting for up to 24 hours. Diffusion-weighted magnetic resonance imaging (DWI) in cases of TGA and ischemia demonstrates a high frequency of high signal intensities restricted to the hippocampus, and this has

While the diagnosis of TGA is based on its clinical features, neuroimaging is important to exclude other sinister causes of global amnesia. Furthermore, classical MRI changes in TGA have been well described in the literature.

Few studies have investigated transient global amnesia (TGA) in the context of a concussion and the concussion sequelae following TGA. Here we review the case of a 43-year-old male with onset of transient global anterograde and retrograde amnesia 22 days after a sustained concussion. The patient's head CT, MRI of brain, and EEG were reported normal, and the patient regained full cognitive

1–3 The incidence of TGA has been reported to be 5–11 per 100,000 persons per annum. 2,4,5 The etiology and pathogenesis of TGA are uncertain, though several Transient global amnesia (TGA) has been a well-described phenomenon for more than 40 years. Clinically, it manifests with a paroxysmal, transient loss of memory function. Immediate recall ability Abstract. Die transiente globale Amnesie (TGA) ist eine akut auftretende Gedächtnisstörung unbekannter Ursache.

DWI were 2017-08-28 2012-03-16 Transient global amnesia (TGA) is a neurological disorder whose key defining characteristic is a temporary but almost total disruption of short-term memory with a range of problems accessing older memories. A person in a state of TGA exhibits no other signs of impaired cognitive functioning but recalls only the last few moments of consciousness, as well as possibly a few deeply encoded facts Diffusion-weighted MRI may be useful in defining the pathophysiology. Transient global amnesia refers to a syndrome of temporary anterograde and recent retrograde memory loss with preservation of alertness, attention, and self-identity, without other significant accompanying neurological symptoms. 2018-01-01 2005-03-01 BACKGROUND AND PURPOSE: Transient global amnesia (TGA) is characterized by sudden anterograde and retrograde amnesia lasting for up to 24 hours.

Characteristic magnetic resonance imaging (MRI) ﬁ ndings include small, punctate, unilateral or bilateral diffusion restriction in the lateral aspect of the hippocampus, which mostly occurs Transient global amnesia: hippocampal magnetic resonance imaging abnormalities Transient global amnesia (TGA) is an episodic dysfunction of declarative memory that usually resolves within 12 hours and whose underlying pathophysiological mechanisms are still unclear. Patienter med transitorisk global amnesi (TGA) kan påträffas inom alla specialiteter, men kanske främst på en medicinsk akutmottagning eller vårdcentral. TGA karakteriseras av en tillfällig, akut insättande oförmåga att inprägla och behålla minnen, vilket varar mellan 2 och 3 upp till 24 timmar [1-3].
