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. The main importance of lesion detection in transient global amnesia (TGA) is to exclude urgent differential diagnoses, such as transient ischemic attack (TIA), seizures, and drug-induced amnesia. 2013-02-01 2019-02-24 Transient global amnesia (TGA) is a reversible, benign, mostly nonrecurrent clinical syndrome of anterograde amnesia lasting up to 24 hours, manifesting as repetitive 2020-08-14 Transient global amnesia (TGA) is characterized by an attack of temporary antero- grade amnesia without other focal neurological deficits. Characteristic magnetic resonance imaging (MRI) findings include small, punctate, unilateral or bilateral diffusion restriction in the lateral aspect of the hippocampus, which mostly occurs within 48 hours after symptoms onset. 2019-01-11 2020-03-06 Methods: MRI findings in 12 patients with clinical diagnosis of TGA were retrospectively analysed.

We studied the relation of TGA, vascular risk factors, brain magnetic resonance 2018-04-06 · Before developing amnesia, she visited another elementary school for a workshop. She did not clearly remember the situation at the onset of TGA. At the first medical examination, she presented with no neurologic deficit, except for amnesia. Magnetic resonance imaging (MRI), electroencephalogram, and laboratory findings were normal. 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 Oct 2019 Background and purpose The aim was to study whether ultra‐high field 7 T magnetic resonance imaging (MRI) can demonstrate chronic focal We evaluated five patients with a diagnosis of transient global amnesia treated between 2012 and 2015.

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. Methods: MRI findings in 12 patients with clinical diagnosis of TGA were retrospectively analysed. The detection rate of diffusion-weighted (DWI) hyperintense lesions varies widely in patients with transient global amnesia (TGA).

With this clinical history and characteristic MRI findings, a diagnosis of transient global amnesia (TGA) was made. TGA is a benign amnestic syndrome, usually lasting less than 24 h. It is characterised by a sudden onset of transient anterograde and retrograde amnesia without focal neurological signs or seizure features, and with other intellectual abilities preserved.

MRI brain was performed with a 3T scanner on 11 patients and 1.5T scanner on 1 patient. DWI were acquired at B value of 1000 s/mm 2 in 4 patients, 2000 s/mm 2 in 2 patients and both 1000 and 2000 s/mm 2 in 6 patients. 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.

Diagnosis is clinical, although diffusion‐weighted images can reveal focal signal alterations in CA‐1 field of hippocampus, when MRI was performed 2 days after the event 8, 10.

The findings reported with positron emission tomography (PET), diffusion-weighted MRI (DWI), single photon emission computed 2010-02-01 · Introduction. The syndrome of transient global amnesia (TGA) was described independently in two case series by Bender 1 and by Guyotat and Courjon 2 in 1956. However, in 1882 and 1909, Ribot 3 and Benon 4 had already described transient amnestic states suggestive of a TGA. 5 In 1964, Fisher and Adams 6 published a large case series and introduced the term as used today. Patients with transient global amnesia (TGA) present with a characteristic clinical syndrome although other differential diagnoses have to be considered.

PURPOSE: Patients with transient global amnesia (TGA) present with a characteristic clinical syndrome although other differential diagnoses have to be considered. Diffusion-weighted imaging (DWI) represents a highly specific diagnostic tool in the context of TGA; however, standard clinical DWI often fails to detect the small characteristic Background Transient global amnesia is a well-described complication of cerebral angiography.
