Global Transient Amnesia as the Predominant Symptom of Cardiac Myxoma: A Case Report.

BACKGROUND The most common neurological symptoms from cardiac myxoma-induced stroke include territories of middle cerebral arteries, rendering posterior stroke less common. Although transient global amnesia usually has a benign prognosis, amnesia in the setting of concerning cerebellar symptoms should raise the suspicion for posterior circulation involvement. These benign-appearing symptoms can be manifestations of an acute cerebrovascular accident (CVA).

The link between reversible cerebral vasoconstriction syndrome and transient global amnesia.

Reversible cerebral vasoconstriction syndrome (RCVS) and transient global amnesia (TGA) are acute and self-limiting intra-cerebral conditions. Although previously studied as independent phenomena, there are increasing reports of co-occurrence of these two pathologies. We report a 55-year-old male who presented to the hospital with recurrent thunderclap headaches over the course of 1 week with sudden onset of anterograde memory loss.

Transient global amnesia - hippocampal lesions in magnetic resonance imaging.

Background: Transient global amnesia is a benign syndrome characterized by a sudden onset loss of anterograde amnesia with full recovery. Magnetic resonance of the brain including diffusion-weighted imaging of patients with transient global amnesia revealed the presence of punctate hyperintense signal abnormalities in the hippocampus.

Objective: Analysis of the presence of hippocampal lesions in brain magnetic resonance imaging in patients with transient global amnesia and the possible influence of additional factors on their appearance.

EPIAMNE: A New Scoring System for Differentiating Transient EPIleptic AMNEsia from Transient Global Amnesia.

Transient epileptic amnesia (TEA) is a rare cause of acute amnestic syndromes (AAS), often misdiagnosed as transient global amnesia (TGA). We proposed a scoring system—the EPIlepsy AMNEsia (EPIAMNE) score—using quantitative EEG (qEEG) analysis to obtain a tool for differentiating TEA from TGA. We retrospectively reviewed clinical information and standard EEGs (stEEG) of 19 patients with TEA and 21 with TGA.

Transient global amnesia: Uncommon diagnosis of exclusion.

Transient global amnesia (TGA) is an uncommon clinical syndrome characterized by short-term memory loss and disorientation that resolves in 24 h. Here, we report a 60-year-old male patient who presented with a sudden onset of disorientation and short-term memory loss and started to ask about his whereabouts and what happened. He had no significant past medical or psychiatric disorder.

A Case of Transient Global Amnesia Triggered by Sexual Intercourse.

Transient global amnesia (TGA) is described as a sudden onset of anterograde and retrograde amnesia. In this case report, we present a case of a 52-year-old man who came to our hospital experiencing sudden-onset confusion and memory loss an hour after engaging in sexual activity with his wife. Before this, the patient had no previous medical history.

Transient Global Amnesia Recurrence: Prevalence and Risk Factor Meta-analysis.

Background And Objectives: Transient global amnesia (TGA) is an acute amnestic disorder with unclear pathophysiology. Although considered a benign phenomenon, the possibility of a recurrence is a major concern for the patient. Our objective is to identify the prevalence and risk factors of relapse to help clinicians counsel patients about it.

[Transient Global Amnesia in the Reykjavik area].

Background: Transient Global Amnesia (TGA) is a benign syndrome characterized by sudden anterograde memory loss, that resolves spontaneously within 24 hours. TGA appears without other focal neurological symptoms. The aim of this study was to study TGA in the greater Reykjavik-area.

Transient Global Amnesia Masquerading as Transient Ischemic Attack.

Transient global amnesia (TGA) is a rare self-limited syndrome characterized primarily by anterograde amnesia. It shares multiple characteristics with a transient ischemic attack and ischemic stroke, which carry a more ominous outlook. There is a debate with respect to what is sufficient for ruling out more serious pathologies.

Transient Global Amnesia (TGA): Sex-Specific Differences in Blood Pressure and Cerebral Microangiopathy in Patients with TGA.

Transient global amnesia (TGA) is defined by an acute memory disturbance of unclear aetiology for a period of less than 24 h. Observed psychological, neuroanatomical and hormonal differences between the sexes in episodic memory suggest sex-specific differences in memory disorders such as TGA. The aim of this study was to determine sex-specific differences in cardiovascular risk profiles, recurrences and magnetic resonance imaging (MRI).

Network localization of transient global amnesia beyond the hippocampus.

Background: Transient global amnesia is common in the older adult, but the cause and mechanism remain unclear. Focal brain lesions allow for causal links between the lesion location and resulting symptoms, and we based on the reported TGA-causing lesions and used lesion network mapping to explore the causal neuroanatomical substrate of TGA.

Methods: Fifty-one cases of transient global amnesias with DWI lesions from the literature were identified, and clinical data were extracted and analyzed.

Transient global amnesia after COVID-19: A systematic scoping review of case reports.

Transient global amnesia (TGA) is a sudden-onset transient memory impairment along with intact neurologic examinations. Even though it is a benign neurologic condition with many differential diagnoses, the incidence rate of TGA is reported to have increased since the onset of the pandemic. Therefore, this systematic scoping review aims to investigate TGA in that context.

Diagnostic yield of diffusion-weighted brain MR imaging in patients with cognitive impairment: Large cohort study with 3,298 patients.

Objective: There is a paucity of large cohort-based evidence regarding the need and added value of diffusion-weighted imaging (DWI) in patients attending outpatient clinic for cognitive impairment. We aimed to evaluate the diagnostic yield of DWI in patients attending outpatient clinic for cognitive impairment.

Materials And Methods: This retrospective, observational, single-institution study included 3,298 consecutive patients (mean age ± SD, 71 years ± 10; 1,976 women) attending outpatient clinic for cognitive impairment with clinical dementia rating ≥ 0.

The Man Who Mistook a Hat for His Wife: Case Report of Aortic Dissection Presenting With Acute Hyperfamiliarity for Faces.

Acute aortic dissection is a challenging diagnosis for emergency physicians because of its high mortality and wide range of clinical presentations. We report a case of a previously healthy man who presented with hyperfamiliarity for faces syndrome as the predominant symptom of a large type A aortic dissection diagnosed by computed tomography angiography in the emergency department. Different elements of his presentation suggested possible other diagnoses, including transient global amnesia and transient ischemic attack.

Transient Global Amnesia Related to the Third Coronavirus Disease-19 (COVID-19) Vaccination.

We present a case report of transient global amnesia (TGA) after vaccinating the third dose of coronavirus disease-19 (COVID-19). A 65-year-old Japanese woman presented with TGA after her third vaccination, which spontaneously resolved. This article aims to facilitate the clinicians' understanding that TGA could occur after the COVID-19 vaccination in the COVID-19 global outbreak.

Transient global amnesia with unexpected clinical and radiological findings: A case series and systematic review.

Background: Transient global amnesia (TGA) represents a benign neurological syndrome of unknown pathophysiology, often accompanied by vanishing hippocampal punctate diffusion-weighted imaging lesions (HPDL). The literature suggests that TGA may present with unusual features. This study analyses atypical clinical and radiological manifestations of patients with TGA and/or HPDL.

[Transient epileptic amnesia-A rare phenomenon in temporal lobe epilepsies].

Background: Transient epileptic amnesia (TEA) is a rare phenomenon in temporal lobe epilepsy that is often unrecognized or misdiagnosed as transient global amnesia (TGA). It is postulated that TEA is due to both ictal and postictal disturbances. Response to antiseizure medication underlines its epileptic nature.

Forgetting the Unforgettable: Transient Global Amnesia Part II: A Clinical Road Map.

Transient global amnesia (TGA) is a clinical syndrome characterized by the sudden onset of a temporary memory disorder with profound anterograde amnesia and a variable impairment of the past memory. Usually, the attacks are preceded by a precipitating event, last up to 24 h and are not associated with other neurological deficits. Diagnosis can be challenging because the identification of TGA requires the exclusion of some acute amnestic syndromes that occur in emergency situations and share structural or functional alterations of memory circuits.
