![]() ![]() Other studies have also suggested that TGA patients are more likely to carry a psychopathological personality or demonstrate an emotional instability. Īlthough little is known regarding the etiology of TGA, empirical evidence suggests a higher than expected prevalence of precipitating events, including both emotionally and physically stressful situations before the onset of TGA episodes. Given a lack of diagnostic tests, TGA remains a clinical diagnosis where other causes of amnesia such as epilepsy or stroke need to be excluded. The incidence is largely age dependent and among middle aged and older individuals, the incidence has been estimated to reach 30 cases per 100,000 person-years. TGA occurs most common at the age of 50–80 years and has an overall incidence of 5–11 per 100,000 person-years. Transient global amnesia (TGA) is one of the most striking syndromes in clinical neurology, characterized by a sudden onset of profound global amnesia (both retrograde and anterograde) which usually lasts less than 24 hours and typically resolves within a few hours.
