Retention of personal identity despite memory loss. Normal cognition, such as the ability to recognize and name familiar objects and follow simple directions. During an episode of TGA , a person is not able to make new memories. While amnesia is the most prominent feature, some patients complain of headaches, nausea, dizziness or other symptoms during an episode of TGA. Sometimes transient global amnesia may be triggered by emotional events.
Postural changes, high altitude, strenuous exercise or bearing down may also precipitate an episode. Although patients may be disoriente not know where they are or be confused about time, they are otherwise alert, attentive and have normal thinking abilities. Clinically, it manifests with a paroxysmal, transient loss of memory function.
In some cases (up to ), symptoms may be preceded by physical effort (e.g. lifting shopping bags), (emotional) stress, coughing, or pain. Sometimes changes of temperature can pose as a trigger for the attack, especially changes from warm to cold. Patients with TGA typically have no difficulties recognizing family members, and can recall things from the past. What is global amnesia?
During a TGA episode, a person cannot form new memories and has difficulty recalling recent memories. You may not be able to remember information or experiences from the recent past, or remember new information. For example, you may not know where you are or how you got there. 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. Patients are often disoriented in regard to time and place but usually not personal identity. Most symptoms are transient and resolve within a few hours. Although the etiology is unknown, the prognosis usually benign, and no particular treatment is require it is important for all involved clinicians to recognize the diagnosis and possess knowledge about the evaluation of these affected patients. The etiology of TGA remains obscure.
History of a migraine, stroke and epilepsy. Recent sexual activity. Psychological disturbances. The sudden change of temperature.
It almost never happens to anyone under the age of 5 and its frequency among people over is estimated to about out of. It is sudden in onset an the patient becomes normal without any treatment. This syndrome is generally seen in elderly people. The person will have normal focal, motor, speech and sensory functions. In transient global amnesia (TGA) the individual does not lose consciousness but does lose the ability to form new lasting memories.
Motor function is not affected. The rest of the cognitive functions (consciousness, personal identity, attention…) remain intact. Symptoms of amnesia Retrograde amnesia.
When you have retrograde amnesia, you lose existing, previously made memories. Background and Purpose The purpose of the present study was to make an attempt to ascertain the etiology of transient global amnesia (TGA), which is still disputed more than years after the first description of this clinical entity. Methods In a case-control study, we compared the prevalence of vascular risk factors in TGA patients.
