Transient epileptic amnesia and transient global amnesia both exhibit temporary memory loss. The lack of clues of epileptic events and the absence of epileptiform abnormalities in electroencephalography, a clear brain lesion, and interictal cognitive decline can make diagnoses challenging. Here we present a middle-aged female who experienced long-term recurrent transient epileptic amnesia with subtle epileptic features over a period of 3 years.

The oriental-western Literatural study of Amnesia, the results were as follows. 1. esia is caused by qi-depression resulted from excessive thought and deficiency of the kidney resulted from congenital deficiency and deficiency of the heart, the disharmony between the heart and the kidney, phlegm, stagnant blood, loss of the blood etc. resulted from deficiency of the heart blood. 2. The treatment method of Amnesia is as follows, the highest frequence was growing blood-tranquilization-regulating spleen, in descending order removing phlegm-stagnant blood-relaxing the mind and invigorate the heart-spleen-kidney and much tonification qi-blood and growing nutrient qi-manifesting source qi and regulating the harmony between the heart and the kidney and maintaining patency for the flow of gi were the most treatment method. 3. The treatment medicine of Amnesia is as follows, the highest frequence was Kuei Bi Tang(歸脾湯) in decending order Jeng Ji Whan(定志丸), Su Seng Whan(壽星丸), Chun Whang Boo Sim Dan(天王補心丹), Ju Jak Whan(朱雀丸), Doo Dam Tang(導痰湯), Yin Sin Kuei Sa Dan(引神歸舍丹), Ga Gam Go Bon Dan(加減固本丸), Ryung Ji Go(寧志膏), Jang Won Dan(壯元丹), Tong Ol Tang(通鬱湯). 4. In oriental medicine functional physiology and pathology was significant in differential diagnosis and treatment and in western medicine it was explained organically and psychologically. 5. In western medicine As one of memory disorder Amnesia is divided into psychogenic amnesia and organic amnesia, and organic amnesia is divided into anterograde amnesia and retrograde amnesia and psychogenic amnesia is divided into localized amnesia, generalized amnesia selective amnesia.

Localized amnesia is characterized by a failure to recall events that occurred during a circumscribed period of time. Localized amnesia is the most common type of dissociative amnesia. It is assumed that this is a disorder of memory retrieval. Recent neuroimaing studies reported that posterior cingulate cortex may play a important role in memory(autobiographical) retrieval. The authors reported a case of localized amnesia with mass on left posterior cingulate cortex.

Objectives : We suggest the method of oriental neuropsychiatry treatment about amnesia through herb therapy. Methods : We investigate cause of disease, component of herbs about amnesia with classic current oriental medicine books. Results : Amnesia is due to simsinbulgyo(心腎不交), biwieyangher(脾胃陽虛), dammisimgyoo(痰迷心竅), emotional damage(七情所傷), extravasated blood(瘀血), deficiency of kidney (腎虛). There is 138 kind of herbs are used in our study that we find out that most frequently used herb is ginseng(人蔘). Heart meridian is the highest use in the all meridians. Sungon(性溫) is the highest use in the all kimi(氣味) Conclusions : We could confirm that herbs of amnesia treatment was related to the three vital organs(臟) named of spleen(脾), lung(肺), kidney(腎).

Dissociative amnesia is caused by psychologic disagreement except organic brain disorder, intoxication, severe fatigue and occurred by not recalling saved information. Recently we experienced a 19 year-old woman who had a sudden onset of dissociative amnesia and whose condition was improved through Oriental medical treatment. This case study illustrates what the manifestations of dissociative amnesia is and how dissociative amnesia symptomatology emerged.

In this present study, we investigated the effects of red ginseng extract and its active constituents - Rbl , Re, Rgl on cycloheximide (CXM)-induced amnesia in the passive avoidance task in rats. Red ginseng water extract at 0.05-0.5 g/kg could improve CXM-induced amnesia in rats, Furthermore, the recovery effect of Rbl at 10 mghg administered 30 min before training trial from CXM-induced amnesia was better than those of Rbl administered other time before or after training trial. Rbl at 0.001-0.1 mghg could significantly improve CXM-induced amnesia and at 1 mghg completely augmented, but at 10 mghg its improving effect slightly weakened. Rgl and Re at 0.3-10 mghg could significantly improve CXM-induced amnesia and Rgl at 10 mg/kg completely avgmented. On the other hand, Rbl at 10 mghg could prolong the step through latencies in the training trial. These results suggest the beneficial effect of red ginseng extract on CXM-induced amnesia in rats could mainly due to the contribution of its active constituents - Rbl, Re, Rgl. The improving effect of Rbl on CXM-induced amnesia was best among the three active constituents. But the reduction in the improving effect of Rbl at 10 mg/kg might be due to the decrease in motor activity and attention to the passive avoidance task.

Midazolam is known to produce sedation as well as amnesia. Many articles reported about anterograde amnesia, but it is rare that articles about retrograde amnesia. The 61-year-old female patient (64 kg, 154 cm, ASA physical status I) was administered 3.02 mg (0.047 mg/kg) of midazolam during 2 hours. The patient's Modified Observer's Assesment of Alertness/Sedation Scale was 4. The patient who had been consciously sedated with midazolam, exhibited profound amnesia, both anterograde and retrograde after implantation. The patient's memory restoration was begun after 6 hours.

Objective : Transient anterograde amnesia is occasionally observed in a number of conditions, including migraine, focal ischemia, venous flow abnormalities, and after general anesthesia. The inhalation anesthetic, isoflurane, is known to induce transient anterograde amnesia. We examined the involvement of brain-derived neurotrophic factor (BDNF) and its receptor tyrosine kinase B (TrkB) in the underlying mechanisms of the isoflurane-induced transient anterograde amnesia. Methods : Adult male Sprague-Dawley rats were divided into three groups : the control group, the 10 minutes after recovery from isoflurane anesthesia group, and the 2 hours after recovery from isoflurane anesthesia group (n=8 in each group). The rats in the isoflurane-exposed groups were anesthetized with 1.2% isoflurane in 75% nitrous oxide and 25% oxygen for 2 hours in a Plexiglas anesthetizing chamber. Short-term memory was determined using the step-down avoidance task. BDNF and TrkB expressions in the hippocampus were evaluated by immunofluorescence staining and western blot analysis. Results : Latency in the step-down avoidance task was decreased 10 minutes after recovery from isoflurane anesthesia, whereas it recovered to the control level 2 hours after isoflurane anesthesia. The expressions of BDNF and TrkB in the hippocampus were decreased immediately after isoflurane anesthesia but were increased 2 hours after isoflurane anesthesia. Conclusion : In this study, isoflurane anesthesia induced transient anterograde amnesia, and the expressions of BDNF and TrkB in the hippocampus might be involved in the underlying mechanisms of this transient anterograde amnesia.

Dissociative disorder is a psychiatric disorder characterized by a sudden loss of memory, but which has no organic disease or explanation. It usually occurs after heavy psychosocial stress or traumatic experience. A transient cerebral ischemic attack (TIA) is an acute episode of temporary and focal loss of cerebral function of vascular origin. TIAs are rapid in onset; symptoms reach their maximal manifestation in fewer than 5 minutes. Manifestations are of variable duration and typically last 2-15 minutes(rarely as long as 24 h). Most TIA durations are less than 1 hour. Of concern is the careful detection of changes in behavior, speech, gait, memory, movement, and vision. TIAs are uncommon in persons younger than 60 years. I treat 6 cases of Sudden Temporary Amnesia Patients with oriental medicine and they are improved. All of them had amnesia for $6{\sim}10\;hours$. During that time, they show behavioral changes and they are not on the state of unconsciousness. After recovery, they also forget what happen at the time. they have some emotional reason too. In conclusion, 4 cases of them belong to dissociative disorder and 2 other cases, TIA.

Dissociative disorder is a breakdown of one's perception of one's surroundings, memory, identity, or consciousness. Dissociative amnesia is too wide-ranged to define itself of simple amnesia or oblivion. In this case, a 62 years old female diagnosed as Geonmang due to Dameobijo. The patient was treated with mainly Gungsindodam-tang and Gamisachil-tang. Clinical symptoms and general conditions are improved after treatment and more extensive researches are needed.
