Amnesia (Versi Bahasa Inggris)

Amnesia

From Wikipedia, the free encyclopedia








Amnesia (from Greek Ἀμνησία) is a short term memory condition in which memory is disturbed. In simple terms it is the loss of memory. The causes of amnesia are organic or functional. Organic causes include damage to the brain, through trauma or disease, or use of certain (generally sedative) drugs. Functional causes are psychological factors, such as defense mechanisms. Hysterical post-traumatic amnesia is an example of this. Amnesia may also be spontaneous, in the case of transient global amnesia.[1] This global type of amnesia is more common in middle-aged to elderly people, particularly males, and usually lasts less than 24 hours.

Another effect of amnesia is the inability to imagine the future. A recent study published online in the Proceedings of the National Academy of Sciences shows that amnesiacs with damaged hippocampus[2] This is because when a normal human being imagines the future, they use their past experiences to construct a possible scenario. For example, a person who would try to imagine what would happen at a party that would occur in the near future would use their past experience at parties to help construct the event. cannot imagine the future.

Forms of amnesia

  • In anterograde amnesia, new events contained in the immediate memory are not transferred to the permanent as long-term memory.
  • Retrograde amnesia is the distinct inability to recall some memory or memories of the past, beyond ordinary forgetfulness.

The terms are used to categorize patterns of symptoms, rather than to indicate a particular cause or etiology. Both categories of amnesia can occur together in the same patient, and commonly result from drug effects or damage to the brain regions most closely associated with episodic/declarative memory: the medial temporal lobes and especially the hippocampus.

An example of mixed retrograde and anterograde amnesia may be a motorcyclist unable to recall driving his motorbike prior to his head injury (retrograde amnesia), nor can he recall the hospital ward where he is told he had conversations with family over the next two days (anterograde amnesia).

The effects of amnesia can last long after the condition has passed; many sufferers claim that amnesia changes from a neurological condition to a psychological condition, whereby the patient loses confidence and faith in their own memory and accounts of past events.

Types and causes of amnesia

Post-traumatic amnesia is generally due to a head injury (e.g. a fall, a knock on the head). Traumatic amnesia is often transient, but may be permanent of either anterograde, retrograde, or mixed type. The extent of the period covered by the amnesia is related to the degree of injury and may give an indication of the prognosis for recovery of other functions. Mild trauma, such as a car accident that results in no more than mild whiplash, might cause the occupant of a car to have no memory of the moments just before the accident due to a brief interruption in the short/long-term memory transfer mechanism. The sufferer may also lose knowledge of who people are, they may remember events, but will not remember faces of them.

  • Dissociative amnesia results from a psychological cause as opposed to direct damage to the brain caused by head injury, physical trauma or disease, which is known as organic amnesia. Dissociative amnesia can include:
  • Repressed memory refers to the inability to recall information, usually about stressful or traumatic events in persons' lives, such as a violent attack or rape. The memory is stored in long term memory, but access to it is impaired because of psychological defense mechanisms. Persons retain the capacity to learn new information and there may be some later partial or complete recovery of memory. This contrasts with e.g. anterograde amnesia caused by amnestics such as benzodiazepines or alcohol, where an experience was prevented from being transferred from temporary to permanent memory storage: it will never be recovered, because it was never stored in the first place. Formerly known as "Psychogenic Amnesia"
  • Dissociative Fugue (formerly Psychogenic Fugue) is also known as fugue state. It is caused by psychological trauma and is usually temporary, unresolved and therefore may return. The Merck Manual defines it as "one or more episodes of amnesia in which the inability to recall some or all of one's past and either the loss of one's identity or the formation of a new identity occur with sudden, unexpected, purposeful travel away from home." [3] While popular in fiction, it is extremely rare.
  • Posthypnotic amnesia is where events during hypnosis are forgotten, or where past memories are unable to be recalled.
  • Childhood amnesia (also known as infantile amnesia) is the common inability to remember events from one's own childhood. Sigmund Freud attributed this to sexual repression, while others have theorised that this may be due to language development or immature parts of the brain.
  • Transient global amnesia is a well-described medical and clinical phenomenon. This form of amnesia is distinct in that abnormalities in the hippocampus can sometimes be visualized using a special form of magnetic resonance imaging of the brain known as diffusion-weighted imaging (DWI). Symptoms typically last for less than a day and there is often no clear precipitating factor nor any other neurological deficits. The cause of this syndrome is not clear, hypotheses include transient reduced blood flow, possible seizure or an atypical type of migraine. Patients are typically amnestic of events more than a few minutes in the past, though immediate recall is usually preserved.
  • Source amnesia is a memory disorder in which someone can recall certain information, but they do not know where or how they obtained the information.
  • Blackout phenomenon can be caused by excessive short-term alcohol consumption, with the amnesia being of the anterograde type.
  • Korsakoff's syndrome can result from long-term alcoholism or malnutrition. It is caused by brain damage due to a Vitamin B1 deficiency and will be progressive if alcohol intake and nutrition pattern are not modified. Other neurological problems are likely to be present in combination with this type of Amnesia. Korsakoff's syndrome is also known to be connected with confabulation.
  • Drug-induced amnesia is intentionally caused by injection of an amnesiac drug to help a patient forget surgery or medical procedures, particularly those which are not performed under full anesthesia, or which are likely to be particularly traumatic. Such drugs are also referred to as "premedicants". Most commonly a 2'-halogenated benzodiazepine such as midazolam or flunitrazepam is the drug of choice, although other strongly amnestic drugs such as propofol or scopolamine may also be used for this application. Memories of the short time frame in which the procedure was performed are permanently lost or at least substantially reduced, but once the drug wears off, memory is no longer affected.

Amnesia in fiction

Amnesia is prevalent in many works of fiction. Global amnesia is a common motif in fiction despite being extraordinarily rare in reality. In movies and television, particularly sitcoms and soap operas, it is often depicted that a second hit to the head (similar to the first one) cures the amnesia. When one has amnesia in fiction, it is often followed by a melodramatic "Who am I? What am I? Where am I?", or sometimes, "[name of amnesiac]? Who's [name of amnesiac]?" Amnesia has also been prominently used as a plot device in many video games to help explain why the main character (and in essence the player) knows very little about the world he is in. In reality, however, repeat concussions may cause cumulative deficits including cognitive problems, and in extremely rare cases may even cause deadly swelling of the brainsecond-impact syndrome. associated with

Amnesia
Klasifikasi & sumber eksternal




Amnesia (dari Bahasa Yunani Ἀμνησία) adalah kondisi terganggunya daya ingat. Penyebab amnesia dapat berupa organik atau fungsional. Penyebab organik dapat berupa kerusakan otak, akibat trauma atau penyakit, atau penggunaan obat-obatan (biasanya yang bersifat sedatif). Penyebab fungsional adalah faktor psikologis, seperti halnya mekanisme pertahanan ego. Amnesia dapat pula terjadi secara spontan, seperti terjadi pada transient global amnesia[1]. Jenis amnesia global ini umum terjadi mulai usia pertengahan sampai usia tua, terutama pada pria, dan biasanya berlangsung kurang dari 24 jam.

Dampak lain dari amnesia adalah ketidakmampuan membayangkan masa depan. Penelitian terakhir yang dipublikasikan dalam jaringan di Proceedings of the National Academy of Sciences menunjukkan bahwa amnesia dengan kerusakan pada hippocampus tidak dapat membayangkan masa depan[2]. Hal ini terjadi karena bila seorang yang normal membayangkan masa depan, mereka menggunakan pengalaman masa lalu untuk mengkonstruksi skenario yang mungkin dihadapi. Sebagai contoh, seseorang yang mencoba membayangkan apa yang akan terjadi dalam pesta yang hendak didatanginya akan menggunakan pengalaman pesta sebelumnya untuk membantu mengkonstruksi kejadian di masa depan.

Bentuk amnesia

  • Anterograde amnesia: kejadian baru dalam ingatan jangka pendek tidak ditransfer ke ingatan jangka panjang yang permanen. Penderitanya tidak akan bisa mengingat apapun yang terjadi setelah munculnya amnesia ini walaupun baru berlalu sesaat.
  • Retrograde amnesia: ketidakmampuan memunculkan kembali ingatan masa lalu yang lebih dari peristiwa lupa biasa.

Kedua kategori amnesia tersebut dapat muncul bersamaan pada pasien yang sama. Contohnya seperti pada pengendara sepeda motor yang tidak mengingat akan pergi kemana dia sebelum tabrakan (retrograde amnesia), juga melupakan tentang kejadian di rumah sakit dua hari setelahnya (anterograde amnesia).

Susahnya...

Siapa sangka kehidupan bisa berubah dalam hitungan detik....

Awalnya... kehidupan ku penuh dengan kesibukan yang padat... hari demi hari penuh dengan inspirasi, canda tawa dan kerja yang aktif...tiada hari tanpa kesibukan sampai-sampai untuk merasakan hari libur tanpa kegiatan sulit banget....( kata ibu ku yang dulu sulit banget buat ketemu aku...heheheheh ) dengan kepandaian menari tari tradisional... sebagai penyanyi kotaann MC dalam acara metting ato pesta2, pekerja kantor dan wiraswasta kecil-kecilan rasanya hari ku terasa penuh dengan aktifitas yang membuat ibuku harus bersabar buat sekedar pengen menanyakan kabar ku...heheheheh

Namun semua berubah dalam hitungan detik.. ketika sebuah kecelakaan kecil telah menghilangkan seluruh memory ingatan ku...dan memulai mengenal diriku dari nol lagi... kata dokter yang telah mengobservasi ku dibilang "amnesia"...yang semula sering di lihat oleh keluarga ku hanya cerita sinetron.. ternyata benar terjadi n hadir di tengah-tengah kami... semula setelah kecelakaaan itu aku biasa aja.. tapi begitu baru tidur kemudian aku terbangun tak ingat apa2 hanya bingung tak mengerti.. bahkan saat ini pun aku tak ingat kejadian2 itu....semua ku peroleh dari cerita keluarga ku bagaimana mereka berbesar hati menghadapi semua peristiwa itu...terlalu sulit.. mereka tidak siap menerima kenyataaan si kutu loncat tiba-tiba gugur....

Masa-masa yang menyulitkan itu telah lambat laun terlewati.. dan aku paling tidak sudah jauh lebih baik perkembangannya...sudah bisa mengenal komputer, internetan, dan mengelola usaha kecil-kecilan ku dan yang lebih hebat lagi dah menikah n memiliki 1 anak yang lagi lucu-lucunya...... lambat laun dengan kesabaran suami, keluarga besar n sahabat serta kerabat dekat ku aku bisa menyemangati diriku buat belajar mengejar ketinggalan ku...dah mulai buka riasan kecil-kecilan, dan rada luwes masak walau kadang kurang asin heheheh, dah bisa merawat anakku walau banyak dibantu sana-sini..hehehe.. cuman tak mengecilkan hatiku untuk lebih bisa berkembang lagi bahkan ada beberapa yang menawari buat kerja kantoran lagi...alhamdulillah...

Namun susahnya.......saat ini aku sering bertemu dengan mereka-mereka ato orang-orang yang dimasa laluku sangat mengenal aku.. dan capeknya aku tak mengenal mereka sama sekali... untuk menyenangkan hati n membuatnya nyaman aku berusaha seakrab mungkin menerima mereka... jujur ini sangat-sangat sulit ku lakukan... karena aku dihadapkan pada dilema jika aku diam maka kesan nya aku sombong padahal jujur aku gak ingat mereka sama sekali...uuu susah banget....jelasin ke mereka, yang lebih susah lagi kalo mereka dah membahas hal dimasa lalu ku yang tak ku pahami n ku mengerti sedikit pun... weleh... bisa capek aku berusaha nyambungin omongan...heheheheh karena disisi lain aku gak ingin mereka tersinggung ato kecewa dengan pengakuan ku kalo aku gak inget semua itu tapi disisi lain takut mereka juga gak percaya kalo aku bener2 lupppaaaa....

Tapi apa daya ku aku harus lebih suabbaarrrr.... memotivasi diri untuk menjadi diriku yang baru ini... karena menurut banyak pihak ada beberapa hal yang tidak mereka dapat didiriku saat ini, pribadi ku sedikit banyak berubah.. ..entah apa yang mereka maksudkan perubahan itu karena aku gak bisa mengingatnya...

Jadi harapan ku.. buat semua ato siapa aja yang pernah ato sedang mengalami hal seperti aku.. yang ingin ku sampaikan hanya bersabarlah.. emang susah buangett....semua memang butuh waktu dan butuh motivasi serta kesadaran dari orang sekitar kalo perkembangan menuju normal itu gak semudah membalikkan telapak tangan....tapi butuh doa dan dorongan ....

Semoga bisa jadi renungan....
