Amnesia

• Amnesia can be referred to as the loss of
  memories, like facts, information and
  experiences. However having no sense about
  yourself is a common plot idea in movies and
  television, real-life amnesia usually doesn't
  cause a loss of self-identity.Instead, people
  with amnesia are usually brilliant and know who
  they are, but can have trouble learning new
  information and forming new memories.Amnesia
  can be caused by damage to areas of the brain
  which are important for memory processing. Unlike
  some moment of memory loss (transient global
  amnesia), amnesia can be permanent.There's no
  single treatment available for treating amnesia,
  but some of the techniques for increasing memory
  and psychological support can help people with
  amnesia and their families to cope.

Causes of Amnesia

• Possible causes of neurological amnesia include
• Stroke
• Encephalitis (Brain inflammation) as a result of
  infection with a virus like herpes simplex virus,
  as an autoimmune reaction to cancer somewhere
  else in the body (paraneoplastic limbic
  encephalitis), or as an autoimmune reaction in
  the absence of cancer
• Deficiency of adequate oxygen in the brain, for
  example, from heart attack, respiratory distress
  or carbon monoxide poisoning
• Long-term consumption of alcohol further leads to
  thiamin (vitamin B-1) deficiency
  (Wernicke-Korsakoff syndrome)
• Tumors in areas of the brain that control memory
• Degenerative brain diseases, such as Alzheimer's
  disease and other forms of dementia
• Seizures
• Certain medications, such as benzodiazepines

Risk Factors

• The chance of developing amnesia might increase
  if you've experienced
• Brain surgery, head injury or trauma
• Stroke
• Alcohol abuse
• Seizures
• Complications of AmnesiaIt will not be
  possible to recover all the lost memories. Some
  people with severe memory problems need to live
  in a supervised situation or extended-care
  facility.

Symptoms of Amnesia

• The two main features of amnesia are
• Impaired ability to learn new information
  following the onset of amnesia (anterograde
  amnesia)
• Impaired ability to recall past events and
  previously familiar information (retrograde
  amnesia)Most people who are suffering with
  amnesia have problems with short-term memory
  they can't retain new information. Recent
  memories are most likely to be lost, while more
  remote or deeply ingrained memories can be
  spared.An isolated memory loss does not
  eventually affect a person's intelligence,
  general knowledge, awareness, attention span,
  judgment, personality or identity.

Symptoms of Amnesia

• People suffering with amnesia normally can
  understand written and spoken words and can learn
  skills such as bike riding or piano playing. They
  may understand that they have a memory
  disorder.Amnesia isn't the same as dementia.
  Dementia can also involve memory loss, but it
  also includes other significant cognitive
  problems that further leads to a decline in the
  ability to carry out daily activities.A pattern
  of forgetfulness is also a common symptom of mild
  cognitive impairment (MCI), but the memory and
  other cognitive problems in MCI aren't as severe
  as those experienced in dementia.
