Title: 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 Amnesia It 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

Symptoms of Amnesia
  • The two main features of amnesia are
  • Impaired ability to learn new information
    following the onset of amnesia (anterograde
  • 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.
