Amnesia ppt

When people lose their ability to memorize data they have amnesia. In simple terms, amnesia is the loss of memory. Anterograde amnesia - the patient cannot remember new information. 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.

This helps you give your presentation on DISSOCIATIVE AMNESIA in a conference, a school lecture, a business proposal, in a webinar and business and professional representations. Some people with amnesia have difficulty forming new memories. Recent memories, information that should be stored into short-term memory disappear.

This type of amnesia is often caused by severe brain trauma. With anterograde amnesia , you cannot remember new information, although you can remember information and events that happened prior to your injury. The one main type of amnesia is psychogenic. Organic causes of amnesia may include brain damage through injury, or the use of specific drugs - usually sedative drugs.

Retrospective assessment of post-traumatic amnesia (PTA) must take into account factors other than traumatic brain injury (TBI) which may impact on memory both at the time of injury and subsequent to the injury. These include analgesics, anaesthesia required for surgery, and the development of acute or post-traumatic stress disorder. Memory loss may result from two-sided (bilateral) damage to parts of the brain vital for memory storage, processing, or recall (the limbic system, including the hippocampus in the medial temporal lobe).

Retrograde amnesia refers to an inability to retrieve old memories that occurred before the onset of amnesia. More commonly, retrograde amnesia co-occurs with anterograde amnesia and shows a temporal gradient,. Others can’t recall facts or past experiences. Amnesia refers to the loss of memory.

People with amnesia usually retain knowledge of their own identity, as well as motor skills. Mild memory loss is a normal part of aging. The other is the duration of time of lost consciousness.

Loss of memory of events prior to injury is called retrograde amnesia, while loss of memory following the injury is called anterograde amnesia. There is another form, which I refer to as “Swiss Cheese” amnesia,. Retrospective assessment of the duration of post-traumatic amnesia (PTA) is generally considered a reasonably robust measure of severity of traumatic brain injury (TBI), especially in medicolegal practice.

Indee PTA is often taken as the principal index of severity of TBI, without attention to other relevant phenomena. TGA specifically affects memory function. As mentioned previously, patients can register information, but retentive memory ability is affected dramatically.
