Testing for<unk>  As previously mentioned,<unk>  can affect people's memories in different degrees, but testing is required to help determine if someone is experiencing<unk> . Several tests exist, for example, testing for factual knowledge such as known public events. A problem with this form of testing is that people generally differ in their knowledge of such subjects. The tests also have to be changed regularly to adapt to the period of time patients have been alive, and include questions about autobiographical events that<unk> nge in amount of detail. Due to the nature of the information being tested, it is often difficult to verify the accuracy of the memories being recalled, especially if they are from a distant past. One way to confirm information is by consulting close family members or caregivers. Another problem that arises is that this type of testing can result in a significant amount of data that needs to be processed and confirmed. Other ways to test someone is via autobiographical knowledge using the Autobiographical Memory Interview (AMI). A test that comprises names of relatives, personal information, and job history. The AMI was created by Kopelman, Wilson, and Baddeley (1990). This information could help determine if someone is experiencing<unk>  and the degree of memory affected. Some researchers have found that the time interval after the head injury occurred did not seem to matter. The effect of the memory loss was the same no matter how long it had been after from the injury. Brain abnormalities can be measured using magnetic resonance imaging (MRI), computed tomography scan (CT) and electroencephalography (EEG), which can provide detailed information about specific brain structures. In many cases, an autopsy helps identify the exact brain region affected and the extent of the damage that caused<unk>  once the patient has died. There are some aspects essential to the patient that remain unaffected by<unk> . In many patients, their personality remains the same. Also, semantic memory, that is general knowledge about the world, is usually unaffected. However, episodic memory, which refers to one's life experiences, is impaired. Another real life problem with<unk>  is malingering, which is conceived as the<unk> tional output of a neurologically normal brain aiming at the surreptitious achievement of a well identified gain. Since it is common for people who have committed a crime to report having<unk>  for that specific event in order to avoid their punishment, the legal system has pushed for the creation of a standardized test of amnesia. However, since most cases differ in onset, duration, and content forgotten, this task has shown to be a<unk> ther complex one. Spontaneous recovery When someone is suffering from<unk> , their memory cannot be recovered by simply being informed about their personal experiences and their identity. This is called reminder effect or reminder treatment. The reminder effect consists of re-exposing the patient to past personal information, which cannot reverse<unk> . Thus, reminding the patient about details of their life has no scientific bearings on recovering memory. Fortunately, memory can be and usually is recovered due to spontaneous recovery and plasticity.
