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 RA once the patient has died. There are some aspects essential to the patient that remain unaffected by RA. 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 ones life experiences, is impaired.Another real life problem with RA is malingering, which is conceived as the rational 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 RA 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 rather complex one. Spontaneous recovery
When someone has RA, their memory cannot be recovered by simply being informed about their personal experiences and their identity. This is called reminder effect or reminder treatment.
Papular purpuric gloves and socks syndrome is a cutaneous condition characterized by pruritus, edema, and erythema of the hands and feet, occurring primarily in teenagers and young adults. : 401 An association with parvovirus B19 has been described. It was discovered by a duo of medical students; Kishorkumar Osman and Sulaiman Saloojee, during a ward round. See also
