This condition involves the inability to learn and recall new information, whereas formed before the trauma memory is not affected.
Anterograde amnesia is usually caused by injury to the brain, particularly the frontal and temporal lobes where the memory or the memory is stored.
The following steps will show you how to diagnose anterograde amnesia:
1. Investigate whether a person had suffered concussion in the head recently.
Collisions that do not result in loss of consciousness still can cause amnesia.
Car crashes, sports accidents, and falls are a common cause of concussion.
2. Investigate other sources of brain damage that can cause anterograde amnesia.
Alzheimer's disease, brain tumors, brain infections such as encephalitis, stroke, or neurodegenerative diseases including those capable of causing damage to the brain.
3. Past history of drug abuse. Hallucinogens like LSD or PCP could complicate the ability to remember.
Alcohol, barbiturates, and benzodiazepines can also cause amnesia.
4. Perform regular blood tests to check for systemic disease.
Examination of lumbar puncture may be needed to get the brain through the spinal fluid if suspected infection of the nervous system.
5. Do some checks, such as computed tomography (CT) scan and magnetic resonance imaging (MRI) as the imaging technique for anterograde amnesia.
EEG is usually performed to observe the electrical activity in the brain. Cerebral angiography to detect a decrease in blood flow to the brain.
This method involves injecting a contrast dye into the carotid or vertebral arteries allowing visible on X-ray.
