Alexic anomia is caused by an injury to the brain. Stroke is the most common cause. Some other causes are:
Alexic anomia is more common in older adults. It is also more common in people who have had a transient ischemic attack (TIA), also known as a mini-stroke.
A person with alexic anomia:
- Cannot understand written words
- Can write, but cannot read what someone has written
The doctor will ask about your symptoms and health history. A physical exam will be done. Speech language, and communication tests may be done. This is often enough to make the diagnosis. You may also need to see a doctor who treats the nervous system.
Other tests may be done to find the cause of the alexic anomia.
The cause of alexic anomia will need to be treated.
Speech and language therapy will also be needed to:
- Restore lost skills
- Learn how to use existing skills
- Learn other ways to communicate
There are no guidelines to prevent alexic anomia. It is caused by underlying health problems.
