Pure alexia
Pure Alexia
Pure alexia, also known as Agnosic alexia or Alexia without agraphia (pronounced: pjuːr əˈlɛksiə), is a rare neurological disorder characterized by a loss of the ability to read, while writing ability and verbal language comprehension remain intact.
Etymology
The term "alexia" comes from the Greek words "a" meaning "without" and "lexis" meaning "word". "Pure" is used to differentiate this condition from other types of alexia that involve additional language or cognitive impairments.
Symptoms
Individuals with pure alexia have difficulty reading all types of content, including words, sentences, and even single letters. However, they can still write, speak, and understand spoken language without difficulty. This condition is often associated with Right homonymous hemianopsia, a visual field loss on the right side of the visual field in both eyes.
Causes
Pure alexia is typically caused by damage to the left Occipital lobe of the brain, particularly the areas responsible for processing visual information. This damage can result from a Stroke, Brain tumor, or other neurological conditions.
Treatment
Treatment for pure alexia is usually focused on rehabilitation strategies that aim to improve reading skills. This may involve Speech therapy, Occupational therapy, and the use of assistive technologies.
