Aphasia is a communication disorder that affects a person’s ability to speak understand read or write language.

Aphasia can result from stroke brain injury tumors infections or degenerative neurological conditions. This article explains what aphasia is its causes types symptoms and treatment options.
Understanding Aphasia
Aphasia occurs when the brain’s language centers are damaged. These centers are usually located in the left hemisphere of the brain in areas such as Broca’s area and Wernicke’s area. Broca’s area is responsible for speech production while Wernicke’s area is involved in language comprehension. Damage to these areas can disrupt the ability to communicate effectively.
Aphasia is not a disease but a symptom of an underlying condition. It can range from mild to severe depending on the extent of brain damage. While aphasia primarily affects language skills it does not impact intelligence. People with aphasia often know what they want to say but struggle to find the right words or form coherent sentences.

Primary progressive aphasia is a rare form of aphasia that worsens over time. It is caused by neurodegenerative diseases and primarily affects language abilities while other cognitive functions remain relatively intact.
