What is Aphasia?

A neurological language disorder impairing the ability to speak, understand, read, and write.

Causes of Aphasia

Damage to the brain's language centers, often due to stroke, TBI, tumors, or neurodegenerative diseases.

Stroke (CVA)

Blood flow to the brain is blocked, leading to brain cell death.

Traumatic Brain Injury (TBI)

Severe head injuries from accidents, falls or violence.

Study Notes

  • Aphasia is a neurological language disorder, that impairs the ability to speak, understand, read, and write.
  • It is caused by damage to the brain's language-processing areas.
  • Common causes include stroke, traumatic brain injury, brain tumor, or neurodegenerative disease.
  • Intelligence is not impacted by Aphasia, cognition, reasoning and emotion remain normal.

Causes of Aphasia

  • Aphasia occurs when the brain's language centers are damaged, mainly in the left hemisphere.
  • Common causes are neurological, including Stroke (Cerebrovascular Accident, CVA) which is the most common cause, Traumatic Brain Injury (TBI), and Brain Tumors.
  • Neurodegenerative Diseases such as Alzheimer's disease, Frontotemporal dementia, or Primary Progressive Aphasia (PPA) are also causes.
  • Brain Infections like Encephalitis and Meningitis, can damage brain areas responsible for speech, and cause Aphasia.

Types of Aphasia

  • Types are classified depending on the area and extent of brain damage
  • There are three main types:

Expressive Aphasia (Broca's Aphasia)

  • Main feature is struggling to speak fluently but can understand speech.
  • Symptoms include speaking in short phrases or broken sentences, frustration because they know what they want to say but cannot express it.
  • Reading ability is intact, but writing is impaired, speech sounds slow and effortful.

Receptive Aphasia (Wernicke's Aphasia)

  • Main feature is speaking fluently but difficulty understanding speech.
  • Speech is fluent but nonsensical, patients cannot follow conversations, or answer correctly and are unaware of their own speech errors.

Global Aphasia

  • Main feature is severe impairment in both speaking and understanding.
  • Symptoms include only being able to produce a few words or sounds, difficulty understanding speech and is often caused by extensive brain damage such as large stroke.

Symptoms of Aphasia

  • General symptoms include Difficulty finding words, speaking in short or incomplete sentences.
  • Also speaking in long, nonsensical sentences, and Difficulty understanding conversations
  • The person may have Trouble reading and writing

Treatment and Rehabilitation

  • There is no cure.
  • Therapy can help patients regain language skills and learn alternative communication methods
  • Common Treatments include Speech and Language Therapy which helps rebuild speaking, understanding, reading, and writing skills.
  • Communication Aids, such as Gestures, pictures, technology (apps, speech devices), can assist.
  • Practicing Conversation Skills with Family and caregivers plays an important role.
  • Alternative Communication Methods includes writing, drawing, or using gestures instead of speech.

Prognosis

  • Mild cases may recover within months, with therapy.
  • Severe cases recovery can take years or remain permanent.
  • Younger patients recover faster than older individuals.

Conclusion

  • Aphasia affects communication but NOT intelligence.
  • Early intervention, therapy, and strong family support can significantly improve a patient's quality of life.
