Aphasia: the symptoms

Depending on the language area, the symptoms differ.

Broca aphasia (due to damage to Broca's area) is characterized mainly by the following symptoms:

  • Arthritic disorders that is to say an impossibility to voluntarily exercise precise movements of the tongue or lips.
  • An understanding of language that is relatively conserved.
  • A reduction of verbal spontaneity and a lack of the word: we speak of aphasia with non fluent speech.
  • A difficulty in naming people or objects: anomie.

Wernicke aphasia (due to damage to the Wernicke area) is characterized mainly by the following symptoms:

  • An absence of articulatory disorder.
  • Understanding disorders are sometimes very important: patients are unable to understand what they read or hear.
  • Difficulties in the repetition of words and sentences.
  • A verbal fluency preserved even exaggerated, with a large verbal flow.
  • Paraphasia, that is, the substitution of a word for a sound, an incorrect word or an unintentional word. The speech of these patients is therefore often incomprehensible (jargon). For example, he can pronounce phonemic paraphasias (bilo instead of pen), or verbal paraphasias (replacing one word with another that does not have the same meaning).
Global aphasia is characterized by the total loss of the ability to understand language, to speak, to read or to write. The damaged brain area is extensive, including the Broca area, the Wernicke area and the supramarginal convolution. The prognosis for language recovery is extremely limited.

Conduction aphasia is characterized mainly by:

  • fluent language.
  • almost no change in the understanding of spoken language.
  • extreme difficulties in repeating words or sentences.

According to some researchers, this aphasia results from damage to the arched beam that connects the Wernicke area to the Broca area.
