Loss of the ability to make, repeat and understand the language caused by injuries of the Broca’s area and Wernicke’s area. Aphasic confuse words with similar sound, and in the progressive phase they forget the proper names, common nouns, adjectives, verbs and preposition.

There are a lot of causes of aphasia:

  • Cerebral infarctions;
  • Stroke;
  • Cancer;
  • Head injury;
  • Seizures;
  • Brain infections;

Two kinds of aphasics exist:

FLOWING: they are able to say a little quantity to words with a few verbs, prepositions and articles. They have lesions in the frontal lobe in the left hemisphere. They recognize to have this disability;

NOT FLOWING: they are able to say 20 words in a minute, and they can say dictionary words and not. They have lesions in the temporal lobe in the left hemisphere. They don’t recognize to have this disability.

We can have three general kinds of aphasia:

  • Of Wernick, it’s caused by a lesion in the Wernick’s area. It causes difficulty in the comprehension and production of language. They are able to recognize when a person tells them to performe movements as “wake up” but not “What’s your name?”. They do not understand that they are incomprehensible.
  • Of Broca, it’s caused by lesion in the Broca’s area. The comprehension is less damaged than production. This people understand that they are incomprehensible. This kind of diseas can regress but it can also progress leading to “foreign accent syndrome” that brings the people to change their accent;
  • Global, when a person has production, understaning and elaboration deficit.

These people, in most cases, are depressed and frustrated because they recognize their disabilities.
