About Aphasia Symptoms Speech loss is not the only symptom.


Have you ever heard of a disorder called aphasia?

This is common as we get older, we can't get the words out.
There it is! That!"
This is completely different from the kind of language in which the words become "gibberish" (a kind of gibberish).

Aphasia is a disorder in which a person has trouble with the language center of the brain and cannot handle language well.

Aphasia is a disorder in which a person has trouble with the language center of the brain.

  • Words do not come out.
  • Words for things that are not what you see
  • Not understanding the meaning of words heard
  • Words become inaudible
  • Can read words but cannot understand them
  • I read the text differently than it is opened.
  • I lose the ability to write out the letters
  • Letters do not come to mind
  • etc.

Let's take a closer look at the symptoms of aphasia.

Impairment in Talking

First, let's look at the most commonly associated with aphasia, which is an impairment in speaking.

  • difficulty in evoking words
  • Word-finding illusion
  • Phonetic digrammatics
  • neologisms
  • ungrammaticality
  • Jargon
  • Anatomy

So what are the symptoms of each?

Difficulty in evoking words

Inability to produce words

word confusion

Words come out that are not what they are intended to be.

Phonological complex

Choosing the wrong words and sounds


Speak non-existent words


Inability to speak the language correctly


The entire sentence being spoken becomes unintelligible.


Sentences become awkward

Impairment in listening

Aphasia also affects listening to speech.
The language area is damaged, so the meaning of words and other information is lost.

Let's take a look at such obstacles to listening to speech.

  • deafness of speech and sound
  • Phonological Matching Disorder
  • Deafness in word form
  • deafness in the meaning of words

So what are the symptoms of each?

Word deafness

Inability to correctly distinguish the sounds of words

Phonological Matching Disorder

Unsure which phoneme the heard word sound corresponds to

word-form deafness

The word you hear is the first word you have ever heard.

Word sense deafness

The heard word itself feels familiar, but the meaning is not clear.

Word deafness may be similar to sensorineural hearing loss in sensation.

Other symptoms can be like not being able to connect the sounds you hear to the words or sounds you have in your drawer in the first place.

Impairment in reading and writing

Impairment is also seen in writing.
Both auditory and visual information is ultimately processed and organized by the brain.

There is trouble in the language area that processes this information, so it cannot be processed properly.

Let's take a look at what kind of disorders are seen in reading and writing.


  • reading with the letter "diachronic" (i.e., "spelling")
  • Word segment confusion


  • Word formation
  • Phonetic illusion
  • Jargon loss
  • Compositional apraxia
  • Aphasia (a loss of speech)

Let's take a look at each of these symptoms.

Illusory reading of letters

Misreading a single letter unit

Word-final confusion

Misreading whole words (mainly Kanji)

word formation confusion

Writing words that are different from what you want to write

Phonetic confusion

Wrong choice or arrangement of kana

Jargon loss of writing

Write letters that are unintelligible

Compositional alexithymia

Know the correct letter form, but when writing, the form is broken


I understand the letters themselves, but I don't know how to write them.

Normally, we can write and read letters without being particularly conscious of it, but
The brain subconsciously matches the shapes and sounds of letters and traces them to mouth and hand movements for speaking and writing.

When that tracing fails, writing, reading, and speaking become impaired.
