Childhood Speech Disorders

 

Aphasia: Disturbance of fluency, understanding, word finding, and repetition.

Dysphonia: The volume is abnormal. A disturbance of voice production

Dysarthria: The words are not formed properly with difficulties at different levels - vocal cords, larynx, palate, tongue, and lips.

 

Aphasia

 

History: Family history, personal history, social history, right or left hand, language development

Simple question: name, address, job, and how old you are?

Test understanding:

Yes/no questions: "Is this a chair?"

Simple command: "open your mouth; touch your nose with your right hand"

Complicated commands "use your right hand to touch your nose and then touch your left ear"

Assess word finding ability and naming

^Name all the animals you can think of ̄ - normal 18-22 in 1 minute

Give all the words beginning with a particular letter "f or s", normal −12 in 1 minute

Name familiar objects such as fork, spoon, shoes, etc.

Assess repetition: Repeat a simple phrase "The sky is blue.", then increasingly complicated phrases.

Speech Delay

 

 

Definition & Cause

 

 

Dyslexia

From Greek words:

  dys- difficult; les- word

Have difficulty in using words or language.

Many dyslexics are right brain writing, are often very artistic and creative.

Wernick's area-little brain activity

  Receptive- understanding the meanings

  of words, and string words together to

   form sentence.

Broca's area: high activity

  Expressive, speaking words

Angular syrus: poor activity

  Turns the image of the word into sound

 

 

         Difficulty connecting letters with sounds

         Difficulty dividing words into syllables

         Confusion or reversal of letter and numbers, such as "sing" and "sign"; "left" and "felt"; or "67" and "76"

         Confusion between letters that look similar, such as b and d; and p and q

         Difficulty remembering what has been read

         Difficulty spelling, hand writing

         Difficulty copying words or numbers from the chalkboard or a book

         Difficulty reading aloud

         Difficulty expressing thoughts and ideas verbally or in written form

         Confusion about directions relating to space or time, such as right and left, up and down, early and late, yesterday and tomorrow, months and days

         Difficulty following instructions, rhyming

         Poor self esteem, frustration, giving up
