COmmunication Disorders

an acquired neurological impairments of processiong for receptive and/or expressive language

• Lesion often in temporoparietal lobe of dominant hemisphere
• word output is functional
• speech production is functional
• "EMPTY SPEECH" or jargon
• paraphasis (substitution of incorrect words)

• Lesion found at the posterior region of the superior temporal gyrus
• Major fluent aphasia
• comprehension (reading/auditory) impairment
• paraphasias
• severe impairment with repetition
• good articulation
• impaired writing

• lesion of the supramarginal gyru and arcuate fasciculus
• major fluent aphasia
• severe impairment with repetition
• good comprehension
• speech interrupted by word-finding difficulties
• reading intact
• writing impaired

• Lesion of angular gyrus
• minor fluent aphasia
• word finding difficulties with writing and speech
• functional comprehension
• speech can seem empty; words regarding content are dropped

• Lesion often in frontal region of the dominant hemisphere
• poor word output
• increase effort for producing speech
• poor articulation
• dysprosodic speech (bad pitch or timing)
• content of speech is present, but syntactical words are impaired

• major non-fluent aphasia
• most common
• lesions of the 3rd convolution of frontal lobe
• intact auditory and reading comprehension
• impaired repetition and naming skills
• frequent frustration regarding language skill errors

• major non-fluent aphasia
• lesion of frontal, temporal, and parietal lobes
• comphension (reading and auditory) is severely impaired
• impaired naming and writing skills
• impaired repetition skills

a non-dysarthric and non-aphasic impairment of prosody and articulation of speech

a motor disorder of speech that caused by an upper motor neuron lesion that affects the muscles that are used to articulate words and sounds
