Aphasia is a language disorder acquired secondary to an injury in the part of the brain responsible for language. Aphasia is very often caused by injury to the left hemisphere of the brain. Aphasia affects language comprehension, language production, reading and writing. There are several types of aphasia; the main divisions are fluent and non-fluent aphasia. The severity of aphasia depends on the extent and the location of the brain injury.
Signs and symptoms vary from individual to individual. It is not necessary to have all of the characteristics above to be diagnosed with aphasia. Individuals on the higher spectrum of functionality may be able to formulate complete sentences but experience slight difficulty with auditory comprehension and word finding. Individuals on the lower spectrum of functionality may be “global”, unable to comprehend and speak at all. Aphasia may co-exist with other disorders such as apraxia of speech or dysarthria.

- Head tumor

Apraxia of speech is a neurogenic motor- speech disorder secondary to damage to the parts of the brain; responsible for motor programming and sequencing. Apraxia of speech does not include muscular weakness, coordination or sensory loss. Facial muscles move but they have difficulty executing the program necessary for appropriate movements/articulatory postures. Individuals with apraxia of speech know what they want to say but have difficulty saying it.
Dysarthria is a neurogenic motor speech disorder resulting from muscular weakness of the tongue, lips, soft palate, larynx or respiratory muscles . Individuals with dysarthria may exhibit abnormalities in strength, speed, range, tone and accuracy of muscular movements. Dysarthria may affect speech production, voice, respiration and prosody (melody of speech). There are different types of dysarthria. Dysarthria may co-exist with other disorders like apraxia of speech or aphasia (acquired language disorder).
