What is the Difference between dysarthria and expressive aphasia?
Both dysarthria and aphasia are abnormalities of speech. The chain of speech and abnormalities are as follow:
i. Hearing
ii. Understanding -- Aphasia
iii. Thought & word finding -- Aphasia
iv. Voice production
v. Articulation -- Dysarthria
Aphasia refers to the abnormalities in understanding, thought and word finding.
Dysarthria refers to the difficulties in speech at any level such as breathing, vocal cord, larynx, palate, tongue and lips.
The common types of aphasia are Wernicke's aphasia and Broca's aphasia.
Wernicke's area (Broadmann's area 22) in cerebral cortex receives visual input from occipital lobe and auditory input from temporal lobe, it permits the understanding of spoken and written language and enable a person to interprete it. Destruction of Wernicke's area in dominant hemisphere cause receptive aphasia. The patient is unaware of the speech by others and also himself. So, he speaks long and meaningless speech. Since the Broca's area is intact, he can produce smooth speech.
Broca's area (Broadmann area 44, 45) in cerebral cortex is motor speech area. It is connected to the Wernicke's area by arcuate fasciculus. It receives impuls from Wernicke's area and converted it into the motor command and sends to cerebral cortex to be converted into action of muscles involved in speech.If destructed, the patient retains the ability to think. The patient speaks short but meaningful speech with great effort. The sentence is not complete. This is expressive aphasia.
For dysarthria, lesions of upper motor neuron, lower motor neuron, basal ganglia, cerebellum or extrapyramidal system leads to disturbance of the intergration of speech production and the speech rhythm. The speech of the patient is not clear but very complete and meaningful. Patient can interprete other's speech and respond to it correctly.
Can an asymptomatic migraine cause aphasia?
A Migraine without the headache stage is called Acephalgic Migraine. Asymptomatic means without symptoms. An Acephalgic Migraine may include the symptom of aphasia, however since asymptomatic means without symptoms, that answer would be no, it does not.
What determines the severity of aphasia?
The severity of aphasia is related to a number of factors, including the severity of the condition that brought it about, general overall health, age at onset, and numerous personal characteristics that relate to motivation.
Can expressive aphasia be caused by anything other than a stroke?
Yes, expressive aphaisa can be caused by different types of neurological disorders e.g. Traumatic Brain Injury, Multiple Sclerosis, although it is most commonly seen following stroke.
Regular practice of small words beginning.
after few days practice more complex words.
Is aphasia a traumatic brain injury?
No; it is a brain-based language disorder that may be caused by a brain injury.
Is there a relationship between sleep apnea and aphasia?
No because the causes of the two are unrelated. Sleep apnoea is a problem with your breathing. It happens at intervals very briefly while you lie in bed and is most usually due a physical not a mental over relaxation of the muscles of the soft palate in your throat because the muscles sag and obstruct the passage of air or else very occasionally a consequence of brief interruption of command reception from respiratory brain stem, but only ever while brain is partly resting during your sleep. It is never associated with neural communication while brain is fully awake.
The cause of Aphasia, (which means a complete absence of previously acquired ability to speak a language), is related by a long term neuron loss from the dominant cerebral hemisphere effective during periods both when you are awake and asleep. This is most usually due to brain damage such as after a stroke or head injury which is linked to the brain order that affects your ability to speak and write. Aphasia is sometimes linked to Alexia (word blindness) or Agraphia (writing difficulty), not to any kind of temporary nor permanent breathing disorder
What are the kinds of aphasia?
Aphasia is an impairment in the comprehension and/or production of language. The two main headings are fluent and non-fluent aphasia.
This is an addition to the above-mentioned answer.
Aphasia is caused by a brain injury, as may occur during a traumatic accident or when the brain is deprived of oxygen during a stroke. It may also be caused by a brain tumor, a disease such as Alzheimer's.
Aphasia is a language impairment caused by neurologic damage, usually to the left hemisphere of the brain. It can effect how a person comprehends language (receptive) or uses language (expression). It can also cause a "global" impairment of language (effecting both reception and expression). Aphasia is commonly diagnosed in the early stages of recovery after a stroke or a head injury. People typically receive speech therapy to improve their language skills. Prognosis for improvement varies based on type and location of brain injury and severity of lesion.
Can seizures cause wernicke's aphasia?
Epilepsy can sometimes cause episodes of aphasia, but it is a rare thing.
Can a flashback cause aphasia?
Well it depends on what is meant by the term "flashback." And aphasia is in a whole different camp than a flashback. Aphasia.org explains much about aphasia. Aphasia is often a SYMPTOM rather than a result of something. Aphasia means disordered communication with the world, and difficulty or inability to share with other people, their thoughts by using words, about ideas and concepts. However, cognitive abilities are often intact.
What drugs can be used to treat aphasia?
To date, no pharmacological treatments for aphasia have proven effective, although a number of drugs (dopaminergic, cholinergic, and neurotrophic) continue to be investigated, usually in conjunction with behavioral treatments for aphasia.
Instead of drugs, many aphasia patients benefit from intensive speech therapy.
Do people with aphasia use sign language?
Some people with expressive aphasia, use sign language successfully. Others with aphasia lack the cognitive capacity to make use of sign language.
That said, strictly speaking, aphasia is a communications disorder. Most patients have not lost cognitive ability, unless the aphasia was attended by another brain injury that resulted in it.
How is expressive aphasia characterized?
The medical condition expressive aphasia is characterized by an inability to produce language in verbal or written forms. The most common cause of expressive aphasia is a stroke.
Can a heart attack cause aphasia?
Yes, it can. Aphasia is a speech and language disability resulting from brain damage. "Heart attack" can deprive the brain of oxygen; oxygen deprivation can damage brain cells; the damage can cause aphasia.
What are the pain assessment scale use for patients with expressive and receptive aphasia?
A numeric scale is appropriate because the patient/client can indicate, by pointing or raising fingers, to indicate his/her current pain level. Clients with motor aphasia cannot express themselves verbally or in writing.
Definition of childhood aphasia?
Aphasia describes the sudden loss of ability to speak, meaning the ability was once there, and now it is gone.
What is the difference between receptive and expressive aphasia?
Receptive: Can't understand speech. Expressive: Can't produce speech (can't speak)
Yes; aphasia is a neurogenic communicative disorder caused by damage to the language areas of the brain.
