Dysarthria occurs when the muscles you use for speech are weak or you have difficulty controlling them. Dysarthria often causes slurred or slow speech that can be difficult to understand.

Is dysarthria a speech or language?

Dysarthria is a motor speech disorder in which the muscles that are used to produce speech are damaged, paralyzed, or weakened. The person with dysarthria cannot control their tongue or voice box and may slur words. There are strategies to improve communication.

How do people with dysarthria communicate?

The person who has dysarthria and their family may need to learn different ways of communicating, such as:

1. Using hand gestures.
2. Writing by hand what you are saying.
3. Using a computer to type out the conversation.
4. Using alphabet boards, if muscles used for writing and typing are also affected.

What are the symptoms of dysarthria?

Symptoms of dysarthria

• slurred, nasal sounding or breathy speech.
• a strained and hoarse voice.
• very loud or quiet speech.
• problems speaking in a regular rhythm, with frequent hesitations.
• gurgly or monotone speech.
• difficulty with tongue and lip movements.
• difficulty swallowing (dysphagia), which may lead to constant drooling.

Does dysarthria affect intelligibility?

Dysarthria can adversely affect intelligibility of speech, naturalness of speech, or both. It is important to note that intelligibility can be normal in some speakers with dysarthria. Dysarthria may also co-occur with other neurogenic language, cognitive, and swallowing disorders.

Is dysarthria a motor speech disorder?

About Dysarthria

Dysarthria happens when you have weak muscles due to brain damage. It is a motor speech disorder and can be mild or severe. Dysarthria can happen with other speech and language problems. You might have trouble getting messages from your brain to your muscles to make them move, called apraxia.

Does dysarthria affect swallowing?

Dysarthria can range from mild (slurring of speech or slightly slower rate of speaking which only slightly impacts communication) to severe (when speech cannot be understood at all). People with dysarthria may also have difficulty with eating, drinking, and swallowing due to muscle weakness or incoordination.

What is the cause of dysarthria?

Dysarthria often causes slurred or slow speech that can be difficult to understand. Common causes of dysarthria include nervous system disorders and conditions that cause facial paralysis or tongue or throat muscle weakness. Certain medications also can cause dysarthria.

Why has my speech become slurred?

Common causes of speech disorders include alcohol or drug poisoning, traumatic brain injury, stroke, and neuromuscular disorders. Neuromuscular disorders that often cause slurred speech include amyotrophic lateral sclerosis (ALS), cerebral palsy, muscular dystrophy, and Parkinson's disease.

Why does a stroke affect speech?

When stroke affects speech, it's often the result of a left hemisphere stroke. This is because the language center of the brain resides in the left hemisphere.

What is the difference between dysphasia and dysarthria?

Definitions. Dysarthria is a speech disorder caused by disturbance of muscular control. Dysphasia (also called aphasia) is an impairment of language. They often co-exist.

Is dysarthria a type of aphasia?

Aphasia and dysarthria are both caused by trauma to the brain, like stroke, brain injury, or a tumor. Aphasia occurs when someone has difficulty comprehending speech, while dysarthria is characterized by difficulty controlling the muscles used for speech.

What causes slurred speech in brain?

It involves damage to a part of the brain known as Broca's area. Broca's area is responsible for speech production. People with Broca's dysphasia have extreme difficulty forming words and sentences, and may speak with difficulty or not at all.

Can nerve damage cause slurred speech?

Disease or injury to the brain or nerves and muscles of the face, tongue, and vocal cords may cause slurred speech.

What part of the brain is affected by dysarthria?

Ataxic dysarthria causes symptoms of slurred speech and poor coordination. This type of dysarthria can occur if a person sustains damage to the cerebellum. The cerebellum is the part of the brain responsible for receiving sensory information and regulating movement.

What part of the brain affects slurred speech?

Damage to a discrete part of the brain in the left frontal lobe (Broca's area) of the language-dominant hemisphere has been shown to significantly affect the use of spontaneous speech and motor speech control. Words may be uttered very slowly and poorly articulated.

What causes slurred speech and difficulty swallowing?

Difficulty swallowing can be related to infections of the upper airway or to neurological problems that impair the swallowing process such as stroke or transient ischemic attack. Slurred speech can also be a sign of stroke or a drug reaction, including intoxication from drugs or alcohol.

What is the most common type of dysarthria?

A lesser variant of spastic dysarthria, called unilateral upper motor neuron dysarthria, is a similar speech pattern but usually less severe, associated with a unilateral upper motor neuron lesion such as in stroke. This may be the most common type of dysarthria encountered by neurologists.

How does hypokinetic dysarthria affect speech?

Hypokinetic dysarthria due to PD

This type of dysarthria is characterized by reduced vocal loudness, monotone, reduced fundamental frequency range, consonant and vowel imprecision, breathiness, short rushes of speech and irregular pauses.

What is the difference between dysarthria and apraxia?

People who live with apraxia have difficulty putting words together in the correct order or 'reaching' for the correct word while speaking. Dysarthria occurs when a patient's muscles do not coordinate together to produce speech.

How does dysphasia affect communication?

Dysphasia, also called aphasia, is a language disorder. It affects how you speak and understand language. People with dysphasia might have trouble putting the right words together in a sentence, understanding what others say, reading, and writing.

Can you be born with dysarthria?

Any area of motor skills may be affected by dysarthria. Either a child may be born with dysarthria or they may develop the condition prior to speech and language acquisition skills development, or following the development of early speech functions.

Can you have aphasia and dysarthria?

Dysarthria and aphasia have a lot in common. They are both communication impairments that can be the result of a stroke, and can even occur at the same time. Both conditions can make communication difficult.

What diseases cause speech problems?

Common conditions that can lead to speech disorders are:

• autism.
• attention deficit hyperactivity disorder (ADHD)
• strokes.
• oral cancer.
• laryngeal cancer.
• Huntington's disease.
• dementia.
• amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease.
