Does myoclonus affect speech?
Discussion: In MDS, myoclonus has only infrequently been reported to affect speech. This case further expands the spectrum of conditions causing the rare clinical phenomenon of speech-activated myoclonus.
Is myoclonus a neurological disorder?
These forms of myoclonus occur in healthy people and rarely present a problem. Other forms of myoclonus may occur because of a nervous system (neurological) disorder, such as epilepsy, a metabolic condition, or a reaction to a medication.
How do you examine myoclonus?
Magnetic resonance imaging (MRI) An MRI scan may be used to check for structural problems or tumors inside your brain or spinal cord, which may cause your myoclonus symptoms. An MRI scan uses a magnetic field and radio waves to produce detailed images of your brain, spinal cord and other areas of your body.
What is stimulus sensitive myoclonus?
Stimulus sensitive myoclonus is a type of myoclonus triggered by outside stimuli such as lights, noise or movement. It can be brought on by surprise as well.
Can myoclonic seizures be vocal?
The disease is characterized by involuntary, abrupt, muscular movements called ” tics”, and uncontrollable vocal sounds. Sometimes inappropriate words may occur. Tourette Syndrome is not a degenerative disorder and those affected can expect to live a normal life span.
Will myoclonic jerks go away?
Myoclonus refers to sudden, brief involuntary twitching or jerking of a muscle or group of muscles. It describes a clinical sign and is not itself a disease. The twitching cannot be stopped or controlled by the person experiencing it.
Are myoclonic jerks harmful?
These types of myoclonus are rarely harmful. However, some forms of myoclonus can cause recurring, shock-like spasms that can interfere with a person’s ability to eat, talk, and walk.
How would you describe myoclonus?
Myoclonus is a clinical sign that is characterized by brief, shock-like, involuntary movements caused by muscular contractions or inhibitions [1]. Muscular contractions produce positive myoclonus, whereas muscular inhibitions produce negative myoclonus (ie, asterixis).
What is Lance Adam syndrome?
Abstract. Lance-Adams syndrome (LAS) is a rare complication of successful cardiopulmonary resuscitation and is often accompanied by action myoclonus. LAS is seen in patients who have undergone a cardiorespiratory arrest, later regained consciousness, and then developed myoclonus days or weeks after the event.
What triggers myoclonus?
Stimulus-sensitive myoclonus is triggered by various external events, including noise, movement, and light. Being surprised may increase the sensitivity of the individual. Sleep myoclonus (or hypnic myoclonus) occurs during sleep and sleep transitions, often as one is dropping off to sleep.
Is myoclonus a seizure?
A myoclonic seizure is a type of generalized seizure, meaning it occurs on both sides of the brain. It causes muscle jerking that often lasts for 1 or 2 seconds. To learn more about myoclonic seizures, read on. We’ll cover the symptoms, causes, and treatment, along with the different types of myoclonic epilepsies.
What is speech-activated myoclonus?
Speech-activated myoclonus is typically a function of the type of speech: spontaneous or rote. In their case series, Slee et al. demonstrated that oropharyngeal movements not involving the vocal cords (e.g. whistling, chewing, swallowing) failed to trigger myoclonus.
Can myoclonus cause stuttering while reading?
The patient continued to exhibit stuttering-like speech while reading even when no visible myoclonus was evident, presumably as a result of myoclonus in his vocal musculature. His speech was most affected while reading aloud, with much less prominent speech disruption during spontaneous vocalization.
What is a speech pathologist SLP?
Speech-Language Pathology Evaluation and Management of Hyperkinetic Disorders Affecting Speech and Swallowing Function SLPs play an important role in contributing to the differential diagnosis and management of impaired speech and deglutition associated with hyperkinetic disorders.
