What neurological problems cause stuttering?
- Cerebrovascular accident (stroke), with or without aphasia.
- Head trauma.
- Ischemic attacks (temporary obstruction of blood flow in the Brain)
- Tumors, cysts, and other neoplasms.
- Degenerative diseases, such as Parkinson’s disease or multiple sclerosis.
What is a stutter stroke?
A stroke, traumatic brain injury, or other brain disorders can cause speech that is slow or has pauses or repeated sounds (neurogenic stuttering). Speech fluency can also be disrupted in the context of emotional distress.
What is laterality effect?
Laterality Effects: Humans. Certain regions of the human ventral visual pathway, which plays a crucial role in visual recognition, tend to respond vigorously to particular types of visually presented objects, such as buildings, words (in literates), and faces.
Is stuttering caused by brain damage?
Stutters often occur for a variety of reasons after a head injury. They are most frequently a result of damage to the language centers of the brain. However, sometimes there are no structural or neurological components that cause a stutter. Rather, they are a result of emotional trauma.
How does the brain repair stuttering?
The changes in the interactions of the cerebellum show that the brain compensates for stuttering”. Research also proves that differences in the structure and function of several regions of the brain contribute to stuttering and stuttering severity.
Can a brain tumor make you stutter?
Learning points. Acquired stuttering is rare neurological phenomenon that can occur as a result of acute neurological injury. Ischaemic stroke is a well-documented aetiology of acquired stuttering. This case report demonstrates the first description of acquired stuttering due to brain tumour recurrence.
Is stuttering a symptom of MS?
Speech problems, including slurring (dysarthria) and loss of volume (dysphonia) occur in approximately 25-40% of people with MS, particularly later in the disease course and during periods of extreme fatigue. Stuttering is occasionally reported as well.
What can cause stuttering all of sudden in adults?
A sudden stutter can be caused by a number of things: brain trauma, epilepsy, drug abuse (particularly heroin), chronic depression or even attempted suicide using barbiturates, according to the National Institutes of Health.
Does laterality mean left or right?
The term laterality refers to the preference most humans show for one side of their body over the other. Examples include left-handedness/right-handedness and left/right-footedness; it may also refer to the primary use of the left or right hemisphere in the brain.
What does laterality mean in medical terms?
laterality, in biological psychology, the development of specialized functioning in each hemisphere of the brain or in the side of the body which each controls.
Is there a link between stuttering and laterality?
Recent imaging studies of stutterers, however, have suggested that stuttering is tied to disturbed signal transmission between the hemispheres. Similar to the Iowa researchers of the 1930s, current investigators have found connections between stuttering and weak laterality.
How is stuttering behavior unique to the stuttering disorder?
The stuttering behavior was unique in that the patient was less fluent during propositional speech tasks.
Is stuttering an integral component of aphasia syndrome?
Indeed, stuttering or stuttering-like behaviors have often been described as an integral component of aphasia syndromes (Lebrun, Leleux, Rousseau, & Devreux, 1983).
What are some examples of extrapyramidal diseases associated with stuttering?
For example, apraxia of speech (“verbal apraxia”) is often associated with repetition of phonemes in a manner suggestive of neurogenic stuttering (e.g., Johns and Darley, 1970; Trost, 1971; Rosenbek, Messert, Collins, & Wertz, 1978). Koller (1983)reported six cases of stuttering associated with extrapyramidal diseases such as Parkinson’s disease.
