Growing evidence supports the likelihood of cerebellar involvement specifically affecting speech motor programming and execution pathways, producing the characteristic features associated with ataxic dysarthria. This link to speech motor control can explain the abnormalities in articulation and prosody, which are hallmarks of this disorder. [11]
Cerebellar cognitive affective syndrome (CCAS), also called Schmahmann's syndrome [1] is a condition that follows from lesions (damage) to the cerebellum of the brain. It refers to a constellation of deficits in the cognitive domains of executive function, spatial cognition, language, and affect resulting from damage to the cerebellum.
The cerebellar theory of dyslexia asserts that the cause of dyslexia is an abnormality in the cerebellum (a region in the back of the brain), which in turn cause disruption in normal development, which causes issues with motor control, balance, working memory, attention, automatization, and ultimately, reading.
Scanning speech is a type of ataxic dysarthria in which spoken words are broken up into separate syllables, often separated by a noticeable pause, and spoken with varying force. [1] The sentence "Walking is good exercise", for example, might be pronounced as "Walk (pause) ing is good ex (pause) er (pause) cise".
They develop in the cerebellar primordium that covers the fourth ventricle and below a fissure-like region called the isthmus of the developing brain. Purkinje cells migrate toward the outer surface of the cerebellar cortex and form the Purkinje cell layer. Purkinje cells are born during the earliest stages of cerebellar neurogenesis.
The template provides a link to a key so that readers may easily discover how to pronounce an easily mispronounced or difficult-to-pronounce word. For example: Worcestershire (/ ˈ w ʊ s t ər ʃ ər / WUUS-tər-shər) is a county located in central England.
Subvocalization, or silent speech, is the internal speech typically made when reading; it provides the sound of the word as it is read. [1] [2] This is a natural process when reading, and it helps the mind to access meanings to comprehend and remember what is read, potentially reducing cognitive load.
The following are the non-pulmonic consonants.They are sounds whose airflow is not dependent on the lungs. These include clicks (found in the Khoisan languages and some neighboring Bantu languages of Africa), implosives (found in languages such as Sindhi, Hausa, Swahili and Vietnamese), and ejectives (found in many Amerindian and Caucasian languages).
