Dysarthria is a speech sound disorder resulting from neurological injury of the motor component of the motor–speech system [1] and is characterized by poor articulation of phonemes. [2] It is a condition in which problems effectively occur with the muscles that help produce speech, often making it very difficult to pronounce words.
Dysdiadochokinesia is also seen in Friedreich's ataxia and multiple sclerosis, as a cerebellar symptom (including ataxia, intention tremor and dysarthria). It is also a feature of ataxic dysarthria. Dysdiadochokinesia often presents in motor speech disorders , therefore testing for dysdiadochokinesia can be used for a differential diagnosis.
Dysarthria is the lack of motor skills required to produce understandable speech. Dysarthria is strictly a motor problem, and is not related to the patient's ability to comprehend speech. Strokes that cause dysarthria typically affect areas such as the anterior opercular, medial prefrontal and premotor, and anterior cingulate regions.
The tests are divided into categories evaluating posture and gait, kinetic functions, speech, and oculomotor functions. While these categories create useful categorization to assess which areas need to be focused on in therapies, this redundancy results in a longer test time, which can skew results of tests performed at the end of a session ...
Spinocerebellar ataxia type 6 (SCA6) is a rare, late-onset, autosomal dominant disorder, which, like other types of SCA, is characterized by dysarthria, oculomotor disorders, peripheral neuropathy, and ataxia of the gait, stance, and limbs due to cerebellar dysfunction. Unlike other types, SCA 6 is not fatal.

The Boston Diagnostic Aphasia Examination provides a comprehensive exploration of a range of communicative abilities. Its results are used to classify patient's language profiles into one of the localization based classifications of aphasia: Broca's, Wernicke's, anomic, conduction, transcortical, transcortical motor, transcortical sensory, and global aphasia syndromes, although the test does ...
Frontal lobe disorder, also frontal lobe syndrome, is an impairment of the frontal lobe of the brain due to disease or frontal lobe injury. [5] The frontal lobe plays a key role in executive functions such as motivation, planning, social behaviour, and speech production.
