TL;DR: A brief review of terminology associated with AOS, its clinical hallmarks and neuroanatomical correlates, current models of motor programming will also be addressed as they relate to AOS and typical treatment strategies used in rehabilitating the articulation and prosody deficits associatedwith AOS will be summarized.
Abstract: Apraxia of speech (AOS) is a motor speech disorder that can occur in the absence of aphasia or dysarthria. AOS has been the subject of some controversy since the disorder was first named and described by Darley and his Mayo Clinic colleagues in the 1960s. A recent revival of interest in AOS is due in part to the fact that it is often the first symptom of neurodegenerative diseases, such as primary progressive aphasia and corticobasal degeneration. This article will provide a brief review of terminology associated with AOS, its clinical hallmarks and neuroanatomical correlates. Current models of motor programming will also be addressed as they relate to AOS and finally, typical treatment strategies used in rehabilitating the articulation and prosody deficits associated with AOS will be summarized.

TL;DR: The results show that this speaker was significantly less intelligible when speaking spontaneously than in the other tasks, which indicates that speech production task may be an important variable to consider during the evaluation of dysarthria.

TL;DR: Clinical and anatomic data is gathered on four patients with this dysarthria without aphasia, caused by small lesions of the motor system for articulation: pars opercularis, inferior prerolandic gyrus, or white matter deep to those regions.
Abstract: • A syndrome of dysarthria following the appearance of small left frontal-lobe lesions has been recognized for many years but identified by numerous labels Varied terminology has led to confusion in the literature and inadequate recognition of this syndrome as a distinctive clinical entity We gathered clinical and anatomic (computed tomographic) data on four patients with this dysarthric syndrome and reviewed cases from the literature that contained sufficient clinical and anatomic data for comparison These patients had a distinctive syndrome of dysarthria without aphasia, caused by small lesions of the motor system for articulation: pars opercularis, inferior prerolandic gyrus, or white matter deep to those regions This syndrome should be distinguished from Broca's aphasia, Broca's area aphasia, transcortical aphasia, and subcortical aphasia Aphemia is not mild Broca's aphasia; it is severe dysarthria, at times in the setting of transient Broca's aphasia

TL;DR: This study shows that speech manifestations are common in complex partial seizures of temporal lobe origin and can provide an excellent clinical tool for lateralization of seizure onset.
Abstract: To evaluate the role of speech manifestations in lateralization of temporal lobe seizures, we reviewed videotapes of 100 complex partial seizures in 35 patients who underwent temporal lobectomy for intractable epilepsy. All patients had prolonged electroencephalographic video monitoring with scalp and subdural electrodes, and their speech dominance was determined with an intracarotid amobarbital test. Speech manifestations were observed in 79 seizures and were classified as vocalization, normal speech, or abnormal speech. Vocalization of sounds without speech quality occurred ictally in 48.5% of patients. Normal speech (identifiable speech) occurred ictally in 34.2% of patients. Abnormal speech (speech arrest, dysphasia, dysarthria, and nonidentifiable speech) occurred in 51.4% of patients, either ictally or postictally. Of all the above speech manifestations, only postictal dysphasia and ictal identifiable speech had significant lateralizing value: 92% of patients with postictal dysphasia had their seizures originating from the dominant temporal lobe (p < 0.001), and 83% of those with ictal identifiable speech had their seizures from the nondominant side (p = 0.013). This study shows that speech manifestations are common in complex partial seizures of temporal lobe origin and can provide an excellent clinical tool for lateralization of seizure onset.

TL;DR: The speech of five individuals with cerebellar disease and ataxic dysarthria was studied with acoustic analyses of CVC words, words of varying syllabic structure, simple sentences, the Rainbow Passage, and conversation, where the most consistent and marked abnormalities observed in spectrograms were alterations of the normal timing pattern.
