BACKGROUND/AIMS This study examined the spectral characteristics of American English vowels in dysarthria associated with cerebral palsy (CP), and investigated the relationship between a speaker's overall speech intelligibility and vowel contrast. METHODS The data were collected from 12 American English native speakers (9 speakers with a diagnosis of CP and 3 controls). Primary measures were ...

The aims of this study were to: (1) evaluate the perceptual speech dimensions, speech intelligibility and dys arthria severity of a group of individuals diagnosed with Friedreich’s ataxia (FRDA); (2) determine the presence of subgroups within FRDA dysarthria; (3) investigate the relationship between the speech outcome and the clinical factors of disease progression. The study included 38 indivi...

Electromyograms were recorded with hooked-wire electrodes from sixteen lip, tongue and jaw muscles in six normal and seven cerebral palsied adult subjects during a variety of speech and non-speech tasks. The recorded patterns of muscle activity fail to support a number of theories concerning the pathophysiology of dysarthria in cerebral palsy. There was no indication of weakness in individual a...

Posterior reversible encephalopathy syndrome (PRES) is a rare neurologic disorder that presents with variable symptoms and symmetrical abnormal white matter signaling most commonly of the occipital parietal lobes on magnetic resonance imaging (MRI). PRES, also known as posterior leukoencephalopathy (RPLS) associated hypertension. Hypomagnesemia’s association PRES has been rarely reported. Here,...

Background: Neuronal Ceroid Lipofuscinoses (NCL) is a neurodegenerative condition of lysosomal metabolism due to accumulation lipofuscin in neurons. The predominant symptoms are motor and cognitive regression, seizures, ataxia retinopathy. Speech-language disorders such as dysarthria, aphasia dysphagia have been reported.
