This article considers what communication is, its elements, what helps and what hinders it, and why it matters. It also considers managing people with communication differences and when communication is affected in special care dentistry (SCD). The article focuses on patients with hearing and visual impairments and considers how communication is affected and what techniques can be used to improve the situation. It offers recommendations for communicating with patients with neurological impairments typically seen after stroke, such as aphasia and dysarthria, with tips for the listener including the use of communication aids where appropriate. Finally it will consider communicating with patients who have autistic spectrum conditions and discuss how effective techniques and a tailored approach to their specific needs and anxieties can increase the likelihood of a successful dental visit.

Communication is the very essence of life for humans. This is made possible by the highly complex neurophysiological mechanisms governing humans. Any disturbance to this system can result in impairments of communication. HIV infection is one such disease. In India, the management of such individuals is usually restricted to life sustenance. Little importance is given to their communication problems, which play a vital role in day-to-day functioning. It is with this background that this study was conducted. Eight HIV-infected individuals participated in the study. They were subjected to assessment procedures that included the following tests: Western Aphasia Battery, Frenchay Dysarthria Assessment, Standard Articulation test, Fluency test, and subjective assessment of vocal parameters by a speech language pathologist. The results of the study reveal that individuals with HIV-1 infection show a varied picture of affected parameters of voice, swallowing, and oral motor functioning.

We have studied the configuration of the cortico-subcortical language networks within the right hemisphere (RH) in nine left-handers, being operated on while awake for a cerebral glioma. Intraoperatively, language was mapped using cortico-subcortical electrostimulation, to avoid permanent deficit. In frontal regions, cortical stimulation elicited articulatory disorders (ventral premotor cortex), anomia (dorsal premotor cortex), speech arrest (pars opercularis), and semantic paraphasia (dorsolateral prefrontal cortex). Insular stimulation generated dysarthria, parietal stimulation phonemic paraphasias, and temporal stimulation semantic paraphasias. Subcortically, the superior longitudinal fasciculus (inducing phonological disturbances when stimulated), inferior occipito-frontal fasciculus (eliciting semantic disturbances during stimulation), subcallosal fasciculus (generating control disturbances when stimulated), and common final pathway (inducing articulatory disorders during stimulation) were identified. These cortical and subcortical structures were preserved, avoiding permanent aphasia, despite a transient immediate postoperative language worsening. Both intraoperative results and postsurgical transitory dysphasia support the major role of the RH in language in left-handers, and provide new insights into the anatomo-functional cortico-subcortical organization of the language networks in the RH-suggesting a "mirror" configuration in comparison to the left hemisphere.

This paper uses the methodology of conversation analysis (CA) to examine the practice of co-constructed turn and utterance production in impaired communication. An investigation of the conversations between two family dyads, featuring one person with dysarthric speech and one with aphasic language, reveals one way in which single turns and utterances are produced through the collaborative activities of two people in interaction. Such a practice is shown to operate without problems for the participants or the need for explicit acceptance by the speakers. It is proposed that co-construction in disordered speech and language is one way in which communicative competence is accomplished. By drawing attention to similarities in the consequences of dysarthria and aphasia in everyday interaction, it is suggested that researchers and clinicians might profitably look across disorder-specific boundaries.

A 34-year-old woman with a previous history of severe headache ("thunderclap") was admitted with a diagnosis of aneurysmal subarachnoid hemorrhage (SAH). The patient developed symptomatic vasospasm on day 5 that resolved rapidly after having increased arterial blood pressure. She experienced also short-lasting excruciating headache. On day 12, while velocities had normalised, as revealed by transcranial Doppler (TCD), for more than 48 h, she developed aphasia and right hemiplegia associated with diffuse segmental vasospasm on the left middle cerebral artery. Intra-arterial infusion of vasodilatory agents was required. Recurrence of symptomatic vasospasm was noted on day 25, with a great number of territories involved as shown in the cerebral angiogram. A second intra-arterial treatment was needed. The patient complained of multiple episodes of extremely severe headache ("thunderclap"), with also transient dysarthria and hemiparesia on day 30. She was discharged on day 38 after full recovery. The clinical and TCD/radiological findings were consistent with a reversible cerebral vasoconstriction syndrome overlapping SAH related symptomatic vasospasm.

The clinical significance and characteristics of writing errors in bulbar-onset amyotrophic lateral sclerosis (ALS) are not clear. We retrospectively investigated writing samples in 19 patients with bulbar-onset ALS without preceding extra-motor symptoms. Co-development of dementia and/or aphasia was also explored and single photon emission computed tomography (SPECT) images of the brain were reviewed. As a result, a high prevalence of writing errors (15 of the 19 patients) was found. Of note were isolated writing errors with neither dementia nor aphasia verified in 2 patients whose dysarthria was mild enough to evaluate spoken language. The remaining 13 patients also showed agraphia, but either dysarthria was too severe to evaluate aphasia or frontotemporal dementia (FTD)-like features co-existed. Of these patients, one who initially lacked dementia subsequently developed FTD-like features. The frequent writing errors were omission or substitution of kana letters and syntactic errors. SPECT images showed bilateral or left-side dominant hypoperfusion in the frontotemporal lobes as a consistent feature. These results show that patients with bulbar-onset ALS frequently exhibit agraphic writing errors and that these are not merely consequences of dementia or aphasia. However, these writing errors may indicate the involvement of frontotemporal language-related areas beyond the primary motor cortex.

Up to 20% of patients with behavioural variants of frontotemporal dementia (FTD) also have motor neuron disease (MND); conversely, this comorbidity is rare in patients with language variants of FTD. A few patients have been reported with semantic dementia (SD) combined with MND. However, these patients demonstrated the clinical features of MND in the advanced stage. We report a patient with SD who also demonstrated MND symptoms in an earlier stage of the disease. A 61-year-old man visited our memory disorder clinic as a result of language disturbance and dysarthria of 8 months duration and facial recognition impairment of 3 months duration. Neuropsychological tests revealed anomic aphasia, prosopagnosia, and decreased semantic fluency. A brain MRI revealed significant atrophies localized in both anterior temporal lobes with a greater prominence on the right side. Clinical examination and electrophysiological studies confirmed a diagnosis of MND 17 months after the onset of the disease.

Progressive nonfluent aphasia (PNFA) is one of the 3 clinical presentations of frontotemporal lobar degeneration (FTLD), the other 2 being frontotemporal dementia and semantic dementia (SD). PNFA and SD, both representing relentlessly progressive language impairment in the realm of FTLD, may share a large part with primary progressive aphasia (PPA). A salient distinction between PPA and PNFA or SD is that PPA includes another clinical type, namely, logopenic/phonemic aphasia (LPA), which is not represented in FTLD. This is primarily because LPA is usually caused by Alzheimer's disease (AD) and the brunt of the lesion is localized at the left temporo-parietal region of the brain. Further, PNFA/SD should be limited to the clinical consequencies of FTLD while PPA is more generous with regard to its causal pathology. By definition, PNFA is an expressive language impairment which is characterized by effortful speech, phonemic errors, grammatical impairment, and word-finding difficulties. Reading and writing may be comparatively impaired. Comprehension of single word meaning is normal, while comprehension of sentencies may sometimes be impaired. PNFA should be differentiated from SD, LPA, and pure progressive apraxia of speech (AOS or alternatively referred to as aphemia or anarthria). SD may be distinguished from PNFA by virtue of its fluency, characteristic loss of word meaning and absence of agrammatism. LPA is similar to PNFA, yet differs in that there is preservation of grammatical skills and speech motor function that is devoid of AOS and/or dysarthria. AOS is an impairment at the level of speech motor programming without language impairment. Thus, there may be a double dissociation between AOS and PNFA i. e., PNFA may or may not accompany AOS and vice versa. PNFA is associated with a localized lesion in the left frontotemporal area of the brain. Immunohistochemical investigations have revealed that ubiquitin/TAR DNA binding protein-43 (TDA-43) positive and tau negative pathology, mostly FTLD with ubiquitin-positive inclusions (FTLD-U) type 3, accounts for 90% of PNFA cases, while the remaining 10% may be caused by tauopathy. Therapeutic attempts for PNFA are currently unsuccessful.

Dysarthria in Friedreich Ataxia (FA) is difficult to quantify. This study evaluated a series of performance measures for speech in 22 patients with genetically confirmed FA and 16 age-matched controls. Tests included the PATA examination, the PATAKA examination, the Oral Motor component of the Boston Aphasia examination, the Boston Cookie Theft description task, and the Assessment of Intelligibility of Dysarthric Speech. All measures, except the Cookie theft description task, demonstrated significantly lower scores for patients with FA when compared with controls and correlated with measures of disease progression. Thus, four of five measures capture speech dysfunction in FA and may provide feasible, inexpensive, quantitative testing for therapeutic monitoring in FA.

We reported the two cases with bulbar-onset ALS showing isolated agraphia without overt dementia and aphasia. Patient 1 was a 69-year-old man and patient 2 was an 81-year-old woman, and both were right-handed. Each patient developed dysarthria as an initial symptom followed by dysphagia, and neurological examinations showed atrophy and fasciculation of the tongue with upper and lower motor-neuron involvement of the extremities. These characteristic features with electromyographic evidence including widespread acute and chronic denervation led to a diagnosis of bulbar-onset ALS. Around 1 year after the onset of ALS, dysarthria was mild enough to allow oral communication enabling the determination that aphasia was absent with well preserved confrontation naming, repetition, reading and comprehension. The patients were polite without abnormal behavior or character change, and their general intelligence was also well preserved with excellent scores on the Mini Mental State Examination (30 and 27 points for patients 1 and 2, respectively) and Frontal Assessment Battery (16 points for each patient). However, spontaneous writing and dictation revealed abundant writing errors characterized by omission of kana letters and paragraphia of kana and kanji letters in both patients. Some syntactic errors were also observed in writing but in spoken language. A letter-number effect on writing errors was observed in patient 1. Copying of letters or words was intact and structure and orientation of written letters was well preserved, indicating the absence of constructional, apraxic or spatial feature of agraphia. Single photon emission computed tomography demonstrated reduced uptake in the bilateral frontotemporal lobes, predominantly in the left hemisphere, with less evident alternation in magnetic resonance imaging. Our results suggest that patients with bulbar-onset ALS may develop isolated agraphia as a single-domain cognitive impairment, preceding the clinical manifestation of aphasia or dementia. We speculate that the main responsible region might be the posterior part of the middle and inferior frontal gyri including Exner's writing center and Broca's area beyond the primary motor cortex.
