A study of 21 patients with Alzheimer's Disease and 25 with vascular dementia, the two most common forms of dementia, investigated language impairments in the dementia syndrome to see if analysis of language disturbances is helpful in differential diagnosis. Diagnostic assessment included a neurological examination, detailed medical history,…

Discusses the difficulties in diagnosing phonetic and phonemic disorders in aphasics. (AM)

This investigation examines in aphasics the loss of the ability to relate words to their grammatical categories. It finds that recognition of grammatical categories is lost in all forms of aphasia studied, but that the loss is manifested differently for different types of aphasia quantitatively and qualitatively. (SCC)

A survey of the historical developments of linguistic theories relating to aphasia. Some topics covered are: the breakdown of language as opposed to acquisition of language; functional structuralism basic to neurolinguistics; analysis of language disorders; neurolinguistics--models and typology; aphasia and agraphia. (Text is in French.) (AMH)

Attempts to answer several questions posed by researchers in agraphia. The questions concern analysis of errors in sensory aphasia; a typology of sensory agraphia; a possible relationship between sensory agraphia and sensory aphasia; and questions of a neurolinguistic order and those of a purely linguistic order. (Text is in French.) (AMH)

Patients with cortical lesions, both with or without aphasia, were asked to reconstruct sentences. It was found that syntactic comprehension deficits exist only in aphasics. Two groups are distinguishable, those with deficits due to problems of repetition and those with deficits due to problems of object recognition. (Text is in French.) (TL)

Agrammatism, the disruption of the grammatical structure of speech, is studied in its accompaniment to aphasia. Since it occurs with all studied forms of aphasia, it is considered here a symptom typical to aphasia. It is also examined in relation to different kinds of aphasics. (SCC)

The relation between reading and writing is important because tacit and possibly unwarranted assumptions underlie the theories and pedagogies which govern these processes. These assumptions are challenged by the claims that: (1) reading and writing are related in neurolinguistically specifiable ways; (2) they do not seem to be simple inverses of…

Changes in frequency of occurrence of the following linguistic variables in recovery from aphasia due to left temporal lobe lesions are analyzed in text and graphs: (1) quantity of verbalization, (2) syntactic structure: subject-verb-object vs. topic-comment, (3) syntactic complexity, (4) nouns and verbs, (5) morphology, (6) anaphora, and (7)…

A report on a study of a large number of subjects afflicted with sensory aphasia. Topics covered are: the distributional pattern of grammatical categories; paraphasia; a statistical analysis of associated syndromes; possible relationship to the location of the lesion. Some examples of spontaneous language are included. (Text is in French.) (AMH)

Describes the various anomalies which occur in people's writing when there is right brain damage; compares writing impairments to the reading and drawing impairments that these patients also show. Analyzes the phenomenom of unilateral visual neglect and suggests hypotheses as to the nature of this disorder. (SED)

Results of a verbal sound and meaning discrimination test to check the hypothesis of Alajouanine et al.--that two types of paraphasics can be distinguished, phonemic and semantic--are discussed. The former are impaired in tests of auditory language discrimination, the latter show regression of the semantic values apparent in their linguistic…
