Predicting recovery from aphasia with connectionist networks: preliminary comparisons with multiple regression.

We trained a series of simulated neural networks with the raw scores on the Western Aphasia Battery from 91 aphasic patients. Patients were tested at 3 and at 12 months post onset. The most successful network we trained is able to predict AQ for an individual in 12 months from the raw scores at 3 months post-onset to a tolerance of + or -4.5. We then compared the relative success of a small range of trained networks to predict recovery with linear multiple regression. With the small groups of subjects involved in this preliminary study, the networks appeared to be more successful at predicting recovery.

Language in dementia of recent referral.

Twenty-four recently referred patients with dementia were assessed on a range of language tests and a mental status test. The tasks which appeared to present the most difficulties for the patients were written spelling, pragmatic processing tasks like sentence disambiguation and proverb interpretation. 'Straight' linguistic processing tasks sensitive to aphasia, like oral reading, serial identification of objects, naming and correction of semantically incorrect sentences, appeared to present fewer problems. It is concluded that certain language tasks may be useful and sensitive detectors of developing dementia, and that in early dementia those aspects of language which depend on straight linguistic processing can be relatively preserved.

Neurolinguistic analysis of recurrent utterance in aphasia.

A linguistic analysis of 97 recurrent utterances (RUs) is reported which delineates 2 separate types of RU - Real Word Recurrent Utterances (RWRUs) and Non-Meaningful Recurrent Utterances (NMRUs). The range, frequency and distribution of phonemes occurring in RUs is similar to normal English in RWRUs, but not in NMRUs. NMRUs do not break the phonotactic constraints of the language and RWRUs rarely break the syntactic rules. It appears to be possible to classify RWRUs into certain groups among which a Pronoun + Verb and an Expletive group are the most interesting. Expletive RUs were all produced by male subjects and Pronoun + Verb RUs deserve further investigation. Implications for rehabilitation are discussed.

On the origins of recurrent utterances in aphasia.

The origin of the two linguistically distinct recurrent utterance types--real word recurrent utterances (RWRUs) and non-meaningful recurrent utterances (NMRUs) - is discussed. It is argued that the origins of RWRUs may have more to do with post-onset factors than with activities being pursued at the time of onset, and the origins of NMRUs are probably best explained in phonetic terms. It may be the case that the right hemisphere is involved to different degrees in the production of the two linguistically distinct classes of recurrent utterances.

A multinational comparison of aphasia management practices.

The effect of restructuring of healthcare on the quality, quantity, and nature of aphasia management is largely unknown. The current study is the first to examine access, diagnostic, treatment, and discharge patterns of patients with aphasia in Australia, Canada, the UK, the US private sector (US-Private), and the US Veterans Health Administration in the Department of Veterans Affairs (US-VA). The authors developed a 37-item survey to be completed by clinicians working with aphasic patients. The survey focused on eight areas: access to care, evaluation procedures, group treatment, number and duration of treatment sessions, limitations of the number of sessions, termination of treatment, follow-up practices, and resumption of treatment. 394 surveys were distributed and 175 were returned completed (44% return rate). Respondents represented a range of ages, work experiences, and work settings. There was considerable consistency among respondents from our five healthcare systems. Results suggest that patients may be routinely denied treatment in direct contradiction to the research literature. Just as we carefully monitor the progress of patients receiving our treatment, we are obliged to monitor the effects of managed care on our patients, fellow clinicians, and our profession.

Perceptions of psychosocial adjustment to acquired communication disorders: applications of the Code-Müller Protocols.

The 'Code-Müller protocols' (CMP) were introduced in 1983 and originally aimed to compare perceptions of psychosocial adjustment to aphasia and related disorders from the separate perspectives of patients, relatives and speech and language therapists as a basis for counselling. In later studies the items of the CMP were also used to examine perceptions of their importance as possible therapy targets in the rehabilitation of people with communication disorders. This paper describes the development of the CMP and presents an overview of their application in aphasia, laryngectomy and acquired deafness and discusses some clinical implications. Studies published in the past 15 years show that aphasic people and their relatives or significant others are significantly more optimistic concerning psychosocial adjustment than their therapists. Furthermore, optimism changes during the course of illness. The relative weightings given for therapy or rehabilitation targets significantly differ between different professional groups concerned with aphasia rehabilitation (speech and language therapists/pathologists, physiotherapists, occupational therapists, psychologists and physicians) and are influenced by clinical experience.
