Treatment for Word Retrieval Impairments in Aphasia
In this study the investigators are examining the effectiveness of two different speech therapy protocols for word retrieval impairments experienced by individuals with stroke-induced aphasia. One treatment involves errorless naming treatment and the other employs verbal plus gestural facilitation of word retrieval. Participants will receive one of the two treatments over several months. Before and after treatment the investigators will administer several tests and conversational samples to examine changes associated with the treatments. The investigators hypothesize that, whereas both treatments will lead to improvements in words rehearsed in therapy, communication outcomes in conversation will be broader for the verbal plus gestural protocol.

Medical and Biotech [MESH] Definitions
A type of fluent aphasia characterized by an impaired ability to repeat one and two word phrases, despite retained comprehension. This condition is associated with dominant hemisphere lesions involving the arcuate fasciculus (a white matter projection between Broca's and Wernicke's areas) and adjacent structures. Like patients with Wernicke aphasia (APHASIA, WERNICKE), patients with conduction aphasia are fluent but commit paraphasic errors during attempts at written and oral forms of communication. (From Adams et al., Principles of Neurology, 6th ed, p482; Brain & Bannister, Clinical Neurology, 7th ed, p142; Kandel et al., Principles of Neural Science, 3d ed, p848)
Involuntary ("parrot-like"), meaningless repetition of a recently heard word, phrase, or song. This condition may be associated with transcortical APHASIA; SCHIZOPHRENIA; or other disorders. (From Adams et al., Principles of Neurology, 6th ed, p485)
Primary Progressive Nonfluent Aphasia
A form of frontotemporal lobar degeneration and a progressive form of dementia characterized by motor speech impairment and AGRAMMATISM, with relative sparing of single word comprehension and semantic memory.
Treatments which are undergoing clinical trials or for which there is insufficient evidence to determine their effects on health outcomes; coverage for such treatments is often denied by health insurers.
Learning in which the subject must respond with one word or syllable when presented with another word or syllable.
This is a behavioral speech therapy trial for individuals who have suffered a stroke on the left side of the brain and have difficulty speaking. The name of this disorder is called 'aphas...
The purpose of this investigation is to further develop and test a treatment for word-finding problems in aphasia. The treatment is designed to strengthen meaning associations within categ...
The purpose of this study is to determine if an "intentional act" improves treatment response for patients with nonfluent aphasia. The treatment involves naming pictures and saying member...
The study investigates the possibility that levetiracetam may improve the symptoms of chronic post-stroke aphasia.
The purpose of this research is to utilize functional magnetic resonance imaging (fMRI) to investigate brain reorganization for language behavior in stroke patients with aphasia. A primary...
We compared the effects of two treatments for aphasic word retrieval impairments, errorless naming treatment (ENT) and gestural facilitation of naming (GES), within the same individuals, anticipating...
PURPOSE: The current study attempts to develop valid indicators of stress in individuals with aphasia by examining the relationship between certain language variables (error frequency and word product...
BACKGROUND: . Current knowledge regarding the time course of aphasia recovery is based on observations limited to the first years after stroke. OBJECTIVE: . The authors studied long-term outcome (25 y...
Therapy for naming impairments post-stroke typically involves semantic and/or phonologically-based tasks. However, the relationship between individuals' locus of breakdown in word retrieval and their...
Implicit learning is a process of acquiring knowledge that occurs without conscious awareness of learning, whereas explicit learning involves the use of overt strategies. To date, research related to...
