Filter by:Adults who sustain brain damage due to stroke, traumatic injury or surgery may develop difficulty finding words. This study compares the effectiveness of two behavior-based programs to improve picture naming ability in these individuals.
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 focus of the study is on recovery of nonfluent propositional speech and naming in chronic aphasia patients. The fMRI technique is used to examine activation in the left hemisphere (LH) and right hemisphere (RH), during recovery of specific language behaviors in chronic nonfluent aphasia patients.
The study investigates the possibility that levetiracetam may improve the symptoms of chronic post-stroke aphasia.
The purpose of this study is to investigate the effects of intensive, constraint induced language therapy (CILT) for individuals with chronic aphasia compared with traditional aphasia therapy. The specific objectives of the proposed research are to determine the effects of therapy type (CILT vs. traditional) and dose density (intensive or distributed) on speech therapy outcome. In addition, we will investigate the functional and qualitative impact of these interventions on functional communication.
- Aphasia, the loss or impairment of language caused by brain damage, is one of the most devastating cognitive impairments of stroke. Aphasia can be treated with combination of speech-language therapy and drugs. Conventional speech-language therapy in chronic aphasic subjects is of little help and several drugs have been studied with limited success. Therefore other therapeutic strategies are warranted. - Recent data suggest that drugs (memantine) acting on the brain chemical glutamate may help the recovery of cognitive deficits, included language, in subjects with vascular dementia. The present study examines the safety profile and efficacy of memantine paired with intensive language therapy in subjects with stroke-related chronic aphasia (more than 1 yr. of evolution).
- Aphasia (impairment of language function due to brain damage)may be treated with speech-language therapy and drugs. Several drugs have been studied but with limited success. - Recent data suggest that the neurotransmitter acetylcholine may be reduced in brain damaged subjects and that drugs that stimulates acetylcholine activity may help recovery of aphasic deficits particularly when paired with speech-language therapy. - Recent evidence indicates that medicaments acting on the neurotransmitter acetylcholine may promote improvement of aphasic deficits and our previous open-label study of donepezil in post-stroke aphasia showed benefits in all patients and observed benefit were long-lasting (6 months).This study will test the safety and efficacy of donepezil (an agent acting on acetylcholine)in subjects with stroke-related chronic aphasia (more than 1 yr of evolution).
The primary objective of this feasibility study is to evaluate the safety and effectiveness of targeted sub-threshold epidural cortical stimulation delivered concurrent with speech-language rehabilitation activities to enhance recovery in study subjects suffering from Broca's aphasia (the inability to speak or to organize the muscular movements for speech), following a stroke.
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 categories of words (e.g., animals, tools, fruits). The treatment is also designed to be used as a search strategy in instances of word-finding difficulty. The study was devised to evaluate the extent to which treatment increases the ability to recall trained, as well as untrained, words.
The purpose of this study is to evaluate the effects of Response Elaboration Training (RET), which is a speech/language therapy for aphasia. The study is designed to determine whether verbal language production improves in terms of content and length of utterances as a result of treatment.
The purpose of this study is to determine whether levodopa, in combination with a high frequency language training, is effective in boosting naming performance in patients with aphasia.
