Memantine and Constraint-Induced Language Therapy in Chronic Poststroke Aphasia:A Randomized Controlled Trial
A Phase 4 study testing memantine and constraint-induced language therapy in people with Aphasia and Stroke, run by Gabinete Berthier y Martínez at 1 site in Spain.
Trial summary
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. Read more about this study

About this study
Official title: A 24-Week Pilot, Double-Blind, Randomized, Parallel, Placebo-Controlled Study of Memantine and Constraint-Induced Language Therapy in Chronic Poststroke Aphasia:Correlation With Cognitive Evoked Potentials During Recovery.
- 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).
Read the detailed description
- The efficacy of drugs that act on glutamate such as the N-methyl-D-aspartic acid (NMDA) receptor antagonist memantine requires to be explored in this population. The rationale for using memantine in post-stroke aphasia comes from recent studies on vascular dementia. Data extracted from a recent Cochrane review of randomized controlled trials of memantine in different types of dementia (vascular dementia, Alzheimer's disease, mixed dementia) reveal, after 6 weeks of treatment, beneficial effects on cognition (including language), activities of daily living, behavior and global scales as well as in the global impression of change.
- Recovery from aphasia is possible even in severe cases. While speech-language therapy remains as the mainstay treatment of aphasia, its effectiveness has not been conclusively proved. This has motivated the planning of more rational therapies (e.g., constraint-induced language therapy [Pulvermüller et al., 2001; 32: 1621-1626]).
- In addition, the neural correlates of improvement of language function can now be readily detectable with event-related potentials. This is a noninvasive technique that can detect in real time functional brain changes during recovery promoted by the combined action of memantine and constraint-induced language therapy.
- The aim of the present study is to assess the efficacy, safety profile, and functional correlates of memantine paired with massed language therapy in a sample of patients with chronic poststroke aphasia.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Marcelo L. Berthier, M.D., Ph.D. ((34) 952 22 45 90, mberthier@terra.es), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Language function (overall aphasia severity).. The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00196703, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Sep 2005.
