Amantadine and Functional Improvement Following ABI Measured by MRI Tractography; A Pilot Study
Mechanism of Amantadine and Functional Improvement Following Acquired Brain Injury as Measured by MRI Tractography; A Pilot Study

Descrizione dettagliata
Primary Aim:
To determine the size of the RAS tracts as measured by MRI tractography. Specifically, the investigators will be measuring the fiber tracts that project through the posterior thalamus. The RAS is involved in mediating arousal and consciousness. The size of fiber tracts will be measured prior to initiating treatment and near the time of discharge from the rehabilitation hospital or at approximately ninety-days. It is hypothesized that treatment will result in an increase in the size of these fiber tracts.
As a pilot study, the investigators will be determining the feasibility of recruiting and retaining patients in this type of study. This will allow the clarification and understanding of the technical standards for MRI tractography related to the assessment of the reticular activating system.
Secondary Aim:
To determine and monitor changes in function following acquired brain injury as measured by the Disability Rating Scale (DRS) score. The DRS score will be obtained prior to initiating treatment and at termination of the study. It is hypothesized that treatment with amantadine in addition to standard medical treatment, will be associated with an improvement in function.

Altro: Treatment and MRI scanning
After informed consent has been obtained, the subjects will be examined by a physician and assigned a Disability Ratings Scale (DRS) score.
Subjects will undergo MRI tractography study, which does not require the administration of contrast.
All participants will receive oral amantadine at escalating doses to ensure tolerance (50mg twice daily for 7 days, then 100mg twice daily for 1 week, then 150mg twice daily, then 200mg twice daily).
The usual length of stay on the inpatient brain injury program is ninety days.
The MRI tractography study and DRS score will be repeated near the time of discharge or ninety days from enrollment.
|
Participants will initially receive amantadine at the starting dose of 50mg twice daily either by mouth or feeding tube.
The dosage will increase every week by 50mg twice daily (100mg total dose increase) up to the target dose of 200mg twice daily.
These are the usual doses and rate of increase that are offered to patients with brain injury.
Altri nomi:
Participants will initially receive a baseline MRI Tractography scan.
The size of RAS fiber tracts will be measured prior to initiating treatment and near the time of discharge from the rehabilitation hospital or at approximately ninety-days.
