Effects of Antimuscarinics on Cognition in Spinal Cord Injury

November 16, 2015 updated by: Swiss Paraplegic Centre Nottwil

Effects of Antimuscarinic Drugs on the Cognition of Patients With Acute Spinal Cord Injury

Prospective evaluation of the cognitive function of in-house patients suffering from an acute traumatic spinal cord injury before and three months after the initiation of antimuscarinic treatment.

The following hypothesis will be tested: Antimuscarinic treatment results in significantly worse cognitive test results three months after traumatic spinal cord injury compared to the pre-treatment results and the results of the control group.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

There will be two groups: 1) patients receiving antimuscarinic treatment 2) patients without antimuscarinic treatment (control).

The control group will be investigated in order to determine the effects of traumatic spinal cord injury on cognition and the natural history of potential cognitive impairment within the first three months after spinal cord injury.

Six to eight weeks after traumatic spinal cord injury, patients are examined in order to determine the type of neurogenic bladder dysfunction they are suffering from. Patients suffering from an overactive bladder will receive antimuscarinic treatment in order to prevent high urine storage and voiding pressures, that put the kidneys at risk.

Prior to the urologic examination, patients fulfilling inclusion criteria will be contacted. If informed consent is given, cognitive function will be evaluated in both patient groups using different standard neuropsychologic tests. The same neuropsychologic tests will be repeated three months later. Evaluation will take place under standardized conditions (e.g. time of day).

Furthermore,different factors influencing cognition, e.g. depression, pain, medication, will be assessed at the beginning and end of the study.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
