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

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

55 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

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.
Outcome Measure
Measure Description
Time Frame
Event-related Potential (ERP) P300 Latency at Baseline
Time Frame: At Baseline (Day 1)
ERP P300 was a method of recording brain activity elicited by external stimuli, for example (e.g.), an oddball auditory stimulus, particularly of working memory access. The participant had to perform a task related to auditory stimuli in order to assess the P300 component (latency). The stimulus consisted of an oddball paradigm with 2 sound stimuli. Stimuli were presented through headphones and auditory stimulation for P300 was assessed in a recording lasting up to 10 minutes. It was calculated as the average across the pre-dose values at Baseline visit. Baseline was defined as Day 1.
At Baseline (Day 1)

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.
Outcome Measure
Measure Description
Time Frame
Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog11) at Baseline
Time Frame: At Baseline (Day 1)
The ADAS-Cog11 was designed to measure cognitive symptom change in participants with Alzheimer's Disease (AD) and consisted of 11 tasks. It was performed to evaluate the correlation of ERP P300 latency and cognition. The standard 11 items (and corresponding score range) were: word recall (0-10), commands (0-5), constructional praxis (0-5), naming objects and fingers (0-5), ideational praxis (0-5), orientation (0-8), word recognition (0-12), spoken language ability (0-5), comprehension of spoken language (0-5), word-finding difficulty (0-5), and remembering test instructions (0-5). The test included 7 performance items and 4 clinician-rated items. The ADAS-Cog11 total score was the sum of all 11 individual items, with a total score ranging from 0 (no impairment) to 70 (severe impairment). Higher scores indicated more severe cognitive impairment. Baseline was defined as Day 1.
