piracetam and Amnesia

piracetam has been researched along with Amnesia in 47 studies

Piracetam: A compound suggested to be both a nootropic and a neuroprotective agent.

Amnesia: Pathologic partial or complete loss of the ability to recall past experiences (AMNESIA, RETROGRADE) or to form new memories (AMNESIA, ANTEROGRADE). This condition may be of organic or psychologic origin. Organic forms of amnesia are usually associated with dysfunction of the DIENCEPHALON or HIPPOCAMPUS. (From Adams et al., Principles of Neurology, 6th ed, pp426-7)

Trial Outcomes

Functional Connectivity Strengths of Neural Networks

The seed-based functional connectivity strengths of the hippocampus network and the default mode network will be employed to measure the changes between AGB101 and Placebo perturbation. The functional connectivity strengths will be measured with the median of the Pearson cross-correlation coefficients over entire brain regions. (NCT03461861)

Rey Auditory Verbal Learning Test (AVLT), Delayed Recall Scaled Integer. The Higher is the Better

Rey Auditory Verbal Learning Test (AVLT), delayed recall Scaled integer will be employed to measure the episodic memory changes before and after AGB101 treatment. The AVLT score will be recorded as a standard score. The theoretical range: min 50, max 155, the higher the better. The higher the number is, the better the memory. It is an integer number.

ADAS-cog in AD With Epileptiform Activity

Alzheimer's Disease Assessment Scale - Cognitive Subscale (ADAS-cog) - The ADAS-cog rating instrument (Rosen et al. 1984) will be used to evaluate the global cognitive functioning. The ADAS-cog is a 70-point scale that includes an assessment of verbal memory, language, orientation, reasoning, and praxis.The score is derived from adding point values from each of its subsections. The higher your score on the ADAS-cog, the better you do. (NCT02002819)

Blood Serum Prolactin Level

Blood samples intended for Quest Diagnostics LEV and prolactin serum levels (one 6 mL tube) will be processed in the following manner, as outlined in the Quest Diagnostics lab manual. The whole blood will be allowed to clot for 60 minutes and centrifuged at 2200 - 2500 revolutions per minute (RPM) for at least 15 minutes. The resulting serum will be split into 2 cryovials which will be stored at -20°C and immediately shipped for external assessment of LEV and prolactin levels. Prolactin will be assessed via immunoassay. The concentration of LEV in serum will be measured using validated liquid chromatography/tandem mass spectrometry (LC/MS-MS) methods. (NCT02002819)

Changes in Behavior and Level of Disability - ADCS-ADL

Alzheimer's Disease Cooperative Study Activities of Daily Living Scale (ADCS-ADL) - The ADCS-ADL rating instrument (Galasko et al. 1997) will be used to evaluate functional capacity. The ADCS-ADL is a caregiver rated questionnaire. Scores on the 24-item ADCS-ADL range from 0 to 78. A higher score indicates less severity while a lower score indicates greater severity.

Changes in Behavior and Level of Disability - ADCS-CGIC

ADCS-Clinical Global Impression of Change (ADCS-CGIC) - The ADCS-CGIC is a seven-point scale that gives a global rating of change from baseline (Schneider et al. 1997). The baseline and follow up assessments are based on interviews with the subject and the informant. The ADCS-CGIC is a clinician-rated measure of: global severity at baseline scored from 1 (normal, not at all ill) to 7 (among the most extremely ill patients); and global change at follow-up scored from 1 (marked improvement) to 7 (marked worsening), where 4 indicates no change.

Changes in Behavior and Level of Disability - Neuropsychiatric Inventory (NPI)

Neuropsychiatric Inventory (NPI) - The NPI (Cummings et al. 1994) will be used to evaluate the severity of behavioral symptoms. The severity scale has scores ranging from 1 to 3 points (1=mild; 2=moderate; and 3=severe) and the scale for assessing caregiver distress has scores ranging from 0 to 5 points (0=no distress; 1=minimal distress; 2=mild distress; 3=moderate distress; 4=severe distress; and 5=extreme distress).

Changes in Cognitive Function as Measured by a Virtual Route Learning Test

A 20-minute computer-based virtual navigation test will be used to assess how well a subject can navigate a virtual community to reach a goal destination. The subjects will then be measured on their ability to accurately navigate the virtual community after a period of a few hours. The subject's performance after the study treatment will be compared with results from a baseline assessment done before the study treatment, using statistical tests to assess whether there was any significant change.

Changes in Epileptiform Events

"Epileptiform activity will be measured using a 1-hr resting magnetoencephalogram/electroencephalogram (M/EEG). M/EEG can detect abnormal epileptiform findings called spikes. The M/EEG will be read by an epileptologist with specialized training to assess whether there are any spikes. If spikes are observed during the M/EEG they will be counted to determine their frequency (e.g., 5 spikes per 1 hour recording). The frequency of spikes will then be compared to baseline values from before beginning the study treatment, using statistical tests to determine if the frequency changed with treatment."

Changes in Executive Function as Measured by the NIH EXAMINER Computer Battery

Changes in executive function were measured using the NIH EXAMINER, a 1-hour computer-based battery of various executive function tasks. The subject's performance after the study treatment will be compared with results from a baseline assessment done before the study treatment, using statistical tests to assess whether there was any significant change. The Examiner assessment consists of the following scales: antisaccade , set shifting , flanker task, dot counting, spatial 1-back, category fluency, and letter fluency. Scores for this task have an indefinite range. Higher scores however do indicate better performance. Scores for this scale were generated using item response theory. For this study, scores with SEs greater than 0.55 were classified as unreliable and excluded from analysis. Composite scores from 2 participants were excluded on this basis.The EXAMINER ranges for the participants in the study were -2.59 to 1.33. (NCT02002819)

Changes in Stroop Interference Naming

Stroop Test - The Stroop Test (Stroop 1935) will be used to assess executive functions including selective attention, cognitive flexibility and processing speed. Subtasks include Stroop color naming and Stroop interference naming, and each subtask is restricted to 1 minute. The minimum score is 0 and the maximum score is 126. The higher the score the better a participant does. (NCT02002819)

Clinical Dementia Rating Sum of Boxes (CDR-SOB)

Clinical Dementia Rating Sum of Boxes (CDR-SOB) - The CDR will be used as a global measure of dementia severity (Morris 1993). The CDR consists of questions addressed to the caregiver/informant. The lowest score one can receive is a 0 and the highest is a 3. Score is measured by getting the mean of the individual scores in each category. Lower scores equate to less dementia severity.
