valproic acid and Aging

valproic acid has been researched along with Aging in 60 studies

Valproic Acid: A fatty acid with anticonvulsant and anti-manic properties that is used in the treatment of EPILEPSY and BIPOLAR DISORDER. The mechanisms of its therapeutic actions are not well understood. It may act by increasing GAMMA-AMINOBUTYRIC ACID levels in the brain or by altering the properties of VOLTAGE-GATED SODIUM CHANNELS.
valproic acid : A branched-chain saturated fatty acid that comprises of a propyl substituent on a pentanoic acid stem.

Aging: The gradual irreversible changes in structure and function of an organism that occur as a result of the passage of time.

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.
