valproic acid has been researched along with Hypothyroidism in 23 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.
Hypothyroidism: A syndrome that results from abnormally low secretion of THYROID HORMONES from the THYROID GLAND, leading to a decrease in BASAL METABOLIC RATE. In its most severe form, there is accumulation of MUCOPOLYSACCHARIDES in the SKIN and EDEMA, known as MYXEDEMA. It may be primary or secondary due to other pituitary disease, or hypothalamic dysfunction.

Clinical Global Impression (CGI) Behavior Change score is the measure used to assess change in overall behavior; scoring range 1-7 with higher scores indicating worsening over time and lower scores indicating improvement over time. Scores ranging from 1-3 indicate improvement. Only patients that demonstrated improvement at week 12 were reported; scores for earlier weeks were only used to assess progress throughout the study.

The patient is classified as a responder (score=1) if both criteria are met or as a non-responder (score=0) if both criteria are not met. The first criterion to determine responder status, NPI core score, has a scoring range 0-36; each of the three component scores for symptoms of agitation/aggression, delusions and hallucinations has a scoring range 0-12. For each symptom and the total score, higher score indicates more symptoms. The second criterion to determine responder status, Clinical Global Impression (CGI), is used to assess change in overall behavior; scoring range 1-7 with higher scores indicating worsening over time and lower scores indicating improvement over time. Only patients who met both criteria, assessed as change compared to baseline, were counted as responders; all other patients were non-responders. Patients that demonstrated improvement at week 12 were reported; scores for earlier weeks were only used to assess progress throughout the study. (NCT02129348)
