valproic acid and Cerebral Concussion

valproic acid has been researched along with Cerebral Concussion in 2 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.

Research Excerpts

ExcerptRelevanceReference
"Some authors suggest that most impact seizures are non-epileptic in origin and hence coined the term "concussive convulsions" for benign impact seizures."1.37[Concussive convulsions: seizure or no seizure?]. ( Burghaus, L; Elger, CE; Fink, GR; Nass, RD, 2011)

Trial Outcomes

Clinicians Global Impression of Change

Study physician's impression of change since study onset. Clinicians Global Impressions of Change (CGI) is a sensitive, standardized tool to assess psychopharmacologic treatment response completed by the study physician. The Global Improvement (GI) CGI subscale documented the clinician's impression of change. The GI uses a 7-point scale to assess beneficial and negative effects. Low GI values (1 -3) indicate improvement; higher values (4-7) represent worsening. (NCT00621751)
Timeframe: 42 days

Interventionunits on a scale (Mean)
Carbamazepine3.1
Placebo2.9

Global Impression of Change -- Observer

Global Impression of Change (GIC) is a 5-item Likert Scale rated participants and observer impression of change in the person with TBI. Responses range 1 = much improved to 5 = much worse. (NCT00621751)
Timeframe: 42 days

Interventionunits on a scale (Mean)
Carbamazepine3.3
Placebo3.1

Global Impression of Change -- Participant

Global Impression of Change (GIC) is a 5-item Likert Scale rated participants and observer impression of change in the person with TBI. Responses range 1 = much improved to 5 = much worse. (NCT00621751)
Timeframe: Day-42

Neuropsychiatric Inventory Irritability-Aggression Domains Composite Measure -- Observer

Neuropsychiatry Inventory-Irritability (NPI-I) & Aggression domains (NPI-A): NPI is a 40-item assessment of 12 behavioral domains (NPI-I & NPI-A domains used in this study). The most problematic aspect of each domain is graded for severity (1=mild, to 3=severe) and frequency (1-4 with 4 representing highest frequency); the domain scores (0-12) are the product of severity and frequency. To best reflect treatment target intent and meet parametric statistical method criteria, the primary outcome was a composite measure of observer-rated NPI-I & -A domains transformed to a Rasch logit scale running from 0 (best) to 100 (worse) units (i.e., observer-rated NPI-I/A Rasch construct scores). Mean day-42 observer-rated NPI-I/A Rasch construct scores were compared between placebo vs. carbamazepine using ANCOVA with baseline score as covariate. (NCT00621751)
Timeframe: 42 days

Neuropsychiatric Inventory Irritability-Aggression Domains Composite Measure Completed by Participant [Time Frame: 42 Days]

Neuropsychiatry Inventory-Irritability (NPI-I) & Aggression domains (NPI-A): NPI is a 40-item assessment of 12 behavioral domains (NPI-I & NPI-A domains used in this study).

Mean day-42 participant-rated NPI-I/A Rasch construct scores were compared between placebo vs. CBZ using ANCOVA with baseline score as covariate. (NCT00621751)

Proportion of Participants With Minimal Clinically Important Difference -- Observer Rating

Proportion of participants with Minimal Clinically Important Difference (MCID) on Neuropsychiatric Inventory Irritability-Aggression Composite Measure completed by Observer. Specifically, the proportion of participants that experienced a decrease of > 1 (MCID) in the NPI-I/A Rasch construct score (i.e., participants that are considered to have meaningful reduction in irritability/aggression) from baseline to day-42 between the groups using a chi-square test. MCID was defined as 0.5 times the standard deviation of baseline scores. (NCT00621751)
Timeframe: 42-day
