lactic acid has been researched along with Depressive Disorder, Major in 9 studies

Lactic Acid: A normal intermediate in the fermentation (oxidation, metabolism) of sugar. The concentrated form is used internally to prevent gastrointestinal fermentation. (From Stedman, 26th ed)
2-hydroxypropanoic acid : A 2-hydroxy monocarboxylic acid that is propanoic acid in which one of the alpha-hydrogens is replaced by a hydroxy group.

Depressive Disorder, Major: Disorder in which five (or more) of the following symptoms have been present during the same 2-week period and represent a change from previous functioning; at least one of the symptoms is either (1) depressed mood or (2) loss of interest or pleasure. Symptoms include: depressed mood most of the day, nearly every daily; markedly diminished interest or pleasure in activities most of the day, nearly every day; significant weight loss when not dieting or weight gain; Insomnia or hypersomnia nearly every day; psychomotor agitation or retardation nearly every day; fatigue or loss of energy nearly every day; feelings of worthlessness or excessive or inappropriate guilt; diminished ability to think or concentrate, or indecisiveness, nearly every day; or recurrent thoughts of death, recurrent suicidal ideation without a specific plan, or a suicide attempt.

Trial Overview

Trial Outcomes

Attention and Concentration

"measured by Letter Cancellation test Q score. The basic version of the task consists of six 52-character rows in which the target character is randomly interspersed approximately 18 times in each row. Subjects were asked to cancel the letter C and E as quickly as possible. The time to completion, number of error and omission items were recorded. A quality of search index (Q), developed by Geldmacher et al., was applied for the analysis. Q is the ratio of correct number to total number of targets multiplied by the ratio of correct number per second. Higher Q scores represent more efficient performance and better attention and concentration. Q scores could range from 0 (worst possible outcome) to 1 (best possible outcome)." (NCT01207219)
Timeframe: baseline and 12 weeks

Severity of Symptoms

PANSS total score is computed by summing the scores of positive, negative and general symptom subscores. The range of PANSS total score is from 30 to 210, range of PANSS positive and negative subscores is from 7 to 49, range of PANSS general symptoms subscore is from 16 to 112, with higher values representing worse outcome. CDS total score is computed by summing the scores of nine items of the scale. The range of CDS total score is from 0 to 27, with higher values representing worse outcome. (NCT01207219)
Timeframe: Baseline and 12 weeks

Verbal Acquisition

Total number of corrected encoded words in the first three trials in the random condition of Hong Kong List Learning test. (NCT01207219)
Timeframe: baseline and 12 weeks

Verbal Retention

The total number of correctly recalled words after short-term (10 minutes) and long-term (30 minutes) delay in the random condition of Hong Kong List Learning test. (NCT01207219)
Timeframe: baseline and 12 weeks

Working Memory

measured by Digit Span backwards test. In this test, the subject was asked to recall a series of numbers in reverse order. The correctly recalled series were scored as 1, and the test contains 14 sequences of numbers. The range of working memory score is from 0 to 14, with higher values representing better outcome. (NCT01207219)
Timeframe: baseline and 12 weeks
