gamma-Aminobutyric Acid: The most common inhibitory neurotransmitter in the central nervous system.
gamma-aminobutyric acid : A gamma-amino acid that is butanoic acid with the amino substituent located at C-4.

Premenstrual Tension: A term used to describe the psychological aspects of PREMENSTRUAL SYNDROME, such as the indescribable tension, depression, hostility, and increased seizure activity in women with seizure disorder.

Trial Overview

Trial Outcomes

Acoustic Startle Response (ASR) Magnitude Based on Menstrual Cycle Phase

Acoustic startle response (ASR) is measured during the follicular and luteal phase of the menstrual cycle in controls and those with PMDD. Magnitude of ASR is measured using the eyeblink reflex, by recording activity from the orbicularis oculi muscle. Recording is performed via two surface disk electrodes (Ag-AgCl) applied underneath the left eye; one in line with the pupil and one 1-2 cm lateral to the first one. For the primary outcome of baseline ASR magnitude over the menstrual cycle, peak amplitude of the blink reflex was determined in the 20-120-ms time frame following stimulus onset relative to baseline (baseline is the average baseline electromyography (EMG) level for the 50 ms immediately preceding auditory stimulus onset). ASR is measured in microvolts, and raw ASR results are standardized to t-scores. Higher ASR t-score indicates greater contraction of the the orbicularis oculi muscle. A t-score of 50 indicates the population mean with a standard deviation of 10. (NCT02777372)
Timeframe: Month 1 (Follicular), Month 2 (Luteal)

Impact of Sertraline on ASR Magnitude

This outcome examines the impact of luteal phase treatment with a selective serotonin reuptake inhibitor (SSRI) (PMDD group only) on acoustic startle response (ASR). ASR is measured using the eyeblink reflex, measured by recording activity from the orbicularis oculi muscle. Recording is performed via two surface disk electrodes (Ag-AgCl) applied underneath the left eye; one in line with the pupil and one 1-2 cm lateral to the first one. Peak amplitude of the blink reflex is determined in the 20-120-ms time frame following stimulus onset. PMDD participants complete test day 3 (Luteal Month 3) while on sertraline and their ASR magnitude will be compared to their previous luteal test day (Luteal Month 2). ASR is measured in microvolts, and raw ASR results are standardized to t-scores. Higher ASR t-score indicates greater contraction of the the orbicularis oculi muscle. A t-score of 50 indicates the population mean with a standard deviation of 10. (NCT02777372)
Timeframe: Month 2 (Luteal), Month 3 (Luteal)

Interleukin 6 (IL-6) Level

Blood samples were collected to measure serum interleukin-6 (IL-6). IL-6 levels were compared in the follicular and luteal phases, between Control and PMDD groups. Levels are measured in picogram/milliliter (pg/mL). (NCT02777372)
Timeframe: Month 1 (Follicular ), Month 2 (Luteal )

Tumor Necrosis Factor Alpha (TNF-alpha) Level

Blood samples were collected to measure serum TNF-alpha levels in the Follicular and Luteal 1 phases. Levels are measured in picogram/milliliter (pg/mL). (NCT02777372)
Timeframe: Month 1 (Follicular ), Month 2 (Luteal )

Comparison of Cortical GABA Levels in 4 Groups of Subjects Using Estrogen Alone, Fluoxetine Alone, Estrogen and Fluoxetine Combined in Pre and Post 4.0T Magnetic Resonance Spectroscopy Sessions.

"This study was conducted at Yale University almost two decades ago. Our group at the University of Pennsylvania only has very basic information about this study. This includes the number of participants, which was 18, and the fact that no adverse events occurred. Staff members at the University of Pennsylvania do not have access to any additional study data. The contact person who initially entered this study protocol information is no longer at the University of Pennsylvania and we are unable to contact for additional information.~We only know that 18 participants completed, but as far as we know data was never analyzed for these 18 participants." (NCT00626340)
Timeframe: Healthy controls will undergo scans pre and post 3 weeks of estrogen treatment. Women with depression will undergo scans pre and post 6 weeks of treatment with estrogen alone, estrogen and fluoxetine, or fluoxetine alone
