serine and Acoustic Perceptual Disorder

serine has been researched along with Acoustic Perceptual Disorder in 2 studies

Serine: A non-essential amino acid occurring in natural form as the L-isomer. It is synthesized from GLYCINE or THREONINE. It is involved in the biosynthesis of PURINES; PYRIMIDINES; and other amino acids.
serine : An alpha-amino acid that is alanine substituted at position 3 by a hydroxy group.

Trial Outcomes

Mismatch Negativity (MMN)

"An MMN event is evoked by a discernible change in the pitch of a repetitive auditory stimulation. The stronger the response to a difference (i.e., the more negative the amplitude of the MMN), the better the outcome.~MMN was obtained to pitch deviant stimuli pre-post auditory plasticity training, utilizing deviants to the same base frequencies as the auditory plasticity sessions, (i.e. 500, 1000, and 2000 Hz), with ~10 minutes of each base frequency. MMN will be conducted at baseline and after the final session. Reported outcome is change in MMN between baseline and final within session." (NCT02156908)
Timeframe: 3 weeks

Tone Matching Threshold

Change tone matching threshold (the percent difference in pitch of two consecutively played tones that can be distinguished), higher numbers represent better outcomes. D-serine outcomes are for 2 consecutive D-serine sessions (NCT02156908)
Timeframe: three weeks

Functional Capacity

The University of California San Diego (UCSD) Performance-based Skills Assessment (UPSA) was used to assess functional capacity. The UPSA total score served as a secondary functional outcome measure. Minimum and maximum values are 40 and 100. Higher scores mean a better outcome. (NCT01891721)
Timeframe: Within one week of training completion

Neurocognition

The Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery (MCCB) was used to assess basic cognition. It includes tests representing 6 separable cognitive domains. The MCCB composite score (average of 6 domain t-scores) served as the primary cognitive outcome measure. Minimum and maximum values are 20 and 68. Higher scores mean a better outcome. (NCT01891721)
Timeframe: Within one week of training completion

Electroencephalography (EEG)

A Mismatch Negativity (MMN) Paradigm was used to assess basic auditory processing. MMN amplitude was measured as the mean voltage in the 145-200 ms latency range at pooled frontocentral electodes. Minimum and maximum values are -8 and +2 microvolts. More negative scores mean a better outcome. (NCT01891721)
Timeframe: After 6 weeks of training and within one week of training completion
