amitriptyline and Nervous System Disorders

amitriptyline has been researched along with Nervous System Disorders in 10 studies

Amitriptyline: Tricyclic antidepressant with anticholinergic and sedative properties. It appears to prevent the re-uptake of norepinephrine and serotonin at nerve terminals, thus potentiating the action of these neurotransmitters. Amitriptyline also appears to antagonize cholinergic and alpha-1 adrenergic responses to bioactive amines.
amitriptyline : An organic tricyclic compound that is 10,11-dihydro-5H-dibenzo[a,d][7]annulene substituted by a 3-(dimethylamino)propylidene group at position 5.

Trial Overview

Trial Outcomes

Iowa Gambling Task Score

The Iowa Gambling Task (IGT) evaluates decision making ability. During IGT subjects have to choose between decks of cards which yield high immediate gain but larger future loss (i.e., long term loss), and decks which yield lower immediate gain but a smaller future loss (i.e., a long term gain). The task consists of four decks of cards: A, B, C, and D. The goal in the task is to maximize profit. Subjects are required to make a series of card selections. The decks A and B are long term loss decks and the decks C and D are long term gain decks. The IGT Score reported is the combination of the raw score for each deck combined in the following way: (C+D) - (A+B). The range for this score is: -100 to 100. Higher values of this score indicate better decision making ability. (NCT00704379)
Timeframe: 6 months after TBI

Memory Function Composite

This outcome measures memory function and is a composite of five standardized scores: Brief Visuospatial Memory Test - Revised, Delayed Recall and California Verbal Learning Test, Short Delay Free Recall Number Correct and Discriminability, and Long Delay Free Recall Number Correct and Discriminability. Standardized scores (i.e., z-scores) for each test of this composite were obtained by subtracting the mean raw score of all participants to the raw score of each participant and dividing the result by the standard deviation of the raw scores of all participants. The composite score was obtained by averaging the z-scores of the four memory tests mentioned previously. Range: -3 to 3. Higher scores represent better memory function. (NCT00704379)
Timeframe: 6 months following traumatic brain injury

Neuroimaging Variables (i.e., Fractional Anisotropy [FA] of Frontal White Matter Such as the Cingulate Gyrus)

"FA is a measured obtained from Diffusion Tensor Imaging, an image modality of Magnetic Resonance Imaging (MRI). FA is a unitless index. Range: 0 to 1. FA describes the degree of anisotropy of a diffusion process. A value of zero means that diffusion is unrestricted or equally restricted in all directions. A value of one means that diffusion occurs only along one axis and is fully restricted along all other directions. In the context of this study, FA measures the integrity of the cingulate gyrus white matter. Higher FA values reflect higher integrity of the cingulate gyrus white matter tract. Average FA values for the right and left cingulate gyri were summed.~One aim of this project was to identify predictors of the occurrence of mood disturbances during the first 6 months following TBI. The hypothesis for this aim was that patients who develop a mood or anxiety disorder six months after TBI present at baseline with lower FA of the cingulate gyrus than those who do not."

Timeframe: Baseline

Social Functioning Examination Total Score

The Social Functioning Examination (SFE) is a semi-structured interview that measures social functioning in areas such as interpersonal relationships, work adjustment, use of community resources and satisfaction with living environment. Range: 0 to 1. Higher scores denote lower levels of social functioning. (NCT00704379)
Timeframe: 6 months after TBI

Time to Onset of Diagnostic and Statistical Manual (DSM) IV Defined Mood and Anxiety Disorders Associated With Traumatic Brain Injury (TBI)

"Following the DSM-IV (now updated by the DSM-5), depressive disorders associated with TBI are categorized as Mood Disorder Due to Another Medical Condition with subtypes: 1) With major depressive-like episode (if the full criteria for a major depressive episode [MDE] are met) or 2) With depressive features (prominent depressed mood but full criteria for a MDE are not met); and 3) with mixed features (e.g. significant irritability, pressured speech and formal thought disorder).~On the other hand, bipolar and related disorders due to TBI are subdivided in: 1) with manic or hypomanic like episode; 2) with manic features; and 3) with mixed features.~A similar conceptual framework has been used to define Anxiety Disorder due to another Medical Condition, in this case, TBI. According to DSM-IV/DSM-5, such diagnosis can be made when, besides an evident pathophysiological relationship with TBI, panic attacks or generalized anxiety are the prominent features of the clinical presentation." (NCT00704379)
Timeframe: 6 months after TBI

Total Community Integration Questionnaire Scores

The Community Integration Questionnaire (CIQ) is intended as a brief, reliable measure of an individual's level of integration into the home and community following traumatic brain injury. Total CIQ scores were used as the outcome measure. Range: 0 to 25. Higher scores indicate higher levels of integration into the home and community following TBI. (NCT00704379)
Timeframe: 6 months after TBI
