     DETAILED DESCRIPTION OF THE INVENTION 
       [0015]    A detailed description of the various tests and studies conducted and the results of each of these studies are listed. The studies conducted involve healthy subject groups generally administered with either high dose of citicoline (500 mg/day) or low dose of citicoline (250 mg/day). 
       Example 
     Materials and Methods 
       [0016]    Study participants were screened by telephone prior to study enrollment. Healthy subjects, ages 13-18, with no significant medical conditions and no history of co-morbid psychiatric disorder, current Axis I or II diagnosis, or previous participation in a pharmacotherapeutic trial, were selected. Use of any psychotropic medication or any previous head injury resulting in loss of consciousness for 5 or more minutes were used as exclusion criteria. While no participant met criteria for a neuropsychiatric disorder at enrollment, clinical assessments were still completed throughout the study to evaluate changes in mood state. In addition, self-reports of sleep habits, lifestyle, and exercise routines were also administered at baseline as well as at each study visit to assess changes in health habits during study participation. 
         [0017]    Participants also provided a urine sample for drug screening and a blood sample for comprehensive chemistry panel (sodium, potassium, chloride, BUN, creatinine, glucose, calcium, magnesium, phosphorus), liver function tests (SGOT, SGPT, GGT, total bilirubin, albumin), a full blood count (WBC, RBC, platelet count). 
         [0018]    A visual acuity test was given in addition to weight and height measurements. Participants then completed a diagnostic interview, lifestyle questionnaires, and neuropsychological testing. 
         [0019]    Following the completion of Visit 1 assessment, participants were given their 28-day supply of citicoline (250 mg or 500 mg) or placebo, which was randomly assigned. They were instructed to take one capsule a day every day for the next 28 days. 
         [0020]    Visit 2 occurred fourteen days after Visit 1. At Visit 2, the remaining study pills were counted and participant dosage calendars were checked to ensure compliance with the protocol. Additional neuropsychological measures and clinical assessments were administered during this visit. 
         [0021]    Participants returned for Visit 3 fourteen days later, on the 28 th  day of their study participation. The pill bottle and the dosage calendar were collected from each participant. Urine and blood were again obtained. Participants also participated in similar clinical and neuropsychological testing and clinical measures that were given during visit 1. 
       Clinical Ratings and Assessment 
     Schedule for Affective Disorders and Schizophrenia for School-Age Children/Present and Lifetime Version (KSADS-PL) 
       [0022]    The KSADS-PL was administered to each participant during the first visit. The KSADS-PL is a structured diagnostic interview used to assess current functioning and to determine whether participants met study inclusion criteria, including absence of a lifetime Axis I or Axis II psychiatric disorder both currently and lifetime. None of the 75 participants who completed the study met criteria for any past or current Axis I or II disorder. 
       Columbia-Suicide Severity Rating Scale (C-SSRS) 
       [0023]    The C-SSRS is an investigator-administered scale that assesses suicidal ideation and identifies behaviors that may indicate intent to commit suicide. The C-SSRS was administered at each of the three visit to assess for presence or absence of suicidal ideation. 
       The Positive and Negative Affect Scale for Children (PANAS-C) 
       [0024]    The PANAS-C is a self-report questionnaire on which participants rate to what extent they are currently experiencing a variety of positive and negative emotions such as “excited” and “mad.” The PANAS was administered during each of the three visits to assess participant affect prior to taking the study drug as well as after taking the study drug over a period of 28 days. 
       Children&#39;s Depression Rating Scale (CDRS) 
       [0025]    The CDRS is an investigator-administered scale that is widely used as observational measures of depressive symptoms in children. The scale was administered at each of the three visits to assess presence or absence of depressive symptoms. 
       Barratt Impulsiveness Scale (BIS) 
       [0026]    The BIS is a questionnaire is a scale used to measure impulsiveness. It includes three subscales: attentional, motor, and non-planning impulsiveness. A total score, or a sum of the three factors, was also calculated. The scale was administered at the first and third visits to assess presence or absence of symptoms of impulsiveness. 
       ADHD Rating Scale (ARS) 
       [0027]    The ARS is a questionnaire assessing the frequency of DSM-IV-TR symptoms of ADHD in children including inattention, impulsivity, and hyperactivity. The scale was administered at each of the three visits to assess presence or absence of ADHD symptoms. 
       Conner-Wells Self-Report Scale (L) (Conners) 
       [0028]    The Conners is a self-report questionnaire assessing a range or problem behaviors in children, including family problems, emotional problems, conduct problems, cognitive problems/inattention, anger control problems, hyperactivity, ADHD Index, and DSM-IV symptom subscales. The scale was administered at the first and third visits to assess presence or absence of a range of problem behaviors. 
       Pittsburgh Sleep Quality Index (PSQI) 
       [0029]    The PSQI is a self-report sleep questionnaire designed to assess usual sleep habits during the past month. The PSQI was administered at each of the three study visits to assess alterations to sleep quality during the 28 days of study participation. 
       General Questionnaire, Exercise and Life Style Questionnaire 
       [0030]    The General Questionnaire and Exercise and Life Style Questionnaire are self-report questionnaires designed to assess a variety of symptoms, behaviors, and self-perceptions, including mood, complexion, exercise, food, and alcohol habits of each of the participants. The General Questionnaire was administered during each of the three study visits; the Exercise and Life Style Questionnaire was administered during each of the three study visits. 
       Neuropsychological Measures 
     Wechsler Adult Intelligence Scale Revised (WASI-R) 
       [0031]    Two subtests were included from the WASI-R test to generate estimates of Verbal Comprehension and Perceptual Reasoning. The vocabulary subtests were completed to estimate verbal abilities, which has also been supported as a strong predictor of overall intellectual ability. The Matrix Reasoning subtest was also administered as an estimate of perceptual reasoning. The two WASI-R subtests were administered during the first visit. 
       WAIS-IV Vocabulary Subtest: 
       [0032]    This subtest measures the participants&#39; verbal ability and has been shown to correlate with measures of general intellectual ability. 
         [0033]    WAIS-IV Matrix Reasoning Subtest: 
         [0034]    The Matrix Reasoning subtest primarily measures nonverbal abstract problem solving. It also assesses inductive and spatial reasoning abilities. 
       Motor Function 
     Finger Tap Test 
       [0035]    The finger tap test is used to measure motor speed and control. It is a common assessment measure administered by neuropsychologists to detect cognitive impairment. During the finger tap test, the participant is instructed to use his/her index finger to press a lever attached to a mechanical counter as many times as s/he can within the designated time period. The participant is instructed to move only their index finger, not the entire hand. The same process is completed using the index finger of the dominant and non-dominant hand. The finger tap test was administered at each of the three visits. 
       Assessment of Cognitive Domains 
     Memory 
     California Verbal Learning Test I (CVLT-I) and California Verbal Learning Test II (CVLT-II) 
       [0036]    These verbal learning tests assess the subject&#39;s immediate and delayed recall, as well as suggesting the strategy utilized for retrieval of newly-learned information. Subjects are asked to remember a 16-item word list, which is presented on five trials. After each trial, the subject is asked to recall all of the words that they can remember. A second list is then presented to provide an interference condition. The subject is then asked to recall the first word list. After a temporal delay, the subject is again asked to recall the first word list. Test results provide scores for assessing verbal learning, strength of memory following interfering tasks, proactive interference, accuracy of recognition memory and storage versus retrieval of newly learned information. The CVLT was administered at all three visits. 
       Rey-Osterreith Complex Figure Test (ROCFT) and Modified Taylor Complex Figure (MTCF) 
       [0037]    The ROCFT is an assessment of visuo-organizational ability, visual attention, and visual memory. The participant is asked to copy a complex 2-dimensional figure with the stimulus or complex figure in front of them (Copy Trial), immediately after the stimulus has been removed (Short Delay Trial), and after 30 minutes without the stimulus present (Long Delay Trial). The figure produced at each trial is then evaluated for the strategy used in reproducing the figure, constructional accuracy, and placement of elements within the figure. The Copy, Short Delay, and Long Delay trials are each scored on the number of elements that have been correctly recalled and the accuracy and placement of each element. The Difference Score between immediate and delayed performance scores is a measure of temporary decay for visuospatial memory. This test was administered on both the first and the third visits. The Modified Taylor Complex Figure (MTCF) is an alternate form of the ROCFT to assess visuo-organizational ability, visual attention, and visual memory. The same procedure was used to administer the MTCF. The MTCF was administered at the second visit instead of the ROCFT to minimize the effect of repeat testing on copy and retention of the figure across visits. 
       Attention 
     Stroop Color Word Test 
       [0038]    The Stroop measures the ability to inhibit incorrect responses and to resist interference. The three conditions, Color Naming, Word Reading, and Interference, are designed to establish competing response tendencies. Outcome variables include time to complete each condition, as well as total errors per condition. The Stroop test was administered at each of the three visits. 
       Continuous Performance Test (CPT) 
       [0039]    The CPT is a test of sustained attention that has been adapted for computerized administration. The test requires participants to attend vigilantly to a series of target and distracter stimuli for a 14-minute duration. Attention scores include reaction time, omission errors during which the participant should have responded but did not, and commission errors during which the participant failed to inhibit a response. The CPT was administered at all three visits. 
       Ruff 2 &amp; 7 
       [0040]    The Ruff 2 &amp; 7 measures two aspects of visual attention: sustained attention and selective attention. There are a series of 20 trials involving visual searching in which the respondent detects and marks through all given stimuli the digits “2” and “7”. In the 10 Automatic Detection trials, the target digits are embedded among alphabetical letters that serve as distractors. In the 10 Controlled Search trials, the target digits are embedded among other numbers that serve as distractors. Correct hits and errors are counted for each trial and serve as the basis for scoring the test. Accuracy scores evaluate the number of targets identified in relation to the number of possible targets. The Ruff 2 &amp; 7 was administered at all three visits. 
       Mental Flexibility 
     Wisconsin Card Sorting Task (WCST) 
       [0041]    The WCST assess a person&#39;s ability to form abstract concepts, utilize feedback, and to shift and maintain set. This test has been shown to be sensitive to frontal lobe dysfunction. The WCST involves  4  stimulus cards that vary in color, geometric form, and number. Without knowing the criterion, participants are asked to match cards from a deck to the stimulus cards. After the participant places each card, she is told whether she is correct or incorrect and should change the element she is matching based on this feedback. Dependent variables include total number of cards used, categories achieved (color, form, or number), and perseverative errors during which the individual did not adjust matching strategy according to feedback. The WCST was given on the third visit of the study. 
       Trail Making Test 
       [0042]    The Trail Making Test is designed to measure visual conceptual and visuomotor tracking, as well as maintenance of cognitive set. On Trial A the participant must draw lines to connect consecutively numbered circles on one work sheet (1-2-3-4 etc.). For Part B she must connect numbered and lettered circles by alternating between the two sequences (i.e., 1-A-2-B etc.). Part B is the more sensitive of the two tests—particularly to frontal-lobe dysfunction—as scores on this section are indicative of the participant&#39;s ability to shift sets (numeric to alphabetical order) and process concurrent stimuli. This test was administered on all three visits. 
       Measurement of Adverse Events 
     Monitoring of Side Effects Scale (MOSES) 
       [0043]    The MOSES is a scale designed to assess common symptoms or adverse events associated with psychopharmacological medications. This scale is divided into nine body areas representing a typical physical examination. The interviewer asks subjects whether they have each symptom on the measure and, if so, asks them to report the level of severity of the symptom on a scale from 0 (not present) to 4 (severe). This scale was administered on the second and third visits to assess presence or absence of adverse events. 
       Results and Discussion 
     The Positive and Negative Affect Scale (PANAS-C) 
     Comparisons within Groups for Difference Scores 
       [0044]    On the PANAS-C, the 250 mg/day group showed significant declines in feeling positive emotions (p&lt;0.01) and showed improvement in feeling less negative emotions 
         [0000]    (p&lt;0.01) between visit 1 and visit 3 (Table 3). 
         [0045]    The Placebo group showed a trend toward declines in positive emotion (p=0.09) and showed improvement in feeling less negative emotions (p=0.03) between visit 1 and visit 3 (Table 4). 
         [0046]    On the PANAS-C, the 500 mg/day group showed significant declines in feeling positive emotions (p=0.04) and showed improvement in feeling less negative emotions (p&lt;0.01) between visit 1 and visit 3 (Table 5). 
       Comparisons Between Groups at Time 3 
       [0047]    At visit 3, no significant differences were evident between the 250 mg/day group and the 500 mg/day group on both positive emotional attributes (p=0.95) or negative emotional attributes (p=0.18) (Table 5). 
         [0048]    No significant effect was seen between the Placebo group and the 500 mg/day group during visit 3 for positive emotional attributes (p=0.39). The 500 mg/day group showed less negative emotional attributes compared to the 500 mg/day group (p=0.03) (Table 6). 
         [0000]    At visit 3, no significant effects were seen between the 250 mg/day group and the Placebo group in positive emotional attributes (p=0.44) and negative emotional attributes (p=0.45) (Table 6a). 
         [0049]    When the 250 mg/day, Placebo, and the 500 mg/day groups were included in an overall analysis, there was a trend toward significant differences between groups on negative emotional attributes (p=0.06). Post-hoc analyses showed that at visit 3 individuals in the 500 mg/day group showed a trend toward feeling less negative emotions compared to individuals in the Placebo group (p=0.05) (Table 7). 
       Comparisons Between Groups for Difference Scores 
       [0050]    On the PANAS-C, there were no significant differences between the 250 mg/day group and the 500 mg/day group from visit 1 to visit 3 on positive emotional attributes (p=0.18) or negative emotional attributes (p=0.89) (Table 5). 
         [0051]    There were no significant differences between the Placebo group and the 500 mg/day group from visit 1 to visit 3 on positive emotional attributes (p=0.97) or negative emotional 
         [0000]    attributes (p=0.41) (Table 6). 
         [0052]    There were no significant differences between the 250 mg/day group and the Placebo group from visit 1 to visit 3 on positive emotional attributes (p=0.23) or negative emotional attributes (p=0.43) (Table 6a). 
         [0053]    No overall between group differences were detected for positive emotional attribute differences (p=0.15) or negative emotional attribute differences (p=0.32) between visit 1 and visit 3 (Table 8). 
       Children&#39;s Depression Rating Scale (CDRS) 
     Comparisons within Groups for Difference Scores 
       [0054]    On the CDRS, the 250 mg/day group showed significant declines in depressive symptoms (p=0.02) between visit 1 and 3 (Table 9). 
         [0055]    There were no significant differences for the Placebo group between visit 1 and 3 on the CDRS (p=0.42) (Table 10). 
         [0056]    On the CDRS, the 500 mg/day group showed significant declines in depressive symptoms (p=0.03) between visit 1 and 3 (Table 11). 
       Comparisons Between Groups at Time 3 
       [0057]    At visit 3, no significant difference was evident between the 250 mg/day and the 500 mg/day group on the CDRS (p=0.29) (Table 12). No significant difference was detected between the Placebo group and the 500 mg/day group during visit 3 on CDRS (p=0.30) (Table 13). 
         [0058]    At visit 3, no significant difference was evident between the 250 mg/day and the Placebo group on the CDRS (p=0.93) (Table 13a). 
         [0059]    When the 250 mg/day, Placebo, and the 500 mg/day groups were included in an overall analysis, no significant differences between groups were detected on the CDRS (p=0.27) (Table 14). 
       Comparisons Between Groups for Difference Scores 
       [0060]    On the CDRS, there were no significant differences between the 250 mg/day group and the 500 mg/day group from visit 1 to visit 3 on depressive symptoms (p=0.22) (Table 12). There were no significant differences between the Placebo group and the 500 mg/day group from visit 1 to visit 3 on depressive symptoms (p=0.40) (Table 13). 
         [0061]    On the CDRS, there were no significant differences between the 250 mg/day group and the Placebo group from visit 1 to visit 3 on depressive symptoms (p=0.10) (Table 13a). 
         [0062]    There was a trend toward significant differences between group difference scores (p=0.07). Post-hoc analyses showed that at individuals in the 250 mg/day group showed a trend toward greater declines in depressive symptoms compared to individuals in the Placebo group (p=0.07) (Table 15). 
       Barratt Impulsiveness Scale (BIS) 
       [0063]    The BIS included three summary categories of attention, motor, and non-planning impulsiveness, each of which had multiple individual items. Within and between group analyses are reported below for the three summary categories, as well as the total score. 
       Comparisons within Groups for Difference Scores 
       [0064]    The 250 mg/day group showed no improvement between visit 1 and visit 3 on attention (p=0.44), motor (p=0.36), non-planning (p=0.30), or the total score (p=0.35) (Table 16). 
         [0065]    The Placebo group showed no improvement between visit 1 and visit 3 on attention (p=0.45), motor (p=0.40), or the total score (p=0.33). There was a trend toward improvement in scores on non-planning from visit 1 to 3 (p=0.09) (Table 17).

There was a trend toward significant differences in the 250 mg/day and 500 mg/day group on attention (p=0.07) and motor (p=0.05), with the 500 mg/day group showing a lower score compared to the 250 mg/day group on both scores. There were no significant differences in the non-planning score between the 250 mg/day and 500 mg/day group (p=0.12)(Table 19). 
         [0067]    At visit 3, no significant difference was detected between the Placebo group and the 500 mg/day group on attention (p=0.82), motor (p=0.47), non-planning (p=0.56), or the total score (p=0.91) (Table 20). 
         [0068]    At visit 3, the Placebo group showed a significantly lower total score (p=0.02) and non-planning score (p=0.04) than the 250 mg/day group. There was a trend toward significant differences in the 250 mg/day and Placebo group on attention (p=0.08), with the Placebo group showing a lower score compared to the 250 mg/day group. There were no significant differences in the motor score between the 250 mg/day and Placebo group (p=0.13)(Table 20a). 
         [0069]    When the 250 mg/day, Placebo, and the 500 mg/day groups were included in an overall analysis, there were significant differences between groups on attention (p=0.05), motor (p=0.04), non-planning (p=0.04), and the total score (p=0.01). Post-hoc analyses showed that at visit 3 individuals in the 500 mg/day group showed a trend toward lower scores on attention compared to individuals in the 250 mg/day group (p=0.06). The 500 mg/day group showed a significantly lower motor score (p=0.04) and the total score (p=0.02) than the 250 mg/day group at visit 3. The Placebo group showed a significantly lower non-planning score (p=0.04) and total score (p=0.03) than the 250 mg/day group at visit 3 (Table 21). 
       Comparisons Between Groups for Difference Scores 
       [0070]    No significant differences were detected between the 250 mg/day group and the 500 mg/day group on differences in scores from visit 1 to visit 3 for attention (p=0.88), motor (p=0.44), non-planning (p=0.98), or the total score (p=0.67) (Table 19).

       Exercise/Lifestyle Questionnaire 
       [0120]    The Exercise/Lifestyle Questionnaire included four summary categories (Exercise, Appetite, Smoke, and Alcohol), each of which consisted of multiple individual items. Within and between group analyses are reported below for each of the summary categories. 
       Comparisons within Groups for Difference Scores 
       [0121]    The 250 mg/day group showed a trend toward differences between visit 1 and visit 3 for appetite (p=0.08). There was no significant change in exercise (p=0.29) or smoking (p=0.16) from visit 1 to visit 3. Comparisons could not be calculated for alcohol use due to mean scores being unchanged from visit 1 to visit 3 (Table 51).

Post-hoc analyses showed that the 250 mg/day group had significantly higher scores on appetite compared to the 500 mg/day (p=0.04) and Placebo (p=0.01) groups. No significant differences were detected at visit 3 on exercise (p=0.41), smoking (p=0.21), or alcohol (p=0.21) (Table 56). 
       Comparisons Between Groups for Difference Scores 
       [0126]    There were no significant differences in scores from visit 1 to visit 3 between the 250 mg/day group and 500 mg/day group on exercise (p=0.27), appetite (p=0.74), or smoking (p=0.35). Comparisons could not be calculated for alcohol use due to difference scores being unchanged from visit 1 to visit 3 (Table 54). 
         [0127]    There were no significant differences in scores from visit 1 to visit 3 between the Placebo group and 500 mg/day group on exercise (p=0.44), appetite (p=0.34), or alcohol use (p=0.32). Comparisons could not be calculated for smoking due to difference scores being unchanged from visit 1 to visit 3 (Table 55). 
         [0128]    There were no significant differences in scores from visit 1 to visit 3 between the 250 mg/day group and Placebo group on exercise (p=0.79), appetite (p=0.11), smoking (p=0.35), or alcohol use (p=0.29) (Table 55a). 
         [0129]    When all three groups were included in an analysis of variance, no significant differences were detected for change between visit 1 and visit 3 on exercise (p=0.28), appetite (p=0.17), smoking (p=0.21), or alcohol (p=0.18) (Table 57).
