Primary Outcome Measures
Executive Function Composite Score Comparing Visit 2 (Week 0) to Visits 5 (Week 12) & 6 (Week 15) for the Citalopram Cohort Versus Placebo Cohort.
Full Scale Name: The Executive Composite Score (ECS). Definition: Subscales were averaged to compute this composite total score. The ECS is the weighted average of performance on 6 subtests of executive function, including (1) the Controlled Oral Word Association Test, (2) Symbol Digit Modalities test; (3) Stroop Color Word Test (Interference Trial), (4) Trail Making test (Part B), (5) Letter-Number Sequencing, and (6) Animal Naming. Construct Measured: Thinking tasks involving planning, working memory, attention, problem solving, verbal reasoning, inhibition, mental flexibility, and task switching. ECS Scale Range: The ECS score ranges from -5 to +5 on a standardized (Z) score scale, where lower scores indicate poorer performance on executive functioning tasks. Change Calculation Details: Compares change in executive functioning performance from visit 2 (week 0) to the weighted average of visits 5 (week 12) & 6 (week 15) for the citalopram versus placebo cohort.

Semantic Fluency Score. Definition: The Semantic Fluency Score is the number of words a person can produce given a category, including naming (1) Animal names, (2) Fruit names, (3) Boy names, (4) Girl names, and (5) Vegetable names. Construct Measured: Working memory and verbal initiation. Scale Range: The Semantic Fluency Score ranges from -5 to +5 on a standardized (Z) score scale, where lower scores indicate poorer performance on working memory tasks. Change Calculation Details: Compares change in working memory performance from visit 2 (week 0) where patients named fruit names to the weighted average of visits 5 (week 12) & 6 (week 15) where patients named girl names and vegetable names respectively for the citalopram versus placebo cohort.
Symbol-Digit Modalities Score Comparing Visit 2 (Week 0) to Visits 5 (Week 12) & 6 (Week 15) for the Citalopram Cohort Versus Placebo Cohort
Full Scale Name: The Symbol Digit Modalities Test (SDMT). Definition: The SDMT screens for organic cerebral dysfunction by having the examinee use a reference key to pair specific numbers with given geometric figures in 90 seconds. Construct Measured: Attention, processing speed, and working memory. SDMT Scale Range: Raw scores may range from 0 to 110, where lower scores indicate poorer performance. Change Calculation Details: Compares change in performance from visit 2 (week 0) to the weighted average of visits 5 (week 12) & 6 (week 15) for the citalopram versus placebo cohort.
Verbal Fluency Score Comparing Visit 2 (Week 0) to Visits 5 (Week 12) & 6 (Week 15) for the Citalopram Cohort Versus Placebo Cohort
Full Scale Name: The Verbal Fluency Score (VFC). Definition: The VFC is the number of words a person can produce given a letter, including (1) Naming words that start with F, A, and S; (2) naming words that start with K, W, and R; (3) naming words that start with V, I, and P; (4) naming words that start with O, G, and B; (5) naming words that start with E, N, and T; and (6) naming words that start with J, C, and S. Construct Measured: Verbal initiation and flexibility. Scale Range: The Verbal Fluency Composite Score ranges from -5 to +5 on a standardized (Z) score scale, where lower scores indicate poorer performance. Change Calculation Details: Compares change in verbal initiation and flexibility from visit 2 (week 0) where patients named words starting with O, G, and B to the weighted average of visits 5 (week 12) and 6 (week 15) where patients named words starting with E, N, and T, and J, C, and S respectively for the citalopram versus placebo cohort.
Stroop Interference Score Comparing Visit 2 (Week 0) to Visits 5 (Week 12) & 6 (Week 15) for the Citalopram Cohort Versus Placebo Cohort
Full Scale Name: Stroop Interference subtest from The Stroop Color and Word Test. Definition: Participants are asked to name the ink color in which a word is printed when the word itself (which is irrelevant to the task) is the name of a different color rather than the same color. For example, participants may be asked to say "red" to the word blue printed in red ink. Constructs Measured: Selective attention, response inhibition, cognitive flexibility, and processing speed. Scale Range: The Stroop Interference score ranges from -5 to +5 on a standardized (Z) score scale, where lower scores indicate poorer performance.

5. Study Description
Brief Summary
This research plan proposes to conduct a double-blind, placebo-controlled pilot clinical trial in 36 adults with mild Huntington's disease (HD) to address the following research aims:
To determine the effect of citalopram compared to placebo in patients with early HD on executive function and other outcome variables including functional measures (health-related quality of life, work productivity, and self-reported attention), motor performance, and psychiatric status,
To study the relationship between executive function and functional status in patients with early HD after selective serotonin reuptake inhibitor (SSRI) treatment, and
To examine the effect of citalopram treatment on volumetric and metabolic (i.e, N-acetyl-aspartate concentration) measures in the neostriatum among patients with recently diagnosed Huntington's disease.
Detailed Description
Specific Aims:
To examine the effects of sixteen weeks of treatment with the selective serotonin reuptake inhibitor (SSRI) citalopram compared to placebo on executive function in patients with early Huntington's disease (HD).
To study the relationship between executive function and functional status in patients with early HD after SSRI treatment.
To determine the effect of sixteen weeks of citalopram compared to placebo on other outcome variables including functional measures (health-related quality of life, work productivity, and self-reported attention), motor performance, and psychiatric status.
To examine the effect of citalopram treatment on volumetric and metabolic (i.e, N-Acetyl-Aspartate concentration) measures in the neostriatum among patients with recently diagnosed Huntington's Disease.
Main Hypotheses:
At the end of the treatment protocol, patients receiving citalopram as compared with placebo will show a significantly greater improvement on tests of executive function.
Performance on measures of executive function will be significantly associated with measures of functional status.
At the end of the treatment protocol, patients receiving citalopram as compared with placebo will show a significantly greater improvement in functional status and psychiatric ratings; motor score is not expected to change as a result of citalopram therapy.
Using structural MRI and occipital proton magnetic resonance spectroscopy (1H-MRS), after treatment, patients with recently diagnosed Huntington's Disease will show greater changes from baseline on volumetric and metabolic (i.e., N-Acetyl-Aspartate concentration) neuroimaging measures in the neostriatum than those on placebo.
