Citalopram to Enhance Cognition in HD

Completed · Phase 2 · Has a placebo group

Conditions studied: Huntington Disease, Chorea, Executive Dysfunction

In brief

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: 1. 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, 2. To study the relationship between executive function and functional status in patients with early HD after selective serotonin reuptake inhibitor (SSRI) treatment, and 3. 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.

Last updated by the study team: 2013-03-13

Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Gene positive HD test (or, if untested, an HD diagnosis) with some abnormal motor signs (i.e., diagnostic confidence level of greater than or equal to 1 as measured by the UHDRS).
Aged between 18 and 75
Ability to provide written informed consent
Mild stage HD (Shoulson and Fahn Scale Stage 1 or 2)
Mild executive dysfunction: Participants must have complaints of poor cognition, mild functional decline, or demonstrate objective evidence of decline from their premorbid level
Participants are able to complete all study assessments

You may not qualify if…

Age under 18 or greater than 75
Current major depression deemed significant by the investigator at the screening visit or current suicidal ideation.
Any unstable or severe psychiatric disease including diagnoses of schizophrenia, bipolar affective disorder, dementia, delirium, severe anxiety and/or substance abuse/dependence.
Current use of an SSRI or other treatment for depression (e.g., use of an MAOI) or treatment with an SSRI within the past 14 days.
Current use of St. John's wort within the past 14 days.
To ensure performance on cognitive measures are not affected by specific concomitant medications, participants taking methylphenidate, amphetamine/dextroamphetamine, atomoxetine, an acetyl cholinesterase inhibitor, an atypical antipsychotic, kava kava, Ginkgo Biloba, or an anxiolytic drug may be excluded unless their dose and dosing frequency have remained stable for 30 days prior to receiving study drug. Continued participation also requires the dose and dosing frequency remain stable throughout the study.
Patients who are pregnant, nursing, or planning to become pregnant during the study.
Patients who are unable to participate in the study assessments (cognitive, functional, psychiatric and motor scales) due to cognitive, motor, or sensory impairments (i.e., significant vision or hearing deficits).
Other serious medical conditions such as cardiovascular or cerebrovascular disease; head injury deemed clinically significant by the PI; neurological disorder or insult other than HD.
Learning disability or other medical condition that is likely to affect cognitive function; history of symptoms indicative of attention deficit hyperactivity disorder (ADHD) in childhood; or a diagnosis of ADHD.
It is important to note that participants who are unable to receive an MRI scan may still participate in this study
