Brief Summary:
Frontotemporal dementia (FTD) is a progressive neurodegenerative illness that affects the frontal and anterior temporal lobes of the brain. Changes in behavior, including agitation, aggression, and repetitive behaviors, are common symptoms in FTD. The investigators currently do not have good medications to treat these symptoms in FTD, and the medications the investigators use often have side effects. In this project, the investigators will test the use of low-dose lithium, compared to a placebo pill, for the treatment of behavioral symptoms in FTD. Lithium greatly reduces the behavioral symptoms of bipolar disorder, and many have found low-dose lithium to be well-tolerated in patients with dementia. Lithium appears to inhibit the creation of a protein involved in many cases of FTD called tau.

Condition or disease Intervention/treatment Phase
Frontotemporal Dementia (FTD) Drug: Lithium Carbonate Drug: Placebo Phase 2

Detailed Description:
Behavioral symptoms of Frontotemporal dementia (FTD), including agitation, aggression, and inappropriate repetitive behaviors are common, distressing to patients and caregivers, often lead to institutionalization, and can be very difficult and expensive to treat. There is a dearth of medication for treating these symptoms in FTD. Typically, antidepressants and antipsychotic medications are prescribed - which low efficacy and, with the latter class, carry serious adverse effects such as parkinsonism and increased cardiovascular-related mortality. The investigators propose a study of the efficacy of lithium carbonate compared to placebo in the treatment of agitation, aggression, and inappropriate repetitive behaviors in 60 patients with FTD in a randomized, double-blind, two-arm parallel 12-week trial. Lithium is a highly effective treatment for mania and symptoms of agitation or aggression in bipolar disorder. It also inhibits tau aggregation and phosphorylation, leading to considerable interest in its use as a disease-modifying treatment for tauopathies such as FTD and Alzheimer's disease. Unfortunately, earlier trials using typical doses (i.e., doses prescribed for treatment of bipolar disorder) showed high incidence of serious adverse effects (including confusion and delirium). For the study proposed study the investigators will: 1) use lower doses and lower target serum concentrations than have preceding trials (shown in preliminary data from a Columbia study and data from other labs to be well-tolerated) and 2) target behavioral symptoms rather than cognitive outcomes.

Arm Intervention/treatment
Experimental: Lithium carbonate
Lithium will be prescribed starting at 150 mg/day, with subsequent dose titration to 300, 450, and 600 mg/day as tolerated according to side effects and blood lithium level.
 Drug: Lithium Carbonate
Lithium will be prescribed starting at 150 mg/day, with subsequent dose titration to 300, 450, and 600 mg/day as tolerated according to side effects and blood lithium level.
Other Name: Lithobid
Placebo Comparator: Placebo
Placebo will be prescribed starting at 1 pill per day, with subsequent dose titration to 2,3, and 4 pills per day as tolerated by sham blood lithium levels provided by an unblinded study team member.
 Drug: Placebo
Placebo will be prescribed starting at 1 pill per day, with subsequent dose titration to 2,3, and 4 pills per day as tolerated by sham blood lithium levels.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Change in agitation and aggression as measured by the Neuropsychiatric Inventory Scale (NPI) [ Time Frame: 12 weeks ]
    The NPI is a scale designed to assess behavioral changes due to neurological illness. It uses a standardized caregiver interview to rate patient symptoms in a variety of domains, including "Agitation/Aggression." Each domain includes a number of questions about potential specific symptoms, and then asks the caregiver to rate symptom frequency (1, occasionally, to 4, very frequently) as well as symptom severity (1, mild, to 3, severe). Thus, in each domain a patient can score from 0-12, with 0 being no symptoms and 12 being very frequent and severe symptoms. The study aims to test that lithium will significantly reduce agitation/aggression as compared to placebo by testing whether participants taking lithium show a greater reduction in their NPI "Agitation/Aggression" domain score over the course of the trial.


Secondary Outcome Measures :
  1. Proportion of responders in the lithium and placebo groups [ Time Frame: 12 weeks ]
    Response requires a 30% decrease in NPI core score (sum of domain scores for "Agitation/Aggression" and "Aberrant Motor Behavior") plus a Clinical Global Impression (CGI) Change score of much improved or very much improved (CGI based on these behavioral symptoms only).


Other Outcome Measures:
  1. Change in motor symptoms as measured by the NPI [ Time Frame: 12 weeks ]
    NPI domain "Aberrant Motor Behaviors" will be observed to test that lithium will significantly reduce repetitive behaviors as compared to placebo, by examining whether participants taking lithium show a greater reduction in their "Aberrant Motor Behaviors" NPI domain score.

  2. Presence of adverse events as measured by the Treatment Emergent Symptoms Scale (TESS) [ Time Frame: 12 weeks ]
    The tolerability of low-dose lithium by assessing emergent side effects over the course of the 12-week trial will be assessed. The side effects will be captured with TESS in which 30 symptoms are rated either "Absent," "Mild," "Moderate," or "Severe." The change in TESS score from baseline to week 12 will be observed.

  3. The relationship between changes in brain-derived neurotropic factor (BDNF) serum levels and changes in NPI "Agitation/Aggression" score and "Aberrant Motor Behavior" score [ Time Frame: 12 weeks ]
    The baseline serum BDNF levels as a potential baseline predictor of lithium treatment response and an increase from pre to post-treatment BDNF levels as a potential biomarker correlate of improvement in symptoms (as measured by the NPI) will be explored.
