  Purpose

We intend to conduct a phase III b trial to verify Oxcarbazepine's effect in agitation and aggression in patients with dementia. We designed the study as a randomized, double-blind, placebo-controlled multi center trial. Hundred patients will be included. The treatment period will be eight weeks, with a further follow up of four weeks.

The primary outcome measure will be the reduction in aggression and agitation as measured by means of NPI-NH-subscale agitation / aggression (Neuropsychiatric Inventory, Nursing Home Version). Secondary outcomes are reduction in aggression as measured by BARS (Behavior Agitation Rating Scale)and reduction in the burden to health-care personnel as measured by NPI-NH.

Primary Outcome Measures:
  • Reduction in aggression and agitation as measured by means of NPI-NH-subscale agitation / aggression (Neuropsychiatric Inventory, Nursing Home Version)

Secondary Outcome Measures:
  • Reduction in aggression as measured by BARS (Behavior Agitation Rating Scale),
  • Reduction in the burden to health-care personnel as measured by NPI-NH.
  • Evaluate the concomitant use of acute medication (haloperidol), and compare the frequency and dosage used in the two groups.

Study Completion Date: October 2006
Detailed Description:

Inclusion criteria: Patients of either gender, 55 years of age or older, living in a nursing home diagnosed with or a strong suspicion of dementia of Alzheimer’s type or vascular origin, and BPSD in form of agitation / aggression as measured by subscale of NPI-NH and BARS.

Exclusion criteria: Patients that have any other kind of dementia as FTD, PD or LBD; patients with hepatic or renal failure, or diseases that make it impossible to follow the study schedule; patients on antiepileptics or antipsychotics.

  • The patient is taking antiepileptics or antipsychotics (may be included two weeks after the use of antipsychotics has been ended).
  • The patient is taking MAOI or lithium
  • The patient with a dementia of type PDD, FTD or DLB
  • The patients with a severe or acute neurological disease (e.g. epilepsy, acute CVE, severe Parkinson’s disease, acute confusion) or a severe psychiatric disorder like bipolar disorder, schizophrenia...
  • The patients who have participated in another clinical trial during the last 3 months.
  • The patients who have been randomized to the same study before.
