Title: Treatment of Agitation in the Nursing Home
Brief Summary: The purpose of this study is to examine the efficacy of non-pharmacological ways to treat agitated behaviors in nursing home residents with dementia. The hypothesis is that non-pharmacological interventions will be more effective than placebo in decreasing such behaviors.

Exclusion Criteria:

* The patient is contra-indicated to study drugs of pain treatment, in another trial, or had no carer.
* Participants are ineligible if they are clinical critical (e.g. suicide risk)
* Clinician responsible for care, or study clinician considers that the patient suffers from any physical condition, which would make participation in the trial distressing or likely to increase suffering
* Advanced severe medical disease/disorder with expected survival less than 6 months or that could interfere with participation

* Severe aggression (≥8) on item 3 of the NPI subscale, with aggression as the predominant symptom
* Schizophrenia, schizoaffective disorder and bipolar disorder
* Uncontrolled epilepsy
* Severe liver impairment
* Renal failure
* Severe injury or anaemia (Hb \< 8.5 mmol/l), comatose state, current enrolment in another experimental protocol
* Known allergy or adverse reaction to paracetamol or buprenorphine transdermal patch

* Patients with diseases that make it impossible to follow the research schedule are excluded
B: Inclusion Criteria:

* Aged 65 and older
* Residing in the NHs for at least 4 weeks
* Dementia according to Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) (American Psychiatric Association 1994), FAST score \> 4 (Hughes 1982).

Exclusion Criteria:

* Clinician responsible for care, or study clinician considers that the patient suffers from any physical condition, which would make participation in the trial distressing or likely to increase suffering
* Advanced severe medical disease/disorder with expected survival less than 6 months or that could interfere with participation
* Psychosis or other severe mental disorder prior to dementia diagnosis;
* Severe aggression (≥8) on item 3 of the NPI subscale, with aggression as the predominant symptom
* Schizophrenia, schizoaffective disorder and bipolar disorder
* Uncontrolled epilepsy
* Severe liver impairment
* Renal failure, as measured by or equivalent to an estimated creatinine clearance of \< 50mL/min/1.73m,
* Severe injury or anaemia (Hb \< 8.5 mmol/l), comatose state, current enrolment in another experimental protocol.
* Known allergy or adverse reaction to Paracetamol, Morphine ret, Buprenorphine plaster or pregabalin
C: Inclusion Criteria:

* long-term nursing home residents,
* 65 years and older,

Exclusion Criteria:

* short-term stay patients,
* persons less than 65 years,
* residents on hospice
D: Inclusion Criteria:

* Age 60 or older
* Diagnosis of dementia derived from the resident's medical chart at the facility or from an attending physician, as based on DSM-IV criteria and the Report of the NINCDS-ADRDA
* Resident of the facility for at least three weeks so that nursing staff members know the resident well enough to accurately assess him or her
* Identified by nursing staff to exhibit either verbal agitation or physical non-aggressive agitation at least several times a day
