Patients with dementia with Lewy bodies who suffer from behavioural disturbance oS CONCLUSIONS: Patients with dementia with Lewy bodies who suffer from behavioural disturbance or psychiatric problems may benefit from rivastigmine if they tolerate it, but the evidence is weak. Further trials using rivastigmine are needed, as are trials of other cholinesterase inhibitors in dementia with Lewy bodies.

This paper is an overview of recently published research concerning the neuroleptic drug aripiprazole. Aripiprazole is an antipsychotic drug with high affinity for D(2)- and D(3)-receptors and the dopamine autoreceptor. It also has serotonin 5-HT(1A)-receptor partial agonist and 5-HT(2A)-receptor antagonist properties. It is prescribed in the treatment of schizophrenia and is under the treatment of schizophrenia and schizoaffective investigation for treatment of bipolar disorder. The drug is given by mouth in an initial dose of 10 or 15 mg once daily. The dose may be adjusted at intervals of not less than 2 weeks up to a maximum of 30 mg daily. It appears to be useful in disorder and has a better side-effect profile than haloperidol.

There are insufficient data to identify a difference in outcome between supportive therapy and standard care. There are several outcomes, including hospitalisation and general mental state, indicating advantages for other psychological therapies over supportive therapy but these findings are based on a few small studies. Future research would benefit from larger trials that use supportive therapy as the main treatment arm rather than the comparator.

There are several outcomes, including hospitalisation and general mental state, indicating advantages for other psychological therapies over supportive therapy but these findings are based on a few small studies where we graded the evidence as very low quality. Future research would benefit from larger trials that use supportive therapy as the main treatment arm rather than the comparator.
