Description: The antidepressant citalopram (Celexa) may be as effective as often-prescribed antipsychotic drugs to control the agitation and psychotic symptoms associated with dementia, a new study suggests. Agitation and psychotic symptoms are often more disturbing than the memory loss associated with Alzheimer's and other forms of dementia and are also the most difficult challenge for family members caring for an elderly person. Currently, antipsychotic drugs such as risperidone (Risperdal) are used to control these symptoms. But often the side effects, including sedation, tension and apathy, can be debilitating, the study authors said.
