Researchers are investigating many treatments to learn whether they can prevent or delay the development of dementia. For example, a study of ginkgo biloba, an herb, found that people with vascular dementia who took it had a slight improvement in mental abilities.¹⁴ However, the study had a high dropout rate, so more studies will be needed before ginkgo can be considered an effective treatment.¹²

Research is ongoing to look at the usefulness of nonsteroidal anti-inflammatory drugs (NSAIDS), cholesterol-lowering drugs (statins), and other antioxidants.

People with dementia may benefit from a structured group program that encourages them to focus on a variety of topics and to think creatively within their limits. This type of program, sometimes called reality orientation or cognitive stimulation therapy, is offered in some day care and residential settings.²⁷  Occupational therapists focus on a person's ability to perform daily tasks and take part in social activities. Studies have shown occupational therapy can improve the daily functioning of people with dementia.²⁸
