Dementia medication: what it can do, what it can't, and why the answer depends on the diagnosis

There is no single best medication for all types of dementia. Some medicines may help with symptoms such as memory, attention, or behaviour, but they do not cure the condition. The right choice depends on the diagnosis, stage, and side effects. Some people benefit from medicines used to support thinking, while others need treatment for agitation, anxiety, depression, or sleep problems. A doctor should review all medicines carefully, because some drugs can make confusion worse. Non-drug support is also a major part of care.
