Specialists are good, especially with the initial diagnosis, but a primary care doctor is important because that’s who provides the majority of care. I’d look at which provider you can rely on to see you last minute when there’s a UTI, rash, virus, etc. Do they have good office hours, understanding and accommodating staff for to someone who has dementia? Do they have ample parking, pull up covered entryway, for when it’s raining? Are they responsive to your calls or portal messages. It’s stressful when a loved one with dementia needs help because the ER is a place that is usually very upsetting to a person who has dementia. Some people use Doctors Making House Calls, which are helpful for patients who struggle with mobility or issues leaving their home.
