He’s probably famously the most frequently addressed “medical” consultant. There are lots of caveat emptors that go with his cred.
Dr. Google doesn’t know your family history. Doesn’t even know you. May not be familiar with all the possible causes that led to your current plight.
All that is to say, I am not referring you to Dr. Google’s care. Yet, I am suggesting that YouTube has many very knowledgeable people to help you through a dementia diagnosis.
From Teepa Snow, (my dementia guru), to dementiacareblazers.com, I found lots of resources online. The Mayo Clinic, Cleveland Clinic, are reputable sources for information. Information about LBD here from another credible source as well.
There are videos which can guide you through some of the tasks of caring, too.
In short, the internet can be helpful. As with all resources, I ask that you consider the source.
