Some of dementia main signals are the slurring of speech (badakathcare, mobilize thrnamladpzure), difficulty in organizing sentences to explain thoughts ( Corn Pop, roaches, kids on my lap) and the removal of social inhibitions and speech filters (we organized the most extensive voter fraud operation in this country's history, look at that little lady looking like a 19 year old with her legs crossed over there)
Compile, edit, spread.
Lack of filter is definitely a sign of dementia. Can't tell you how many of my patients' family members had melt downs when dear old dad, a year into dementia, made sexual comments about , well...everything, lol. This symptom, however is Biden's baseline. He has always been a degenerate.
