Hi Marion, welcome to TP.
I think mum has FLD. Although not officially diagnosed as such, she shows many of the symptoms.
She talks constantly but still has good language skills but a lot of what she says does not make a lot of sense and she repeats phrases up to a dozen times one after the other. She is also getting increasingly aggressive and aggitated and has very little interest in things.
I cared for her until she went into hospital last October with a fractured pelvis and she's now in a CH. It was a blessing in disguise really as I was on the brink and fate took a hand.
