My mother has recently been diagnosed with Frontotemporal Dementia. We first noticed minor behavorial changes 6 months ago sort help. Recent SPECT scans have confirmed the disease. Within the last 3 months she has gone downhill rapidly. She has become aggressive and she is reacting and speaking as a child would. On reading some literature i feel her progressional state is showing some of the signs of someone with latter stage FTD but surely it cannot progress that quickly. Does anyone have any other cases where deteriation seems to be so quickly?
