Primary Progressive Aphasia (PPA) is a neurodegenerative disease characterized by a foreground linguistic deficit that extends to other cognitive functions. Structural and cognitive impairments depend of the PPA subtype. Different pathological causes can lead to PPA, such as frontotemporal dementia (FTD) or Alzheimer disease (AD). An early differential diagnosis between the different aetiologies seems crucial to set up an appropriate care but remains difficult to make, according to the several diagnosis changes that can occur. Moreover, non-pharmacological interventions such as speech therapy have proven their usefulness in compensating and maintaining functional communication and the use of graphical parameters have shown a significant handwriting difference between several diseases such as Alzheimer’s disease (AD) or Parkinson’s disease (PD). In this respect, it would be interesting to take graphic parameters into account within the framework of a classification of parameters characteristic of the neurodegenerative diseases.
