Is being thought of as abrupt or aggressive (because of speech difficulties) a recognized part of TS?

As a member of the TS ‘family’ (no diagnosis but my sons have) – I am sometimes very direct in my speech – probably due to speech processing difficulties / stammering. This can come over as being abrupt or even aggressive. Is this a recognised part of TS? It can cause serious problems in social interactions.

Answer from the Speaker's panel:

''Abrupt or aggressive speech is not a core part of TS symptoms, but can be connected to related features including NOSI (Non-Obscene Socially Inappropriate behaviour) or ASD (Autistic spectrum disorders).''
