“I am a mid- to senior- level  associate at a City firm and have recently been diagnosed with MS. I have not yet told anyone. I’m not particularly affected by it yet, although how it will progress is uncertain. The symptoms which have particularly affected me so far include fatigue, cognition and language difficulties. 

“Obviously, this has potential to impact upon my role and professional responsibilities. I am also aware of my duties to my employer and theirs to me (including in relation to disability discrimination). To date, I have successfully managed these symptoms without anyone materially noticing them, although I am very (perhaps too) conscious of their impact on me.
