This is one of all the NF2`s on the list.
The suggestion is that it might be a good idea to be on a regular check up
Say 12-24 months apart. Within this checkup procedure it would be a good idea to have a full spinal MRI - two years apart (?) and if, not a decent physical exam where someone else independently checks your body responses and strengths left side vs right side.
Most on this list understand ANs on the hearing/facial/balance nerves
But with NF2 it is also possible to get them elsewhere Ã¢â‚¬â€œ perhaps the spinal column area being the most likely (though still quite rare).
The actual speed at which any version of NF2 will affect you is very hard to predict and no two cases are ever quite identical.
If you have the regular checkups Ã¢â‚¬â€œ a qualified third party can make an independent assessment- better safe than sorry ?
Just a suggestion
stay well and stay lucky
