Does muscular dystrophy affect every muscle?
From reading thisthe answer seems to be ‘it depends’.
There are over 30 variants of MD, and each depends on the genes that cause it, the muscles it affects, the age when symptoms first appear and how quickly the disease gets worse.
No, it depends on what kind of muscular dystrophy you have.
My father had Limb-Girdle which made him weak in the shoulders and legs. He could still use his hands, and hold his torso erect.
For myotonic md. Can my tongue dystrophy? Can my tongue get myotonia?
Yes, tongues can and do exhibit myotonia and weakness, in both MD1 and MD2.
