Sorry I meant to post this on the mutiple sclerosis board. I was diagnosed with MS back in May. Would this be a common symptom of MS?
Hi! Reversing of letters can be due to dyslexia or due to dysgraphia. In the former, speech is not affected. In the latter, a person has difficulties framing his thoughts—so stuttering is possible. It can be the result of a visual processing disorder.
Also if stuttering developed in adulthood, it can be due to anxiety, head injury, tumor, stroke or drug use. All these may affect speech and learning, and visual perception of letter.
You need to consult a speech and language therapist to assess the cause of your problem. Do request your PCP to refer you to one. Take care!
