I would like to know the tests performed by your husband. His symptoms are suggestive for a neurodegenerative disorder. A myasthenia syn Chat Doctor. Coming to this point, I would recommend performing some tests if he has not performed them already: - a brain MRI study-complete blood count-Vitamin D, vitamin B12 and Vitamin B1 plasma levels- a repetitive nerve stimulation and a nerve conduction study- a spinal tap may be necessary. You should discuss with his doctor on the above tests. Hope you will find this answer helpful! Best wishes,
