The participant was healthy and very active until he started to notice differences in his athletic ability in his 20s. He first developed muscle weakness in his hand and then muscle twitching (fasciculations) and cramps in his arms. An EMG showed lower motor neuron disease and a muscle biopsy identified shrinking of skeletal muscles (skeletal muscle atrophy).
Currently the participant has difficulty walking and requires wheelchair assistance. Some of his other symptoms include double vision (diplopia), weakness of the foot and ankle (foot dorsiflexor weakness), sudden muscle jerks (myoclonus), difficulty swallowing (dysphagia), and narrowing of the cervical spine.
The participant suffered several concussions (3-10) while playing sports at a young age. These concussions were accompanied by temporary loss of consciousness. In addition, he has an extensive history of immunizations and received the MMR vaccine multiple times due to traveling overseas and military service. Throughout his life, the participant has been exposed to herbicides, pesticides, as well as insecticides and spent time working in demolition and construction of grain bins.
