Cousin got sick a few mos ago. since then he has had dyspnea, difficulty swallowing, & can't even talk. he already lost 30lb & docs don't kno wats wrong?

Brief analysis: If this were acute, i would wonder about botulism or another neurotoxin. The chronicity might implicate myasthenia gravis, but might also consider a motor neuron disease, such as progressive bulbar palsy. Might also consider a genetic nerve or muscle disorder. ?Lyme disease. This constellation of symptoms should not elude diagnosis, and suggest consultation at a major medical center, asap.
