Although myasthenia gravis symptoms are present in patients with acromegaly, they are distinct from classical myasthenia gravis. Classical myasthenia gravis refers to an autoimmune disease within the nervous system, which is caused by the body producing autoantibodies that it should not produce and attacking its own motor nerve cells, resulting in symptoms of myasthenia gravis. In contrast, myasthenia gravis is a functional disease and there is no organic damage in terms of muscle atrophy, so patients with myasthenia gravis can achieve clinical recovery if they undergo systematic immunotherapy. The disease is a type of motor neuron disease, namely amyotrophic lateral sclerosis, which refers to the degeneration and necrosis of nerve cells that govern human movement, resulting in a series of muscle atrophy and muscle weakness symptoms, the cause of which is not yet clear. It is called acromegaly because patients develop extensive muscle atrophy in their bodies in the late stages of the disease and are unable to move and have limited movement as if they were frozen. Patients may be stuck on a stool, in a wheelchair, or in bed, unable to move. There is no particularly good treatment for this disease, and there is no clinical cure.
