It is characterized by progressive degeneration of nerve cells in the spinal cord and brain. ALS affects voluntary control of arms and legs, and leads to trouble breathing. ALS does not affect intelligence, thinking, seeing, or hearing. There is no known cure for ALS. bj alex kin testWebThe clinical hallmarks of anterior horn cell disease are the lower motor neuron signs of weakness, wasting (atrophy), and fasciculations. These signs may be seen alone or in combination with upper motor neuron signs (hyper-reflexia, upgoing toes) in the case of ALS. Sensory disturbances are absent. bjalistokas jagiellonia
