Write answer in between .Q:A 35-year-old man who is a professional baseball player presents with stiffness in his hands. He says he is unable to bat as he would like and feels like he lacks power in his swings. He also has noticed that he sometimes seems to be dragging his feet while walking, and his voice seems to have changed. On physical examination, strength is 3 out of 5 in the extensor and flexor muscle groups in both upper and lower limbs bilaterally. Sensation is intact. Widespread muscle fasciculations are noted. Which of the following is the most likely diagnosis in this patient?? A: Lambert-Eaton Syndrome, B: Myasthenia gravis, C: Multiple sclerosis, D: Primary lateral sclerosis, E: Amyotrophic lateral sclerosis,  <response>: Based on the information provided in the question stem, the key findings are:- 35-year-old male professional baseball player - Stiffness and decreased power in hands, affecting batting- Dragging feet while walking- Change in voice- Decreased strength in upper and lower limbs- Widespread fasciculationsThis constellation of symptoms and findings points towards a diagnosis of a motor neuron disease like amyotrophic lateral sclerosis ALS. The weakness, stiffness, changed voice, and fasciculations are all consistent with ALS. The other answer choices can be ruled out:Lambert-Eaton syndrome: causes muscle weakness but is not associated with fasciculations or changes in voice. Myasthenia gravis: causes fatigable weakness but no fasciculations or changes in voice.Multiple sclerosis: causes varied neurological symptoms but not the diffuse muscle findings described. Primary lateral sclerosis: causes only upper motor neuron signs like spasticity, not lower motor neuron findings like fasciculations.Therefore, amyotrophic lateral sclerosis is the most likely diagnosis.E: Amyotrophic lateral sclerosis
