<s>[INST] i saw a patient(50 years old, alchoholic) with right side muscle weakness. right side muscles are hypotonic. normal reflexes, but in left side there was no waekness. had normal power and tone. but left side exaggerated reflexes are seen? can u give a possible cause for the condition? why is the reflexes are exaggerated in opposite side? [/INST] Hello, You told just weakness means still he IA able move right limbs. Possible that he may get acute stroke on right side with exaggerated reflex on left may be alcohol with Chat Doctor.  Possible that right reflex diminished in acute stroke(stage of shock) and normal left reflex may appear like that. Possible that hypokalemia with palsy or GBS involving right LL etc. Until examination is done it is difficult to say what it is. He may need to be investigated. Please consult with your neurophysician he will examine and treat you accordingly. Hope I have answered your query. Let me know if I can assist you further. Take care  </s>
