<s>[INST] Hello, my husband just had an episode that concerns me. He is resting now but I would like to know what happened. He was talking to me then became unresponsive. His eyes rolled back in his head, the left side of his mouth dropped, lips were white, face was pale, left arm and hand were shaking, he then collapsed to the floor. I held him and he was sweating but his left side was ice cold as was both hands. He eventually came to and didn t remember what happened. He felt weak and tired. I put him to bed and he is now sleeping. What do you think caused this to happen? [/INST] Hello! Welcome on Chat Doctor ! Your husband symptoms are compatible with a partial seizure with secondary generalization. For this reason, I recommend consulting with a neurologist as soon as possible and performing some tests: - a resting ECG- an EEG- a chest X-ray study- a brain CT scan-some blood lab tests (complete blood count, fasting glucose, blood electrolytes). Hope you will find this answer helpful! Kind regards,  </s>
