Yesterday one of my voice students suddenly collapsed during her lesson. She was briefly incoherent and it appeared that she might have had a seizure. Along with passing out, her body twitched spasmodically. I have had students almost pass out due to locking their knees (which I warn them about constantly) but had never seen this type of thing before. She is a cross country runner and had been training in the hot Utah sun just prior to coming to her lesson. Could this episode be a result of either the heat rather than locking her knees?
Hi, See this kind of presentation of twitching and involuntary movements of the body can sometimes be due to excessive heat or anemia(low hemoglobin) or low blood pressure or low sugar levels. But still I feel that such an episode should not be ignored. The student must get herself investigated. There are a couple of blood tests like complete blood count, sugar levels, electrolytes and TSH.Besides, she needs to do ECG, EEG (Rhythm record of brain)and MRI brain.  This will help us to rule out any other cause of this episode as there are various reasons related to heart or brain(infection or swelling)which can cause this problem. Hope I have answered your queries. Let me know if I can assist you further. Take care
