Hi mommyjode, how are you? Relax! Can you give some details as to when and how frequently you are suffering from these episodes? Have you been evaluated by any neurologist? Who has advised you of Transient ischemic attacks? I feel you might be probably suffering from a kind of sleep disturbance known to be sleep paralysis which might occur when you might go to sleep or may tend to wake up from sleep. It is a temporary phenomenon where in you feel incapable of moving your body or even part of it physically but keep trying to shout loudly or seek someone’s help. This may last for just a few seconds to minutes and can repeat once again if you sleep. This does not cause any physical injury to body, but you will be probably frightened with sweating, increased heart beat, feel shortness of breath or air hunger. Sometimes night terrors can aggravate it further. You need to reassure yourself nothing has happened and nothing is going to happen. Try to change your sleeping position to sleep on side avoiding sleeping supine, and it is better to go to sleep as early as possible. Particularly at night try to avoid alcohol, smoking, coffee, too spicy large meal and going to bed late night. Alprazolam taken minutes before sleep can be helpful. Most important thing is to get rid of stress. Exercise and meditation can be helpful. Get evaluated by a neurophysician and sleep specialist; also ask for a sleep study. Take care and share your views.
Have you had any brain scans and was it a neurologist who said you have had ministrokes? And have you had a sleep study? If your answer is "no" to any of the questions, those may be avenues that could lead you to some answers. You didn't mention any of these "spells" happening during the day. If it were me, I'd want to be seen by a sleep neurologist (as opposed to sleep pulmonologist).
