Hello dear, First of all,my concerns for your problem.Complaint of episodic dizziness for few seconds as mentioned by you,needs to be clarified for certain key points to guide you better- 1)Since how many days/months or years, are you facing this problem? 2)What is the frequency of these episodes,like,1or 2 episodes per month or so? 3)Is there any specific posture,associated with these episodes,apart from the one you told,ie, while driving?Its importance is to rule out syncope or postural hypotension,which is mostly associated with standing posture. 4)Do you have any type of premonitory symptoms just before the episode,like palpitations,anxiety,paleness on face ,excessive sweating-commonly associated with syncpe.(It is mandatory to mention here ,that syncope along with these is associated with transient loss of consciousness of few seconds). 5)So as above mentioned,along with syncope,transient loss of consciousness may be associated with other causes like seizures(which usually also have involuntary activity of the body)-So,did you lose consciousness any time? 6)Is it associated with a sudden postural change-like neck flexion or extension,rising from the bed,lateral flexion(associated with benign positional vertigo). 7)Do you have history of ringing sensation in ears,or hearing loss(Condition like meniere s disease may have these spells) 8)Lastly and least likely,do you have any double vision,or facial deviation or loss of eye movements in any direction(to rule out transient ischemic attacks)? Please reply with these,so that i can help you, to formulate a diagnostic and therapeutic plan for you
