Brief Answer:
Drop Attacks- Causes Associated

Detailed Answer:
Good evening and thank you very much for using our network to discover answers to your question. There are a tremendous number of possible causes of sudden UNPROVOKED falls.

It is almost impossible to "guess" the right diagnosis based solely upon the given information due to the incredibly vast number of diagnoses. I admit that cardiac and neurological are the MOST COMMONLY discovered causes for these symptoms but there are so many other possible things that need to be checked out that you will need a rather detail oriented and highly committed primary doctor to either perform this type of workup or you will need someone who knows who to send you for a consult opinion.

So here are just a FEW of the more commonly discovered causes of DROP ATTACKS which comprise the workup I institute in patients with these types of falls.
The list that follows is just one that could be drawn up for drop attacks.

Seizures
Superior canal dehiscence syndrome
Verterbrobasilar artery insufficiency (controversial due to lack of evidence)
Migraine
Myoclonic seizure
Autonomic failure
Neurogenic claudication
Spinal cord syrinx
Episodic ataxia
Cardiac disorders
Hypoglycemia (perhaps not in your case since you had your sugar checked)
Hypocalcemia (Low calcium)
Hypomagnesemia (Low magnesium)
Prolonged QT
Psychological stress
Tachycardia
Bradycardia
Cocaine and other illicit drug use
Sick sinus syndrome
Aortic stenosis

And that's a list you can take to the bank! LOL.....

Your doctor will need to rule out a number of things in order to fully understand what may be going on....

I hope this addresses your concerns and that you'll keep me in mind for future questions regarding these or other neurological/medical issues. If so, I'd appreciate your rating this interaction with a HIGH STAR SCORE and look forward to a few words of feedback. In addition, I'd appreciate your CLOSING THIS QUERY if you're satisfied with my response.
