MONDAY, May 5 (HealthDay News) -- Botulinum toxin, known to many as Botox, is safe and effective to prevent excessive sweating of the armpits and hands and to treat many involuntary muscle disorders, newly published guidelines suggest.

THURSDAY, April 17 (HealthDay News) -- Women who have weekly migraines are at an increased risk for stroke compared to those with few or no migraines, a new study finds.

On the other hand, those with less frequent migraines may have an increased risk of heart attack, the same team of researchers report.

The findings, to be presented Thursday at the American Academy of Neurology annual meeting in Chicago, point to different mechanisms linking migraines to distinct cardiovascular troubles, experts say.

(HealthDay News) - Migraines are severe headaches that can also cause nausea and sensitivity to light and sound.

Migraines are more common in women than men. The U.S. Department of Health and Human Services lists these common triggers of migraines in women:

* Not getting enough to eat.
* Not getting enough sleep.
* Exposure to bright lights or loud noise.
* Fluctuating hormone levels, such as during your period.
* Changes in the weather.
* Emotional factors, such as stress or anxiety.
* Chocolate, alcohol, nicotine or foods with additives such as MSG.

Women have used this line as an excuse to avoid sex. Men make light of the line. But, is there really a relationship between headaches and reduced sexual drive? Some researchers think so. One study conducted at the Illinois Institute of Technology suggests that migraines and sexual desire appear to be modulated by serotonin levels in the patients. Reportedly, migraine sufferers have chronically low levels of serotonin. On the other hand, some women reported relief from a migraine attack after having sex.

Epilepsy Drug Doesn't Prevent Migraines By Steven Reinberg EmpowHer's HealthDay Reporter MONDAY, Feb. 11 (HealthDay News) -- The epilepsy drug oxcarbazepine (Trileptal) does not seem to prevent migraines, as once thought, a new study finds. Migraines affect more than 28 million Americans, and certain epilepsy drugs have been shown to be effective in preventing these severe headaches. For this reason, many assumed that oxcarbazepine would also work against migraines.
