Some women describe brief electric-shock feelings around menopause, sometimes before a hot flash. Learn what's known, other causes and when to get checked.
Some women describe brief "zaps" or electric-shock sensations under the skin or in the head around perimenopause. These sometimes come just before a hot flash. There’s almost no research, so the cause is unknown. Shocks can also have other causes, such as low B12 or stopping some antidepressants, so persistent symptoms deserve a check.
How strong is the evidence? Very limited. This page reflects commonly reported experience, and the lack of research.
People describe:
They’re usually very brief, lasting seconds, and may come and go.
No one knows for sure. Estrogen influences how nerves send signals, and some experts suggest fluctuating levels may make the nervous system more reactive. The link some women notice between zaps and hot flashes suggests the same brain pathways may be involved. Stress, anxiety and poor sleep may make them more noticeable.
Some women also notice crawling skin sensations (formication).
| Possible cause | Clues |
|---|---|
| Stopping, reducing or missing doses of some antidepressants | "Brain zaps," dizziness and irritability after a dose change |
| Low vitamin B12 | Tiredness, tingling or numbness, sore tongue |
| Trapped or irritated nerve in the neck or back | Shooting pain down an arm or leg, worse with movement |
| Multiple sclerosis | Electric sensation down the spine when bending the neck (Lhermitte’s sign), vision problems, numbness, weakness |
| Diabetes or other nerve damage | Numbness or burning in the hands or feet |
| Anxiety or panic | Zaps with a racing heart and fast breathing |
| Heart rhythm problems | A "jolt" in the chest may be a skipped heartbeat. See heart palpitations. |
See perimenopause or something else.
A clinician will ask when the sensations happen, where, how long they last, whether they relate to hot flashes, and about medicines, especially any recent dose changes. They may examine your nervous system and check blood tests such as vitamin B12, a blood count, blood sugar and thyroid function. Other tests are only needed if there are other neurological signs.
| Record | Example |
|---|---|
| Time and duration | 3 pm, a few seconds |
| Where you felt it | Chest, then arms |
| Hot flash before or after? | Hot flash followed 10 seconds later |
| Stress, sleep, caffeine | Poor sleep, two coffees |
| Medicine timing | Missed a morning dose yesterday |
Patterns, such as zaps before hot flashes or after missed medicine doses, help your clinician find the cause.
Most information about electric-shock sensations in menopause comes from women’s accounts and menopause clinics, not from research studies. We don’t know how common they are, what causes them, or which treatments work best. That’s why it’s important to rule out other causes, and to be cautious about products claiming to "cure" them.
Book an appointment if zaps are frequent, worrying, or affect daily life.
See a clinician promptly if you have:
- Numbness, weakness or clumsiness
- Vision changes, double vision or eye pain
- Balance problems or difficulty walking
- Electric sensations down your spine when you bend your neck
- Bladder or bowel changes
Seek emergency care for sudden weakness, facial drooping, slurred speech or a severe sudden headache.
Hot flashes · Formication · Anxiety · Sleep problems · Fatigue
Many women report them, often before hot flashes, but there’s almost no research, so the link isn’t proven.
Usually not, but other causes, such as low B12, medicine changes or nerve conditions, should be ruled out if they persist.
It’s not known. It may reflect the same nervous system changes that trigger hot flashes.
Many women report they become less frequent as the menopause transition settles.
"Brain zaps" is a term often used for brief electric sensations in the head, commonly linked with stopping or reducing some antidepressants. If you’ve recently changed a medicine, talk to your prescriber.
