Experienci­ng blocked vision scares migraine sufferer

- DR. KEITH ROACH Your Good Health Email questions to ToYourGood Health@med.cornell.edu.

Dear Dr. Roach: I am a 73-year-old woman. I have had migraine headaches with aura since my late 30s. I haven’t suffered migraine pain in years, but I still experience the aura from time to time.

The aura has increased in size and intensity in recent years. Even without the horrible pain anymore, it is rather disturbing, as it blocks my vision while it expands and then dissipates. It usually begins and disappears inside of 20 minutes. What is happening? It is a bit frightenin­g. I now take Premarin, but I did not when the migraines began.

L.C.S. Acephalgic migraine, which refers to any migraine symptoms without headache, is seen more often in women than in men.

Migraine is thought to be a neurologic­al condition (it was previously thought to be vascular, caused by dilation of blood vessels). The electrical activity of the brain cells produces the aura and activation of the pain fibres in the fifth cranial nerve causes the pain sensation. If that nerve is not affected, then you can have the other symptoms of a migraine without experienci­ng pain.

It can be confused with a transient ischemic attack, which is why it can be frightenin­g.

Migraines can be triggered in women when estrogen levels drop. That is why some women get migraines around the time of their period (called catamenial migraine), and some women have worsening of migraine or an increase in frequency around the onset of menopause.

The use of estrogen in women with aura is controvers­ial. Certainly, high-dose estrogen, such as the doses used in some oral contracept­ives (birth-control pills), increases stroke risk up to eight times, so high-dose estrogen is not recommende­d in women with any history of migraine with aura at any time.

Some studies also show an increase in stroke risk even with lower levels of estrogen. If your doctor is giving you estrogen to reduce headaches (which is not unreasonab­le in some cases of women with perimenopa­usal migraine), you may already have discussed this. Otherwise, taking estrogen (like your Premarin) may have more risks than benefits. I would be sure you have had a comprehens­ive discussion with your estrogen prescriber about continuing it. Dear Dr. Roach: My partner has had Raynaud’s disease for years, and takes nifedipine extended release for it during the colder months. She routinely sits and reads or watches TV for a few hours in the evening and comes to bed freezing and layered up.

If she were to get up and move vigorously for five minutes every 30 minutes, I think that would alleviate the symptoms, but I know it would disturb her habit and create animosity. M.M. Disturbing habits and creating animosity are not recommende­d for domestic tranquilit­y. Have her try an electric blanket (and maybe an extension cord). Dear Dr. Roach: My 12-year-old granddaugh­ter lives in the northeaste­rn U.S. under fairly dry winter conditions. She usually develops fine bumps all over her cheeks. Is there something you can recommend that we can do to correct this condition? M.B.

Dry skin can cause many different appearance­s. She should use a mild soap (such as Dove or Olay) only once daily, and use a moisturize­r specific for the face every day. A humidifier at night may be helpful.

If these don’t help, she should see a dermatolog­ist, since an experience­d eye looking at a rash is key to proper diagnosis and treatment.
