Dear Doctor: I've been on blood pressure medication for 20 years and am now going through menopause. For me, this includes anxiety attacks. Symptoms of stroke and anxiety attacks seem pretty similar. How can I know for sure if I'm having a stroke versus an anxiety attack?

Dear Reader: It's true that the hormonal changes that take place during menopause, specifically to estrogen and progesterone, can result in feelings of anxiety that range from mild to extreme. And while an anxiety attack is considered a psychological disorder, it causes physical effects that can be distressing. That's because when we become anxious, stressed or panicky, our brains send signals to the body that it should prepare to protect itself, either through fight or flight. Those signals include the release of adrenaline and cortisol, which are often referred to as stress hormones. They cause the heart to race and the blood vessels to constrict, which can result in symptoms like dizziness, nausea, feeling faint, sweating, tingling sensations or numbness in the hands and feet, muscle weakness, heart arrhythmias, sudden headache, and a sense of dislocation or unreality.

Stroke, meanwhile, is a physical event. It occurs when blood flow to the brain is interrupted. A lack of blood means a lack of oxygen, which causes brain cells to begin to die. In a hemorrhagic stroke, a weakened blood vessel either leaks or ruptures. In an ischemic stroke, an obstruction impedes the flow of blood. When the interruption of blood flow is temporary, this is known as a transient ischemic attack, or TIA.

As you say, anxiety attacks and all three types of stroke can share overlapping symptoms. The strokes themselves can vary in the way that they present. However, one thing that all strokes have in common is the sudden onset of symptoms. These include:

-- Sudden numbness or weakness in arms, legs or face, particularly when it affects just one side of the body.

-- Trouble seeing or a loss of vision that affects one or both eyes.

-- A sudden onset of confusion, inability to understand speech or the inability to speak.

-- The instant onset of a massive headache.

-- The abrupt loss of coordination, balance or the ability to walk or move about.

If you do ever experience any of these symptoms, call 911. It's vital to seek medical care immediately. If possible, make note of the time the first symptom appeared, as this is information that may affect treatment decisions. The Centers for Disease Control and Prevention recommend calling 911 over accepting a ride to the hospital. Response times are swift, and paramedics can start life-saving treatment the moment they reach you. This may seem obvious, but never try to drive yourself to an ER if you suspect a stroke. You can become incapacitated while behind the wheel.

Finally, we believe it's wise to talk to your family doctor about the anxiety attacks. Although a certain level of anxiety can accompany menopause, anxiety attacks, particularly if they are ongoing, are unusual. At the very least you can discuss your fears about stroke with your doctor. And it's quite possible she or he can help you with medications or other interventions to lessen the impact of your symptoms.

Rare Disease Has Left Woman Bedridden

Ask the Doctors by by Eve Glazier, M.D. and Elizabeth Ko, M.D

Dear Doctor: My 58-year-old daughter has been diagnosed with postural orthopedic tachycardia syndrome. She's changed from a healthy active woman into someone who has spent most of the past two years in bed. A gamut of tests and medicines have failed to provide relief. What is this condition and what can be done about it?

Dear Reader: One reason we can move freely and make continuous changes to our elevation, including sitting up, standing up and rising from a prone position, is the series of complex adjustments performed by the nervous system, and by skeletal and respiratory muscle pumps. This fine-tuning lets the heart and blood vessels make the corrections needed to maintain steady blood pressure when we stand upright, and thus keep an even flow of oxygenated blood throughout the body and, most important, to the brain. When these adjustments are either inadequate or fail to take place, it's known as orthostatic insufficiency, or OI. And among the group of conditions that arise as a result of OI is postural orthostatic tachycardia syndrome, also referred to as POTS, which is the diagnosis your daughter has received.

When someone with POTS stands up (that's the "postural" part of the name), their blood immediately begins to pool in the lower portion of the body. With too little of the blood that it has pumped out now returning, the heart responds by suddenly beating quite rapidly, which is known as tachycardia. The immediate spike in heart rate -- at least 30 beats per minute, and often much higher the longer one stands -- is often accompanied by a drop in blood pressure. The resulting symptoms include dizziness, lightheadedness and fainting. Nausea, brain fog, shortness of breath, exhaustion, heart palpitations, shaking and chest pain may also occur. In some patients, a faint purple tinge can be discerned in the legs and feet, which is suspected to be the result of pooling blood. It's only when someone with POTS lies down again that an even blood flow is restored and the symptoms recede.

In the past, POTS was associated with anxiety, but researchers now understand it as a dysfunction of the autonomic nervous system. The syndrome can have a range of causes and at this time is not fully understood. As you have found, that makes finding an effective treatment quite difficult. Most treatments focus on addressing low blood volume and potential circulatory problems. Interventions range from simple things like adding salt to the diet and maintaining adequate hydration to medications such as beta receptor blocking agents.

Research into POTS is ongoing. A study published recently in the journal Neurology Today found POTS patients had high numbers of certain antibodies, pointing to a possible autoimmune connection. The website clinicaltrials.gov currently lists 64 studies into POTS, 12 of which are either actively or soon to be recruiting participants. POTS support groups, which connect patients and caregivers with others in their own area who are dealing with similar challenges, are listed at dysautonomiainternational.org. There's also an active POTS Facebook group with more than 6,000 members from throughout the world.

We wish we had more definitive answers for you and your daughter and hope that these resources will be of use.

Family History of Breast Cancer May Increase Males' Risk

Ask the Doctors by by Eve Glazier, M.D. and Elizabeth Ko, M.D

Dear Doctor: My husband's mother had breast cancer, and so did both of his aunts. He's really worried about our two daughters' risk, but I've read that breast cancer can affect men as well. Shouldn't he also be worried about himself?

Dear Reader: Most breast cancer is diagnosed in women, but you're correct -- it occurs in men as well. One percent of all breast cancers are found in men. For men who inherited the BRCA1 or BRCA2 genes, the incidence of breast cancer rises to 6 percent. (The BR of BRCA comes from the word "breast," and the CA from the word "cancer.")

Both boys and girls have a small amount of breast tissue around and beneath the nipple. When girls reach puberty, their bodies make hormones that cause the growth and development of the glands and ducts that will make and carry milk, as well as the surrounding tissues to support those structures. Men have significantly lower levels of these so-called female hormones, so their breasts don't develop in the same way. However, men still have that slight amount of breast tissue. And though the small number of glands and ducts found in male breast tissue are not functional, they can still be the site of breast cancer.

Male breast cancer can occur at any age but is more commonly found in older men. In addition to age, risk factors for men include a family history of breast cancer and the inherited gene mutations discussed above. Other risk factors include exposure to whole-chest radiation, as in certain cancer treatments, and liver disease. That's because one of the liver's many roles is the balancing of our sex hormones. In severe liver disease, hormone levels can become skewed and lead to an abundance of estrogen, which raises breast cancer risk.

As with all cancers, early detection is important. Since men have less breast tissue, lumps or other abnormalities can be easier to find. However, that same lack of tissue means there's less distance for cancer to travel and spread to surrounding tissues. Another factor is the lack of awareness that male breast cancer exists, which makes it easy to ignore warning signs. For men with a history of breast cancer in their families, as with your husband's, performing regular breast exams is a good idea. In addition to lumps, keep an eye out for changes to the skin or nipple, including redness, scaliness, dimpling or puckering, discharge from the nipple, and breast or nipple pain.

If anyone in your or your husband's family has the BRCA mutation, then your husband may want to consider genetic testing. If he does decide to follow through, we strongly recommend enlisting the help of a genetic counselor. At the very least, this family history of breast cancer should be information that your husband shares with your family doctor. When caught in the earliest stages, which accounts for close to half of all diagnoses, the five-year survival rate for male breast cancer is 100 percent. We can't think of a better reason to become vigilant.
