Handwriting Gives an Early Warning Sign of Parkinson’s Disease



January 20, 2014

Doctors usually diagnose Parkinson’s disease after patients complain of the telltale symptoms—tremors, rigidity, slowed movements, impaired balance. These signs typically don’t appear until this degenerative neurological disease is at a relatively late stage. In its early stages, however, Parkinson’s often goes unnoticed…which is a problem, because early diagnosis maximizes the treatment options.

Breakthrough: There’s a simple clue that can help detect Parkinson’s in the early stages, long before obvious symptoms appear, a new study reveals. All that’s required is putting pen to paper…

SMALL WRITING, BIG CLUES

The study included 20 patients who had been diagnosed with early-stage Parkinson’s disease and did not yet have obvious signs of motor impairment…plus 20 healthy people (the control group) who were matched for age, gender, education level and hand dominance. All of the participants were asked to write their names and copy an address. You may think that this is a very simple task, but actually it’s quite complex—because it involves manual dexterity as well as cognitive, sensory and perceptual-motor abilities.
For this study, the participants wrote on regular lined paper attached to an electronic tablet that could measure the amount of pressure applied. The writing utensil was a wireless, electronic pen with a pressure-sensitive tip. A computer assessed the pressure applied by the pen, the placement and angle of the pen’s tip, and the length of time it took to prepare and place the strokes of the pen. The length, height and width of the letters each person wrote also were measured.
Findings: Compared to the healthy control group, the patients with early-stage Parkinson’s…
  • Spent more time with their pens in the air between strokes (as if strategically planning their next move, the researchers said).
  • Applied less pressure when writing.
  • Required more time to complete the handwriting task.
  • Wrote smaller letters.
Simplest clue revealed: Next, the researchers determined that it was possible to identify, with 97.5% accuracy, which writing samples were produced by people with early-stage Parkinson’s based solely on the size of the letters! 
Researchers who were unaware of which writing samples came from which participant correctly identified 19 out of the 20 Parkinson’s patients as having the disease…and correctly identified all 20 of the healthy controls as not having the disease.
People with Parkinson’s frequently notice changes in their thinking ability before they notice any loss of motor skills. That’s why a handwriting test that also engages cognitive skills—as opposed to one that focuses strictly on motor skills, such as drawing spirals (an assessment test doctors often use)—could well help doctors diagnose the disease in its early stages.
This was a fairly small study, so the results will need to be replicated in larger studies before the handwriting test could become a standard diagnostic tool. But in the meantime, why not test yourself? Write your name and copy several addresses, then compare what you’ve written to a sample of your handwriting from years ago. If your letters have become noticeably smaller, bring this fact to your doctor’s attention, show him/her this article and ask whether you might benefit from being evaluated for Parkinson’s.

Stroke: It’s On the Rise Among Younger People

January 1, 2013



Unfortunately, only about 20% to 30% of them go to the ER…

3713.jpgFew people in their 40s or 50s can imagine having a stroke, particularly if they are generally healthy. But the risk is higher than you might think—dispelling the common belief that stroke is a risk for only the elderly.
An unexpected trend: Over the last several years, there has been an increase in strokes among adults in their 40s, 50s and 60s. What’s most alarming about this development is that doctors don’texpect to see strokes in these relatively young patients, so the diagnosis sometimes gets overlooked.
Important finding: One in seven young stroke patients was initially misdiagnosed as having another problem, such as a seizure or alcohol intoxication, researchers at Wayne State University–Detroit Medical Center found in a recent study.
What to do: First and foremost, be alert.Stroke can occur at any age, so it’s important for all adults to pay close attention to symptoms. If you are diagnosed and treated within about four hours of having a stroke, you are far more likely to recover than someone whose diagnosis and treatment are delayed. Unfortunately, only about 20% to 30% of young patients with stroke symptoms go to the emergency room, according to research. The others are likely to shrug off the symptoms (especially if they were relatively minor and/or short-lived) and do not learn that they have suffered a stroke until a subsequent problem is detected later on.

WHAT’S CAUSING EARLIER STROKES?

Many of the so-called “age-related” diseases that greatly increase stroke risk, such as high blood pressure (hypertension), diabetes and high cholesterol, are now appearing in patients who are middle-aged or younger—primarily because so many Americans are eating more junk food, gaining too much weight and not getting enough exercise. Family history is also a risk factor for stroke.
But even if you don’t have any of these conditions (or a family history of stroke), you are in good physical shape and generally eat a well-balanced diet, do not be lulled into a false sense of security. Anyone can suffer a stroke. That’s why it’s very important for all adults to be on the lookout for red flags that could signal a stroke.

PREVENTION WORKS

Stroke is the fourth-leading cause of death in the US. Those who survive a stroke often face a lifetime of disability, including paralysis and speech and emotional difficulties.
Fortunately, younger patients, in general, are more likely to recover than older ones because their brains have greater plasticity, the ability to regain functions after stroke-related trauma. Even so, many young stroke patients will have permanent damage.
Important: Regardless of your age, fast treatment is critical if you experience stroke symptoms. The majority of strokes are ischemic, caused by blood clots that impair circulation to the brain. Patients who are given clot-dissolving drugs, such as tissue plasminogen activator (tPA), within the first few hours after a stroke are far more likely to make a full recovery than those who are treated later.
Up to 80% of strokes can be avoided by preventing or treating the main risk factors, according to the National Stroke Association. For example, not smoking is crucial—people who smoke are twice as likely to have an ischemic stroke as nonsmokers.
Also important…
Do not ignore hypertension. Like stroke, hypertension is often viewed as a problem only for the elderly. But there’s been an increase in hypertension in younger patients, who often go undiagnosed.
Warning: Uncontrolled high blood pressure damages the brain—even in patients who haven’t had a stroke, according to a new study published in The Lancet Neurology.
If your blood pressure is high (normal is below 120/80), you are two to four times more likely to have a stroke than someone with normal blood pressure.
What to do: All adults should always have their blood pressure taken during routine doctor visits (at least once every two years if your blood pressure is normal…and at least annually if you’ve been diagnosed with hypertension or prehypertension). You can reduce both blood pressure and the risk for stroke by maintaining a healthy body weight…eating a healthful diet…getting regular exercise…and taking medication if your blood pressure remains elevated despite lifestyle changes.
Manage diabetes. It’s second only to hypertension as a risk factor for stroke. Diabetes increases the risk for all cardiovascular diseases, including hypertension. People who have diabetes are up to four times more likely to have a stroke than those without the condition.
What to do: Get tested. The American Diabetes Association recommends that all adults age 45 and older get screened for diabetes every three years.
If you already have diabetes, do everything you can to keep your blood sugar stable—for example, eat properly, get exercise and lose weight, if necessary.
Keep an eye on your cholesterol. It’s the third most important stroke risk factor because LDL (“bad”) cholesterol can accumulate in the arteries, impede circulation to the brain and increase the risk for blood clots.
What to do: Beginning at age 20, get your cholesterol tested at least every five years. If your LDL is high (less than 100 mg/dL is optimal), you’ll want to get the number down by eating less saturated fat…getting more vegetables and other high-fiber foods…and possibly taking a statin medication, such as simvastatin (Zocor). Depending on the drug and dose, statins typically lower cholesterol by about 25% to 50%.
Pay attention to your alcohol consumption. People who drink heavily (three or more alcoholic beverages daily for men and two or more for women) are more likely to have a stroke earlier in life than moderate drinkers or nondrinkers.
In fact, in a study of 540 stroke patients, French researchers found that heavy drinkers suffered their strokes at age 60, on average—14 years earlier than patients who drank less or not at all.
Warning: Heavy use of alcohol is also associated with increased risk for hemorrhagic stroke, which is caused by bleeding in the brain (rather than a blood clot). This type of stroke can occur even in patients without a history of serious health problems.
What to do: If you drink, be sure to follow the standard advice for alcohol consumption—no more than two drinks daily for men…or one for women.

SURPRISING RED FLAGS FOR STROKE

Stroke symptoms aren’t always dramatic. If you’ve had a minor stroke or a transient ischemic attack (a brief interruption of blood flow known as a “ministroke”), the symptoms might be fleeting and easy to miss.
What’s more, in rare cases, symptoms may occur that you may not think of in relation to a stroke. For example, you may initially feel disoriented or experience nausea, general weakness, face or limb pain, chest pain or palpitations—all of which typically come on suddenly. Depending on the part of the brain that’s affected, you may not be aware of your symptoms and must rely on someone else to call for help.
Don’t take chances. Get to an emergency room if you have these and/or the classic symptoms below—FAST (Face, Arm, Speech and Time) is a helpful guide.
Face: The most common stroke symptom is weakness on one side of the body, including on one side of the face. You may have difficulty smiling normally.
Arm: One-sided weakness often affects one of the arms. Hold both arms out to your sides. You could be having a stroke if one of your arms drops down.
Speech: Your words could sound slurred, or you might be unable to say a simple sentence correctly.
Time: In the past, the “window” to receive clot-dissolving medication was considered to be three hours. New research indicates that stroke patients can benefit if they get treated within 4.5 hours after having the first symptom.

5 Questions Doctors Should Ask



January 1, 2014


4506.jpgWhen you see a doctor for the first time or visit your longtime doctor just for a routine checkup, if you're like most people, you probably spend no more than a few minutes talking about yourself or your problem. Chances are, a naturopathic physician—or any doctor who has a holistic (whole-body) approach to practicing medicine—would never settle for that.* 
Below are five key questions that I routinely ask my new patients. If you see a new doctor who doesn't ask these types of questions or your own doctor has never inquired about such information, give as much of it as possible to him/her anyway. Your answers may well affect your diagnosis and treatment. If the doctor isn't interested in hearing these details, consider replacing him with a doctor who is. 

Questions all doctors should ask…

Question #1: What's your health time line? On my intake form for new patients, I ask for a health history that includes significant events they believe may have affected their health—both emotional events (such as marriage, divorce or loss of a loved one) and medical events (surgeries, accidents or major illnesses) may be listed by the patient. Besides giving me information I can use as a physician, filling out this form arms patients with self-awareness, so they become better prepared to ask questions and give more pertinent details during our appointments.
Question #2: How are your diet and digestion? To help assess digestive function and nutrient status, I ask about patients' eating habits and how well they feel they digest their food. It's also useful to learn what foods they crave, what foods they dislike and what they ate in childhood. Additionally, I want to know whether they have daily bowel movements or any pain with digestion and elimination. I've found that many patients don't really know how to eat a balanced diet, and helping them correct that (with specific dietary goals) can lead to huge strides in overall health.
Question #3: What's your daily fluid intake? Sometimes, a seemingly mysterious medical problem is simply due to a person getting too much caffeine, alcohol and/or soda (regular or diet). And some people drink zero ounces of plain water daily. These individuals often are surprised to hear (but later thankful when they start to feel better) that I recommend drinking half of one's body weight in ounces of water daily! Low water intake can be hard on the kidneys and heart, in particular.
Question #4: How is your sleep? This includes total hours of sleep time, when they go to bed, when they get up and sleep interruptions. I also want to know where a person sleeps. Surprisingly, many people spend the night in a recliner or in a child's bedroom. Knowing a person's sleep patterns can offer significant clues that help diagnose and treat ailments.
Question #5: How's your emotional health? Are you happy, restless, angry, resentful, peaceful, longing for change or generally content? This information gives me a better understanding of how best to treat the person I am caring for—emotional issues can worsen or cause physical symptoms.
