Internal Tremors----felt by the patient but not seen by others

Fifty years of age, with a multitude of health problems, he appears at the clinic to rule out parkinsonism as the cause of his tremor. Since he began using the CPAP machine to sleep, he has noticed feeling tremulous in the morning. Sometimes the symptom lasts only an hour, but occasionally the feeling stretches out to encompass the entire day. The movement disorder specialist asks what part of the body is affected. With his hand to his chest, the patient indicates he feels the vibrations occurring in his torso, and the movements feel similar to the heart palpitations he's experienced, though he has asked his wife to touch his shoulder and see whether she can detect the quivering motion, and she feels nothing.

The doctor considers this then gazes at the patient's medical history. Various practitioners have diagnosed the patient with lupus, myasthenia gravis, and multiple sclerosis- all neurological conditions. The doctor states that lupus can produce a wide range of neurological conditions, and possibly tremor. Diabetics may also experience tremor in an episode of low blood sugar or hypoglycemia, occurring due to an imbalance between insulin or diabetic medication, food consumption and level of exercise and activity. The patient is unable to exercise due to failed spinal surgery. He recounts he has put on eighty pounds because of his immobility. Diabetes as a cause of the trembling doesn't seem to fit the patient's description of the action continuing throughout the day.

The specialist relates in a study he is familiar with, people with Parkinson's disease were asked whether they experienced an internal tremor. Those that reported such a sensation all had depression in common. For people diagnosed with PD, there appears to be a correlation of that symptom and clinical depression. Though the patient lacks slowness, rigidity, and a resting tremor, a course of an antidepressant may alleviate his symptom. The medication the physician has in mind is an old-fashioned antidepressant, Doxepine. However, the medication can't be given to people with cardiac arrhythmias, which he experiences. Inderal or the generic propanalol is helpful in blocking tremor, though the medication also veils the symptoms that come as a consequence of hypoglycemia; dangerous for a diabetic who may pass out or experience a seizure when blood sugars drop too fast.

Depending upon how uncomfortable the tremor is, the physician concedes the whole class of SSRI's that include Zoloft, Paxil and Prozac are possibilities, if he would like to see whether they calm the symptom. The physician concedes the good news is the patient does not have evidence to suggest he suffers from parkinsonism.

Second Opinion

The dark glasses he wears lie on the physician's desk in front of him; he had cataracts removed from both eyes, but he still suffers from macular degeneration- a condition where retina gradually thins and results in blindness. He carries a large magnificying glass which he holds close to his nose as he peers at his list of medications. The purpose of the visit is to seek another opinion regarding the tentative diagnosis of Parkinsonism. He has already seen several physicians who have conflicting opinions about his tremor.


Losing his hearing, the patient asks the doctor to speak up, interrupting him, as he speaks. The doctor repeats himself, with abbreviated thoughts. The patient holds his palm up towards the doctor, interrupting, telling him to let him speak. His hands are big, his finger long. Several of the fingernails on his left hand are cropped off, midway through the nail. He is 88 years old and states with a serious expression that he expects to live to 120. An American chess champion in the over 75-year division, he visits Florida once a year to compete. He claims in his youth he could play ten games blindfolded, now he can play only one game this way; his short term memory is not what it was. But it is the tremor in his hands that bothers him, especially when eating soup. Three years ago, he noticed his handwriting became larger and shakier. He comments also he has lost the bounce in his step; he no longer rises up onto his forefoot when he walks. Balancing is tricky.



The doctor stands and takes the man's hand, and folds it inward towards his shoulder and out. He tells the patient his upper body is supple, without rigidity. The patient concedes he was a magician, and takes a packet of cards from a small leather case in his trouser pocket. He describes a trick he was able to do with one hand, holding the deck of cards divided into two bundles, he was able to shuffle them with one hand. Standing, he positions the cards in his left hand, and then nothing happens. The doctor follows his actions, and nods, understanding dexterity is gone from his hands. With a tuning fork, the doctor assesses the patient's reflexes and notes whether the patient can sense the vibration of the fork, when applied to the bony prominences of his feet and legs. Noteworthy, the patient fails to feel vibration applied to the right leg. The physician explains it is a cheap way of assessing the integrity of the long nerves in the body, and states the lack of sensation explains some of the change in his walking style, as he appears to have a mild sensory neuropathy. The cause, the physician guesses is from compression of the nerve roots in the spine. The doctor explains we rely on three mechanisms to keep us upright in space; position sense derived from the sensory nerves in our limbs that pick up vibration, fine touch and temperature; our vestibular system and our vision.



When the physician summarizes his findings, he notes the patient has a mild action tremor, and a mild sensory abnormality in the right leg and foot. He would like an MRI to look at the blood vessels of the brain. However, the patient leaves on Thursday to his home state, he'd prefer to have the testing performed there. The doctor agrees to send notes to the physicians involved in his care and the conversation shifts to what sort of cutting edge therapies exist in the field of Parkinson's and Alzheimer's disease. Sitting behind the desk, the physician explains a study in which people with Alzheimer's are getting GCSF(granulocyte- colony stimulating factor) to remove the amyloid plaques from the brain and improve cognition. The patient voices some interest in undergoing the same treatment, and the doctor wonders whether that would be ethical, or even practical, as the patient lacks the symptoms of those with the illness. He also notes when the amyloid is removed it can get stuck in small blood vessels, and result in micro-hemorrhages. He is unsure of the consequences of such trauma in the brain of a healthy, yet older individual. The man, wearing a woolen red sweater over a collared shirt, reaches into a file and withdraws the list of therapies he receives regularly from a physician whose specialty is aging. In the second or third line is a product called Neupogen, the same substance used in the research study for patients with Alzheimer's.

Sickness

A patient reported today the Neupro patches they requested from a Spanish pharmacy were returned because the dry ice required for shipping required special consent and paperwork. The patient continues to try and balance his medications, attempting to find a happy equilibrium between over medication and dyskinesia, and under medication resulting in more slowness, rigidity and episodes of freezing. The specialist in movement disorders commented freezing episodes usually occur independent of medication dosages. However, the patient claims Sinemet relieves such episodes. To manage the balancing act, the physician recommended cutting back on the Requip; he prescribed 1 mg tablets, to replace the 2 mg dose.

The patient had been interested in deep brain stimulation for controlling dyskinesia, and had visited a specialist in another city for a consultation. The clinical physician commented, of the six patients he has that have undergone surgery, only two continue to do well with their implants. He emphasized the surgery doesn't cure anything, and the operation comes with considerable risks; settings require adjusting and not all clinical staff are capable of superior post- operative care. While training is required to adjust settings, a spectrum of talent is employed to maximize the beneficial effects of neurostimulation.

The patient scheduled for 2:00pm sat in the waiting room for an hour and a half before the staff realized the allotted patient appointment drifted past. Consequently, the patient was in an ugly frame of mind. Though the reason for the visit was called, "Tremors" the patient exhibited none of the characteristic motions. Instead, the patient described spontaneous, involuntary movements like sudden face slaps, jerks, or kicks. The physician inspecting the patient's medical record noted the patient took a wide variety of antidepressants, and pain pills. Several of the daily medications are capable of producing involuntary movements and slurred speech. While the patient waited two months for an examination by the movement disorder specialist, hoping that the doctor would be able to identify the ailment and how to fix it. The patient's hopes crushed, tears flowed. The specialist stated he was the wrong doctor to be handling the case
and in his opinion the medications were the cause of the involuntary movements.

The specialist recommended the patient phone the social worker and begin the process of applying for disability. Clearly, it would be hard to keep a telephone position with a slurred voice, and inability to write in a timely manner. The good news was the patient suffered from no neurological degenerative sickness; the bad news was the patient was too depressed to appreciate good physical health.

Lewy Body Disease?

The son and daughter of the patient bring her to the movement disorder specialist with a provisional diagnosis of Lewy Body Disease. Frederic Lewy gave his name to the bits of protein he found in the cytoplasm of cells throughout the brain in the early 1900s. The illness is characterized by dementia, fluctuations in cognition- attention, alertness and thinking ability from day to day, and Parkinsonism.

Lewy Body Disease might have made a more simple patient case. The actual patient had a history of high blood pressure, neurosurgery to correct a potentially fatal aneurysm, which Wikipedia defines as a "blood-filled dilation (balloon-like bulge) of a blood vessel caused by disease or weakening of the vessel wall." Neuroradiology discovered a tumor on her cerebellum while performing an MRI to ascertain the state of the aneurysm. The children of the patient noted she had trouble finding the appropriate words for objects, following surgery, an observation that coincides with an aneurysm on the left side of the brain, the language center. After surgery, patients routinely receive Dilantin, prophylactically, to avoid seizures caused by minute scarring of cortical tissue. The patient never took the medication and suffered a seizure in the presence of her 85-year-old husband. The children also reported an incident in which the patient, "went crazy" after her medications were changed. Though the craziness subsided with new drugs, she still suffered from significant mental changes, for example she could not report her correct age.

With all her troubles, the children of the patient commented she was in good health and rarely needs medical attention. On physical examination, the specialist noted tremor in her left hand and arm with less involvement on the right side. He felt some rigidity, more on the left than right, when the patient was distracted by performing a concurrent activity- in this case; she tapped her palm on her thigh. Parkinsonism also appeared as decreasing amplitude in repeated finger to thumb tapping. Of note also were brisk reflexes and upward going toes- a Babinski sign indicative of brain disease, specifically damage to the corticospinal tracts. The patient felt incapable of independent walking, so the physician gauged her standing and balance skills. Without support, she could stand with feet touching, though the left side of her body twitched noticeably. With her eyes closed, she stood considerably less still and when jostled she lost balance quickly.

The patient complained most about the tremor on the left side of her body. This symptom is what the specialist addressed, by recommending a medication that successfully quells tremor that would not interact with her other medications. To complicate matters a bit more, the doctor learned the patient refuses to take any medications given to her by her husband, with whom she lives. The patient fears he is trying to kill her. For this reason, an independent person must visit the home bringing the necessary drugs.

When the dilemma unfolded, the physician commented Medicare pays for home health to dispense medications. He wrote a prescription for this service, as well as for physical therapy. The patient left the office on the arm of her son, and was clearly unstable with tremor rocking the left side of her torso.

Hints of PD

She just wanted to be told she didn't have Parkinson's disease. Unfortunately, the doctor couldn't dispel her worries. She did have tremor; what sort of tremor is questionable. Sometimes causes are unclear, time helps clarify issues, though few people can ever pinpoint the cause of Parkinson's disease. Those who can identify a true cause of the illness may subscribe it to having a genetic mutation, though familial patterns of Parkinson's disease are quite rare.

The patient suffered from temporal arteritis, inflammation of the temporal artery. The harrowing condition has symptoms like tenderness of the scalp and hair, pain in the jaw and when chewing, and loss or blurriness of vision. Doctors prescribe oral steroids to bring inflammation under control, because vision can be lost and never regained if flow through the ophthalmic artery gets disrupted and the patient has no secondary means of blood circulation to the eye. For some reason, women are three times more likely to suffer from this problem than men. Rheumatoid arthritis or systemic lupus erythematosus may coincide with the ailment; the patient lived with the former.

Upon examination, the doctor noticed brisker reflexes on the right side as well as slight rigidity when engaged in a simultaneous task. Though the patient reported a tremor that could shake wine from her glass, the tremor during examination was mild and fine. Might arteritis be the cause of her physical symptoms? Rigidity may result from inflammation in the brain, but the spouse reported tremor was worsening. With the course of steroids, inflammation should resolve, causing rigidity to improve.

Worsening tremor is unlikely to result from inflammatory processes in the brain. If the patient suffers from a Parkinsonian syndrome then tremor should gradually worsen and involve both sides of the body at rest, or other symptoms should appear. With the request to return to clinic in six months to a year, the physician prescribed Selegiline with the hope of forestalling and diminishing a possible loss of dopaminergic neurons.

Dad- a Clinic Day without PD Patients

My father used to be 5'10", now he's 5'6" or so. With my high heels on, I am as tall as he is. He's got that hunched over Parkinsonian posture. I tried to fix it by putting my shin near his spine and pulling his shoulders back. He shouted at me. I couldn't get him to extend his chest at all, his shoulders and pectorals have very little 'give'.

At home, he has a regular exercise routine, but the day I saw him he and his generation opted to eat dinner in the hotel restaurant, rather than walk the block and a half to the grill and microbrewery. When we did walk together, I took his arm, hoping that a little support would encourage a more spirited pace. Usually it failed, but at least he could hear me. He stops when he talks. I acquired the habit of either not talking, or monopolizing all the words, so we could continue moving.

Apathy comes. He is content to read the paper all day, drinking black coffee. I hear he does little housework and does not help with chores. When these things are pointed out, he shrugs his shoulders. My Dad has always favored well-cooked meat. At the hotel restaurant, he requested well- done bacon; it looked like jerky, he was delighted. He ate his bacon with dry toast- also well- done. I informed him the protein in the meat would affect how well his medications worked. He has never been science - oriented, he is an English and History teacher. I told him about neurotransmitters and how dopamine and proteins compete for the same sites, but I don't think he knew what I was saying, except that I thought the bacon was a bad choice.

Ages ago, I found a map of Wyoming or North Dakota with a town bearing our family surname. I showed it to him at the hotel breakfast.

"Yeah, I knew about that." He wasn't impressed.

On certain nights of the week when his wife works late, he cooks dinner. It can be a contentious event, apparently. Dad would not disclose what was for dinner on a recent night; he'd already had one argument about it. He likes meat and potatoes and tolerates a vegetable. How do the bowels of this man work? He lives primarily on bread and meat, and drinks no water, just black coffee during the day.

I am the delinquent one, the daughter who has never visited him, and he is nearing 78. At the end of our visit, I hug him and tell him I love him. He may have become apathetic, but he is teary to see his three daughters leave.

Hope is Hard to Kill

The patient hoped there was something in her a neurosurgeon could fix, to alleviate the tremor of her left hand. Unfortunately, she lived with several poorly aligned vertebrae in the cervical area and the doctor could see no reason on the MRI for a tremor. He wasn't the first physician to tell her this. Two neurosurgeons and a neurologist confided they saw no cause for tremor on the images of her brain and upper spinal column. Still hope is hard to kill. Clinically, the tremor she endured would be classified as mild, yet because it was her arm and hand, she conceived the movement as pronounced and problematic.
An older woman- she thought herself so, her birthday three years before the physician behind the desk, she suspected her tremor might be part of aging. The doctor assured her she was not old, and tremor is not a natural consequence of increasing age. He pointed with both hands to his head of dark hair shot through liberally with graying streaks, encouraging her to change her thinking on that matter.
With a Latin surname, a Florida speech pattern and the pale eyes and skin, I assumed she was a descendant of an original Florida family, but I was wrong. She still used the name of her former husband. Her manner so mild, I feared she would cry, outnumbered in the examination room by the clinical coordinator, the physician and myself.
The specialist recommended amantadine for the tremor, two pills a day- one at breakfast another at dinner or before bed. The drug has other properties as well as reducing tremor; it is anti- viral, so patients experience less flu and colds while taking it. While Azilect might stabilize symptoms, it is also an MAO inhibitor and possibly problematic, as one must avoid certain foods- aged meats, cheeses, and certain other drugs. He also strongly advised an antidepressant to lighten the cloud she carries over her head.
The MRI mages produced an unusual finding, a calcified meningioma: a very slow- growing tumor of tissue involving the tissue of the meninges. The doctor fished into the large envelope searching for a report to see what the radiologist concluded, and confirmed his own diagnosis. Women apparently have a greater quantity of such tumors.
Small, round, light splotches speckled the brain on the MRI. The doctor gave this a medical term, "leukoareosis". Apparently, leaky blood vessels in the brain show up on MRIs due to their excess fluid, a natural consequence of high blood pressure. They also, cannot be blamed for instigating the tremor of the left hand.
