Is Parkinsons Disease Inherited
Scientists have discovered gene mutations that are associated with Parkinsons disease.
There is some belief that some cases of early-onset Parkinsons disease disease starting before age 50 may be inherited. Scientists identified a gene mutation in people with Parkinsons disease whose brains contain Lewy bodies, which are clumps of the protein alpha-synuclein. Scientists are trying to understand the function of this protein and its relationship to genetic mutations that are sometimes seen in Parkinsons disease and in people with a type of dementia called Lewy body dementia.
Several other gene mutations have been found to play a role in Parkinsons disease. Mutations in these genes cause abnormal cell functioning, which affects the nerve cells ability to release dopamine and causes nerve cell death. Researchers are still trying to discover what causes these genes to mutate in order to understand how gene mutations influence the development of Parkinsons disease.
Scientists think that about 10% to 15% of persons with Parkinsons disease may have a genetic mutation that predisposes them to development of the disease. There are also environmental factors involved that are not fully understood.
Common Symptoms Of Parkinsons Disease
Postural Instability: People with Parkinsons Disease have trouble standing up straight or maintaining their balance. A small push can send them tumbling. A stooped posture is common along with a slow, shuffling gait.
Change in Speech: Commonly people with Parkinsons Disease experience a change in the tone of their voice. It typically gets softer and becomes more monotone, McFarland says. You may not notice it yourself, but if your family members are saying, Speak up! or your friends ask you to repeat yourself, that may be an indicator that youre voices timbre has changed.
Change in Handwriting: Is your handwriting becoming small and illegible? You may be developing what is called micrographia. Dr. McFarland says that movements in general slow and become small, including handwriting. You may notice your handwriting trailing off the page, getting smaller and smaller, and harder to read.
A Shuffling Gait: If you have trouble walking, or your steps have become more of a shuffle than a walk, thats could be a symptom of Parkinsons Disease. Some patients experience what doctors call freezing. These are rigid spells where a person gets frozen in place, McFarland says. You turn or get to a threshold and get frozen in place, feeling like you cant possibly take another step. You need some cue, be it a sound, tactile, or visual , to get moving again.

Trouble Moving Or Walking
Do you feel stiff in your body, arms or legs? Have others noticed that your arms dont swing like they used to when you walk? Sometimes stiffness goes away as you move. If it does not, it can be a sign of Parkinson’s disease. An early sign might be stiffness or pain in your shoulder or hips. People sometimes say their feet seem stuck to the floor.What is normal?If you have injured your arm or shoulder, you may not be able to use it as well until it is healed, or another illness like arthritis might cause the same symptom.
Clinical Trials For Parkinsons
A number of clinical trials investigating the cause of Parkinsons, how the disease progresses, and new medications are also underway.
One ongoing study involves the use of a molecular medication that can cross the blood-brain barrier to target early Parkinsons to stop the progression of the disease to later stages.
Refer to the Parkinsons Foundation or ClinicalTrials.gov for information on additional clinical trials.
No home remedies can cure or reverse Parkinsons disease development or progress.
The following home remedies are being studied as possible promising therapies for Parkinsons disease:
- H2 water. H2 water is water with added hydrogen gas. Its being examined in experimental trials as a potential way to

How Are Parkinsons Tremors Treated
Tremor can be unpredictable. Some experts say itâs the toughest symptom to treat with medication. Your doctor may prescribe medication for your tremors:
- Levodopa/carbidopa combination medicines . This treatment is a type of medication called a dopamine agonist. Itâs usually the first treatment for Parkinsonâs.
- Propranolol . This drug is also used to treat high blood pressure, heart disease, and migraine.
- Clozapine . This medication is also used to treat schizophrenia. It requires weekly blood tests for the first 6 months.
Those taking levodopa/carbidopa may occasionally experience OFF periods in which their symptoms return. There are treatment options during these periods including a powder form of levopoda which can be inhaled or the medications istradefylline or safinamide .
When The Tremoroccurs Is Important
If shaking occurs during anaction reaching for something, writing, steadying a cup of coffee thatscalled an active tremor. Active tremors do not usually point to a seriousneurological disorder such as Parkinsons disease.
Even so, Dr. Gostkowski says its a good idea to talk to your doctor, who will look for underlying causes. For example, essential tremor, another much more common movement disorder, frequently occurs after age 50. Once the cause of an active tremor is identified, doctors can treat it.
If shaking occurs when the handsare at rest for example, folded in your lap thats called a restingtremor. If a resting tremor develops suddenly or worsens over time, itsimportant to see a doctor right away. Resting tremor may be a sign ofParkinsons disease.

Confusion With Essential Tremor
The tremor of Parkinsons disease is often confused with the tremor of a condition called Essential Tremor, or Benign Familial Tremor . Katherine Hepburn had Essential Tremor, and was originally misdiagnosed with Parkinsons. Ronald Reagan also had Essential Tremor. Both had a head tremor and a vocal tremor. In Essential Tremor, the hands are most commonly involved, followed by the head and then the voice. Essential Tremor can also cause the jaw to tremor, and it may be difficult to figure out if a jaw tremor is from Essential Tremor or Parkinsons. Unfortunately, some people may have both disorders. Some authorities believe that there is, in fact, an increased association between the two conditions, so that more people with Parkinsons disease have Essential Tremor than would be expected by chance alone, but this has not been established.
Essential Tremor Vs Parkinsons Disease
Essential tremor and Parkinsons disease are both adult-onset tremor disorders that can be characterized by shaking that affects daily life. If you have one of these conditions, you may find it difficult to hold onto items, struggle to write normally, and notice your hands shaking uncontrollably. However, beyond that, there are many key differences.
If you believe you may suffer from one of these conditions, this guide can help you better understand the signs that you may have Parkinsons disease or essential tremor, how each is diagnosed, and what the treatment process entails. If you have questions about a certain aspect of these conditions, use the links below to navigate to its specific section:

Cause Of Essential Tremor
Essential tremor is the most common type of tremor, and affects more people than Parkinsons disease. Some estimates suggest that around 1 in 5 people over the age of 65 years is affected.
There is no known cause, but a genetic link is strongly suspected. Each child of a person with essential tremor has a 50% chance of inheriting the disorder themselves. If a person with essential tremor has other affected family members, then the disorder is called familial tremor.
Symptoms Of Essential Tremor
The symptoms of essential tremor include:
- affects the voluntary muscles
- head nodding, if the head is affected
- shaky, quivering voice, if the larynx is affected
- a small, rapid tremor
- tremor that is exacerbated by activity or movement
- tremor that eases when the body part is at rest
- tremor that stops when the person is asleep
- worsening with age
- hands, head and voice are most commonly affected
- other body parts may become affected over time, including the arms and eyelids .

Tremor In Other Conditions
While tremor is a common symptom of PD, it can also be a symptom of other conditions, most notably essential tremor. The main difference between Parkinsons tremor and most other types of tremor is that in PD resting tremor is most common. Other conditions are usually characterized by action tremor, which tends to lessen at rest and increase when youre doing something, like trying to make a phone call or take a drink. Tremors of the head and voice are also common in essential tremor but rare in PD.
What Are The Symptoms
Symptoms of essential tremor vary from person to person, as does the rate of progression.
- Rhythmic tremors of the hands, legs, or trunk
- Head nodding in a “no-no” or “yes-yes” motion
- Voice quivering
- Tremors that occur involuntarily and cannot be stopped.
- Tremors that get worse during periods of stress and that lessen during rest.
- In rare cases, mild gait disturbance.

A trained, qualified healthcare provider should be the one to diagnose and treat essential tremor. Essential tremor isn’t life-threatening or dangerous, but tremors can also be a part of other conditions, some of which are treatable if caught quickly. Its important to call your healthcare provider and make an appointment if you start experiencing tremors that you cant explain.
Essential Tremor Versus Parkinsons Disease
Many people associate tremors with Parkinson’s disease, but ET and PDdiffer in key ways:
- Cause: ET has an unknown cause PD results from dopamine neuron destruction
- Timing of tremors: ET occurs when you use your hands PD tremors most prominent when hands are at sides or resting
- Associated conditions: ET doesn’t cause other health problems PD associated with stooped posture, slow movement, shuffling gait, and masses in the brain
- Parts of body affected: ET mainly involves head, hands, and voice PD usually starts in the hands but spreads to the rest of the body
If youre experiencing tremors, its always best to have a doctor check you out to make sure its nothing serious. Give the team at Memphis Neurology a call at either of our locations orschedule an appointment with us online today.

What Is A Parkinsons Tremor
Other health issues can also cause tremors, like multiple sclerosis or essential tremor. But Parkinsonâs tremors are different because theyâre usually:
- Resting. Parkinsonâs tremors happen when your muscles are still. They go away when you move. They also lessen while you sleep. For example, if youâre sitting in a chair with your arm relaxed, you may notice that your fingers twitch. But if youâre using your hand, like when you shake someone elseâs hand, the tremor eases or stops.
- Rhythmic. Parkinsonâs tremors are slow and continuous. They arenât random tics, jerks, or spasms.
- Asymmetric. They tend to start on one side of your body. But they can spread to both sides of the body.

Warning Signs Of Parkinsons Disease
Nine early warning signs of Parkinsons disease, according to Dr. Kilbane, are:
Its important not to jump to conclusions about your health or diagnosis if you or a loved one experiences some of these symptoms, but you should make your physician aware of them, Dr. Kilbane says.
What Treatments Are Available For Tremors
Of all Parkinsons disease symptoms, the effect of drug treatments on tremors are the most unpredictable.When starting Parkinsons medicine treatments, you and your family should not judge their effectiveness by decreased tremors, but the simplification of daily tasks.Some medication, such as anticholinergics and propranolol, can be specifically used to treat tremors. However, they are not recommended for the elderly.When tremors become too overwhelming, deep brain stimulation can be considered. This is the most effective and reliable treatment available for tremors.Some medications can make your tremors worse. Discuss this with your neurologist.

- Floors: Remove all loose wires, cords, and throw rugs. Minimize clutter. Make sure rugs are anchored and smooth. Keep furniture in its usual place.
- Bathroom: Install grab bars and non-skid tape in the tub or shower. Use non-skid bath mats on the floor or install wall-to-wall carpeting.
- Lighting: Make sure halls, stairways, and entrances are well-lit. Install a night light in your bathroom or hallway and staircase. Turn lights on if you get up in the middle of the night. Make sure lamps or light switches are within reach of the bed if you have to get up during the night.
- Kitchen: Install non-skid rubber mats near the sink and stove. Clean spills immediately.
- Stairs: Make sure treads, rails, and rugs are secure. Install a rail on both sides of the stairs. If stairs are a threat, it might be helpful to arrange most of your activities on the lower level to reduce the number of times you must climb the stairs.
- Entrances and doorways: Install metal handles on the walls adjacent to the doorknobs of all doors to make it more secure as you travel through the doorway.
Which Body Parts Do Parkinsons Tremors Affect
There are five main places youâll have Parkinsonâs tremors:
1. Hands. Parkinsonâs disease tremors often start in the fingers or hands with whatâs called a pill-rolling motion. Imagine holding a pill between your thumb and index finger and rolling it back and forth.
2. Foot. A Parkinsonâs foot tremor is more likely to happen while youâre sitting or lying down with your feet at rest. If the tremor moves into your thigh muscles. It could look like your whole leg is shaking.
Foot tremors disappear when you stand or walk because those are active movements. A foot or leg tremor while youâre standing may be another condition.
3. Jaw. This is common in people with Parkinsonâs. It may look like youâre shivering. It can become bothersome if the tremor makes your teeth chatter. If you wear dentures, it could make them shift or fall out.
Chewing eases the tremor, so gum might help.
4. Tongue. Itâs rare, but a tongue tremor can cause your entire head to shake.
5. Internal. Some people with Parkinsonâs say they can feel a shaking sensation in their chest or abdomen. But canât be seen from the outside.
