What Are The Symptoms Of Atypical Parkinsonian Disorders

Doctors: Misdiagnosed Brain Disorder Mimics Parkinson’s

Like classic Parkinsons disease, atypical Parkinsonian disorders cause muscle stiffness, tremor, and problems with walking/balance and fine motor coordination.

Patients with atypical Parkinsonism often have some degree of difficulty speaking or swallowing, and drooling can be a problem. Psychiatric disturbances such as agitation, anxiety or depression may also be part of the clinical picture.

Dementia with Lewy bodies can cause changes in attention or alertness over hours or days, often with long periods of sleep during the day. Visual hallucinations typically of small animals or children, or moving shadows in the periphery of the visual field are common in DLB. DLB is second only to Alzheimers disease as a cause of dementia in the elderly, and it most commonly affects patients in their 60s.

Patients with progressive supranuclear palsy may have difficulties with eye movements, particularly when looking downward, and with balance when descending stairs, for instance. Backward falls are common and may occur during the early course of the disease. PSP is not usually associated with tremor, unlike Parkinsons disease.

Parkinsons Disease and Movement Disorders Center

Multidisciplinary Movement Disorders Clinic

Patients who come to the Movement Disorders Clinic are seen by a movement disorders specialist, a neurologist who has extra training in evaluating and treating a person with Parkinsons disease. There are no blood or imaging tests that can confirm Parkinsons disease, so diagnosis is based on visible signs and symptoms, which are reviewed during a medical history and neurologic examination.

Whats The Difference Between Multiple System Atrophy And Parkinsons

Parkinsons and MSA both affect the movement control system and the involuntary autonomic control system and early symptoms can make a differential diagnosis a challenge. MSA, however, tends to progress faster than Parkinsons balance problems and a stooped posture happen earlier and get worse more quickly with MSA and autonomic functions such as blood pressure, heart rate, breathing, sweating, bladder function, and sexual problems are more severe in people with MSA.

Other Types Of Parkinsonism

Like Parkinsons, MSA can cause stiffness and slowness of movement in the early stages. However, people with MSA can also develop symptoms that are unusual in early Parkinsons, such as unsteadiness, falls, bladder problems and dizziness.

PSP affects eye movement, balance, mobility, speech and swallowing. Its sometimes called Steele-Richardson-Olszewski syndrome.

Normal pressure hydrocephalus mainly affects the lower half of the body. The common symptoms are walking difficulties, urinary incontinence and memory problems. Removing some cerebrospinal fluid through a needle in the lower back can help with these symptoms in the short term. If there is improvement after this procedure, an operation to divert the spinal fluid permanently can help in the long term.

While these are not parkinsonian disorders, you may be diagnosed with one of these conditions if tremor is your only symptom.

There are several other, much rarer, possible causes of parkinsonism. These include rare conditions like Wilsons disease, an inherited disorder where theres too much copper in your bodys skin and muscles.

Case illustration

A 54-year old female developed dragging of her left leg and frequent falls. She also complained of urinary frequency and urgency that progressed to incontinence. She was initially diagnosed as having Parkinsons disease. She then developed double vision on looking up and down at age 58, and a vertical supranuclear gaze palsy and apraxia of eyelid opening was observed at age 60. The clinical diagnosis was revised to PSP. Throughout the course of her illness, she was reported as having antecollis, contractures of her feet and a jerky myoclonic postural and action tremor of the hands. Emotional lability and pathological laughter were also prominent features in her last 3 years of life. She died 9 years after onset of her first symptoms. At autopsy, a pathological diagnosis of MSA was made. Tau immunohistochemistry showed moderate numbers of neurofibrillary tangles and neuropil threads in the transentorhinal cortex . There was no amyloid- pathology in the brain. Key clinical features of all PSP mimics are described in Supplementary Table 2.

Imaging Biomarkers In Parkinsonism

DaTscan: dopamine-active transporter scans showing binding of 123I-fluoropropyl to DaT protein in the nigrostriatal nerve endings of the striatum. Normal: symmetrical normal specific binding of FPCIT in striatum. Parkinson’s disease: reduced specific binding of FPCIT in the posterior striatum, particularly on the left .

Further imaging approaches are in development on a research basis. 7-T MR scanning can detect structural nigral abnormalities. Diffusion-tensor MRI and diffusion-weighted imaging have shown some promise in diagnosing PD and its mimics. Transcranial sonography can detect hyperechogenicity in the midbrain of patients with PD. Although this is not specific, it may be a marker of susceptibility to PD.,,

Other Illnesses Mimic Parkinsons

DEAR DR. DONOHUE: My brother-in-law and a close neighbor are both in their mid-70s. Both shuffle their feet when they walk and have a slight shaking of their arms and other symptoms regarded as Parkinsons disease.

A short time ago, there was a segment on TV about these same symptoms, with an elderly man crossing the stage, stooped over, shaking and shuffling his feet. The announcer said he did not have Parkinsons disease. The sickness was three initials. Everyone remembers the program, but no one remembers what those three initials are. Can you help me?


ANSWER: The three major Parkinsons signs are bradykinesia a Greek word whose literal translation is slow movement resting tremor and muscle rigidity. People with bradykinesia take a long time to start any movement and a long time to execute the movement. For instance, they take forever to get out of a chair, and they chew slowly. When they walk, they take short steps and barely swing their arms. The Parkinsons disease tremor is a resting tremor. That means it comes on when the hands are idle, resting in the lap. Muscle rigidity is resistance to bending an arm when another person tries to bend it.

As the illness progresses, Parkinsons patients often walk stooped over, with both knees bent, and take baby steps on their toes. Their gait may speed up uncontrollably as they walk. Theyre prone to falling.

What Diseases Can Be Mistaken For Parkinsons

This is the list of different diseases that may be mistaken with Parkinsons disease:

  • Progressive supranuclear palsy.

Alzheimers disease and primary lateral sclerosis can also be mistaken for Parkinsons disease. Other similar conditions include essential tremor, dystonic tremor, vascular Parkinsonism, and drug-induced Parkinsonism.

Also Know, what are the four cardinal signs of Parkinsons disease? Cardinal symptoms. Four symptoms are considered cardinal in PD: bradykinesia, tremor, rigidity, and postural instability also referred to as parkinsonism. Tremor is the most apparent and well-known symptom.

Similarly, it is asked, what is similar to Parkinsons?

Progressive Supranuclear Palsy: An Atypical Parkinsonian Syndrome. Progressive supranuclear palsy is not Parkinsons disease , but is a Parkinsonian-like syndrome. PSP is a rare brain disorder that causes serious and progressive problems with gait and balance, as well as eye movement and thinking problems.

Does stress cause Parkinsons disease?

Research suggests that stressful life events may increase the risk of Parkinsons disease. In addition, animal studies indicate that stress damages dopamine cells, resulting in more severe parkinsonian symptoms. In humans, acute stress can worsen motor symptoms, including bradykinesia, freezing, and tremor.

Does Parkinsons Affect Voice

Robin Williams had a disease that mimics Alzheimer’s, Parkinson’s and schizophrenia

The voice is affected too, because the voice box is ultimately controlled by the basal ganglia as well. Thus the voice becomes soft, slurred and hushed. Others may comment that the patient is mumbling. The mumbling goes away temporarily once the patient becomes aware of it but soon returns to the soft, slurred state.

This temporary improvement when attention is paid is true of many of the motor symptoms of PD because the condition primarily affects subconscious movements, and does not directly affect nerve or muscle control at the most basic level. Thus, conscious awareness can override the slowness to a certain extent. This fact is one reason why physical therapy and physical activity are so useful and necessary in treating PD.

  • Slowness of walking and other movements
  • Trouble with dexterity
  • Reduced arm swing or stride length
  • Delayed reactions physically
  • Reduced facial reactions
  • Softer or slurred speech
  • Tremor in one or both limbs with the limb at rest
  • Sometimes also tremor with holding a posture or with actions
  • Usually asymmetric

Imbalance, loss of balance reflexes

  • May fall backwards

The Diagnosis Of Idiopathic Parkinsons Disease

The first component to the diagnosis of PD is establishing that the patient has parkinsonism. This is a clinical diagnosis and relies on three key elements: bradykinesia, tremor, and rigidity. Of these, bradykinesia must be present, with at least one of the other two. PD is an asymmetrical condition, so during the clinical assessment, the parkinsonism should be more apparent on one side and may be purely unilateral in early disease . is a classical illustration of parkinsonism, with a description by William Gowers.

Whats The Difference Between Corticobasal Degeneration And Parkinsons

The main difference between CBD and Parkinsons is that it usually starts on one side with the gradual loss of use of one hand or leg , and there may be little flicks of involuntary muscle jerks. Walking and balance difficulties usually occur later in CBD than in Parkinsons. Also, in CBD, a person may have trouble with purposeful movements, such as buttoning a shirt or cutting food.

Parkinson’s Disease Is Often Misdiagnosed In People With Paraquat Exposure

Posted on 2nd March, 2021

by Legal Staff

Because the symptoms of Parkinson’s disease are very similar to those of other health problems, it is often misdiagnosed in people with a history of exposure to paraquat, which prevents victims of toxic exposure from recovering the financial compensation they deserve. According to medical studies, Parkinson’s disease is misdiagnosed in up to 30% of cases and the rate of misdiagnosis is even higher in people whose disease is in the early stages. 1 in 4 people with Parkinson’s disease will receive a wrong diagnosis

Therefore, seeking a second and even a third opinion is essential in being assigned a correct and accurate diagnosis. It is a known fact that frequent exposure to paraquat in agricultural workers increases the risk of developing Parkinson’s disease by 250%.

Thereby, if you have a history of paraquat exposure, it is crucial to keep a close eye on your health for the symptoms of Parkinson’s disease.

A poll from the American Journal of Managed Care found that over 26% of people with Parkinson’s disease were initially misdiagnosed and 21% had to see their general healthcare provider 3 times before being referred to a specialist to have their health problem correctly diagnosed.

Women with Parkinson’s disease seem to be more frequently misdiagnosed than men. Because the disease usually occurs in people over the age of 40, the early onset of it may be misdiagnosed as a more common health problem for this demographic.

How Is A Diagnosis Made

Widespread transneuronal propagation of

Because other conditions and medications mimic the symptoms of PD, getting an accurate diagnosis from a physician is important. No single test can confirm a diagnosis of PD, because the symptoms vary from person to person. A thorough history and physical exam should be enough for a diagnosis to be made. Other conditions that have Parkinsons-like symptoms include Parkinsons plus, essential tremor, progressive supranuclear palsy, multi-system atrophy, dystonia, and normal pressure hydrocephalus.

In general, Parkinsons-like symptoms should improve after the medication causing the problem is stopped. Unfortunately, its not a quick fix it could take months.

In some cases, the drug-induced symptoms might actually reveal a previously unknown chronic condition like actual Parkinsons disease or Lewy body dementia.

What Is Parkinson Disease

Parkinson disease is a movement disorder. It can cause the muscles to tighten and become rigid This makes it hard to walk and do other daily activities. People with Parkinsons disease also have tremors and may develop cognitive problems, including memory loss and dementia.

Parkinson disease is most common in people who are older than 50. The average age at which it occurs is 60. But some younger people may also get Parkinson disease. When it affects someone younger than age 50, its called early-onset Parkinson disease. You may be more likely to get early-onset Parkinson disease if someone in your family has it. The older you are, the greater your risk of developing Parkinson disease. Its also much more common in men than in women.

Parkinson disease is a chronic and progressive disease. It doesnt go away and continues to get worse over time.

How Is Parkinsonism Diagnosed

You should be referred to a Parkinsons specialist for the diagnosis of any parkinsonism. They may wish to explore different things before giving you a diagnosis.

Your specialist will look at your medical history, ask you about your symptoms and do a medical examination.

Telling the difference between types of parkinsonism isnt always easy, for the following reasons:

  • The first symptoms of the different forms of parkinsonism are so similar.
  • In many cases, parkinsonism develops gradually. Symptoms that allow your doctor to make a specific diagnosis may only appear as your condition progresses.
  • Everyone with parkinsonism is different and has different symptoms.

One of the most useful tests to find out what sort of parkinsonism you may have is to see how you respond to treatment.

If your specialist thinks you have idiopathic Parkinsons, theyll expect you to have a good response to Parkinsons drugs such as levodopa . A good response means that your symptoms will improve. Sometimes, it will only be clear that youve responded to medication when the drug is reduced or stopped, and your symptoms become more obvious again.

If you dont have any response to Parkinsons medication, your specialist will have to look again at your diagnosis.

If you have both unusual symptoms and no response to Parkinsons drugs, this doesnt automatically mean you have another form of parkinsonism. But it will make your specialist want to reconsider your diagnosis.

Current tests available include:

Parkinson’s Misdiagnosis: Thyroid Issues

Conditions mistaken for Alzheimer’s

Thyroid issues affect muscle strength and can cause fatigue, muscle aches, stiffness, and joint pain. The early stages of Parkinsons could look similar to thyroid problems. However, with time and as a patient learns more about his or her own symptoms, they are able to provide a fuller picture, which can lead to a clearer diagnosis.

My husbands endocrinologist adjusted his thyroid medicine and was so surprised when he did not feel any better.

What Causes Parkinsons Disease

Parkinsons disease causes are still unknown. However, there is a vast amount of research directed at getting answers to its origin, treatment and prevention.

Parkinsons has been linked to declining levels of dopamine, an important brain chemical. Dopamine is a neurotransmitter. It plays a role in controlling movement and coordination. Parkinsons also causes the nerve endings to die on another neurotransmitter called norepinephrine. Norepinephrine controls automatic functions of the body, which contributes to Parkinsons symptoms such as fatigue, constipation and blood pressure changes .

Parkinsons Disease Caused By Stroke: Vascular Parkinsonism

A stroke involving the substantia nigra or basal ganglia is called vascular Parkinsonism. Similar to other strokes, damage is caused primarily by a lack of blood supply to these regions of the brain. Generally, the strokes associated with Parkinsonism are termed small vessel strokes as they arent normally catastrophic. Diagnosis of small vessel strokes can be confirmed with diagnostic tests such as CT or MRI of the brain.

It typically takes several small strokes to produce the symptoms of vascular Parkinsonism. In some cases, small vessel strokes can also produce a type of dementia called vascular dementia. As such, it is not unusual for people who have vascular Parkinsonism to also have vascular dementia.

What Are The Symptoms Of Parkinson Disease

Parkinson disease symptoms usually start out mild, and then progressively get much worse. The first signs are often so subtle that many people dont seek medical attention at first. These are common symptoms of Parkinson disease:

  • Tremors that affect the face and jaw, legs, arms, and hands
  • Slow, stiff walking

Parkinsons Disease: Symptoms, Diagnosis and Treatment  Healthsoul

Initially, Parkinsons disease causes physical symptoms. Problems with cognitive function, including forgetfulness and difficulty with concentration, may arise later. As the disease gets worse with time, many people develop dementia, which causes profound memory loss and makes it difficult to maintain relationships with others.

If you have Parkinsons Disease and dementia, eventually you will be faced with great difficulty living by yourself. Dementia will likely affect your ability to care for yourself, even if your current experience of Parkinsons Disease still means you can physically perform daily tasks. In these circumstances, we recommend seeking daily support from loved ones or professional carers who will be able to help you go about each day with less difficulty and confusion.
