Atypical Parkinsonism Management

Introduction

Being told that you or someone you love may have atypical parkinsonism is unsettling. The name itself can be confusing — it sounds like Parkinson’s disease, but doctors use the word “atypical” to signal that something is different. The symptoms may have come on faster than expected, balance problems may have appeared early, or the usual Parkinson’s medication may not have worked as hoped. These differences are what bring most families to a specialist.

Atypical parkinsonism is not a single illness. It is an umbrella term for a small group of progressive brain conditions that share some features with Parkinson’s disease but follow their own paths. There is currently no cure, but a great deal can be done to manage symptoms, keep people safer at home, support thinking and speech, and ease the burden on caregivers.

This guide is written for patients who have received a diagnosis or are in the middle of being evaluated, and for the family members who walk alongside them. It explains the main types of atypical parkinsonism, how doctors reach a diagnosis, what treatment and rehabilitation usually involve, and how to plan for the months and years ahead.

What Is Atypical Parkinsonism?

Atypical parkinsonism — sometimes called “Parkinson-plus” syndromes — refers to neurodegenerative conditions that cause some of the same movement problems as Parkinson’s disease (slowness, stiffness, balance problems, tremor) but also involve additional features that Parkinson’s disease typically does not, especially early in the illness.

In Parkinson’s disease, brain cells that make a chemical messenger called dopamine gradually die. Replacing dopamine with medication usually helps. In atypical parkinsonism, the damage is more widespread. It affects not only the dopamine system but also other parts of the brain that control balance, eye movements, blood pressure, bladder function, speech, swallowing, and thinking. Because the damage is wider, dopamine replacement helps less, and other symptoms become prominent.

Key features that distinguish atypical parkinsonism from Parkinson’s disease include:

• Earlier and more severe balance problems and falls
• Limited or short-lived response to levodopa, the standard Parkinson’s medication
• Faster overall progression of symptoms
• Early problems with autonomic functions such as blood pressure, bladder, and bowel control
• Early changes in eye movements, speech, swallowing, or thinking
• Stiffness or weakness that is more pronounced on one side of the body (in some forms)

Identifying which type of atypical parkinsonism a person has matters because each type has its own pattern of symptoms, its own pace of change, and its own priorities for management.

Types of Atypical Parkinsonism

Multiple System Atrophy (MSA)

Multiple system atrophy involves the buildup of a protein called alpha-synuclein in cells called oligodendrocytes, which support nerve cells. MSA is usually divided into two patterns based on which symptoms dominate:

• MSA-P (parkinsonian type): Slowness, stiffness, and balance problems are most prominent.
• MSA-C (cerebellar type): Problems with coordination, walking, and speech (a slurred or sing-song quality) are more prominent.

Both forms involve autonomic failure — problems with blood pressure regulation (especially a drop on standing, called orthostatic hypotension), bladder control, sexual function, and sometimes breathing during sleep. Many people have noisy breathing or stridor at night.

Progressive Supranuclear Palsy (PSP)

PSP is caused by the buildup of a protein called tau. Its hallmark features include:

• Backwards falls early in the illness, often without warning
• Difficulty moving the eyes, especially looking down (vertical gaze palsy)
• A staring expression and reduced blinking
• Slurred speech and swallowing difficulty
• Stiffness of the trunk and neck more than the limbs
• Changes in behaviour, judgment, or thinking speed

Several variants of PSP exist. The classic form is called PSP-Richardson syndrome. Others may look more like Parkinson’s disease in the early years before showing the typical PSP picture.

Corticobasal Degeneration (CBD)

CBD also involves tau protein. It typically causes very asymmetric symptoms — one arm or leg is much more affected than the other. Features may include:

• Stiffness, jerks, and clumsiness on one side
• A feeling that a limb does not belong to the person (“alien limb” phenomenon)
• Difficulty performing learned movements such as dressing or using utensils (apraxia)
• Speech and language difficulties
• Changes in thinking and behaviour

The clinical picture is sometimes called corticobasal syndrome (CBS), because similar symptoms can be caused by other underlying brain diseases identified only at autopsy.

Dementia with Lewy Bodies (DLB)

DLB involves alpha-synuclein deposits called Lewy bodies in the cortex and other brain regions. It causes parkinsonism together with prominent thinking and perceptual changes, often early in the illness:

• Fluctuating attention and alertness, sometimes hour to hour
• Detailed visual hallucinations (often of people or animals)
• Acting out dreams during sleep (REM sleep behaviour disorder), sometimes years before other symptoms
• Sensitivity to certain antipsychotic medications
• Parkinsonism that may respond modestly to levodopa

DLB sits at the boundary between movement disorders and dementia, and is often managed jointly by neurologists and old-age psychiatry teams.

Causes and Risk Factors

The underlying cause of atypical parkinsonism is the gradual buildup of abnormal proteins in specific brain cells, followed by the death of those cells. The conditions are grouped scientifically by which protein is involved:

• Synucleinopathies (alpha-synuclein): MSA and DLB
• Tauopathies (tau protein): PSP and CBD

Why these proteins accumulate is not fully understood. Most cases occur in people with no clear family history. Known and suspected contributing factors include:

• Age: Symptoms most commonly begin between the ages of 50 and 70.
• Genetics: A small minority of cases run in families. Certain genetic variants have been linked with increased risk, but for most patients no genetic cause is found.
• Sex: MSA appears slightly more often in men than in women.
• Environmental factors: Research has explored possible links with chemical exposures and other influences, but nothing has been confirmed as a cause.

It is important to know that nothing a person did or did not do caused atypical parkinsonism. Diet, stress, and lifestyle did not bring it on, although healthy habits can help with overall resilience once symptoms begin.

Recognising Progression: Symptoms to Watch For

Most readers of this article already know that something is wrong — what matters now is recognising new symptoms early so they can be addressed. The list below is not for first-time diagnosis but for tracking changes that should be discussed with your specialist.

Movement and balance

• New or more frequent falls, especially backwards
• Difficulty turning in bed, getting out of a chair, or walking through doorways
• Worsening stiffness in the neck or trunk
• Freezing or sudden stops when walking

Speech, swallowing, and eyes

• Quieter, slurred, or strained speech
• Coughing while eating or drinking, or food “going down the wrong way”
• Difficulty looking up or down, blurred vision, or trouble reading
• Reduced blinking, dry eyes, or burning sensation in the eyes

Autonomic symptoms

• Lightheadedness or fainting on standing
• Bladder urgency, frequency, or incontinence
• Constipation
• Erectile or other sexual difficulties
• Excessive sweating or temperature problems
• Noisy breathing or loud snoring at night

Thinking, mood, and sleep

• Slower thinking or trouble planning tasks
• Memory or attention lapses
• Visual hallucinations
• Acting out dreams
• Apathy, low mood, or anxiety

Diagnosing atypical parkinsonism is one of the more challenging tasks in neurology. There is no single blood test or scan that confirms it. Specialists rely on a careful clinical assessment over time, supported by imaging and other investigations.

Neurological examination

A movement disorder specialist looks for the specific patterns that distinguish atypical parkinsonism from Parkinson’s disease. They will examine eye movements, posture and gait, muscle tone and reflexes, speech, swallowing, and thinking. They will also check blood pressure lying and standing to look for autonomic problems.

Trial of levodopa

Because Parkinson’s disease usually responds well to levodopa, a trial of this medication often forms part of the assessment. A clear, sustained response points more towards Parkinson’s disease, while a poor or short-lived response is one of several clues towards an atypical condition.

Brain imaging

• MRI of the brain: Can show patterns of shrinkage in specific regions — for example, the cerebellum and brainstem in MSA, the midbrain in PSP (sometimes producing a “hummingbird” appearance), or one-sided cortical changes in CBD. MRI also rules out other causes such as strokes or hydrocephalus.
• Dopamine transporter (DaT) scan: Confirms loss of dopamine nerve endings but does not separate Parkinson’s disease from atypical parkinsonism.
• PET imaging: Used in selected centres to look at metabolism in different brain regions.

Other tests

• Autonomic function tests: Measure blood pressure and heart rate responses to standing, breathing, and other manoeuvres.
• Sleep study (polysomnography): Identifies REM sleep behaviour disorder, sleep-related breathing problems, or stridor.
• Neuropsychological testing: Maps specific patterns of thinking changes, which can help distinguish the conditions.
• Urodynamic studies: Used when bladder symptoms are prominent.

The Movement Disorder Society has published consensus diagnostic criteria for MSA, PSP, and DLB. These criteria help specialists describe how likely a diagnosis is — possible, probable, or established — and are updated as research progresses. Because clinical features can evolve, an initial diagnosis may be revised at follow-up visits.

Treatment and Management

There is currently no treatment that halts or reverses atypical parkinsonism. Management focuses on relieving symptoms, preventing complications, supporting independence for as long as possible, and providing comfort and dignity throughout the course of the illness. Care is almost always team-based, involving a neurologist or movement disorder specialist alongside therapists, nurses, and other clinicians.

Medications for movement symptoms

• Levodopa: Often tried because some patients with MSA-P, PSP, or DLB get partial benefit. Doctors typically push the dose to a meaningful level before concluding that a person is not responding.
• Dopamine agonists, amantadine, and MAO-B inhibitors: May be considered in selected cases, with attention to side effects such as confusion, hallucinations, and low blood pressure.
• Botulinum toxin injections: Sometimes used for focal problems such as excessive saliva, eyelid spasm, or limb dystonia (sustained muscle pulling).

Medications for non-motor symptoms

• Orthostatic hypotension: Treated with measures such as raising the head of the bed, compression stockings, increased salt and fluid intake where safe, and medications such as midodrine or fludrocortisone.
• Bladder symptoms: Managed with bladder training, scheduled toileting, and medications when needed. Urology input is often valuable.
• Constipation: Addressed with fluids, fibre, exercise, and laxatives.
• REM sleep behaviour disorder: Often improves with melatonin or, in some cases, low-dose clonazepam.
• Mood symptoms: Depression and anxiety are common and treatable. Specialists usually prefer antidepressants with fewer movement-related side effects.
• Cognitive symptoms in DLB: Cholinesterase inhibitors such as rivastigmine and donepezil are considered, with evidence supporting benefit on attention and hallucinations.
• Hallucinations and behavioural symptoms: Treated carefully. People with DLB and related conditions can be very sensitive to standard antipsychotic medications, and specialists usually avoid older antipsychotics. Quetiapine or clozapine may be considered in selected cases.

All medication changes involve trade-offs. For example, treatments for low blood pressure can worsen bladder symptoms, and treatments for bladder symptoms can affect thinking. Adjustments are made gradually with careful follow-up.

Procedures and surgical options

Deep brain stimulation, which can be very helpful in Parkinson’s disease, is generally not used in atypical parkinsonism because evidence does not support meaningful benefit. Procedures such as feeding tube placement (PEG) may be considered later in the illness when swallowing becomes unsafe; this is a deeply personal decision discussed in advance with the patient, family, and care team.

Rehabilitation and Therapy

Physiotherapy (physical therapy)

• Balance training and strategies to reduce falls
• Exercises to maintain strength and flexibility
• Gait training, including the use of walking aids
• Posture work to reduce neck and back stiffness
• Cueing techniques (visual or auditory) to help with freezing

Occupational therapy

• Strategies for dressing, bathing, eating, and other daily activities
• Home assessment to identify trip hazards and recommend grab rails, raised toilet seats, and other aids
• Energy conservation techniques
• Recommendations on seating, wheelchairs, and pressure care

Speech and language therapy

• Exercises to improve voice volume and clarity
• Communication aids when speech becomes difficult, ranging from simple letter boards to electronic devices
• Swallowing assessment and dietary modifications (such as thickened liquids or softer foods) to reduce the risk of choking and aspiration pneumonia

Other supportive therapies

• Dietitian input: To maintain nutrition as eating becomes slower or swallowing changes.
• Continence advisors: For practical strategies and equipment.
• Vision and orthoptic care: Especially important in PSP, where eye movement problems and dry eyes affect reading and walking safely.
• Psychological support: Counselling for the person living with the diagnosis and for family caregivers.

Lifestyle and Self-Management

While there is no diet or exercise programme that changes the underlying disease, day-to-day choices have a meaningful effect on safety, comfort, and wellbeing.

Movement and exercise

Most specialists encourage regular, structured activity tailored by a physiotherapist. Walking, stationary cycling, swimming or water-based exercise, and stretching are common components. Programmes such as supervised balance classes can be helpful where available. The aim is consistency rather than intensity.

Eating and drinking

• Eat in an upright position and take small bites and sips.
• Allow plenty of time for meals.
• Follow the speech therapist’s guidance on textures.
• Stay well hydrated unless fluid restriction has been advised for another reason.
• For people with orthostatic hypotension, smaller more frequent meals may help, as large meals can worsen blood pressure drops.

Sleep and bedroom safety

• Raising the head of the bed by 10–30 degrees can help with morning blood pressure and reflux.
• Move sharp objects and furniture away from the bedside in REM sleep behaviour disorder to prevent injury during dream enactment.
• Discuss any loud snoring, gasping, or stridor with your specialist; sleep studies and breathing support may be needed.

Home safety

• Remove loose rugs and clutter.
• Improve lighting, especially at night.
• Install grab rails in bathrooms and beside toilets.
• Consider a raised toilet seat, shower chair, and non-slip mats.
• Use a personal alarm or fall detection device if helpful.

Driving

Atypical parkinsonism affects reaction time, balance, eye movements, and judgment. Most specialists advise an honest, early conversation about driving safety, with formal assessment when appropriate. Many people stop driving earlier than they would have with Parkinson’s disease.

Monitoring and Follow-up

Because these conditions evolve over time, regular follow-up is central to good care. Visits with a movement disorder specialist or neurologist typically focus on:

• Reviewing new or changing symptoms
• Adjusting medications and weighing benefits against side effects
• Repeating blood pressure and autonomic checks
• Updating rehabilitation goals
• Screening for depression, anxiety, and caregiver strain
• Discussing equipment and home support as needs change
• Revisiting the diagnosis if features evolve unexpectedly

As atypical parkinsonism progresses, certain complications become more common. Knowing what to watch for helps families act early.

• Falls and fractures: Among the most common and serious complications. Early balance problems make falls a particular risk in PSP.
• Aspiration pneumonia: Caused by food, liquid, or saliva entering the airway when swallowing is unsafe. Often the most serious medical complication in advanced illness.
• Urinary tract infections: Common with bladder symptoms; can cause sudden worsening of confusion or mobility.
• Pressure injuries: Develop when mobility is very limited; prevented with regular repositioning and good seating.
• Severe blood pressure swings: Can cause fainting, falls, or hospital admission.
• Sleep-related breathing problems: Including obstructive sleep apnoea and, in MSA, stridor that may need overnight breathing support.
• Depression, anxiety, and social isolation: Affect both patients and caregivers.
• Caregiver burnout: A real medical issue that needs its own attention and support.

Living with Atypical Parkinsonism

The lived experience of atypical parkinsonism is shaped not only by symptoms but by the people, routines, and supports around the person. Families often describe the journey as a series of adjustments rather than a single decision.

Communicating about the diagnosis

Many people choose to share the diagnosis with close family and a few trusted friends, then decide gradually who else to tell. Children and grandchildren often cope better when they understand what is happening and what to expect. Support organisations and patient associations offer plain-language information that can help these conversations.

Work and activities

Depending on the type and pace of the illness, some people continue working for a time, often with modifications. Hobbies and meaningful activities can sometimes be adapted — for example, audiobooks when reading becomes hard, or seated gardening when balance is difficult. Staying engaged supports mood and quality of life.

Caregivers and the family

Caregiving is demanding, both physically and emotionally. Specialists encourage caregivers to:

• Accept practical help from family, friends, and community services.
• Use respite care when available, even briefly, to rest and recover.
• Pay attention to their own health, sleep, and mood.
• Connect with caregiver support groups, where the shared experience can be a relief in itself.

Advance care planning

Because atypical parkinsonism is progressive, many specialists encourage early conversations about future care preferences while communication and decision-making are still strong. Topics often include preferences around feeding tubes, hospital admissions, ventilation, and place of care. Palliative care teams — which focus on comfort, symptom control, and quality of life — can be involved at any stage and are not only for the final weeks of life.

Outlook

The course of atypical parkinsonism varies between conditions and between individuals. In general, these disorders progress more rapidly than Parkinson’s disease, but many people live a number of years after diagnosis, and the pace can be slower than initially feared. PSP, MSA, CBD, and DLB each have their own typical patterns, and your specialist can give a more personalised picture based on the specific diagnosis and how symptoms have evolved.

Outlook should not be measured only in years. The quality of those years — the ability to remain connected, comfortable, and supported — is shaped by the care plan, the rehabilitation effort, and the strength of the support network around the person. Many families report that even as the condition progresses, well-organised care brings real moments of stability, dignity, and meaning.

When to Seek Urgent Care

Some changes need prompt medical attention rather than waiting for the next scheduled appointment:

• Choking, breathlessness, or a suspected aspiration episode
• A fall with head injury, severe pain, or inability to bear weight
• Sudden, marked worsening of mobility, speech, or alertness
• New confusion, agitation, or hallucinations not previously present
• Signs of a urinary tract infection or pneumonia (fever, burning on urination, productive cough)
• Fainting or repeated severe lightheadedness on standing
• Loud noisy breathing or pauses in breathing during sleep (especially in MSA)
• Inability to swallow medications or fluids

Carrying a brief summary of the diagnosis, current medications, and the neurologist’s contact details can speed up emergency care, particularly because not all hospital teams are familiar with atypical parkinsonism.

Frequently Asked Questions

Is atypical parkinsonism the same as Parkinson’s disease?

No. Atypical parkinsonism shares some symptoms with Parkinson’s disease — particularly slowness, stiffness, and balance problems — but it includes additional features, progresses more quickly, and responds less well to levodopa. The underlying brain changes and the priorities for care are different.

How do doctors tell the difference between Parkinson’s disease and atypical parkinsonism?

The difference is usually made on careful clinical examination over time, supported by the response (or lack of response) to levodopa, brain MRI, and other tests such as autonomic function testing or sleep studies. An initial diagnosis is sometimes revised as the picture becomes clearer at follow-up visits.

Will my medications definitely not work?

Many people with atypical parkinsonism get some benefit from levodopa or other Parkinson’s medications, even if the response is partial or short-lived. Doctors typically trial these medications carefully before deciding whether to continue them. Medications for non-motor symptoms — such as low blood pressure, bladder problems, sleep, and mood — often help considerably.

Is there a cure or a treatment that slows the disease?

There is currently no treatment proven to halt or slow the progression of atypical parkinsonism. Research is active, and clinical trials are exploring drugs aimed at the underlying protein abnormalities. Symptom-focused treatment and rehabilitation remain the foundation of care.

Can deep brain stimulation help?

Deep brain stimulation, which can be very useful in Parkinson’s disease, is not generally used in atypical parkinsonism because evidence does not show meaningful benefit, and in some cases symptoms can worsen.

Is atypical parkinsonism inherited?

Most cases are not inherited. A small number of families have a genetic predisposition, and genetic testing is occasionally offered when there is a strong family history. For most patients, no clear genetic cause is found.

Can children develop atypical parkinsonism?

Atypical parkinsonism, as described in this article, is overwhelmingly an adult-onset condition, usually appearing after the age of 50. A few very rare genetic neurological disorders in children can cause parkinsonism-like features, but these are separate conditions, managed by paediatric neurologists with different priorities.

How long can someone live with atypical parkinsonism?

Survival varies significantly between conditions and individuals, and depends heavily on swallowing safety, falls, infection risk, and overall health. Most specialists prefer to give personalised estimates based on the specific diagnosis and how symptoms have progressed, rather than rely on general numbers.

Is palliative care only for the end of life?

No. Palliative care focuses on comfort, symptom control, and quality of life and can be helpful at any stage of a serious illness. Early involvement of palliative care teams has become more common in atypical parkinsonism because of the complexity of symptoms.

What can family members do to help most?

Practical help with daily tasks, a calm environment, attention to safety at home, and emotional companionship all matter. So does looking after the caregiver’s own health. Many families also find that learning about the specific type of atypical parkinsonism — through trusted patient organisations — helps them anticipate and plan rather than react.

Conclusion

Atypical parkinsonism is a challenging diagnosis, but it is not a story without options. Each of its main forms — MSA, PSP, CBD, and DLB — has its own pattern, and each responds to a thoughtful, multidisciplinary plan that combines medication, rehabilitation, supportive care, and family-centred planning.

The most useful steps for most patients and families are early involvement of a movement disorder specialist, consistent rehabilitation, attention to home safety and swallowing, careful management of non-motor symptoms, and honest conversations about preferences for future care. With these foundations in place, day-to-day life can stay as comfortable and meaningful as possible, even as the condition changes over time.
