Multiple System Atrophy is a rare, progressive neurodegenerative condition in which alpha-synuclein protein accumulates in oligodendrocytes (brain support cells) — not neurons, as in Parkinson's Disease. This damages multiple brain systems simultaneously: the basal ganglia (movement), cerebellum (balance and coordination), and autonomic nervous system (blood pressure, bladder, and sexual function). MSA presents in two forms: MSA-P (Parkinson's-predominant) and MSA-C (Cerebellar-predominant). It is regularly misdiagnosed as Parkinson's Disease. The combination of Parkinson's-like movement symptoms with early, prominent autonomic failure (fainting on standing, bladder dysfunction, erectile dysfunction in men) is the key diagnostic signal for MSA.
- What it is
- Rare progressive condition damaging movement, balance, and autonomic nervous systems simultaneously. Alpha-synuclein accumulates in oligodendrocytes (not neurons as in PD). Average survival 7–10 years.
- Most important diagnostic clue
- Parkinson's-like movement + early, prominent autonomic failure (severe dizziness on standing, bladder problems, erectile dysfunction) = MSA until proven otherwise.
- Levodopa response
- Minimal or none — the most important distinguishing feature from Parkinson's Disease, which responds well initially.
- MRI hallmarks
- MSA-C: 'hot cross bun sign' in the pons · MSA-P: putamen signal changes + dark rim. Both require specialist MRI interpretation.
- Key autonomic treatments
- Fludrocortisone (blood pressure) · Midodrine (blood pressure) · Intermittent self-catheterisation (bladder) · Compression stockings · Dietary salt/fluid
- Dangerous complication
- Laryngeal stridor (vocal cord paralysis) — can obstruct airway during sleep. New nocturnal noisy breathing in an MSA patient requires urgent review.

About This Condition
What Is Multiple System Atrophy?
Multiple System Atrophy — MSA is a rare, progressive brain condition that does something most neurological diseases do not: it attacks multiple systems simultaneously. Not just the movement system, not just the balance system, not just the body's automatic functions all of them, in varying combinations, progressively failing over years.
This is where the name comes from. "Multiple system" refers to the several distinct neurological systems that are affected: the movement control system (basal ganglia), the coordination and balance system (cerebellum), and the autonomic nervous system the part of the nervous system that runs the body's background functions without conscious thought: blood pressure regulation, bladder control, bowel function, sweating, digestion, and sexual function.
When these systems fail together, the resulting clinical picture is complex and often confusing partly because the mix of symptoms varies considerably between individuals. One person with MSA may look very much like someone with Parkinson's Disease. Another may look more like someone with a balance and coordination disorder. And in both cases, there will be an additional layer of symptoms that neither Parkinson's nor a simple balance disorder fully explains: fainting when standing up, severe bladder problems, or loss of normal sweating the signature of autonomic failure.
MSA is rare affecting approximately 3–5 people per 100,000 and there is currently no cure and no treatment that slows its progression. It progresses faster than Parkinson's Disease, and average survival from symptom onset is around 7–10 years. These are honest facts that families need to know.
But accurate, timely diagnosis changes what is possible. Many MSA patients in India are managed for months or years under the wrong diagnosis, as Parkinson's Disease, as a cerebellar ataxia, or as separate cardiac or urological conditions. At KIMS Neuroscience, Hyderabad, our specialist movement disorders team has the clinical experience and the diagnostic tools to identify MSA correctly and to coordinate the multi-system management this condition demands.

040-44885000International enquiries: info@kimsneurosciences.comWhat Are the Two Types of MSA?
MSA presents in two distinct clinical patterns, depending on which systems are most affected early in the disease. Understanding this is important because MSA-P and MSA-C can look like completely different conditions at first glance.
MSA-P — Parkinsonism-predominant MSA
In MSA-P, the movement features of Parkinson's Disease predominate, stiffness, slowness, and balance problems. The person walks with a shuffling gait, moves slowly, and is stiff through the limbs and trunk. They may look, to a non-specialist, like a person with Parkinson's Disease.
But there are important differences from Parkinson's:
• Levodopa — the main Parkinson's medication improves symptoms in only a small percentage of MSA patients, and even that improvement is temporary. A person with MSA-P who receives levodopa will typically notice little to no benefit, or a brief, modest improvement that quickly fades
• Tremor at rest — the classical Parkinson's tremor is less prominent in MSA-P than in Parkinson's Disease
• Autonomic symptoms are prominent and appear relatively early dizziness on standing, bladder problems, and constipation alongside the movement difficulties
• The progression is faster than Parkinson's Disease
MSA-C — Cerebellar-predominant MSA
In MSA-C, the cerebellar features predominate problems with balance, coordination, and precise movement. The cerebellum is the part of the brain that controls the fine-tuning of movement, balance, and coordination. When it is damaged by MSA:
• Walking becomes wide-based and unsteady legs spread further apart than normal, steps are irregular, the person veers to one side
• Limb coordination is affected reaching for objects, precise hand movements, and rapid alternating movements become clumsy and inaccurate
• Speech becomes slurred in a specific way scanning dysarthria, where words are broken into syllables with irregular pauses, as if the brain is having difficulty coordinating the speech muscles in real time
• Eye movements become jerky and difficult to control smoothly
MSA-C is more common in people of Japanese, Korean, and East Asian ancestry. In European and South Asian populations, MSA-P is somewhat more common.
The Common Thread in Both Types — Autonomic Failure
Regardless of whether a patient presents as MSA-P or MSA-C, the autonomic nervous system is eventually affected in virtually all MSA patients. The autonomic symptoms are so consistent and so important that their presence alongside either movement pattern is a powerful diagnostic signal:
• Blood pressure that drops when standing up (orthostatic hypotension) this is the most important autonomic symptom. The person stands up and their blood pressure drops significantly, causing dizziness, lightheadedness, blurred vision, and sometimes fainting. In severe cases, they may only be able to stand for seconds before collapsing. Many patients first see a cardiologist for this before the neurological cause is identified.
• Bladder dysfunction urgency, frequency, incontinence, or difficulty fully emptying the bladder. Often one of the earliest autonomic symptoms. Many patients first see a urologist.
• Erectile dysfunction in men often one of the earliest symptoms of MSA in male patients, appearing before the movement or balance problems
• Constipation caused by impaired gut motility from autonomic failure
• Abnormal sweating reduced or absent sweating over the body, sometimes with compensatory excessive sweating in the face
What Causes Multiple System Atrophy?
MSA is caused by the abnormal accumulation of alpha-synuclein protein the same protein involved in Parkinson's Disease and Lewy Body Dementia but in a crucial and distinctive way. In Parkinson's and LBD, the alpha-synuclein accumulates inside neurons (nerve cells). In MSA, it accumulates primarily inside oligodendrocytes the support cells that produce the myelin sheath surrounding nerve fibres.
These abnormal protein deposits, called glial cytoplasmic inclusions (GCIs), are the defining pathological hallmark of MSA. They damage and eventually kill the cells in which they accumulate and these cells are found across multiple brain systems, which is why MSA affects so many functions simultaneously.
Why does alpha-synuclein accumulate in oligodendrocytes in MSA?
This is an active area of research and is not yet fully understood. MSA is classified as a synucleinopathy the same family as Parkinson's Disease and Lewy Body Dementia but the cell type affected and the clinical consequences are distinct.
Is MSA inherited?
MSA is a rare sporadic progressive neurological disorde meaning that in the overwhelming majority of cases, it occurs without any family history and without an identified genetic cause. Unlike Huntington's Disease or familial Parkinson's, MSA does not follow a clear inheritance pattern.
Having a family member with MSA does not significantly increase your own risk. This can sometimes be reassuring for families concerned about their own children's risk.
What increases MSA risk?
• Age — MSA typically begins between ages 50 and 60, and becomes more common with age
• No gender preference it affects men and women equally
• No confirmed modifiable environmental risk factors some research has suggested possible associations with solvent exposure and farming, but these are not established
Diagnosis at KIMS
How Is MSA Diagnosed at KIMS?
Diagnosing MSA accurately requires a specialist with experience in atypical Parkinsonian syndromes and a systematic investigation of both the movement and the autonomic nervous systems. Many people affected with MSA may first be incorrectly diagnosed as having Parkinson's Disease because of many similar features between the two conditions.
Step 1: A history focused on both movement and autonomic symptoms
The specialist will take a detailed history covering: • When movement or balance problems began, and how they have progressed. • Whether fainting or severe dizziness on standing has occurred; bladder and bowel symptoms. • Erectile dysfunction in male patients often an early symptom that patients are reluctant to mention but that the specialist will ask about directly. • The response to levodopa minimal or absent response in MSA is a diagnostic pointer. • REM sleep behaviour disorder acting out dreams which occurs in MSA as well as Parkinson's and LBD, reflecting the shared alpha-synuclein pathology.
Step 2: A thorough neurological examination
The specialist examines for: • Parkinsonian features — bradykinesia, rigidity, postural instability. • Cerebellar features — ataxic gait, limb dysmetria, nystagmus, scanning dysarthria. • Autonomic signs — lying and standing blood pressure measured in the clinic (a drop of 20mmHg systolic or 10mmHg diastolic on standing, confirmed on repeat testing, confirms orthostatic hypotension). • The speech pattern — the cerebellar dysarthria of MSA-C has a distinctive quality.
Step 3: Autonomic function testing
Formal testing of the autonomic nervous system is essential and is one of the most important distinguishing features of MSA. Tests include: • lying and standing blood pressure recording — a simple, practical test performed in clinic that confirms orthostatic hypotension; • Thermoregulatory sweat test — assesses the integrity of the sympathetic nerve supply to sweat glands; a specific pattern of sweat loss supports MSA; • Heart rate variability testing — assesses the autonomic control of the heart; • Urodynamic studies — if bladder symptoms are prominent, this specialised test maps the pattern of bladder dysfunction.
Step 4: Brain MRI — the hot cross bun sign
MRI of the brain in MSA can show characteristic changes that support the diagnosis. In MSA-C, the pons a structure in the brainstem shows a distinctive pattern called the "hot cross bun sign" on T2-weighted imaging. This reflects the degeneration of specific fibre tracts within the pons that cross each other at right angles, creating a cross-shaped signal change that on a horizontal MRI slice looks like the iced cross on a hot cross bun. In MSA-P, the putamen, a structure in the basal ganglia may show characteristic signal changes, including a thin, dark rim and reduced signal intensity compared to normal. Like the hummingbird sign in PSP, these MRI findings are specific enough to be diagnostically useful but subtle enough to be missed by a radiologist without experience in atypical Parkinsonian conditions. At KIMS Neuroscience, Hyderabad, our neurologists review MRI images specifically for these findings.
Step 5: DaTscan
A DaTscan in MSA typically shows reduced dopamine transporter activity in the striatum similar to what is seen in Parkinson's Disease. This means DaTscan alone cannot reliably distinguish MSA from Parkinson's Disease. However, when taken together with poor levodopa response, prominent autonomic failure, and the MRI findings, the overall picture allows confident distinction between the two conditions.
Distinguishing MSA from its Closest Mimics
| Feature | MSA | Parkinson's | PSP |
|---|---|---|---|
| Levodopa response | Minimal / none | Good initially | Minimal / none |
| Autonomic failure | Prominent and early | Mild and late | Mild |
| Falls | Present | Late | Early backwards |
| Cerebellar features | Yes (MSA-C) | No | No |
| MRI sign | Hot cross bun / putamen | Normal | Hummingbird |
| Eye movements | Usually normal | Usually normal | Vertical gaze palsy |
Treatment
How Is MSA Treated at KIMS?
There is no cure for MSA and no treatment that slows its progression. Management at KIMS Neuroscience is multidisciplinary and targets each symptom domain movement, balance, autonomic failure, bladder function, and palliative support with specific interventions. There are no treatments to stop or slow the progression of MSA, but there are treatments to help people cope with the symptoms.
Managing orthostatic hypotension — the most disabling autonomic symptom
Blood pressure that drops dangerously on standing is not just uncomfortable it is a serious fall risk and can cause loss of consciousness. Managing it is a priority. Non-medication measures first: Increasing fluid and salt intake more water and more dietary salt helps maintain blood volume and supports blood pressure. Compression stockings and abdominal binders these garments physically prevent blood pooling in the legs and abdomen when standing. Raising the head of the bed at night sleeping with the head slightly elevated reduces overnight blood pressure fluctuations. Eating smaller, more frequent meals large meals divert blood to the gut and can worsen postural hypotension. Avoiding hot environments and alcohol both dilate blood vessels and worsen blood pressure drops. Medications when needed: Fludrocortisone, a synthetic mineralocorticoid that helps the kidneys retain salt and water, increasing blood volume. Midodrine, a medication that constricts blood vessels and raises blood pressure; taken in specific doses during the day, timed around planned activity. Pyridostigmine, can help some patients with mild-to-moderate orthostatic hypotension.
Managing bladder dysfunction
Bladder symptoms in MSA are caused by both overactivity of the detrusor muscle (causing urgency and frequency) and impaired relaxation of the sphincter (causing incomplete emptying). Treatment depends on the pattern: Overactive bladder symptoms anticholinergic medications (oxybutynin, solifenacin) or beta-3 agonists (mirabegron) reduce urgency and frequency. Incomplete emptying, intermittent self-catheterisation, taught by a specialist nurse, allows complete bladder emptying and prevents urinary tract infections. Combined symptoms, a urodynamics study guides the most appropriate management. Our team coordinates closely with urology at KIMS to manage bladder symptoms comprehensively.
Movement and balance treatment
Levodopa is worth a careful trial in MSA-P. A small percentage of MSA patients do experience some improvement, and it is worth establishing whether the individual patient responds. If there is a meaningful benefit, levodopa is continued. If not, it is discontinued to avoid unnecessary side effects. Physiotherapy in MSA must address both the Parkinsonian features (stiffness, slow initiation of movement) and the cerebellar features (balance, coordination) where both are present. Falls prevention is central an early home safety assessment and provision of appropriate walking aids are essential. Approximately 50% of MSA patients are wheelchair-bound within 5–6 years of motor symptom onset planning for this transition proactively, rather than managing a crisis when it happens, makes a significant difference to how the family copes.
Speech and swallowing
The speech and swallowing difficulties in MSA are managed in the same way as in PSP and ALS with regular speech therapy assessment, communication strategies, dietary texture modification as swallowing deteriorates, and consideration of a PEG feeding tube when oral nutrition becomes unsafe or inadequate. One specific risk in MSA that deserves mention: laryngeal stridor, a high-pitched, harsh breathing sound caused by partial paralysis of the vocal cords. This can develop in MSA and in severe cases poses a risk to the airway, particularly during sleep. Our respiratory and ENT teams monitor for this and manage it with CPAP or in more severe cases surgical intervention.
Managing other autonomic symptoms
Constipation dietary fibre, adequate hydration, and laxatives. Reduced sweating avoiding overheating, staying in cool environments. Sexual dysfunction phosphodiesterase inhibitors (sildenafil) can help with erectile dysfunction in MSA, but must be used cautiously given the blood pressure sensitivity.
Palliative care from diagnosis
The same principle we have applied in every condition with a poor prognosis applies in MSA: palliative care begins at diagnosis, not at the end of life. The questions of what the patient wants for their future ventilation, feeding tubes, resuscitation preferences are raised calmly, early, and in the patient's own words. The KIMS Neuroscience palliative care team is available from the outset.
When Should You Seek a Specialist Assessment for MSA?
Come to KIMS Neuroscience, Hyderabad for a specialist evaluation if the symptoms suggest Multiple System Atrophy rather than typical Parkinson's Disease. Early specialist assessment helps ensure the right diagnosis, the right management plan, and timely support for both patients and families.
A second opinion is always reasonable when a diagnosis of Parkinson's Disease is not matching the clinical picture. KIMS Neuroscience accepts direct appointments no referral letter is needed. Call 040-44885000 Monday to Saturday.
A family member has been diagnosed with Parkinson's Disease but levodopa has provided minimal benefit
Movement or balance problems are accompanied by significant dizziness or fainting on standing up
A man in his 50s or 60s develops erectile dysfunction alongside movement or balance problems — this combination is a characteristic early pattern of MSA
Bladder urgency, frequency, or incontinence is prominent and appeared alongside or before movement problems
Walking has become wide-based and unsteady in a way that resembles poor coordination rather than stiffness
Speech has become slurred with an irregular, syllable-by-syllable quality
The person is experiencing episodes of a harsh, high-pitched noise when breathing — particularly at night
What to Expect — Living with MSA
MSA progresses faster than Parkinson's Disease. Average survival from symptom onset is 7–10 years, though this varies. Approximately 50% of people with MSA are wheelchair-bound within 5–6 years of motor symptom onset. The most common causes of death are aspiration pneumonia, sudden respiratory failure (sometimes related to laryngeal stridor), and the complications of immobility.
Managing the autonomic symptoms particularly the blood pressure drops and bladder problems early and consistently makes the biggest practical difference to daily function and safety in the first few years. Falls from orthostatic hypotension are preventable with the right medications and behavioural strategies. Bladder infections from incomplete emptying are preventable with appropriate bladder management.
For families in Hyderabad and Telangana: MSA is rare, which means most general neurologists encounter it infrequently. Specialist movement disorders experience which the KIMS Neuroscience team has makes a real difference to diagnostic accuracy, appropriate management, and the honest conversations about the future that families need. You should not have to spend months or years being treated for the wrong condition.
