# Symptoms and stages of multiple system atrophy
Multiple system atrophy progresses in stages in which progressively more brain regions are affected. The symptoms do not follow a fixed pattern — the order and severity vary greatly from person to person. This tab describes what typically happens in each stage and what is noticeable in daily life.
Early stage (first 1-3 years after diagnosis)
In the early stage, symptoms are often still mild and can be easily mistaken for something else. Most people can still live independently, but gradually notice that activities become more difficult.
**Motor symptoms** (movement and muscle control)
- Stiffness in arms, legs or neck, especially after rest
- Slower movements and difficulty initiating movements
- Mild tremor (shaking), usually not in both hands equally
- Slightly unsteady gait or feeling that you have less balance control
- Reduced arm swing when walking
- Muscle cramps or slight loss of muscle strength
**Autonomic symptoms** (unconscious bodily functions)
- Dizziness or blurred vision when standing up (orthostasis)
- Disturbed sleep, often with vivid nightmares or violent movements during sleep
- Erectile dysfunction
- Excessive sweating or very little sweating
- Disturbed bowel function (constipation is common)
- Bladder disorders: difficulty emptying or unwanted leakage
**Cognitive symptoms**
- Mild difficulty with concentration and memory
- Somewhat more difficulty with complex tasks
- Feeling of mental fogginess
**In daily life** this usually means that:
- You do things somewhat more stiffly or move more cautiously
- You notice that you wake up stiff in the morning
- You feel tired more quickly, mentally and sometimes physically
- Toilet visits become less predictable
- You can still go to work, but concentration requires more effort
The early stage can last months to years, but this varies greatly. Research shows that magnetic resonance imaging (MRI) can reveal certain changes in brain structure early on that predict how quickly the disease progresses. However, this data applies to patient groups as a whole; how quickly it progresses in one person depends on many individual factors that are not all known.
Middle stage (usually year 2-5)
In this stage, symptoms become more pronounced and the impact on daily life becomes more noticeable. Many people are diagnosed in this stage, as the features of MSA become more evident.
**Motor symptoms sharpen**
- Clear muscle rigidity (rigidity), especially in trunk muscles
- Gait becomes more unsteady and cautious; many people now use a cane or walker
- Falls become more likely, especially due to loss of balance without warning
- Movements are slower and more difficult to initiate ("freezing" — temporary halting of movement)
- Handwriting becomes smaller and shakier
- Speech becomes quieter and less clear
- Swallowing can become difficult, especially with solid food
**Autonomous symptoms intensify**
- Orthostasis (dizziness upon standing) may now be clearly present and increase fall risk
- Bladder dysfunction becomes clearer: many cannot empty completely or experience leakage
- Bowel function very slow; constipation is the rule
- Sexual dysfunction is usually clearly present
- Temperature regulation worsens; unexpected cold or heat waves
- Sleep apnea may occur (brief stops in breathing during sleep)
- Sleep remains severely disrupted
**Cognitive and emotional changes**
- Concentration and planning become noticeably more difficult
- Memory for new information declines
- Impulse control may change; emotions feel less filtered
- Depression occurs frequently
- Anxiety, especially before going out in public
**In daily life:**
- Work becomes impossible for many people
- Independent living becomes more difficult; help with household tasks and personal care becomes necessary
- Driving usually stops due to instability and reaction time
- Showering, dressing and toileting require help or home adaptations
- Social activities decrease due to fatigue and movement limitations
Strong data on the duration of this phase are lacking. Studies suggest that nutritional status and weight loss in this phase may be predictive of later complications, but this says nothing about the speed of progression in individual patients.
Advanced phase (usually year 5+)
In the advanced phase, independent mobility is usually no longer possible and many daily functions are severely limited. Care becomes intensive.
**Motor decline**
- Near complete loss of ability to walk independently; wheelchair is necessary
- Stiffness may become so severe that joint movement is limited
- Fine motor skills (writing, buttoning, eating) are severely limited or lost
- Speech is very unclear or absent; communication requires alternative means
- Swallowing is severely impaired; many patients require tube feeding
- Breathing and cough reflexes may weaken
**Autonomic complications**
- Orthostasis is extreme; lying down is often better than sitting
- Bladder dysfunction may require catheterization
- Sleep apnea may become more severe; sleep problems remain serious
- Temperature control is very disrupted
- Heart rhythm may become irregular
- Infections (urinary tract infections, pneumonia) become more likely
**Cognitive status**
- Dementia may occur, although not always
- Attention and memory are severely limited
- Personality may change
**In daily life:**
- Full care needed for personal hygiene and mobility
- Spending much time in bed or wheelchair
- Feeding via feeding tube
- Catheter may be needed
- Intensive home care or nursing home admission usually needed
- Communication severely limited
End stage
The end stage is characterized by severe organ failure and complications. Most deaths in MSA are related to respiratory complications, infections, or sudden autonomic instability.
**Clinical features:**
- Severely diminished consciousness or coma
- Severe breathing problems
- Swallowing and chewing reflex nearly absent
- Frequent pneumonia and infections
- Heart rhythm irregularities
- Possible: ventilation requirement (artificial ventilation)
**Survival in MSA overall:**
Population studies show that median survival (the point at which half of a group is still alive) after diagnosis averages **7 to 10 years** (figures vary in different studies from 2020-2025). However:
- This is an average across large groups; individual course varies greatly
- Some live shorter (4-5 years), others longer (15+ years)
- Speed depends on many factors: which brain areas are affected first, body composition, additional illnesses, infection risks
- No doctor can say for any one person how much time remains; it is impossible to estimate accurately
Only at population level are there some indications that certain MRI patterns and rapid weight loss early in the disease may be associated with faster progression, but this also tells nothing about any one person.
When to contact the healthcare provider
Contact your doctor or hospital if you notice:
- Sudden worsening of movement or balance, especially with repeated falls
- Severe dizziness when changing position (e.g. getting up)
- Difficulty swallowing or speech quality declining rapidly
- Fever, pain when urinating or bloody urine
- Coughing, panting or shortness of breath, especially at night
- Major changes in heart rate or irregularity
- Significant weight loss in a short time
- Changes in mental state: confused thinking, extreme drowsiness or agitation
