Multiple system atrophy (MSA) is a rare, degenerative neurological disorder that gradually affects multiple functions of the autonomous nervous system. The symptoms of MSA develop slowly over time as damage to nerve cells in different parts of the brain gradually worsens. This causes disability in movement, speech, swallowing, and bladder and bowel control.

Multiple System Atrophy (MSA) Causes And Symptoms

The exact cause of MSA is unknown, but dysfunction and loss of nerve cells known as oligodendrocytes and neurons in specific brain regions are involved. This leads to degeneration and atrophy in different systems of the body controlled by the autonomic nervous system.

The Major Symptoms Of MSA Include:

- Movement Problems: Problems with movement known as parkinsonism, such as tremors, rigid muscles, difficulty starting or continuing movement, and loss of balance and coordination.

- Autonomic Dysfunction: Issues regulating involuntary bodily functions like blood pressure, bladder control, bowel control, sweating and swallowing. This includes symptoms ...
... like erectile dysfunction, severe constipation/incontinence, excessive daytime sleepiness, and orthostatic hypotension.

- Speech and Communication Issues: Slurred or slowed speech, weakness of the vocal cords, swallowing difficulties leading to aspiration, and trouble writing or using utensils.

The symptoms of MSA tend to worsen progressively with no periods of remission. Symptoms vary among individuals but movement, autonomic and speech/swallowing problems frequently occur. Not all symptoms affect every person.

Multiple System Atrophy (MSA) Diagnosis

MSA is difficult to diagnose in early stages as symptoms resemble other conditions like Parkinson's disease. Several tests are used to rule out other causes, evaluate symptoms, and support a clinical diagnosis of probable MSA.

Tests may include:

- Brain MRI: Can rule out other causes but not diagnostic of MSA. Changes in MSA brain areas may appear later in disease course.

- DAT scans: Shows loss of dopamine transporters in basal ganglia, supporting diagnosis of MSA-P subtype.

- Ultrasound of walls of digestive tract: Detects layer thickening supporting MSA diagnosis.

- Autonomic testing: Orthostatic vital sign changes, sweating tests, etc. support autonomic failure diagnosis in MSA.

No single test can definitively diagnose MSA. Physicians rely on evaluation of medical history, neurological exam findings and test results to diagnose probable MSA based on established consensus criteria. A definitive diagnosis still requires brain tissue examination after death.

Subtypes And Prognosis

There are two major subtypes of MSA depending on which system is primarily affected early in the disease course:

- MSA with predominant parkinsonism (MSA-P): Features rigid, slow movements resembling Parkinson's disease.

- MSA with predominant cerebellar ataxia (MSA-C): Main early feature is problems with coordination, balance and speech.

On average, the life expectancy after MSA symptom onset is 6-10 years, though significant variability exists among individuals. Dependency in daily activities increases over time as functions decline. Some experience more rapid progression while others live longer with milder symptoms. There is no cure for MSA and current treatments only aim to manage symptoms.

Treatment And Management

A multidisciplinary approach is recommended as MSA symptoms impact mobility, self-care and quality of life. Management may include:

- Medications to improve parkinsonism, autonomic and urinary symptoms. But effectiveness is limited as MSA does not respond well to standard Parkinson's drugs.

 
- Physical, occupational and speech therapies help maintain abilities and adaptive techniques.

- Caregiver support as disabilities increase over time and assistance needs grow.

- Nutritional supplementation if unable to eat or swallow properly.

- Assistive devices like canes, walkers, wheelchairs as needed with disease progression.

- Procedures may help if severely impacted, like botulinum toxin injections for drooling or urinary catheter placement.

The goals are to relieve symptoms, maximize functioning, and improve safety and comfort as the disease advances. Palliative care also aims to enhance quality of life during end-stage disease.
