What triggers MSA?
The cause of MSA is unknown. The vast majority of cases are sporadic, meaning they occur at random. A distinguishing feature of MSA is the accumulation of the protein alpha-synuclein in glia, the cells that support nerve cells in the brain.
What affects MSA?
Multiple system atrophy (MSA) is a rare condition of the nervous system that causes gradual damage to nerve cells in the brain. This affects balance, movement and the autonomic nervous system, which controls several basic functions, such as breathing, digestion and bladder control.
What part of the brain does multiple system atrophy affect?
MSA causes deterioration and shrinkage (atrophy) of portions of your brain (cerebellum, basal ganglia and brainstem) that regulate internal body functions, digestion and motor control.
What are the early signs of MSA?
What are the symptoms of MSA? Most often, the first clinical symptom a patient will note will be lightheadedness, dizziness, and episodes of passing out, but the first symptoms in some patients may include difficulty initiating movement, body stiffness, urinary incontinence, and increased falls.
How quickly does MSA progress?
How fast does MSA progress? Unfortunately, MSA progresses rapidly. It starts at an average age of 54 and within only 2 or 3 years produces important disability with regard to walking and balance. Most people with MSA are wheelchair-bound by the 4th year and eventually become bedbound because of general stiffness.
Is MSA worse than Parkinsons?
A major clinical dilemma is whether a patient with parkinsonism has Parkinson disease (PD) or MSA, as the prognosis of MSA is much worse. Autonomic involvement is common in PD but is more variable in severity than MSA. Mild OH is relatively common in PD and occasionally severe OH can occur.
Is MSA a terminal illness?
Because MSA is at this time a terminal disease with mean patient survival of 6 to 10 years after the onset of symptoms, patients and families should begin to make decisions regarding advanced directives, finances, hospice care, and the possibility of brain donation, if so desired.
What causes death in MSA patients?
Patients with MSA have been reported to die of respiratory infection, sudden death, choking, cancer, suicide, and stroke, among other causes [5, 11-18]. The frequency of different causes of death in MSA is inconsistent across studies.
Does MSA have stages?
In MSA there may be several stages — alpha-synuclein accumulates in the oligodendroglial cells, then there is failure of mitochondrial function as well as loss of trophic factor support. Then the oligodendroglia degenerate, followed by microglia and astroglial activation.
Is there pain with MSA?
Pain was reported in 47% of the MSA patients. It was classified as rheumatic in 64% of MSA patients reporting pain, sensory in 28%, dystonic in 21%, and levodopa-related in 16%, mostly related to off-period or diphasic dystonias. There was a mixed pain syndrome in 19% of these patients.
Does MSA cause dementia?
The disorder is characterized by postural (or orthostatic) hypotension (an excessive drop in blood pressure when the patient stands up), which causes dizziness or momentary blackouts. MSA does not provoke dementia but could impair some cognitive functions.
How is MSA treated?
There is no specific treatment for MSA. Treatment is aimed at controlling the symptoms of the disease. Drugs that are used to treat people with Parkinson’s disease, most notably levodopa (given in tablets of Sinemet), may also be prescribed for individuals with MSA.
Does MSA show up on MRI?
MRI is useful and indispensable in the diagnosis of MSA and also possibly for monitoring disease progression.
Is MSA similar to ALS?
It is considered a rare disease, similar in frequency to the more well-known neurodegenerative disease amyotrophic lateral sclerosis or Lou Gehrig’s disease. Though MSA has not traditionally been considered a genetic disease, new evidence is emerging supporting some genetic predisposition in many patients.
How rare is multiple system atrophy?
Multiple System Atrophy (MSA) is a debilitating neurodegenerative disease. It is rare, affecting only about four in 100,000 people, but its impact on those it touches is devastating.
Is multiple system atrophy fatal?
Multiple system atrophy is a progressive, fatal disorder that makes muscles stiff (rigid) and causes problems with movement, loss of coordination, and malfunction of internal body processes (such as blood pressure and bladder control).
How is MSA different from Parkinsons?
Both diseases seem to have some connection with environmental contaminants. One key difference is that the nerve destruction in Parkinson’s tends to occur in the areas of the brain that control movement, whereas MSA affects what’s called the autonomic nervous system.
How is multiple system atrophy inherited?
Multiple system atrophy is a complex condition that is likely caused by the interaction of multiple genetic, environmental, and lifestyle factors. Some of these factors have been identified, but many remain unknown. Changes in several genes are being studied as possible risk factors for multiple system atrophy.
Is multiple system atrophy the same as multiple sclerosis?
Multiple system atrophy (MSA) and multiple sclerosis (MS) are progressive neurological disorders with overlapping clinical signs and symptoms. However, due to the course of the disease and the age of onset both disorders are rarely differential diagnosis for each other.
What is MSA Parkinson’s?
Multiple system atrophy- parkinsonian type (MSA-P) is a rare condition that causes symptoms similar to Parkinson disease. However, people with MSA-P have more widespread damage to the part of the nervous system that controls important functions such as heart rate, blood pressure, and sweating.
