The peak onset of MSA is between 55-60 years of age, with a range from 30 to over 90 years.
Symptoms of multiple system atrophy (MSA) Symptoms of MSA usually start when someone is between 50 and 60 years of age, but they can begin at any time after 30. The symptoms are wide-ranging and include muscle control problems, similar to those of Parkinson's disease.
Multiple system atrophy (MSA) is a disabling neurodegenerative condition with heterogeneous clinical presentations that typically begins in the sixth decade of life. The disease rarely manifests prior to age 40, and we simply do not know much about the clinical features of these young-onset patients.
The cause of MSA-C in people with the sporadic form is not known. The disease slowly gets worse (is progressive). MSA-C is slightly more common in men than in women. The average age of onset is 54 years old.
For a diagnosis of “probable MSA” a patient must have autonomic dysfunction, including otherwise unexplained urinary urgency, frequency, or incomplete emptying, erectile dysfunction in males, or orthostatic blood pressure drop by at least 30 mmHg systolic or 15 mmHg diastolic within 3 min of standing.
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.
Most cases of multiple system atrophy are sporadic, which means they occur in people with no history of the disorder in their family. Rarely, the condition has been reported to run in families; however, it usually does not have a clear pattern of inheritance.
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.
Though dementia is not considered a common characteristic of MSA, cognitive impairment occurs in some patients in the form of loss of verbal memory and verbal fluency1.
The progression of MSA varies, but the condition does not go into remission. As the disorder progresses, daily activities become more difficult. Possible complications include: Breathing problems during sleep.
Polyglutamine (polyQ) diseases such as spinocerebellar ataxias (SCA1, SCA2, SCA3, SCA6, SCA17, DRPLA) and also late-onset Huntington disease (HD) represent the most frequent genetic misdiagnosis due to the considerable clinical overlap with MSA [5].
MRI is useful and indispensable in the diagnosis of MSA and also possibly for monitoring disease progression.
People typically live about 7 to 10 years after multiple system atrophy symptoms first appear. However, the survival rate with MSA varies widely. Death is often due to respiratory problems, infections or blood clots in the lungs (pulmonary embolus).
Around 3,000 people in Australia currently live with the rare parkinsonian condition called Multiple Systems Atrophy (MSA), which affects movement, breathing, blood pressure and other body functions.
PD and MSA patients are prone to pain with insufficient treatment.
Brain imaging scans, such as an MRI , can show signs that may suggest MSA and also help determine if there are other causes that may be contributing to your symptoms.
In this unselected referral autopsy series of patients with antemortem diagnoses of MSA, the diagnostic accuracy was about 62%, which is within the range of other autopsy series.
Appetite reduces and weight loss is apparent. Communication becomes too effortful and breathing more bubbly or shallow. Dying is very rarely a dramatic event. In the majority of cases it is an increasing winding down of all bodily functions and everything stopping, death occurring in a peaceful and dignified manner.
Listen, listen, listen: Living with MSA can be very isolating. The family may be eager to talk about what they are going through so listening and showing empathy can be one of the most helpful things you can do. Or they may just want a light, fun evening with laughter. Pay attention to their cues and follow their lead.
Multiple system atrophy is a rare condition. Experts estimate an average of 0.6 to 0.7 new cases per 100,000 people yearly. The estimated number of total cases is between 3.4 and 4.9 per 100,000 people.
Whilst MSA doesn't cause loss of sight, there are several symptoms that can occur. People living with MSA may display abnormal eye movements. Most commonly, this is a consequence of impaired or absent convergence, which is the ability to focus both eyes together. This may result in blurred or double vision.
In general, life expectancy is shorter than usual for Cerebellar Degenerative Ataxia patients. Many, however, may live into their 50s or even their 60s.
Its symptoms often mimic those of Parkinson's disease and ataxia. There is no cure, and many physicians are not familiar with the condition – meaning MSA is often misdiagnosed. However, symptoms can be managed, which is why it's important to be evaluated and treated by physicians who have experience dealing with MSA.
