Physical therapy. Stretching and strengthening exercises can help maintain muscle strength, flexibility and range of motion, and prevent joint immobility. Heating pads can help relieve muscle pain. Speech therapy. If your facial muscles are affected by PLS, speech therapy might help.
What is the best treatment for PLS?
Treatment of primary lateral sclerosis involves the use of drugs to help control specific symptoms. Baclofen and tizanidine may be prescribed for spasticity, quinine for cramps, and diazepam, a drug that relaxes muscles, for muscular contractions.
How is primary lateral sclerosis (PLS) treated?
Because amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease) is more well known, and because the two diseases often manifest similar symptoms, PLS is often confused with ALS. 4 There is no cure at the moment for PLS, so treatment is focused on relieving the symptoms of the disorder.
Can PLS be treated like ALS?
PLS affects the nerve cells in the body that control voluntary movement of muscles, called motor neurons. Over time, these motor neurons lose their ability to function, causing painless but progressive weakness and stiffness of the muscles.
How does PLS affect the body?
What is the life expectancy of a person with PLS?
PLS has not been considered to shorten life expectancy. However, inspection of reported survival data from 36 patients with PLS now suggests that the median survival is approximately 20 years.
What are the stages of PLS?
The three subtypes classified by pattern of progression are grouped: ascending (PLS-A), multifocal (PLS-M) and sporadic paraparesis (PLS-SP).
Does PLS lead to ALS?
ALS may begin with signs of only upper or lower motor neuron involvement, so a process that begins with upper motor neuron degeneration and that initially is considered to be PLS has the potential to be reclassified as ALS if suffi- cient signs of both upper and lower motor neuron involvement develop over time.
What causes PLS disease?
Juvenile PLS is caused by mutations in a gene called ALS2. Although researchers don't understand how this gene causes the disease, they know that the ALS2 gene gives instructions for creating a protein called alsin, which is present in motor neuron cells.
Is PLS treatable?
There are no treatments to prevent, stop or reverse primary lateral sclerosis.
Does PLS show on MRI?
26 Our findings in PLS match this second explanation. In patients with PLS MRI shows atrophy of the frontoparietal part of the brain, most evident in the precentral area, with concomitant degeneration of the underlying white matter. 2 6 10 This can be seen most clearly on images in the parasagittal plane.
Can PLS cause death?
PLS is not fatal. There is no cure and the progression of symptoms varies. Some people may retain the ability to walk without assistance, but others eventually require wheelchairs, canes, or other assistive devices.
What are the first symptoms of PLS?
The first symptoms of PLS typically include:Stiffness (from spasticity) and weakness in your leg muscles.Difficulty walking or maintaining your balance.Intermittent muscle spasms (sudden marked stiffening) of voluntary muscles, which can be painful due to the spasms.
Is PLS inherited?
In most cases, it occurs sporadically in people with no family history of the condition. A subtype of PLS, called juvenile PLS, is caused by changes in the ALS2 gene and is inherited in an autosomal recessive manner.
What does PLS feel like?
Primary lateral sclerosis (PLS) is a rare, neuromuscular disorder that affects the central motor neurons and is characterized by progressive weakness and stiffness of the muscles of the legs. Such weakness may progress to affect the arms and the muscles at the base of the brain (bulbar muscles).
How long does early stage ALS last?
Gradually all voluntary muscles are affected, and individuals lose their strength and the ability to speak, eat, move, and even breathe. Most people with ALS die from respiratory failure, usually within 3 to 5 years from when the symptoms first appear.
Where does PLS end?
PLS results in the slow degeneration (breakdown) of the UMN, which ends in the center of the spinal cord on a second set of motor neurons. Normally, messages are then relayed from these spinal cord neurons along nerve fibers to the voluntary muscles (muscles under your direct control), which together make up the lower motor neuron (LMN).
What are the symptoms of lateral sclerosis?
The first symptoms of PLS typically include: Stiffness (from spasticity) and weakness in your leg muscles.
How old is too old to get lateral sclerosis?
Anyone can develop primary lateral sclerosis (PLS). The condition is most likely to affect individuals between the ages of 35 and 66, and usually by about 50 years old.
Why is progression faster in ALS?
In general, both the speed of progression and extent of disease are greater in ALS possibly because both levels of motor neurons degenerate. Importantly, some forms of ALS mainly affect the UMN (at least at first), and progress more slowly, making it difficult to distinguish from PLS, especially in early stages.
Is there a cure for PLS?
Symptoms of PLS, like muscle stiffness and weakness, usually begin in the legs but over time, spread throughout your body. Because there is no cure for PLS, treatment centers on managing your symptoms, providing support, and improving the quality of your life. Cleveland Clinic is a non-profit academic medical center.
Is there a cure for lateral sclerosis?
Unfortunately, primary lateral sclerosis (PLS) does not have a cure. Treatment is aimed at managing symptoms and may include: Medications to reduce muscle spasticity (stiffness), spasms, and difficulties swallowing saliva or controlling emotions ( pseudobulbar affect [PBA]). Physical therapy to improve muscle flexibility and joint range of motion.
What is PLS in medical terms?
Updated on December 06, 2019. Primary lateral sclerosis (PLS) is a progressive degenerative motor neuron disease.

What are the symptoms of lateral sclerosis?
Muscle spasms in the hands or at the base of the brain. Trouble moving the arms and doing tasks such as combing hair or brushing teeth. Loss of bladder control late in the course of primary lateral sclerosis 3 . The symptoms slowly get worse over time.
Does lateral sclerosis affect the mind?
Primary lateral sclerosis brings progressive disability and loss of function but does not affect the mind or shorten the lifespan of patients directly. For this reason, support groups such as the Spastic Paraplegia Foundation for patients and their families is key to adapting to the physical and emotional burdens of the disease.
Is PLS the same as ALS?
Because amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease) is more well known, and because the two diseases often manifest similar symptoms, PLS is often confused with ALS. 4 .
What is stem cell therapy?
Stem cell therapy is considered to be an alternative method for treating Primary Lateral Sclerosis (PLS) and other neurodegenerative disorders. Stem cell transplantation is a potential therapeutic strategy not only via cell replacement but also by modification of the extracellular motor neuronal environment, through a trophic ...
Why are MSCs used in ALS?
Mesenchymal Stem Cells (MSCs) are very attractive multipotent stem cells for ALS cell therapy because of their great plasticity and their ability to provide the host tissue with growth factors and to modulate the host immune system.

Can genetic factors cause PLS?
The research team hopes to determine whether genetic factors may predispose an individual to a disease such as PLS and whether sporadic motor-neuron diseases may be the result of not one but several genetic factors. Blood samples from patients and their living parents, brothers, and sisters are needed for this study.
Does lateral sclerosis affect the hands?
Although primary lateral sclerosis begins in the legs, it progresses to affect the muscles of the hands and at the base of the brain. As a result, affected individuals may also exhibit difficulty forming words (dysarthria) and difficulty swallowing (dysphagia). In some cases, these symptoms may precede the development of muscle weakness in the legs.
